Businesses, governments, and researchers continue to struggle with extracting usable data from PDF files, despite AI advances. These digital documents contain valuable information for everything from scientific research to government records, but their rigid formats make extraction difficult.

"PDFs are a creature of a time when print layout was a big influence on publishing software," Derek Willis, a lecturer in Data and Computational Journalism at the University of Maryland, told ArsTechnica. This print-oriented design means many PDFs are essentially "pictures of information" requiring optical character recognition (OCR) technology.

Traditional OCR systems have existed since the 1970s but struggle with complex layouts and poor-quality scans. New AI language models from companies like Google and Mistral now attempt to process documents more holistically, with varying success. "Right now, the clear leader is Google's Gemini 2.0 Flash Pro Experimental," Willis notes, while Mistral's recent OCR solution "performed poorly" in tests.

An anonymous reader quotes a report from the BBC: A former senior Facebook executive has told the BBC how the social media giant worked "hand in glove" with the Chinese government on potential ways of allowing Beijing to censor and control content in China. Sarah Wynn-Williams -- a former global public policy director -- says in return for gaining access to the Chinese market of hundreds of millions of users, Facebook's founder, Mark Zuckerberg, considered agreeing to hiding posts that were going viral, until they could be checked by the Chinese authorities.

Ms Williams -- who makes the claims in a new book -- has also filed a whistleblower complaint with the US markets regulator, the Securities and Exchange Commission (SEC), alleging Meta misled investors. The BBC has reviewed the complaint. Facebook's parent company Meta, says Ms Wynn-Williams had her employment terminated in 2017 "for poor performance." It is "no secret we were once interested" in operating services in China, it adds. "We ultimately opted not to go through with the ideas we'd explored." Meta referred us to Mark Zuckerberg's comments from 2019, when he said: "We could never come to agreement on what it would take for us to operate there, and they [China] never let us in."

Facebook also used algorithms to spot when young teenagers were feeling vulnerable as part of research aimed at advertisers, Ms Wynn-Williams alleges. A former New Zealand diplomat, she joined Facebook in 2011, and says she watched the company grow from "a front row seat." Now she wants to show some of the "decision-making and moral compromises" that she says went on when she was there. It is a critical moment, she adds, as "many of the people I worked with... are going to be central" to the introduction of AI. In her memoir, Careless People, Ms Wynn-Williams paints a picture of what she alleges working on Facebook's senior team was like.

Internet shutdowns in Africa hit a record high in 2024, with 21 shutdowns across 15 countries. The previous record was 19 shutdowns in 2020 and 21. The Guardian reports: Authorities in Comoros, Guinea-Bissau and Mauritius joined repeat offenders such as Burundi, Ethiopia, Equatorial Guinea and Kenya. Guinea, Nigeria, Senegal and Tanzania were also on the list. But perpetrators also included militias and other non-state actors. Telecommunication and internet service providers who shut services based on government orders are also complicit in violating people's rights, said Felicia Anthonio, the #KeepItOn campaign manager at Access Now, citing the UN guiding principles on business and human rights.

The details showed that most of the shutdowns were imposed as a response to conflicts, protests and political instability. There were also restrictions during elections. [...] At least five shutdowns in Africa had been imposed for more than a year by the end of 2024, according to Access Now. As of early 2025, the social network Meta was still restricted in Uganda, despite authorities engaging with its representatives. On the Equatorial Guinean island of Annobon, internet and cell services have been cut off since an August 2024 protest over environmental concerns and isolation from the rest of the country. The increase in shutdowns led the African Commission on Human and Peoples' Rights to pass a landmark resolution in March 2024 to help reverse the trend.

The US will be "central" to solving the climate crisis despite Donald Trump's withdrawal of government support and cash, the president of the next UN climate summit has said. From a report: Andre Correa do Lago, president-designate of the Cop30 summit for the host country, Brazil, hinted that businesses and other organisations in the US could play a constructive role without the White House. "We have no idea of ignoring the US," he told journalists on a call on Friday. "The US is a key country in this exercise. There is the US government, which will limit its participation [but] the US is a country with such amazing technology, amazing innovation -- this is the US that can contribute. The US is a central country for these discussions and solutions."

