Camera software developed by Sony to protect against biometric theft, manipulation

0

sony has developed camera software which it claims can sign images to provide evidence against tampering or manipulation. Image manipulation, and in particular face morphing, is considered a threat to the integrity of biometric systems.

The in-camera anti-tampering photo technology is aimed at professional users, and the software is initially released on the Alpha 7 IV camera. The functionality is planned to be extended to other models in the future.

The tool is used by the camera processor to cryptographically sign each frame as it is captured. Any pixel modification, tampering, or attempted tampering will be detected by the client’s certificate server, which then voids the image signature, according to Sony.

“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 tampering across multiple industries. commented Yasuo Baba, Director of Digital Imaging and European Product Marketing at Sony. “Although appropriate adaptations for each industry must be made, the digital signature is multilingual and can be used internationally, allowing organizations around the world to streamline mandatory image signing with Sony technology.”

The new tamper-proof signature mode uses cryptography to ensure images are created and transmitted securely, Sony says.

The technology is suitable for protecting images used for issuing passports and verifying identity documents, but also in media, medicine and law enforcement. It could also be used in construction and insurance to inspect and record damage.

Photos used in passports must meet standards set by ICAO to enable biometric processing of travellers, and some surveys have suggested that ensuring the integrity of these images remains a challenge. Manipulated images in the form of deepfakes, meanwhile, are a growing concern.
