Title: PROTECTION OF PROGRAMS, STREAMING MEDIA AND OTHER DATA FLOWS
Abstract:
A method is provided to generate a protected program from an original program such that the protected program is less vulnerable than the original program to unauthorised use when installed on a device. The method includes: receiving, at a processor, an original program, wherein the original program takes an input data flow and generates an output data flow. The processor then transforms the original program into a white-box implementation of the original program including encoded functional blocks, and then transforms the white-box implementation of the original program into a node-locked program by further encoding the encoded functional blocks of the program with device specific parameters to provide node- encoded functional blocks, wherein the node-locked program is for use on and is node-locked to the device.
