Google has released an improved version of its SynthID AI content detector, now available globally with a login requirement and daily usage quota, supporting detection of watermarks from Google, OpenAI, and Apple.
Google launched a public website that lets anyone verify whether images, videos, or audio were AI-generated using its SynthID watermarking technology, expanding access beyond journalists and researchers. The tool is supported by partners including OpenAI, Nvidia, and Kakao, and handles verification requests at a rate of 1 million per day.
Security researcher David Buchanan (retr0id) demonstrates a C2PA spec footgun allowing arbitrary byte-range "exclusions" in signed files, showing how timestamped Content Credentials can be forged to "hack time" — e.g. backdating winning lottery numbers — undermining C2PA as a trust anchor for image provenance.
A user notes that recent AI-generated videos have become virtually indistinguishable from real footage, citing the AI character 'JEANPHIL' that fooled most commenters, and asks how society will verify authenticity as AI realism keeps improving.
