  • Use of a digital signature obtained from at least one structural characteristic of a material element to protect the direct reading of sensitive data and method for reading this protected data
    Patent number: 8943325
    Abstract: The invention is related to the use of one or several digital signatures obtained from at least one structural characteristic of a material element that has a complex, chaotic, unique and stable structure, to protect the direct reading of sensitive data, a media of such protected data and a method for reading this protected data.

  • Method for recognition and tracking of fibrous media and applications of such a method, particularly in the computer field
    Patent number: 7680306
    Abstract: The invention relates to a method for acceptance of a candidate fibrous medium comprising the following steps: a candidate digital signature is generated from a structural characteristic extracted from a reference zone of the fibrous medium, the said digital signature representing the unique, complex, chaotic structure of the reference zone, practically invariable with time; the candidate digital signature is compared with at least one authentic digital signature previously recorded on a digital data medium so as to issue a positive or negative decision about acceptance of the candidate fibrous medium; characterized in that the comparison uses a statistical method to calculate a similarity index between the candidate digital characteristic and the authentic digital signature, and to compare this similarity index with a given acceptance threshold, so as to enable issuing a positive acceptance decision if the candidate digital signature does not exactly correspond to the authentic digital signature with whi
