Authorship and content integrity are the most basic rights that academic authors want to preserve in the educational field. In order to preserve these author rights a special adapted DRM platform, ARMS, was developed. This platform is oriented to the educational domain and we must to highlight the web services interface with a generic educational Academic Management System platform of the educational institution, established in order to verify the user eligibility in this domain before issuance of the license. To guarantee content and rights protection, cryptographic techniques and mechanisms are applied in a fashion where content, rights, protection keys and related metadata are packaged in special containers obeying the MPEG-21 standard. The resulting objects describe here, obeys a special structure where protected objects may only be used by the user of the educational domain to whom the respective license was issued embedded in one of these objects. These neutral resulting objects can then be easily transmissible in open communications channels in a way that enable 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 content protection lifecycle.
