New Digital Signature Technology Being Tested by World’s Largest Camera Manufacturers
Nikon, Sony, and Canon have teamed up to develop an innovative technology to protect the work of photojournalists from sophisticated AI-generated fake images. This new “tamper-resistant” digital signature technology aims to provide increased security for companies and news organizations by authenticating genuine photos and differentiating them from AI-generated visuals.
The new anti-tamper technology is set to be integrated into new or recent cameras by 2024, as reported by Nikkei Asia. It will include vital information such as date, time, location, and the photographer’s identity, adhering to a “global standard” adopted by the three camera giants.
Additionally, the companies will introduce a free web-based “Verify” service to authenticate images. For those with a digital signature, the Verify website will display embedded credentials, while images without credentials will be indicated as “No Credentials.”
Sony plans to incorporate the technology into three “professional-grade” mirrorless SLR cameras through firmware updates in the spring, according to Nikkei.
Sony will provide its own authentication server to verify the integrity of digital signatures. The company reportedly tested this solution with the Associated Press in October, and future cameras equipped with digital signature capabilities are anticipated.
Canon is set to offer similar authentication services in 2024, and is developing a solution to incorporate robust digital signatures into video content, collaborating with news agencies and universities since 2019.
As generative AI services continue to produce deepfake content and manipulated images, various countermeasures are being developed. Google has introduced a tool that embeds “invisible” watermarks in AI-generated images, and Intel has devised a solution that assesses image authenticity by analyzing changes in skin color, while Adobe is working with Leica to support Content Credentials, a signature-based security feature.
