With increasing popularity of cloud computing, the data owners are motivated to outsource their sensitive data to cloud servers for flexibility and reduced cost in data management. However, privacy is a big concern for outsourcing data to the cloud. The data owners typically encrypt documents before outsourcing for privacy-preserving. As the volume of data is increasing at a dramatic rate, it is essential...
Modern communications networks have many challenges and opportunities for improvement. Data integrity and its Security over a communication network is one of such challenges. Digital Watermarking have been proposed as a new method to impose ownership verification and protect data from tempering by illegitimate user. To make digital watermarking more effective digital signature or message authentication...
IEEE 802.16 WiMAX provides high data rate but limited coverage area and 3G is well established network with low data rate as comparison to WiMAX network. So if we will combine both WiMAX and 3G network then it provides ubiquitous high speed data access as well as attract wider user base. In this paper we have taken component which is used in interworking architecture, security consideration, authentication...
Authentication of multimedia content is required to proof the data integrity and establish the identity of the content creator. In this paper, we propose a source authentication and tamper detection scheme under the framework of H.264/AVC. To overcome the burden of sending authentication information separately, a noble reversible data embedding method is proposed. In this scheme, content based digital...
