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.

System and method for secure file access of derivative works

A virtual local file system for managing file access, such as read, write and execute, of files on local media is disclosed. An access manager, executable by the host operating system, is stored on each host device. The access manager interacts with the local file system to control file access permissions and how processes of the host operating system execute, view or modify files accessible to the local file system. The access manager may also dynamically control file access to files on the host operating system using a file attributes repository, which may be stored locally or remotely from the host device. Exemplary attributes for defining permission to access a file include but not are limited to, specific users, a time of day, a number of copies of a file, an allowed process, an IP address range, and a MAC address.
