On the Design of a Secure Multimedia Archive

Abstract. Broadcasting companies have started to move towards a tapeless pro-duction process by storing their multimedia (MM) content in a digital archive [1, 2]. Such a digital archive enables a much more efficient production process, and facilitates the disclosure to the general public, allowing broadcasting companies to extend their business model; this comprises extra services such as subscrip-tions for libraries to access content, pay-per-view for the general public to access its archive, etc. This paper describes our work within the scope of a multidisci-plinary project with as goal to design and implement a digital multimedia content archive. We have studied the security aspects of an archive that can be integrated into the production process, allowing broadcasters to share and exchange multi-media content easily, and can be disclosed to semi- and non-professional users. The main result of this study is the identification of security techniques required for such an archive, how they should be embedded into the architecture, and the assessment of their applicability and maturity, based on an extensive threat analysis.
