Sony has announced the discovery of in-camera fake photo technology that allows photographers to secretly sign images at the point of capture.
Focused on corporate business uses, the technology uses digital signatures created by the camera at the point of capture, allowing photographers to recognize that an image has been altered and, according to the company, prevent them. The use of fraud.
The company says the technology was developed in response to unauthorized editing and “distortion” around digital photo data. The forgery-proof technology is based on standard cryptography and when activated, images are immediately processed with a unique signature by the camera processor.
“Following this, any pixel modification, tampering or forgery will invalidate the image signature, as the image manipulation is detected by the client’s own certificate server during inspection,” says Sony.
The company added that this new pseudo-authentication signature method ensures secure image creation and transmission. Sony argues that the technology is particularly useful for passport and ID verification, but will do more to combat image fraud in the media, medical and law enforcement sectors. He adds that the insurance and construction sectors can use it as a reliable way to investigate and record damage.
“It’s Sony’s mission to empower business solutions with cutting-edge imaging technology, and our camera digital signature is a real game changer in the fight against image fraud and counterfeiting across a range of industries,” said Yasuo Baba, director of digital imaging and European product marketing at Sony. He says.
“While appropriate customization is required for each industry, the digital signature is multilingual and can be used globally, allowing organizations around the world to facilitate mandatory image signing with Sony technology.”
Sony joined the Coalition for Content Provenance and Authenticity (C2PA) earlier this year. C2PA is part of a set of standards focused on content integrity that is addressing the spread of misleading information online, which has similar goals to what Sony has set the new technology as an answer to. Sony’s announcement did not mention anything about C2PA.
At launch, this technology will be available only on the Sony Alpha 7 IV camera and will require a license to enable Sony’s signature mode. The price is undisclosed and it will only be available to commercial users. Sony says it plans to expand support for this new cryptographic signature to other cameras, but did not provide details or a timeline for the said planned release.
