An anti-tampering method applicable to data associated to products or documents comprises at least the following steps: a) generating a security secret key-code, in the form of an optically readable code, on a surface or into a multilayer chemical structure for hot/cold transfer applications; b) optically reading the key-code in order to decode it by software means and, through the same software means using encryption algorithms, generating a security secret lock-code in the form of an optically readable code, said lock-code being univocally and exclusively linked to the key-code and comprising the information about said products or documents in the form of encrypted data. The invention also comprises an anti-tampering device applicable to data associated to products or documents to be used in connection with the anti-tampering method, said device comprising a label that holds at least said key-code, said label being structured with a first part realized as an holographic structure hot/cold stamped on a receiving adhesive second part of said label, wherein said first part and second part of said label comprise a structure adapted to contain said codes and to be read by optical devices. The invention also comprises a kit for reading said data on said anti-tampering device. |
