METHOD AND SYSTEM OF GENERATING IMMUTABLE AUDIT LOGS

摘要

This method and system uses means of cryptographic techniques reproducing the functionality of a continuous roll of paper. The audit logs can contain any kind of data information (text, voice, video, actions . . . ) and this invention provides full guarantees for data integrity: order of data logged can't be altered and content can't be modified neither added nor deleted without detection. Authenticity of the IAL is guaranteed by the use of digital signatures. Confidentiality is also guaranteed by encrypting the data information. By using PKI encryption the invention also guarantees that only authorized auditors will be able to check the integrity of the IAL and access to the data content.
