🎙️New on #TheBraveTechnologist podcast: Jack Pertschuk, former Principal Engineer at Pinecone, explains what vector databases are and why they matter for AI and search apps. Listen to his full chat with Luke Mulks 👉 https://lnkd.in/epzk6D8g

Can online services preserve users' privacy while verifying their age? A proposed solution, called zero-knowledge proofs, has potential but also has limits. With zero-knowledge proofs (ZKPs), the user can prove they meet verification requirements without sharing personal information. For example, a user can show that they're above 21 without revealing their exact birthdate or other details. However, zero-knowledge proof systems have several issues that prevent it from fully protecting users' privacy including: - Possible information leaks - Centralization of authority - Exclusion of people without digital IDs Today's blog post by our research team explains the limits of ZKPs and how we can overcome them.

Thank you to our users for working so hard to let friends and family know about us. It's helping us continue to reach new growth milestones. 📈 The Brave browser reached 101.69 million monthly active users in October. The fastest growing platform is Linux, which now has over 1 million monthly active users. Brave Search's usage, meanwhile, has grown to over 1.73 billion queries per month. Nearly 10% of those queries are coming from people who don't use our browser.

How is Claynosaurz making digital ownership fun, accessible, and frictionless? CEO Andrew Pelekis explains the process on the #TheBraveTechnologist. Check out the full episode, hosted by Luke Mulks, here: https://lnkd.in/eNtz89pf

Another performance boost is coming to Brave! 🦁 We’ve completed the next stage of improving the memory usage of the browser’s native adblock engine. The cosmetic filters in our ad blocker have been moved to flatbuffers, a more compact and efficient type of storage. This under-the-hood change saves ~12 MB of memory on all platforms by default (Android, iOS and desktop), and even more when additional lists are enabled! By blocking unwanted ads and trackers, Brave already reduces how much memory sites use. This performance work ensures that these built-in protections are as lightweight as possible, too. These changes are live in Brave Beta on all platforms now and will come to the release build by December.

⚠️ Instructions hidden in a website's HTML can trick an AI browser into giving up your sensitive information. Today, we're revealing details on a prompt injection flaw we found in Opera Neon: https://lnkd.in/ezziDvxU How this attack works: 1) Attacker embeds instructions in hidden HTML elements or other non-rendered markup. 2) The user asks Opera Neon's AI a question. The AI extracts and processes the entire HTML structure including the instructions. 3) The browser obeys the instructions. In our demo attack in the video below, embedded instructions force Opera Neon to find and share the user’s email address. This same approach could be used to steal more sensitive info. For example, you could find a Neon user's credit card details if they're signed into that card's account. Last week we reported similar prompt injection flaws we discovered in AI browsers Perplexity Comet and Fellou: https://lnkd.in/efBxHjkd In each case, we disclosed vulnerabilities to affected browser vendors before publishing our findings so that they could fix these issues. Indirect prompt injection is a serious unsolved security problem facing all AI browsers that can act on the user's behalf. We're proud to have raised awareness of the issue through our research. But more must be done to secure AI browsing.

Brave and academic peers have developed SURE, a system that lets users privately report issues with AI models. The system then repairs these models while protecting the confidentiality of the model, data, and the repairing knowledge. Their paper was accepted by the 39th Annual Conference on Neural Information Processing Systems, a top-tier conference for ML and AI. It will be presented by Brave senior researcher Ali Shahin Shamsabadi at Hilton Mexico City Reforma on December 5.

The newly launched multiplayer game ARC Raiders has taken over the new tab page in the Brave browser today! 🎮 The secret is out: Brave Ads are a powerful way to reach Brave's over 100 million users.
