Abstract
Methods and systems for device notarization and verification are provided. In one implementation, various integrity values are concatenated to generate a concatenated value that is used to generate a transaction data signature (TDS). In one implementation, the concatenated value is a concatenation of a device value, an application value, an application encryption (AE) module value, and an authentication generation (AG) module value. The TDS or notarization code is generated by applying the concatenated value to the AG module. In one implementation, subsequent use of the application on the device involves generation of a new TDS, which is compared against the notarization code to determine whether use of the application on the device is authorized. In one implementation, the AE module and the AG module are seeded with a seed value which includes a device value, an application value, a user specific value, and a pseudo random number.
