Abstract

The integrity of a dynamic data object that comprises one or more dynamic data items is ensured by storing the dynamic data object and dynamic authorization data in a memory. The dynamic authorization data may, for example, be a count of how many failed attempts to gain authorization have previously been made, and this is modified at least whenever another failed attempt is made. Whenever the dynamic data object or the dynamic authorization data is changed, its corresponding hash value is recomputed and stored into the memory. The dynamic data object is considered authentic only if newly-generated values of the two hash signatures match those that were previously stored into the memory. Changes to the dynamic data object are permitted only after the user has executed passed an authorization procedure.
