Facebook’s secret “Project Ghostbusters” project involved intercepting and decrypting Snapchat users’ network traffic to gain insights. It’s important to note the ethical implications surrounding data collection and prioritize transparency. The project underscores the lengths major tech companies go to outperform the competition.

Google has agreed to delete billions of records collected from Incognito mode browsing and restrict its user tracking practices as part of a settlement in a class-action lawsuit.

Google has delayed its plans to phase out third-party cookies in Chrome, citing the need for more time due to industry and regulatory pressure. Despite assurances that it wouldn't backtrack on its timeline, Google did not announce a new date, but mentioned it would not meet its target of deprecating cookies during the second half of Q4 this year.

Thus far, ZK is used for efficient signature verification, storage proofs, proving transactions, and bridging – all parts of the modern modular stack. Going forward, ZK could solve open problems around avoiding redundant compute and preserving privacy.

Sentry recently removed non-essential cookies and trackers from its public websites. It identified cookies using Chrome's developer console and specialized scanners while using Content-Security-Policy (CSP) reporting for a comprehensive overview. To maintain a cookieless environment, Sentry implemented CSP with strict rules and continuous monitoring using custom scripts and a cookie scanner.

Apple's new Apple Intelligence system will use Private Cloud Compute to ensure any data processed on its cloud servers is protected in a transparent and verifiable way. Many of Apple's generative AI models can run entirely on a device powered by an A17+ or M-series chip. When a bigger model is required to fulfill a generative AI request, Apple Intelligence only sends relevant data to complete the task to special Apple silicon servers. Customer data will not be saved for future server access or used to further train models. The server code used for Private Cloud Compute will be publicly accessible.

Adobe is updating its terms of service on June 18 to clarify that it won't train AI on customers' work, addressing user concerns about vague language. The company has never used customers' content for AI training or taken ownership. It aims better to explain its policies in response to community criticism.

Tools for Humanity, the builder of Worldcoin, has hired former execs from Google, X, and Apple to improve the privacy, security, and identity management aspects of its project.

Google Chrome and Microsoft Edge gives websites owned by Google exclusive access to a special API that allows monitoring of system resources and detailed processor information.

Google announced it will no longer phase out third-party cookies in its Chrome browser, citing the need for more comprehensive solutions that balance user privacy and industry requirements. This decision comes after multiple delays and feedback from advertisers and regulators indicating that the transition was more complex than anticipated. Instead, Google will implement a new system that allows users to make informed choices about their web browsing privacy settings.

This shift raises questions about user response, with ad-tech experts predicting the end of cookies will now be driven by consumer preferences. Google's Privacy Sandbox, intended to replace cookies, has faced scrutiny and mixed results. The details of Google's user prompts and opt-out mechanisms remain unclear, but their impact on third-party cookies could be substantial.

Google is still figuring out its cookie opt-in model, with few details available so far. Google's Privacy Sandbox product manager, Alex Cone, has clarified that the deprecation of third-party cookies and the Privacy Sandbox are not inherently linked. The most pressing question is whether the new opt-in model will resemble Apple's ATT framework, which essentially rendered Apple's mobile ad ID obsolete for targeted advertising.

Meta's Privacy Aware Infrastructure (PAI) is a large-scale initiative designed to enforce purpose limitation. PAI's key component, Policy Zones, provides a comprehensive mechanism for encapsulating, evaluating, and propagating privacy constraints for data in transit and at rest. Its integration across various Meta systems, including function-based and batch-processing systems, makes sure that data is only used for its intended purpose.

A leaked video suggests that Chainalysis may have found ways to trace Monero (XMR) transactions and identify associated IP addresses, raising concerns about the privacy claims of the cryptocurrency. While Monero's team has not yet commented, some see the firm's efforts as potentially helping to improve the blockchain's security.

An Australian investigation into Meta's privacy practices has resulted in the company's admission that it has been scraping public posts, photos, and comments from both Facebook and Instagram for the past 17 years. This data was used to train its generative AI model.
