San Diego, CA—Sony Electronics delivered firmware updates for the Alpha 1 (Ver. 2.00), Alpha 7S III (Ver. 3.00), Alpha 7 IV (Ver. 3.00) and, after April 2024, the Alpha 9 III (Ver.2.00). They include Sony firmware C2PA compliancy updates, including the Camera Authenticity Solution. It provides a proprietary in-camera digital signature and C2PA (Coalition for Content Provenance and Authenticity) format support.

Together, these tools will make it possible for news agencies to ensure the authenticity of images. They will also contribute to industry efforts to protect creators and society from fake imagery.

Additionally, the more than 45 firmware updates include requested features to improve everyday camera use. Included here are shooting functions and post-shooting workflow as well as advanced movie features, like breathing compensation. They also include new remote-control capabilities, new features for professional applications and expanded access to cloud services applications.

“There is nothing more core to our mission than listening to the voices of the photographers, videographers and filmmakers who shoot with Sony Alpha cameras. We know this community has been asking for these updates. We’re happy to deliver. Each of these updates are designed to promote ease of use for our creators and allow them to maximize the strengths of their cameras,” said Yang Cheng, vice president, Imaging Solutions, Sony Electronics Inc.

“We’re especially pleased to deliver C2PA compliancy with this update. This compliancy paired with our unique digital signature technology, allows us to offer the most secure and comprehensive solution to protect professional photographers, news agencies and society from manipulated imagery.”

Sony Firmware C2PA Compliancy Updates

Last year, Sony announced its commitment to developing technology in its cameras to aid in the fight against manipulated imagery and AI-generated fakes. Further, a critical part of the solution is making more Sony cameras C2PA compliant. C2PA is a joint development foundation project. Sony is a steering committee member. C2PA aims to develop an end-to-end open technical standard to provide publishers, creators as well as consumers with opt-in, flexible ways to understand the authenticity and provenance of different media.

The C2PA is a standards-setting body that will develop technical specifications on content provenance and authentication by certifying the source and history of media content. Moreover, with Sony’s Camera Authenticity Solution firmware update, the authenticity information embedded on images from Alpha 1, Alpha 9 III, Alpha 7S III and Alpha 7 IV are maintained from capture through publication. This means professional photographers can preserve their digital signature from the camera. They can also track the editing history throughout revisions.

Digital Birth Certificate

Another critical component of the solution is Sony’s in-camera digital signature technology that signs images in real-time. This new feature certifies the authenticity of an image at the point of capture. What’s more, it creates a “digital birth certificate” that is retained throughout revisions. The signature contains metadata like 3D-depth information captured through the proprietary technology in the Sony-developed image sensor. This depth information shows if the image captured was of an actual 3D object, versus a photograph of an image or video. Thus, it provides an extra level of protection and more assurance of the content’s authenticity.

Sony’s solution also helps protect the authenticity of content by including an Image Validation Site. The site verifies the image even after edits were made by C2PA-compliant editing software. This service confirms the photo was taken by a specific camera and that the object of the photo is 3D. Sony will initially offer this service to select news media agencies.

Shooting and Playback Updates

The firmware updates also comprise more than 10 new features, as well as improvements to existing features. Sony designed these updates to improve a user’s overall shooting experience. A few highlights of the firmware update functions include:

  • Relay Playback: Enables seamless sequential playback from one memory card slot to another on the Alpha 1, Alpha 7S III and Alpha 9 III.
  • Playback Filter Condition: Lets users categorize image playback based on select criteria, including date, folder and file format, on the Alpha 1 and 7S III.
