The inside scoop on watermarking and content authentication

Nov 06, 2023 - technologyreview.com
President Biden's executive order on AI emphasizes the use of watermarking and content authentication technologies to identify AI-generated content and combat misinformation. The government plans to promote these tools, with the Department of Commerce establishing guidelines and federal agencies using these techniques in the future. The Coalition for Content Provenance and Authenticity (C2PA) is expected to play a significant role in this, with its open-source protocol that uses cryptography to encode details about the origins of a piece of content.

However, the executive order does not require industry players or government agencies to use this technology. There are also concerns about the reliability of watermarking technologies, with research indicating they are prone to tampering, triggering false positives and negatives. Despite these challenges, the C2PA is in regular contact with federal agencies and hopes the White House's action will increase awareness and adoption of its content credentials.

Key takeaways:

  • President Biden's executive order on AI emphasizes on watermarking and content authentication technologies to determine whether content was made by a machine or a human.
  • The government plans to promote these tools, establish guidelines for them, and use them in the future to fight AI-generated misinformation.
  • The Coalition for Content Provenance and Authenticity (C2PA) is a key player in content authentication, using an open-source protocol that relies on cryptography to encode details about the origins of a piece of content.
  • Despite the potential of watermarking and content authentication, researchers warn that these techniques are vulnerable to tampering and can trigger false positives and negatives, making them unreliable.
