A method of protecting an executable program from reverse engineering and/or tampering. The method includes receiving a copy of the executable program together with a debug database, the database storing the locations of functional blocks within the executable program. A protection code is inserted into the executable program so as to overwrite at least part of a functional block of the executable program. Subsequent execution of the functional block causes the protection code to be executed. The protection code, when executed, performs an operation and executes a copy of the overwritten part of the functional block. |
