3rd JPEG Workshop on Media Blockchain Announcement (Geneva)
February 22, 2019

JPEG calls for industry/academic participation to its 3rd workshop on media blockchain. This free public workshop will be held in Geneva on Wednesday the 20th of March 2019 in conjunction with the 83rd ISO/IEC JTC1/SC29/WG1 (JPEG) Meeting.


Fake news, copyright violation, media forensics, privacy and security are emerging challenges for digital media. JPEG has determined that blockchain technology has great potential as a technology component to address these challenges in transparent and trustable media transactions. However, blockchain needs to be integrated closely with a widely adopted standard to ensure broad interoperability of protected images. JPEG calls for industry participation to help define use cases and requirements that will drive the standardization process.

Presentations from the 1st (Vancouver) and 2nd (Lisbon) workshop are available here:
