Service and P2P based secure media sharing in mobile commerce environments

Abstract

Service technology is slowly evolving to be a promising technology for developing applications in open, loosely coupled and distributed computing environments, e.g., in mobile commerce (m-commerce). Services technology can shield the heterogeneous platforms and is suitable for m-commerce applications. Peer-to-Peer (P2P) technology becomes more and more popular for mobile commerce applications. For secure media distribution in m-commerce applications, the security and P2P rights management become more and more urgent. New schemas and architectures for secure P2P based m-commerce applications, which are expected to function automatically or semi-automatically, are expected. In this paper, a secure media service system is presented, which can trace illegal distributors in m-commerce applications. In this scheme, the decryption operation and fingerprint embedding operation are combined together, which avoids the leakage of clear media content in mobile transfer. Additionally, these operations are implemented by the peer, which makes the scheme compliant with existing Peer-to-Peer Digital Rights Management (DRM) systems and very proper for secure media distribution in m-commerce applications. The architectures and modes of secure media distribution in m-commerce environment are presented and discussed.

An Empirical Study of the Factors Affecting Mobile Shopping in Taiwan

“…As long as mobile technology facility is equipped, commerce service will be available for any person at any time (Xi & Shiguo, 2011). Computing is expanding from stationary desktop PC environments to locations like cars, shopping malls and entertainment areas.…”

End-to-middle-to-end solution for IMS media plane security

“…This paper proposes a complete solution that copes with the functional requirements for including a trusted network-operated resource function in a secured media path. As possible future media protection research areas, advanced digital rights management techniques shall be considered to protect unauthorized media distribution even from those users allowed to access the media flows [14].…”
