The JPEG-blockchain framework for GLAM services

This paper proposes a JPEG-blockchain framework for trusted media transaction. The new distributed and tamperproof framework intends to aid an emerging JPEG Privacy and Security standard. The blockchain network records any media transaction with necessary information related to intellectual property rights, access control rules and content signature. The content signature, generated by compressed sensed samples or low-resolution, low bit-rate compression is used to verify the image integrity and authenticity. We propose that every blockchian record, linked to a unique transaction hash, is encapsulated within the metadata contained in the JPEG box structure. As an example use case we have chosen the GLAM (Galleries, Libraries, Archives and Museums) sector due to its emerging need. This paper presents the proof of the concept and reports preliminary infrastructural development.
