Multimedia Content Delivery System Based Advanced Watermarking Algorithm

Wireless multimedia communications have developed rapidly with increasing wireless access bandwidth and popular intelligent devices. Recent, a number of studies have been conducted to design tough and well organized schemes for delivering multimedia content over error-inclined wireless networks. In contrast, very few of those studies have concentrated on the security aspect of such transmission. There is have been increasing demands for the security of wireless multimedia Applications in recent years. Wireless networks when compared to traditional wired networks, are more likely prone to malicious attacks. Current security methods include physical layer and application layer security technologies independently and separately. Typically, physical layer information is dynamic in wireless networks, and application layer information is related to wireless multimedia content delivery. Both of them have significant impact on security performance.