Brazil has also vowed to hold an "ethical stocktake" aimed at examining climate justice issues, for poor and vulnerable people, and to give Indigenous people a key role at the talks. Correa do Lago wrote to all UN countries on Monday, setting out Brazil's expectations that all governments will draw up national plans for steep cuts in greenhouse gas emissions before the conference starts in Belem, a rainforest city at the mouth of the Amazon, in November.

Sony has removed more than 75,000 AI-generated deepfake songs mimicking artists including Harry Styles and Beyonce from online platforms, the company revealed in a submission to the UK government, adding this likely represents just a fraction of fake songs circulating online.

The proliferation of these unauthorized AI replicas has caused "direct commercial harm to legitimate recording artists, including UK artists," Sony stated. The company's intervention comes as Britain considers new copyright legislation that would permit AI companies to train models using artist material, a proposal that would require rights holders to opt out rather than requiring permission.

AmiMoJo writes: In September 2023, KrebsOnSecurity published findings from security researchers who concluded that a series of six-figure cyberheists across dozens of victims resulted from thieves cracking master passwords stolen from the password manager service LastPass in 2022. In a court filing last week, U.S. federal agents investigating a spectacular $150 million cryptocurrency heist said they had reached the same conclusion.

On March 6, federal prosecutors in northern California said they seized approximately $24 million worth of cryptocurrencies that were clawed back following a $150 million cyberheist on Jan. 30, 2024. The complaint refers to the person robbed only as 'Victim-1,' but according to blockchain security researcher ZachXBT the theft was perpetrated against Chris Larsen, the co-founder of the cryptocurrency platform Ripple.

ZachXBT was the first to report on the heist, of which approximately $24 million was frozen by the feds before it could be withdrawn. This week's action by the government merely allows investigators to officially seize the frozen funds. But there is an important conclusion in this seizure document: It basically says the U.S. Secret Service and the FBI agree with the findings of the LastPass breach story published here in September 2023.

August, 2023: Thousands of Crypto Scammers are Enslaved by Human-Trafficking Gangsters, Says Bloomberg Reporter. ("They'd lure young people from across Southeast Asia...with the promise of well-paying jobs in customer service or online gambling.")

February, 2025: A coordinated response begins by Thai, Chinese and Myanmar authorities, which includes cutting power, internet, and fuel supplies to the scam centers.

Today: The Associated Press reports that thousands of the people liberated from locked compounds in Myanmar now "have found themselves trapped once again, this time in overcrowded facilities with no medical care, limited food and no idea when they'll be sent home." Thousands of sick, exhausted and terrified young men and women, from countries all over the world squat in rows, packed shoulder to shoulder, surgical masks covering their mouths and eyes. Their nightmare was supposed to be over... The armed groups who are holding the survivors, as well as Thai officials across the border, say they are awaiting action from the detainees' home governments. It's one of the largest potential rescues of forced laborers in modern history, but advocates say the first major effort to crack down on the cyber scam industry has turned into a growing humanitarian crisis...

An unconfirmed list provided by authorities in Myanmar says they're holding citizens from 29 countries including Philippines, Kenya and the Czech Republic. Authorities in Thailand say they cannot allow foreigners to cross the border from Myanmar unless they can be sent home immediately, leaving many to wait for help from embassies that has been long in coming. China sent a chartered flight Thursday to the tiny Mae Sot airport to pick up a group of its citizens, but few other governments have matched that. There are roughly 130 Ethiopians waiting in a Thai military base, stuck for want of a $600 plane ticket. Dozens of Indonesians were bused out one morning last week, pushing suitcases and carrying plastic bags with their meager possessions as they headed to Bangkok for a flight home... The recent abrupt halt to U.S. foreign aid funding has made it even harder to get help to released scam center workers...

