Security and Privacy in Distributed Information Management

In our paper will be presented some advances in procedures used for encryption and division of secret data, as well as modern approaches for management of divided information. Computer techniques for secret information sharing aim to secure information against disclosure to unauthorized persons. The paper will describe algorithms allowing for visual information division and sharing on the basis of personal features. The development of computer techniques for classified information sharing should also be useful in the process of shared information distribution and management. For this purpose there will be presented a new approach for information management based on cognitive information systems.
