System for integrity validation of authorization data using cryptographic hashes

Abstract:

A system provides integrity validation of authorization codes using cryptographic hashes. In particular, the system may use various types of input data to generate a randomized hash value which may be associated with a user, device, or set of data (e.g., an authorization code). For instance, the input data may include historical log data, location and/or geolocation data, contextual data, salt values, or the like. In this way, the system may generate a hash value that is randomized while adding meaning that is unique to the user, device, or data with which the randomized hash value is associated.
