Touradj Ebrahimi is a Professor at EPFL heading its Multimedia Signal Processing Group and the Convenor of JPEG standardization Committee. Prof. Ebrahimi has been the recipient of various distinctions and awards, such as the IEEE and Swiss national ASE award, the SNF-PROFILE grant for advanced researchers, Four ISO-Certificates for key contributions to MPEG-4 and JPEG 2000, and the best paper award of IEEE Trans. on Consumer Electronics. Prof. Ebrahimi has initiated more than two dozen National, European and International cooperation projects with leading companies and research institutes around the world. His research interests include still, moving, and 3D image processing and coding, visual information security (rights protection, watermarking, authentication, data integrity, steganography), new media, and human-computer interfaces (smart vision, brain-computer interface).

Jaime Delgado is a Professor at the Department of Computer Architecture at the Polytechnic University of Catalonia (UPC-BarcelonaTECH). He was the director, and founder in 1999, of the Distributed Multimedia Applications Group (DMAG) until being integrated into the IMP (Information Modeling and Processing) research group in 2018. He is a Principal Investigator in various national and European research projects in the areas of Privacy and Security, Health Information and Genomics, Metadata, Digital Rights Management, and Distributed Applications. Since 1989, he has been co-editor of international standards and co-chairs of groups in ISO/IEC, EWOS, ETSI, ITU-T, etc. He has been the chair of the WG on Security of the EFMI (European Federation of Medical Computing) since 2017, evaluator and reviewer of the European Commission in different research programs, and adviser to various Spanish ministries and regional governments.

Nikolaos Fotos is a PhD candidate in the Computer Architecture Department at the Polytechnic University of Catalonia (UPC) in Barcelona, Spain. His research focuses on privacy in provenance information, with applications in media and healthcare. He received his diploma in Electrical and Computer Engineering from the National Technical University of Athens (NTUA) in 2018 and earned a Master’s degree in Cybersecurity from UPC in 2022. Nikolaos Fotos is also a contributor to the development of the JPEG Trust standard and its implementation.

The session will start with an introduction, overview and motivation of multimedia security & trust, and their wider application in our digital world. The intended outcome of this session includes

This session will focus on the details of the JPEG Trust standard and its framework, establishing that a media asset consists of the media asset content, media asset metadata, and a Trust Record. The framework intends to ensure the media asset’s integrity, authenticity, provenance and privacy - thus establishing the basis for trust in the media. The topics will follow the details of this standard, which include 1) JPEG Trust framework, 2) Media asset life cycle annotations, 3) Embedding and referencing, 4) Identification of assets and actors, 5) authentication and integrity and 6) Privacy and Protection.

This will be an interactive session where the participants will be engaged in a live coding session in which a tutorial leader implements some aspects of the standard, such as trust profile. The live coding will use a mix of pre-populated functions and GUI demonstrating the implementations of prototypical functionalities of the JPEG Trust standard.

Our aim is to achieve an improvised learning outcome through this participant-centred, problem-based demonstration session. Participants will be at the heart of this session and will also get the opportunity to develop their understanding through peer learning and informal conversations with the presenters on various topics relevant to the JPEG Trust standard.

This session will discuss various use cases identified over the last two years by the JPEG standard committee in discussion with several academics, industry partners and users. The session will broadly cover the following topics: 1) Misinformation and disinformation, 2) Forgery / Media forensics, 3) Media creation, & 4) Media modification.
