Dynamic and Cyclic Properties of Soilsks and replacement attacks even in case of restricting the amount of encryption to 1% – 2% of the data. The low encryption effort required is due to the exploitation of the interdependencies among resolution layers in the JBIG hierarchical progressive coding mode.

Dynamic and Cyclic Properties of Soilse the capabilities of unauthorized users to perform hidden data removal using solely a signal processing approach based on optimal estimation as well as consider reversibility on the side of authorized users who have the knowledge of key used for the message hiding.

Functioning of the Soil System, users, we have to assure, that the recorded video-material is only available to a subset of authorized users under exactly previously defined circumstances. In this paper we propose a CCTV video surveillance system providing privacy in a distributed way using threshold multi-party computation. Due

Functioning of the Soil System,ty provider. Access to this information is managed using so-called Attribute Release Policies (ARPs). In this paper, we first analyze various shortcomings of existing ARP implementations; then, we demonstrate that the eXtensible Access Control Markup Language (XACML) is very suitable for the task. W
