ABSTRACT:
A system and method to securely create, distribute, install and execute selected features of software on wireless devices combines three different types of licenses, a validation license, a digital rights management (DRM) license, and a feature license with a software application. Each of these three licenses work independent of each other, where the validation license helps prevent malicious code from executing on wireless devices, the DRM license prevents unauthorized copying of the software application and the feature license securely enables or disables specific features of the software application. The system also allows a wireless device to unwrap a DRM protected software application, to validate the software application, to enforce DRM usage rules and to execute selected features of the software application.
