<P>PROBLEM TO BE SOLVED: To provide a method of reading protected sensitive data. <P>SOLUTION: The method of reading protected sensitive data utilizes one or several random digital signatures extracted from a material element selected from all or some of fiber material, plastic, metal, leather, wood, composite material, glass, inorganic material, crystalline structure as a readout key, and is implemented by applying digital processing to the protected sensitive data in a digital form. The digital signatures are obtained from at least one structural characteristic of the material element that reflects a complex, chaotic, unique and stable structure of the material element, in order for the digital signatures to maintain random and complex characteristics representing unique and stable structures of the material element. <P>COPYRIGHT: (C)2012,JPO&INPIT |
