Cryptographic Techniques in Advanced Information Management

The paper presents new solutions in the area of application cryptographic protocols for strategic or personal information protection and management. Computer techniques for classified information protection and distribution will be described in the context of application for security purposes personal or biometric information. Such techniques may also support the management processes of confidential data, and distribution of parts of shared information in large management structures. Development of presented algorithms will enable the reconstruction of secured information exclusively by the confidants with access to the secret, and parts of the information shared - i.e. by the authorized users of shared information. At the same time the proposed information division techniques will effectively secure data against unauthorized access to encrypted information.
