1. the read method of a protected sensitive data, it is characterized in that, by carrying out digital processing to read to the protected sensitive data of digital form, this digital processing uses the digital signature extracted from material cell as reading key, this material cell is selected from fibrous material, plastics, metal, leather, timber, glass, all or part of of mineral or crystal structure material, described digital signature is from the complexity of this material cell of reflection, unordered, unique and at least one architectural feature of this material cell of rock-steady structure obtains, described digital signature self is reflected and keeps representing the unique of this material cell and rock-steady structure stable, random and complex characteristics,Wherein, by the one or more architectural features using one or more sensor to detect described material cell, carry out digitized processing thereafter and be attended by obtaining described digital signature according to the coding of one or more algorithms of described architectural feature,Wherein, reading process uses one or more decipherment algorithm, using described digital signature as decruption key.
