NEXT-LIFE: Securing 3D content for virtual worlds – NEXT-LIFE

The NEXT-LIFE project concerns the security of 3D content for applications involving the visualization, manipulation, purchase/sale/exchange of 3D content in virtual environments. The security of these 3D contents is envisaged along two axes, namely watermarking and encryption.

While 3D watermarking consists in embedding a message in the 3D content, in a robust and invisible way, 3D encryption consists in degrading the visual appearance of the 3D content if the user does not have the decryption key. In both cases, standard 3D content formats must be respected. It is then necessary to evaluate the quality of a watermarked 3D object and the visual security of an encrypted 3D object.

This project is directly in line with the H.17 axis "Global Security, Resilience and Crisis Management, Cybersecurity", in particular for the "Multimedia Security" aspects, and contributes to the fight against cybercrime, in the sense that attacks, frauds and illegal copies of these 3D contents are emerging in these new universes, opening up possibilities for multiple crimes (frauds, embezzlement, identity theft, frauds...)

The NEXT-LIFE project proposes solutions to secure the 3D content itself, either as a complement or as an alternative to existing rights and security management systems. Moreover, NEXT-LIFE is interested in securing not only 3D meshes but also the data associated with them such as textures and materials in the context of virtual environments.
