A group of Cornell computer scientists has unveiled what they believe could be a new tool in the fight against AI‑generated video, deepfakes and doctored clips.

The watermarking technique, called “noise‑coded illumination,” hides verification data in light itself to help investigators spot doctored videos. The approach, devised by Peter Michael, Zekun Hao, Serge Belongie and assistant professor Abe Davis, was published in the June 27 issue of ACM Transactions on Graphics and will be presented by Michael at SIGGRAPH on August 10.

The system adds a barely perceptible flicker to light sources in a scene. Cameras record this pseudo-random pattern even though viewers cannot detect it, and each lamp or screen that flickers carries its own unique code.

As an example, imagine a press conference filmed in the White House briefing room. The studio lights would be programmed to flicker with unique codes. If a viral clip from that press conference later circulates with what appears to be an inflammatory statement, investigators can run it through a decoder, and by checking whether the recorded light codes line up, could determine whether the footage was doctored.

“Each watermark carries a low‑fidelity, time‑stamped version of the unmanipulated video under slightly different lighting. We call these code videos,” said Abe Davis, assistant professor of computer science at Cornell. “When someone manipulates a video, the manipulated parts start to contradict what we see in these code videos, which lets us see where changes were made. And if someone tries to generate fake video with AI, the resulting code videos just look like random variations.”

While the scientists acknowledge that rapid motion and strong sunlight can hinder the technique’s efficacy, they are bullish on its utility in settings like conference‑room presentations, television interviews or lecture‑hall speeches.

YouTube will be included in Australia’s social media ban for children under 16, as reported by Bloomberg. The country’s Labor government said that the site will be subject to the same rules as other leading platforms like Facebook, Instagram, TikTok and X when the legislation goes into effect this December.

Australia had planned to exempt YouTube from the forthcoming social media ban, on the grounds that it’s an educational tool. This irked other platforms, with Meta and TikTok urging the country’s government to backtrack on the exclusion.

This move didn’t sit too well with YouTube and parent company Alphabet. A company spokesperson told CNN that this decision “reverses a clear, public commitment” from the government to treat the platform as an educational tool. YouTube Kids isn’t included in the ban because it doesn’t allow users to upload videos or comment.

The government said this reversal was largely influenced by a survey released by Australia’s independent online regulator, the eSafety Commission. It found that 37 percent of children surveyed had reported seeing harmful content on YouTube. This includes stuff like dangerous online challenges, fight videos and hateful rhetoric.

Communications Minister Anika Wells recently spoke to the Australian Parliament and noted that “YouTube uses the same persuasive design features as other social media platforms, like infinite scroll, like autoplay and algorithmic feed.” She went on to say that she accepted the results of the aforementioned survey and that YouTube “should not be treated differently from other social media platforms.”

The ban originally passed at the tail-end of last year, though some of the details have yet to be ironed out. The government has until December to finalize everything. We do know that the ban puts the onus on the actual platforms to prevent children from opening up accounts, as they’ll face hefty fines of up to nearly $50 million Australian dollars ($32 million USD) if they don’t comply.

“Kids, God bless them, are going to find a way around this. Maybe they’re all going to swarm on LinkedIn. We don’t know,” Minister Wells said. My hunch is that it’ll be more VPN than LinkedIn.

The next season of Apex Legends kicks off on August 5, and it will see the arrival of a new, permanent game mode. Respawn says it built Wildcard as a faster-paced alternative to the core battle royale mode. For instance, when you take out an enemy, they won’t leave behind a death box. Instead, their loot will scatter around them, making it easier for you to spot and pick up an item you need or want.

Another big difference here is legend stacking. You and your teammates will all be able to play as the same character, if you like. Respawn has retooled the Kings Canyon map for Wildcard, adding ziplines, gravity cannons and other fun stuff to the playground. Second chances will give you another opportunity to pick up the win if things don’t pan out for you at first.

It’s highly likely that Wildcard has been in the works for quite a while, but it’s a bit unfortunate for Respawn that it’s debuting the mode several weeks after Epic Games added a new, faster-paced battle royale option of its own to Fortnite. Rounds of Blitz Royale — which Epic designed primarily for mobile devices — can last just a few minutes each. Still, it’s probably been a couple of years since I last played Apex, and Wildcard has me intrigued enough to dive back in.

There are plenty of other updates coming to Apex when the Showdown season starts, of course. Caustic will have a new ability called Field Research, while his gas canisters and grenades will deal more damage. Meanwhile, Bangalore’s smoke canister will be able to breach doors and gain an EMP upgrade. In addition, Respawn is retooling the mid-to-late game with powerful passive abilities called Amps. These will allow you to unlock boosts like infinite ammo, extra armor and healing upgrades.

Amazon’s AI licensing deal with The New York Times is worth $20 million to $25 million per year, according to The Wall Street Journal. The two companies did not disclose the fiscal terms of the agreement back when it was announced in May. The Journal’s reporting provides a rare insight into the value of a media company licensing its content for AI training.

