SVIP-Enhanced Security Mechanism for SIP Based VoIP Systems and Its Issues

Abstract

Abstract.As the SIP based VoIP system is entirely based on IP network, the vulnerabilities in it affects the VoIP system. This may result in degrading of quality of service in three aspects such as confidentiality, integrity and availability. This paper diagnose the security issues such as registration hijacking, session teardown, message tampering, IP spoofed flooding, disguised proxy and Spam over Internet Telephony (SPIT) and as well as the enhancements to improve the security mechanism to overcome the issues and to provide the quality of service to the legitimate users.

A novel framework to prevent privacy breach in cloud data storage area service

“…An intelligent model based hybrid approach to preserve user digital content, pervasive and ubiquitous computing environment privacy preservation carried out, and a generic approach to molt the assurance of secrecy in maintain cloud digital data.
