US Patent 9552278 Configurable code fingerprint

A method, computer program product, and system performing a method that include a processor defining a code fingerprint by obtaining parameters describing at least one of an event type or an event. The code fingerprint includes a first sequence. The processor loads the code fingerprint into a register accessible to the processor. Concurrent with executing a program, the processor obtains the code fingerprint from the register and identifies the code fingerprint in the program by comparing a second sequence in the program to the first sequence. Based on identifying the code fingerprint in the program, the processor alerts a runtime environment where the program is executing.
