DRM support added to JPEG
On June 22-26, 2015, a regular meeting of the Committee of the Joint Committee of Photographic Experts (JPEG Committee) was held. It made several important decisions , including it was decided to begin standardization of the lightweight JPEG XS format for transferring uncompressed images and video over the Network where there is an important low transmission delay and not so important traffic volume.
In addition, the JPEG committee reported on “finding solutions that can ensure privacy and security when publishing photos on social networks, stock databases of photos, etc.”
To achieve this goal, it is planned to implement the “JPEG Privacy & Security” function within the existing JPEG image format.
““ JPEG Privacy & Security ”will provide new functionality for JPEG encoded images, including ensuring confidentiality, preserving the image intact and protecting intellectual property rights, while maintaining backward compatibility with existing JPEG solutions and ensuring compatibility with future changes to the standard . An open seminar on “JPEG Privacy & Security” was organized to collect opinions from stakeholders, which will be held on October 13, 2015 at the next meeting of the JPEG committee in Brussels, ”the press release said.

Apparently, the JPEG committee is really going to implement in the format support for full DRM. Fragments of their documents, which happened to be in open access , give an idea of ​​what it will be. Among the functions, “access control to certain images according to the specified rules” is indicated, while “the rules are established either by the service provider or the owner of the image”.
The rules determine the conditions of access according to various criteria: 1) user: specific person, group, coordinates, characteristics; 2) context: date and time, number of views, action (view, download, ...), etc .; 3) image: quality, geolocation, author, date, semantic information, etc .; 4) action: reading, updating, deleting, etc.
It would seem that this is, if not a full-fledged DRM system?
Some experts suggest that the JPEG Committee’s ideas are based on this scientific work by Pavel Korshunov and his colleagues, where the idea of ​​encrypting (scrambling) JPEG is discussed to securely publish photos on the Internet and to protect against unauthorized observation.
