Texas HB4437 mandates the Department of Information Resources to implement a digital watermarking system and a hashmark sharing database for tracking.

HB4437 requires the Texas Department of Information Resources to implement a digital watermarking system for images posted on state websites. This system will embed data provenance into each image and generate a hash for each image, which is recorded in a cryptographic hash database. The digital watermarking system must be tamper-evident and verifiable by the public. The bill also mandates the development of a hashmark sharing database for hashes related to child sexual abuse material, accessible to state agencies, private sector entities, and law enforcement.