In the case of The Times, Amazon’s annual payments to the publisher would amount to nearly one percent of its total revenue in 2024. In return, the agreement allows Amazon to train its AI models on content from The Times, including content from auxiliary arms of the company like The Athletic and NYT Cooking. It also allows Amazon to offer summaries and excerpts from the paper through Alexa.

In light of that, $20 million to $25 million per year seems a small payout when the threat AI poses to publishers is so great, and other media companies have been able to negotiate bigger payouts. For instance, OpenAI’s five-year licensing deal with News Corp, the owner of The Wall Street Journal, is reportedly worth more than $250 million.

The New York Times sued OpenAI and Microsoft for training their models on the company’s content without permission back in 2023. That case is still ongoing.

Google says it will sign the European Union’s new AI Code of Practice, which provides a framework for compliance with the EU’s AI Act. The act itself was passed in 2024, but its many provisions will take months to years to come into effect. The non-binding Code of Practice is a voluntary measure intended to help ensure that companies generally meet the obligations laid out by the Act in the meantime.

In a blog post announcing Google’s participation, the tech giant shared some skepticism about the AI Act’s impact on the technology in the EU. The statement reads in part, “While the final version of the Code comes closer to supporting Europe’s innovation and economic goals than where it began — and we appreciate the opportunity we have been provided to submit comments — we remain concerned that the AI Act and Code risk slowing Europe’s development and deployment of AI.”

Just recently, Meta said it would not be signing the Code of Practice. The company’s chief global affairs officer, Joel Kaplan, called the Code an “over-reach.” In a statement, Kaplan said, “Europe is heading down the wrong path on AI.”

The EU’s AI Act is the first of its kind from a major regulator and is comprehensive in its approach. Meanwhile, the United States is in the earliest stages of determining its approach to AI regulation.

Obligations under the EU’s AI Act are being implemented in a staggered fashion, though rules governing general‑purpose AI (GPAI) models will apply on August 2, 2025. Any models brought to market before then must be fully compliant with the rules by August 2, 2027. The current implementation timeline lists assessment and enforcement steps as far out as August 2031.

YouTube has changed its ad guideline policy surrounding swear words, allowing creators a bit more freedom than before. In a video announcement, YouTube’s head of monetization, Conor Kavanagh, said that videos containing stronger profanity such as f-bombs in the first seven seconds are now eligible for full monetization. In 2022, YouTube introduced a policy that would flag videos using profane language in the first several seconds as ineligible for advertising. It relaxed that rule a bit in 2023. Videos containing moderate profanity, such as “asshole” or “bitch,” in the first seven seconds no longer faced restrictions. Those with strong profanity were only eligible to get limited ad revenue. Now, those videos can be fully monetized. 

In his announcement, Kavanagh explained that YouTube introduced its old rules, because advertisers wanted to distance their ads from profanity. But times have changed, and advertisers can now target content based on their desired level of profanity if they want to. He warned, however, that using strong swear words in titles and thumbnails would still limit a video’s advertisements. In addition, using strong profanity too much in one video, such as making a compilation of a fictional character swearing, would still violate the platform’s advertiser-friendly content guidelines. In other words, yes creators can swear in the opening of a video now, but they still have to be mindful if they want the video to earn money.

Apple has submitted its official response to the antitrust lawsuit the Justice Department filed against it last year, which accused the company of having smartphone monopoly and criticized its “walled garden” approach to business. It said that the lawsuit threatens what sets the iPhone apart in a fiercely competitive market, reduce consumer choice, as well as erode competition. In addition, Apple warned that it could set “a dangerous precedent” in allowing the government to “take a heavy hand in designing people’s technology.”

In its filing, as shared by 9to5Mac, Apple responded to every point made by the agency in its complaint. The DOJ said that “Apple stifles the success of ‘super apps,'” or apps that offer multiple services on one platform, but the company’s filing said that its “rules allow and support such apps.” A multitude of them are available on the App Store today, the company added. Apple also denied the department’s allegation that it blocks cloud streaming games and said that it allows game streaming over the web and in the App Store. 

The DOJ’s allegation that it degrades third-party messaging apps is not true, the company also said, and they’re widely available on the iPhone. Apple denied that it limits the functionality of third-party smartwatches and said that they can “effectively pair with iPhone,” as well as “share data to and from the iPhone via a companion app.” Another allegation was that Apple withholds access to iPhone hardware that’s necessary for third-party digital wallets to be able to use its tap-to-pay technology. The company said it “developed and provides a mechanism that protects user security while enabling third-party developers to offer alternate payment applications.”

“Apple is simply not a monopolist,” the company wrote in its filing. The DOJ, it said, measured its share in the smartphone market by revenue rather than unit sales. It also put smartphones and “performance smartphone” in separate categories, which “does not correspond to economic reality.” Apple accused the DOJ of narrowly focusing on Apple “without fairly considering the major manufacturers like Samsung and Google that [the company] contends with in the United States, not to mention the various lower-cost manufacturers — especially from China — that Apple confronts globally.”

As 9to5Mac notes, the lawsuit is now heading to discovery phase, where both sides will now have to gather evidence to support their case.
