TSAR: Secure Transfer OF High Resolution Art Images


The EROS (European Research Open System) database hosted at the Centre de Recherche et de Restauration des Musées de France (C2RMF) is one of the largest database in the world of Cultural Heritage that is widely recognized for its high resolution images. The French research project TSAR (Transfert Sécurisé d'images d'Art haute Resolution) aims to give the possibility to open this huge amount of art images in a secure and efficient way. For this purpose, we use a mixture of techniques to assure the security of the data involving cryptography and watermarking techniques as well as multi-resolution compression scheme together with a region-level representation. These algorithms are especially optimized for high resolution art images. In particular, this means that the quality of the transmitted images have to be not reduced, implying the use of lossless coding techniques. In this paper we present an overall scheme that provides an efficient, consistent solution for secure data browsing, viewing and transmitting, adoptable by any Cultural Heritage institution.
