It works by examining how websites load, scrutinizing HTTP communications with web servers and the JavaScript and HTML instructions out of which websites are constructed. To make that approach effective, Brave must have an effective system for blocking conventional ads and ad trackers.ĪdGraph isn't built into Brave, but the company has plans to do so, it said in a blog post Friday. The company wants to restart the online ad industry with ads that are personalized but that don't leak your private data out of the browser itself. And Europe's General Data Protection Regulation ( GDPR) is making life harder for companies to harvest your personal data.īrave AdGraph analyzes websites to try to identify what elements are ads or behavior trackers.īrave, co-founded by former Mozilla leader Brendan Eich, blocks web ads and the behavior-tracking software that often accompany them. But online ads - which can be annoying and intrusive, slow down computers and phones, and even deliver malware - are in trouble.Ībout 615 million people use ad blockers on computers and mobile devices, according to PageFair, a company that seeks to help website publishers evade the blockers to reclaim revenue that otherwise would be lost.
Brave's AdGraph approach instead uses artificial intelligence, trained on real-world websites, so it can spot ads and trackers even before a human has reported them.Īd blocking is a major threat to internet services whose growth has largely been fueled by free services supported by ads. In addition, AdGraph is able to detect a significant number of ads and tracker which are missed by popular crowdsourced filter lists."Īd-blocking browser extensions like Adblock Plus today typically use manually maintained filter lists such as Easylist to determine what's an ad and what's not. "We found that AdGraph replicates the behavior of popular crowdsourced filter lists with an 97.7 percent accuracy. "We can train supervised machine learning models to automatically block ads and trackers," researchers from Brave and four universities said in a research paper. Brave has developed AI technology called AdGraph that outperforms conventional ad-blocking technology, the browser startup said Friday.
