In many applications relevant to MPEG standardization, an identification of individual users or a description of users may be desirable. Currently, a user description in the context of MPEG-V is under investigation. A more focused and all-embracing effort related to user identification might be required. This identification of users may be useful for content adaptation and for exploitation of user preferences. Obviously, such a user identification bears some risks related to privacy. The Requirements subgroup kindly encouraged organizations to provide input on user identification/description to the 95th meeting. No input was received.
