Sony’s tamper-proof technology adds cryptographic signature to in-camera photos

Sony counterfeit-proof technology

Sony has announced the availability of its in-camera tamper-proof photo technology that cryptographically signs photos at the point of capture, allowing photographers to detect if the image is tampered with or altered in the future.

The technology, which is aimed at corporate business uses, uses digital signatures that are processed by the camera at the point of capture and allow photographers to detect if any alterations have been made to an image and, the company says, protect them from use. fraudulent.

The company says this technology was developed in response to what it calls “widespread problems” with unauthorized editing and “misconduct” around digital photo data. The tamper-proof technology is based on standard cryptography and, when activated, the camera’s processor immediately processes images with a unique signature.

“After this, any pixel modification, alteration or possible forgery will cancel the image signature, as the client’s own certificate server will detect image tampering during the scan,” says Sony.

The company adds that this new forgery-proof signing method ensures the secure creation and transmission of images. Sony argues that the technology is particularly useful for passport and identity verification, but goes further by tackling image manipulation in the fields of media, medicine and law enforcement. He adds that the insurance and construction sectors could also use it as a safe way to inspect and record damage.

“Sony’s mission is to empower business solutions with cutting-edge imaging technology and our in-camera digital signature is a true game changer in combating image manipulation and counterfeiting across multiple industries,” Yasuo Baba, director of digital imaging and European product marketing at Sony. , he says.

“While appropriate adaptations are required for each industry, the digital signature is multilingual and can be used internationally, allowing organizations around the world to streamline mandatory image signing with Sony technology.”

Sony joined the Coalition for Content Provenance and Authenticity (C2PA) earlier this year. C2PA is the content authenticity standards body that addresses the prevalence of misleading information online, which has similar goals to what Sony is positioning as a response with its new technology. That said, Sony’s announcement doesn’t mention C2PA.

At launch, this technology is only available on the Sony Alpha 7 IV camera and is subject to receipt of a license to enable Signature Mode from Sony, the price of which was not disclosed and is only available to commercial users. Sony says it has plans to expand support for this new crypto firm to other cameras, but did not provide details or a timeline for such a rollout.
