A system (100) for verifying authenticity of at least part of an execution environment (158) for executing a computer program module (150). The system includes a processor (120) and a storage (140) for storing the computer program module and the execution environment. The computer program module is operative to cause the processor to process digital input data (152) in dependence on a plurality of predetermined digital parameters. The system includes means (200) for deriving at least part of one of the plurality of predetermined digital parameters from the at least part of the execution environment.
