MTSA provides a systematic framework for multimedia information
security, however, designing the corresponding rule
and strategy for MTSA is still a challenging task. The decentralized
data acquisition process in MTSA offers opportunities
to exploit the distributed nature of the network. We provide a
novel distributed privacy paradigm for MTSA, in which the
authority, cost, and encryption are obtained in a decentralized
manner. Figure 4 illustrates the corresponding general rule
and strategy.
