Abstract:

A data access manager is provided on a computing device to manage access to secure files stored in memory. The data access manager intercepts function calls from applications to the memory management unit and determines whether an application is allowed to access secure data stored in the memory of the computing device. When an initial request to map the data is received, the data access manager maps both secure data and clear data, obtaining pointers to both secure and clear data. When an application has permission to access the requested data, the data access manager returns the pointer to the clear data. When an application does not have permission to access the requested data, the data access manager returns the pointer to the secure data.

Abstract:

An access manager that detects a derivative work and automatically transfers digital access rights associated with an original work to the derivative work executes on a computing device. The access manager detects data to be written to a storage device and generates a new file signature for the data. The access manager compares the new file signature to existing file signatures, where the file signatures include piecewise signatures. When at least one of the piecewise signatures from the new file signature matches one of the piecewise signatures in the existing file signatures, the access manager determines that the new data to be written to the storage device is a derivative work generated from the existing file. The access rights associated with the existing file signature are copied to the new file such that the file access rights associated with the original work are passed on to the derivative work.
