JPEG has issued a Call for Proposals on Privacy & Security to provide new protection tools to JPEG family of standards

JPEG Privacy & Security – JPEG Privacy & Security is a work item (ISO/IEC 19566-4) aiming at developing a standard for providing technical solutions which can ensure privacy, maintaining data integrity, and protecting intellectual property rights (IPR). JPEG Privacy & Security is exploring ways on how to design and implement the necessary features without significantly impacting coding performance while ensuring scalability, interoperability, and forward & backward compatibility with current JPEG standard frameworks.

Since the JPEG committee intends to interact closely with actors in this domain, public workshops on JPEG Privacy & Security were organised in previous JPEG meetings. The first workshop was organized on October 13, 2015 during the JPEG meeting in Brussels, Belgium. The second workshop was organized on February 23, 2016 during the JPEG meeting in La Jolla, CA, USA. Following the great success of these workshops, a third and final workshop was organized on October 18, 2016 during the JPEG meeting in Chengdu, China. These workshops targeted on understanding industry, user, and policy needs in terms of technology and supported functionalities. The proceedings of these workshops are published on the Privacy and Security page of JPEG website at www.jpeg.org under Systems section.

The JPEG Committee released a Call for Proposals that invites contributions on adding new capabilities for protection and authenticity features for the JPEG family of standards. Interested parties and content providers are encouraged to participate in this standardization activity and submit proposals. The deadline for an expression of interest and submissions of proposals has been set to October 6th, 2017, as detailed in the Call for Proposals. The Call for Proposals on JPEG Privacy & Security is publicly available on the JPEG website.

High Throughput JPEG 2000 – The JPEG committee is working towards the creation of a new Part 15 to the JPEG 2000 suite of standards, known as High Throughput JPEG 2000 (HTJ2K). The goal of this project is to identify and standardize an alternate block coding algorithm that can be used as a drop-in replacement for the algorithm defined in JPEG 2000 Part-1. Based on existing evidence, it is believed that large increases in encoding and decoding throughput (e.g., 10X or beyond) should be possible on modern software platforms, subject to small sacrifices in coding efficiency. An important focus of this activity is inter-operability with existing systems and content repositories. In order to ensure this, the alternate block coding algorithm that will be the subject of this new Part of the standard should support mathematically lossless transcoding between HTJ2K and JPEG 2000 Part-1 codestreams at the code-block level. A draft Call for Proposals (CfP) on HTJ2K has been issued for public comment, and is available on the JPEG web-site.

JPEG PLENO – The responses to the JPEG Pleno Call for Proposals on Light Field Coding will be evaluated at the July JPEG meeting in Torino. The quality assessment procedure for this highly challenging type of large volume data has been defined during JPEG 75th meetings. In addition to light fields, JPEG Pleno is also addressing point cloud and holographic data. Currently, the committee is undertaking in-depth studies to prepare standardization efforts on coding technologies for these image data types, encompassing the collection of use cases and requirements, but also investigations towards accurate and appropriate quality assessment procedures for associated representation and coding technologies. JPEG committee is probing for input from the involved industrial and academic communities.

JPEG XS – This project aims at the standardization of a visually lossless low-latency lightweight compression scheme that can be used as a mezzanine codec for the broadcast industry and Pro-AV markets. Targeted use cases are professional video links, IP transport, Ethernet transport, real-time video storage, video memory buffers, and omnidirectional video capture and rendering. After a Call for Proposal and the assessment of the submitted technologies, a test model for the upcoming JPEG XS standard was created and results of core experiments have been reviewed during the 75th JPEG meeting in Sydney. More core experiments are on their way to further improve the final standard: JPEG committee therefore invites interested parties – in particular coding experts, codec providers, system integrators and potential users of the foreseen solutions – to contribute to the further specification process.

Next generation Image Formats – The JPEG Committee is exploring a new activity, which aims to develop an image compression format that demonstrates higher compression efficiency at equivalent subjective quality of currently available formats, and that supports features for both low-end and high-end use cases.  On the low end, the new format addresses image-rich user interfaces and web pages over bandwidth-constrained connections. On the high end, it targets efficient compression for high-quality images, including high bit depth, wide color gamut and high dynamic range imagery.

"JPEG is committed to accommodate reliable and flexible security tools for JPEG file formats without compromising legacy usage of our standards" said Prof. Touradj Ebrahimi, the Convener of the JPEG committee.

About JPEG

The Joint Photographic Experts Group (JPEG) is a Working Group of ISO/IEC, the International Organisation for Standardization / International Electrotechnical Commission, (ISO/IEC JTC 1/SC 29/WG 1) and of the International Telecommunication Union (ITU-T SG16), responsible for the popular JBIG, JPEG, JPEG 2000, JPEG XR, JPSearch and more recently, the JPEG XT, JPEG XS, JPEG Systems and JPEG PLENO families of imaging standards.

The JPEG group meets nominally three times a year, in Europe, North America and Asia. The latest 75th meeting was held on March 26-31, 2017, in Sydney, Australia. The next (76th) JPEG Meeting will be held on July 15-21, 2017, in Turin, Italy.

More information about JPEG and its work is available at jpeg.org or by contacting or of the JPEG Communication Subgroup.
