The invention relates to a secure, tamper- and forgery-proof peripheral for the storage of authenticated, dated computer data with an evidential value. The invention is based on an optionally-rewritable, fully-integrated storage peripheral which is functionally protected by an electronic system which onl y authorises the addition of data in the unused free space and prohibits the deletion, alteration or overwriting of pre-recorded data. At the end of each file-write operation, the date, which is provided by a non-modifiable intern al clock that is calibrated only at the time of production, is associated therewith. Each device comprises a unique integrated secret internal digital identifier which is associated with a unique public identifier and said identifiers are used to personalise the device and render same unreproducibl e. The aforementioned association can be verified using several third methods which never divulge the secret internal identifier. According to the invention, a physical and electronic peripheral protection system activates, incorporates and protects the assembly of above-mentioned internal elements and destroys the unique internal identifiers in the event of an attempted intrusion, compromise, corruption or internal analysis. For said purpose, th e authenticity of the equipment assembly is invalidated and, consequently, so too are the stored data which nonetheless remain readable. The inventive device is particularly suitable for the private storage and archiving of computer data having an authentic, juridical and/or legal weight of evidence in respect of official authorities. Moreover, said device uses no heavy cryptography methods.
