Software digital rights management is a pressing need for the software development industry which remains, as no practical solutions have been acclamaimed succesful by the industry. We introduce a novel software-protection method, fully implemented with todays technologies, that provides traitor tracing and license enforcement and requires no additional hardware nor inter-connectivity. Our work benefits from the use of secure triggers, a cryptographic primitive that is secure assuming the existence of an ind-cpa secure block cipher. Using our framework, developers may insert license checks and fingerprints, and obfuscate the code using secure triggers. As a result, this rises the cost that software analysis tools have detect and modify protection mechanisms. Thus rising the complexity of cracking this system.
