Abstract
An application registration data generator, on a per application basis, generates application registration data that contains at least application identification data, such as, the name of a software application or a pathname to a software application, and stored unique application verification data that is based on executable file data. A data access determinator determines whether a calling application should be allowed access to the limited access based data by, for example, computing a hash value of the executable file and checking whether this hash value matches the corresponding stored unique application verification data. If there is a match, the application is granted access to the user's cryptographic parameters, privilege data, or other limited access based data on a per application basis.
