The project objective is to develop an architectural framework for dokspot 2.0 including a high level project plan for implementation. In addition to the general features of dokspot 2.0 (described above under 2. Background) a security concept (or at least security requirements in areas where a security concept cannot be formulated within the project) for dokspot 2.0 should be formulated. A specific focus should be placed on the integrity protection (tamper protection) of textual, audio and video data.