It's not clear how much of an effect these releases will have on the criminal groups that run the scam centers. February marked the third time the Thais have cut internet or electricity to towns across the river. Each time, the compounds have managed to work around the cuts. Large compounds have access to diesel-powered generators, as well as access to internet provider Starlink, experts working with law enforcement say.
The article also points out that "The people released are just a small fraction of what could be 300,000 people working in similar scam operations across the region, according to an estimate from the United States Institute of Peace. Human rights groups and analysts add that the networks that run these illegal scams will continue to operate unless much broader action is taken against them..."

"The United Nations Office on Drugs and Crimes estimates that between $18 billion and $37 billion was lost in Asia alone in 2023, with minimal government action against the criminal industry's spread."

The Washington Post reports: Meta was willing to go to extreme lengths to censor content and shut down political dissent in a failed attempt to win the approval of the Chinese Communist Party and bring Facebook to millions of internet users in China, according to a new whistleblower complaint from a former global policy director at the company.

The complaint by Sarah Wynn-Williams, who worked on a team handling China policy, alleges that the social media giant so desperately wanted to enter the lucrative China market that it was willing to allow the ruling party to oversee all social media content appearing in the country and quash dissenting opinions. Meta, then called Facebook, developed a censorship system for China in 2015 and planned to install a "chief editor" who would decide what content to remove and could shut down the entire site during times of "social unrest," according to a copy of the 78-page complaint exclusively seen by The Washington Post.

Meta chief executive Mark Zuckerberg also agreed to crack down on the account of a high-profile Chinese dissident living in the United States following pressure from a high-ranking Chinese official the company hoped would help them enter China, according to the complaint, which was filed in April to the Securities and Exchange Commission [SEC]. When asked about its efforts to enter China, Meta executives repeatedly "stonewalled and provided nonresponsive or misleading information" to investors and American regulators, according to the complaint.

Wynn-Williams bolstered her SEC complaint with internal Meta documents about the company's plans, which were reviewed by The Post. Wynn-Williams, who was fired from her job in 2017, is also scheduled to release a memoir this week documenting her time at the company, titled "Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism." According to a memo in the complaint, Meta leaders faced aggressive pressure by Chinese government officials to host Chinese users' data to local data centers, which Wynn-Williams alleges would have made it easier for the Chinese Communist Party to covertly obtain the personal information of its citizens.
Wynn-Williams told the Washington Post that "for many years Meta has been working hand in glove with the Chinese Communist Party, briefing them on the latest technological developments and lying about it."

Reached for a comment, Meta spokesman Andy Stone told the Washington Post it was "no secret" they'd been interested in operating in China. "This was widely reported beginning a decade ago. We ultimately opted not to go through with the ideas we'd explored, which Mark Zuckerberg announced in 2019." Although the Post shares new details about what a Facebook privacy policy staffer offer China in negotations in 2014. ("In exchange for the ability to establish operations in China, FB will agree to grant the Chinese government access to Chinese users' data — including Hongkongese users' data.")

The Post also describes one iteration of a proposed agreement in 2015. "To aid the effort, Meta built a censorship system specially designed for China to review, including the ability to automatically detect restricted terms and popular content on Facebook, according to the complaint...

"In 2017, Meta covertly launched a handful of social apps under the name of a China-based company created by one of its employees, according to the complaint."

Last week Google urged the U.S. government not to break up the company — but apparently, it didn't work.
In a new filing Friday, America's Justice Department "reiterated its November proposal that Google be forced to sell its Chrome web browser," reports the Washington Post, "to address a federal judge finding the company guilty of being an illegal monopoly in August." The government also kept a proposal that Google be banned from paying other companies to give its search engine preferential placement on their apps and phones. At the same time, the government dropped its demand that Google sell its stakes in AI start-ups after one of the start-ups, Anthropic AI, argued that it needed Google's money to compete in the fast-growing industry.

