Direct reading protecting process for e.g. music information, involves generating digital signature from files created by digitization of characteristics of physical unit e.g. paper, and associating signatures with information

摘要

The process involves selecting a physical unit e.g. paper, and digitizing characteristics of the physical unit, by taking into account chaotic, complex, unique and stable structure of the physical unit, for creating files. Digital signatures are generated from the files by applying several algorithms. The signatures are associated with sensitive digital information in direct or indirect manner. Independent claims are also included for the following: (A) a data carrier medium having sensitive information protected from direct reading by implementing a direct reading protecting process (B) a process for reading of protected sensitive information stored on a data carrier medium (C) a device for implementing a direct reading protecting process.
