9,374,226, "Protection method and system for distributing digital files whether new, second-hand, for rental, exchange or transfer," assigned to Carrillo De La Fuente, Miguel Angel (ES).
A method for generating a virtual recursive secure container and for generating a virtual secure container of relationship of rights along with a system that distributes copyrighted digital content, respecting the legal framework for intellectual property when distributed electronically, either on the Internet or any other digital medium, and offering consumers their rights as buyers of digital content. The logical components, `Master Avatar` and `User Avatar`, which reside in the users' digital devices, create the virtual framework for relating rights of author and consumer. By providing each avatar with a key to decrypt the data of digital content distributed through the system, the virtual link for relating the rights of author and consumer is created. Digital content is only distributed in a virtual secure container if the author or a licensed medium previously published that content in the system and authorized its distribution in scenarios allowed by the system.