The government's final proposal "reaffirms that Google must divest the Chrome browser — an important search access point — to provide an opportunity for a new rival to operate a significant gateway to search the internet, free of Google's monopoly control," Justice Department lawyers wrote in the filing... Judge Amit Mehta, of the U.S. District Court for the District of Columbia, who had ruled that Google held an illegal monopoly, will decide on the final remedies in April.
The article quotes a Google spokesperson's response: that the Justice Department's "sweeping" proposals "continue to go miles beyond the court's decision, and would harm America's consumers, economy and national security."

U.S. president Donald Trump called Daylight Saving Time "very costly to our nation" and "inconvenient" in December. Today the Washington Post remembers he'd vowed his Republican party would use their "best efforts" to eliminate it.

But it's still proving to be politically difficult... Polls have shown that most Americans oppose the time shifts but disagree on what should replace them... [U.S. political leaders] also say they are grappling with whether the nation should permanently move the clocks forward one hour, an idea championed by lawmakers on the coasts who say it would allow for more sunshine during the winter, or remain on year-round standard time, which is favored by neurologists who say it aligns with our circadian rhythms. That decision would rest with Congress, not the president. The split often reflects regional, not political, differences, based on where time zones fall; a year-round "spring forward" would mean winter sunrises that could creep past 9 a.m. in cities such as Indianapolis and Detroit, prompting many local lawmakers to oppose the idea...

[A 2022 Senate vote to make Daylight Saving Time permanent] awoke a new lobbying effort from advocates such as the American Academy of Sleep Medicine, which warned that year-round daylight saving time would be unhealthy, citing risks such as higher rates of obesity or metabolic dysfunction. Some researchers warned of a condition dubbed "social jetlag," saying that internal body clocks and rhythms would be persistently misaligned if human clocks were permanently set forward an hour. The concerted resistance from the health groups — which some congressional aides jokingly referred to as "Big Sleep" — helped kill the measure in the House and has contributed to a stalemate over how to proceed...

Today, roughly two-thirds of Americans want to end the clock changes, polls show. But even those Americans don't agree on what should come next. An October 2023 YouGov poll found that 33 percent of respondents wanted year-round daylight saving time, 23 percent wanted permanent standard time, and 9 percent had no preference. The remainder weren't sure or preferred to remain on the current system... The political fight is far from over, with Trump allies such as Sen. Tommy Tuberville (R-Alabama) pledging to keep pushing for year-round daylight saving time. Some congressional Republicans also have privately called for a hearing in front of the House Energy and Commerce Committee, with hopes of advancing the Sunshine Protection Act.

President Trump has signed an executive order to establish a strategic reserve of cryptocurrencies by using tokens already owned by the government. Reuters reports: A "Strategic Bitcoin Reserve" will be capitalized with bitcoin owned by the federal government that was seized as part of criminal or civil asset forfeiture proceedings, the White House crypto czar, billionaire David Sacks, said in a post on social media platform X. The order kept open the possibility of the government buying bitcoin in future. The U.S. commerce and treasury secretaries "are authorized to develop budget-neutral strategies for acquiring additional bitcoin, provided that those strategies impose no incremental costs on American taxpayers," a factsheet on the White House website said. "This is the most underwhelming and disappointing outcome we could have expected for this week," Charles Edwards, founder of bitcoin-focused hedge fund Capriole Investments, wrote in a post on X. "No active buying means this is just a fancy title for Bitcoin holdings that already existed with the Govt. This is a pig in lipstick."

The White House is weighing measures to restrict Chinese artificial-intelligence upstart DeepSeek, including banning its chatbot from government devices because of national-security concerns, WSJ reported Friday, citing people familiar with the matter. From the report: U.S. officials are worried about DeepSeek's handling of user data, which the Chinese company says it stores in servers located in China, the people said. Officials also believe DeepSeek hasn't sufficiently explained how it uses the data it collects and who has access to the data, they said.

The Trump administration is likely to adopt a rule that would bar people from downloading DeepSeek's chatbot app onto U.S. government devices, the people said. Officials are also considering two other possible moves: banning the DeepSeek app from U.S. app stores and putting limits on how U.S.-based cloud service providers could offer DeepSeek's AI models to their customers, people close to the matter said. They cautioned that discussions about these two moves were still at an early stage.

