Methods, Systems and Computer Program Products for Determining Usage Rights for Digital Content Based on Characterizing Information Thereof and Related Devices

摘要

A method for controlling unauthorized use of digital content includes identifying digital content for validation. Characterizing information is generated that designates the identified digital content, and usage rights for the identified digital content are determined based on the characterizing information, for example, based on a comparison of the characterizing information that designates the identified digital content to a plurality of characterizing information. Usage of the identified digital content may also be controlled based on the determined usage rights. Related systems, methods, devices, and computer program products are discussed.
