Researchers at Princeton and Stanford have developed Perceptual Ad Blocker , an ad - blocker able to detect ads by scanning a page 's source code rather than reading its HTML markup or tags . Although the technology can be used to show ads or pop - ups urging users to whitelist the ads , the proof - of - concept identifies how web browsers ' architecture affects users and ad - blockers , according to ben Narayanan , one of Perceptual Ad Blocker 's developers . The proof - of - concept is currently in tests as a browser extension that enables ads to be displayed without identifying text , although its full ad - blocking capabilities may be added later .
Researchers at Princeton and Stanford have developed Perceptual Ad Blocker, an ad-blocker able to detect ads by scanning a page's source code rather than reading its HTML markup or tags. Although the technology can be circumvented to show ads or pop-ups urging users to whitelist the site, the proof-of-concept identifies how web browsers' architecture favours users and ad-blockers, according to Arvind Narayanan, one of Perceptual Ad Blocker's creators. The proof-of-concept is currently in tests as a Chrome extension that enables ads to be displayed without identifying text, although its full ad-blocking capabilities may be introduced later.