The U.S. Citizenship and Immigration Services (USCIS) is proposing to expand mandatory social media screening, currently required only for new arrivals, to include all non-citizens already residing in the U.S. who apply for immigration benefits. The Register reports: Back in 2019, the Department of Homeland Security, which runs USCIS, decided anyone looking to enter the US on a work visa or similar had to hand over their social media handles to the authorities so that they could be looked over for wrongdoing and subversion. In fact, this goes back to 2014, at least, to one degree or another, and has been standard procedure for years for foreigners, particularly those coming in on a visa. [...]

On January 20 this year, President Trump signed an executive order calling for much tougher vetting of foreign aliens, and in response, USCIS has proposed rules saying those already in the country who are going through some process with the agency -- such as applying for permanent residency or citizenship -- will have their social media scanned for subversion. That means if you came to America before foreigners' internet presence was screened as it now is, and you're now seeking some kind of immigration benefit, at this rate you'll be subject to the same scanning as those entering the Land of the Free today. The proposed changes have a 60-day comment period for the public to suggest amendments. The last day to send them in is May 5.

An anonymous reader quotes a report from Reuters: The U.S. House Judiciary Committee subpoenaed Alphabet on Thursday seeking its communications with former President Joe Biden's administration about content moderation policies. House Judiciary Committee Chairman Jim Jordan, a Republican, also asked the YouTube parent company for similar communications with companies and groups outside government, according to a copy of the subpoena seen by Reuters. The subpoena seeks communications about limits or bans on content about President Donald Trump, Tesla CEO and close Trump ally Elon Musk, the virus that causes COVID-19 and a host of other conservative discussion topics. "Alphabet, to our knowledge, has not similarly disavowed the Biden-Harris Administration's attempts to censor speech," Jordan said in a letter.

Meanwhile, Google spokesperson Jose Castaneda said the company will "continue to show the committee how we enforce our policies independently, rooted in our commitment to free expression."

An anonymous reader quotes a report from Ars Technica: The Trump administration is eliminating a preference for fiber Internet in a $42.45 billion broadband deployment program, a change that is expected to reduce spending on the most advanced wired networks while directing more money to Starlink and other non-fiber Internet service providers. One report suggests Starlink could obtain $10 billion to $20 billion under the new rules. Secretary of Commerce Howard Lutnick criticized the Biden administration's handling of the Broadband Equity, Access, and Deployment (BEAD) program in a statement yesterday. Lutnick said that "because of the prior Administration's woke mandates, favoritism towards certain technologies, and burdensome regulations, the program has not connected a single person to the Internet and is in dire need of a readjustment."

The BEAD program was authorized by Congress in November 2021, and the US was finalizing plans to distribute funding before Trump's inauguration. The National Telecommunications and Information Administration (NTIA), part of the Commerce Department, developed rules for the program in the Biden era and approved initial funding plans submitted by every state and territory. The program has been on hold since the change in administration, with Senator Ted Cruz (R-Texas) and other Republicans seeking rule changes. In addition to demanding an end to the fiber preference, Cruz wants to kill a requirement that ISPs receiving network-construction subsidies provide cheap broadband to people with low incomes. Cruz also criticized "unionized workforce and DEI labor requirements; climate change assessments; excessive per-location costs; and other central planning mandates."

Lutnick's statement yesterday confirmed that the Trump administration will end the fiber preference and replace it with a "tech-neutral" set of rules, and explore additional changes. He said: "Under my leadership, the Commerce Department has launched a rigorous review of the BEAD program. The Department is ripping out the Biden Administration's pointless requirements. It is revamping the BEAD program to take a tech-neutral approach that is rigorously driven by outcomes, so states can provide Internet access for the lowest cost. Additionally, the Department is exploring ways to cut government red tape that slows down infrastructure construction. We will work with states and territories to quickly get rid of the delays and the waste. Thereafter we will move quickly to implementation in order to get households connected." Lutnick said the department's goal is to "deliver high-speed Internet access... efficiently and effectively at the lowest cost to taxpayers."

