ABSTRACT:
A digital contents distribution system that generates first execution verify logic, second execution verify logic and execution verify logic conversion software. The first execution verify logic and second execution verify logic each carry out the verification and execution control of contents, and the first execution verify logic is linked with the contents at first. The execution verify logic conversion software includes execution verify logic converter for replacing the first execution verify logic with the second execution verify logic to relink the latter with the contents. A user terminal is provided with the contents linked with the first execution verify logic, and the execution verify logic conversion software.
