Cloud computing is the emerging technology in the data services platform. The networked systems that connected through the systematic nature for the cloud interpretation from the client level to the cloud level usage defines with the ranked search methodology called as Multi-keyword Ranked SEarch (MRSE), the security level in the multicast ranked search remains unhold ...
Owing to recent technological advancements in wireless sensor and communication technologies, WSN has become a prominent research topic tapping the potential use of it to a wide range of applications. A large quantity of miniscule sensor nodes collaborating and communicating through a wireless medium, collect and propagate data finally to a base station or sink ...
In present years, there has been momentous progress in multimedia technologies. Transmission of multimedia data such as audio, video and pictures above the Internet is now-a-days extremely common. Though internet is extremely insecure channel and this poses a number of protection issues. To accomplish confidentiality and protection of multimedia data above an insecure channel like ...
Need for digital video communication is increasing day-by-day. In the very near future itself, video may become the dominant type of traffic over the Internet. A secure scheme of digital video communication is presented in this paper using a combination of both cryptography and steganography. Multiple encryptions at the transmitter side followed by data hiding ...
So far, majority of applications and websites mainly use traditional login method based on username and password. These identity authentication systems acquire two steps that users must execute. Firstly, users must complete registration. Secondly, they must enter correct username and password to login, only these two steps will spend seven or eight minutes. Moreover, the ...
Use of security tools are increased over recent years as a result of increased number of malicious events. To detect possible anomalous events security administrator makes use of intrusion detection system. Earlier intrusion detection systems have higher FPR and lower detection rate. This motivates many researchers for designing different models for detection. Designing host based ...
Cognitive radio is the most promising and reliable emerging technology which can utilize the scarce radio spectrum efficiently. In this technology the secondary (unlicensed) users need to find idle channels by spectrum sensing for their transmission. Spectrum sensing may be single user or cooperative. However cooperative spectrum sensing is considered better. In this paper, simple ...
In this paper, the authors describe determination of GPS receiver position using Bancroft algorithm. The position is determined by obtaining pseudo ranges from seven different GPS satellites. The measured ranges do not represent the true ranges as the signal coming from a GPS satellite will be affected by various errors like ephemeris error; propagation error ...
Technology at present needs faster and easier means of controlling equipment with few numbers of components. One of such equipment is the Direct Current (DC) motor, whose speed is directly proportional to the supply voltage. Using this established relationship between the speed and the supply voltage, this paper investigates the effects of different loads and ...
Early aspects focus on the problem domain, representing the goals and constraints of users, customers and other constituencies affected by a software intensive system. However, analysis of early aspects is hard because stakeholders are often vague about the concepts involved and may use different vocabularies to express their concerns. In that the goal modeling fits ...
