    Multilevel access control for video database by Jin-bo XIONG, Zhi-qiang YAO, Jian-feng MA, Qi LI

    Published 2012-08-01
    “…In regards to the critical issues of classification protecting sensitive information of the data stored in video database,a multilevel access control model for the video database was proposed.A series of algorithms was designed and developed in the model where a method of distinguishing user identity and an algorithm to ensure good identity strength were presented.The result of them was then used as the input to user's security level membership function.The user's security level membership degree was subsequently acquired from the result of this function,and it is then,together with the security level membership degree of video data,used as input to the comparison function of security level membership degree in authorization rule.As a result,the multilevel access control can be implemented neatly through combining the result of the comparison function with time element.Compared with the existing access control models,the most outstanding characteristics of the proposed model are realizations of dynamic authorization and video data classification protection.…”

    Published 2014-01-01
    “…Packet loss will make severe errors due to the corruption of related video data. For most video streams, because the predictive coding structures are employed, the transmission errors in one frame will not only cause decoding failure of itself at the receiver side, but also propagate to its subsequent frames along the motion prediction path, which will bring a significant degradation of end-to-end video quality. …”
