Big Data Oriented Fuzzy Based Continuous Reputation Systems for VANET

Multi-faceted and Multi-algorithmic Framework (MFMA) for Finger Knuckle Biometrics

Privacy can be a key aspect of the user experience with computers, online systems, and new technologies. Knowing what to consider about users and their views of computer systems can only improve privacy mechanism. Human Computer Interaction (HCI) is the sub field of Computer Science that studies how people interact with and through computational technologies. In this paper, a three-level model-based approach is provided for the end user privacy in the human computer interaction as the end user’s privacy in the area of HCI is emerging as critical design element for interacting systems in areas as diverse as e-commerce, health care, office work, personal communications etc. The data privacy of end user as well as the resource access privacy is needed to be considered. As of now, no proper solution exists for all types of interface users which is a major privacy issue. Hence, to provide the end users, their personal data protection as well as the resource access security, this paper focuses on analyzing and developing the theory of technological acceptance related to user privacy

Three Level Based Security for Improvised User Privacy in Human Computer Interaction

Vehicular Networks facilitate communication among vehicles to notify and exchange road-related information and thereby, ensure road safety. In VANETs', the network infrastructure provides a facility to generate the messages. But all such messages need not be reliable. Therefore, in order to build reliability on the message, the vehicle in which the message was generated can be evaluated based on a reputation score that it has earned during its prior transmissions. This paper aims to design and analyse a reputation system for VANET's which aids the receiving vehicle to decide the reliability on the message based on the score that has been earned by the transmitting vehicle.

Towards modelling a trusted and secured centralised reputation system for VANET's

Preserving the privacy of the vehicle on the move is an important challenge in VANET's. Vehicles can be loaded with Pseudonyms that can be changed frequently in specific intervals to prevent tracking of the vehicle by a third party. Yet, this scheme supports only a short travel from home and moreover the RSUs' do not play a major role. Therefore, this paper proposes a scheme of implementing a security mechanism using Blind Signature, where the Road Side Units in collaboration with the Trusted Authority generates the keys to be transmitted to the vehicles. These short lived keys are used to send and receive messages on the roads. The paper considers two ideal places where the vehicle stops for some long time, one being the traffic signal and the other is a parking lot. The key update time for the two scenarios using Blind signature is compared with the earlier scheme where the vehicle changes its Pseudonym based on the neighbouring vehicle. The proposed approach has been evaluated using simulations in Ns-2.

Pseudonyms Based Blind Signature Approach for an Improved Secured Communication at Social Spots in VANETs

Wireless sensor networks are of a large number of low cost resource constrained sensor nodes. Each node has to sense certain phenomena and forward its data towards a central node, which is also called the base station. The range of applications include basic data reading like temperature to a wide variety of applications including agriculture. A large amount of work has happened into the design and analysis of the sensor devices. These sensor can handle high level of data exchange without reduction in performance. The data to be exchanged are of vital importance and need to be handled with high level of confidentiality. Though there are security algorithms that offers mechanisms for data confidentiality there is a rising need for improvement for better level of security. The hackers can be from node level to process level. This paper outlines the different security issues in wireless sensor network and provides scope for improvement. {\textcopyright} 2012 IEEE.
