Authorship and content integrity are the two most basic rights that academic authors want to preserve in the educational field. In order to preserve these author rights a special adapted rights management platform - ARMS - was developed. This platform is oriented towards the educational domain and we must to highlight a web services interface that enables the integration with a generic educational Academic Management System platform of the educational institution, necessary to verify the user eligibility in this domain before license issuance. To guarantee content and rights protection, cryptographic techniques and mechanisms are applied in such a way where content, rights, protection keys and related metadata are packaged in special containers obeying the MPEG-21 standard. The resulting objects described here, obey a special structure that can be only used by users in the educational domain to whom the respective license was issued. These “neutral” resulting objects can then be easily transmissible in open communications channels in a way that enables their management in order to achieve a controlled access and usage. They are the main data transport bodies that enable content protection and rights transmission among participants in the content protection lifecycle.