The U.K. government appears to have quietly scrubbed encryption advice from government web pages, just weeks after demanding backdoor access to encrypted data stored on Apple's cloud storage service, iCloud. From a report: The change was spotted by security expert Alec Muffett, who wrote in a blog post on Wednesday that the U.K.'s National Cyber Security Centre (NCSC) is no longer recommending that high-risk individuals use encryption to protect their sensitive information.

The NCSC in October published a document titled "Cybersecurity tips for barristers, solicitors & legal professionals," that advised the use of encryption tools such as Apple's Advanced Data Protection (ADP). ADP allows users to turn on end-to-end encryption for their iCloud backups, effectively making it impossible for anyone, including Apple and government authorities, to view data stored on iCloud. The URL hosting the NCSC document now redirects to a different page that makes no mention of encryption or ADP. Instead, it recommends that at-risk individuals use Apple's Lockdown Mode, an "extreme" security tool that restricts access to certain functions and features.

AmiMoJo writes: China plans to issue guidance to encourage the use of open-source RISC-V chips nationwide for the first time, Reuters reports, citing two sources briefed on the matter, as Beijing accelerates efforts to curb the country's dependence on Western-owned technology.

The policy guidance on boosting the use of RISC-V chips could be released as soon as this month, although the final date could change, the sources said. It is being drafted jointly by eight government bodies, including the Cyberspace Administration of China, China's Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the China National Intellectual Property Administration, they added.

Geoffrey.landis writes: Over the last three months of 2024, more than 800 cases of GPS interference were recorded in Lithuanian airspace. Estonia and Finland have also raised concerns, accusing Russia of deploying technology to jam satellite navigation signals near Nato's eastern flank.

A group of British scientists -- dubbed the "Time Lords" -- are working on a solution: to develop portable atomic clocks. By carrying a group of atoms cooled to -273C on the plane itself, rather than relying on an external signal, the technology can't be interfered with by jamming. But the problem is that the equipment is still too large to be used routinely on planes.

The UK Hub for Quantum Enabled Position Navigation and Timing (QEPNT) was set up last December by the government to shrink the devices on to a chip, making them robust enough for everyday life and affordable for everyone. Henry White, part of the team from BAE Systems that worked on the test flight, told BBC News that he thought the first application could be aboard ships, "where there's a bit more space".

Microsoft warned that an advanced Chinese hacking group is waging a campaign of supply-chain attacks. From a report: The company's threat intelligence division said in a blog post Wednesday that the group, known as Silk Typhoon, was targeting remote management tools and cloud applications in order to spy on a range of companies and organizations in the US and abroad.

Microsoft said it observed in late 2024 that hackers were targeting cloud storage services, from which they would steal keys that could be used to access customer data. The group breached state and local government organizations and companies in the technology sector, seeking information on US government policy and documents related to law enforcement investigations. Silk Typhoon was behind a December hack that targeted the US Treasury Department, compromising more than 400 computers, Bloomberg News previously reported.

Google is urging officials at President Donald Trump's Justice Department to back away from a push to break up the search engine company, citing national security concerns, Bloomberg reported Wednesday, citing sources familiar with the discussions. From the report: Representatives for the Alphabet unit asked the government in a meeting last week to take a less aggressive stance as the US looks to end what a judge ruled to be an illegal online search monopoly, said the people, who asked not to be identified discussing the private deliberations. The Biden administration in November had called for Google to sell its Chrome web browser and make other changes to its business including an end to billions of dollars in exclusivity payments to companies including Apple.

Although Google has previously pushed back on the Biden-era plan, the recent discussions may preview aspects of the company's approach to the case as it continues under the Trump administration. A federal judge is set to rule on how Google must change its practices following hearings scheduled for next month. Both sides are due to file their final proposals to the judge on Friday.
