摘要： The present invention provides methods and apparatus to detect and reliably record the physical history of a product including effects due to one or more of the following: 1) product use 2) handling 3) tampering and 4) environment of the product (as changes in the environment, such as excessive temperatures, humidity, or shocks, can result in degradation to a product). The apparatus includes a “smart card”, or, more generally, “smart token”, in combination with one or more sensors which record the external influences on the product and/or the environment and records those changes in an encrypted form. This information can then be verified by any individual who is equipped with a (possibly public) decryption key, but capability to modify this information, depending on the application, is restricted to those with access to the encrypting key. Furthermore, the apparatus contains authentication information which can be reliably verified, in particular to confirm that the apparatus is attached to the product it supposed to be attached to.
