Abstract
For securing content accessed from storage device, the storage device is associated with a licensee identifier. The licensee identifier is provided as input to an algorithm that generates, based on the identifier, a determinate set of instructions for a computer, for example, source code in a coding language, compiled binary code, or pseudo code that is capable of being translated into source code. The code, once compiled to machine-usable form, can be executed by a processor to perform a permutation operation that is unique to the licensee identifier. The output of the permutation operation can be used for protecting data provided by the storage device.
