Annotation:
The project is focused on security of distributed information systems. When certain level of users' anonymity is requred, security mechanisms must be based on different source of data. Trust or reputation becomes crucial information for security of IS. This approach based on experience inevitably implies number of problems that become subjects of this project: possibility of attacks, exploitation of faked identities, effective reations to attacks, use of indirect evidence, search for interesting patterns in stored evidence. The problems named are profound for the whole research area covering decentrelized distributed information systems.
