Abstract: A method and system to generate fine granular integrity to huge volumes of data in real time at a very low computational cost. The invention proposes a scalable system that can receive different digital data from multiple sources and generates integrity streams associated to the original data. This invention provides full guarantees for data integrity: order of data logged cannot be altered and content cannot be modified neither added nor deleted without detection.

Abstract: 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.

Abstract: Methods and systems that enable reliable audits of a number of predetermined trust requirements for games by electronic means, either on-site or remote, are disclosed. A system including a gaming module to which the players interact with a security module and an audit module capable of several degrees of dispersion and/or grouping performs provision by the gaming module to the security module of digital information containing significant events occurred during the games, generation by the security module of a protected record for each of the cited significant events, storage by the security module of every protected record, generating a file of protected records, and access by the audit module to the file of protected records, independent from the games operator, to verify the correct development of the games.
