Previous Web access authentication systems often use either the Web or the Mobile channel individually to confirm the claimed identity of the remote user. This paper proposes a new protocol using multifactor authentication system that is both secure and highly usable. It uses a novel approach based on Transaction Identification Code and SMS to enforce extra(More)
The next section entails a discussion of some related efforts which is followed by the RISM system design in section III. Section IV describes protocol and the simulation results are given in the section V. The last section presents some concluding remarks. II. RELATED WORK Reputation-based systems are a new paradigm and are being used for enhancing(More)
Stub This paper talks about a new approach to recognize named entities for Indian languages. Phonetic matching technique is used to match the strings of different languages on the basis of their similar sounding property. We have tested our system with a comparable corpus of English and Hindi language data. This approach is language independent and requires(More)
— A Mobile Adhoc Network (MANET) is a cooperative engagement of a collection of mobile nodes without any centralized access point. The underlying concept of coordination among nodes in a cooperative MANET has induced in them a vulnerability to attacks due to issues like dynamically changing network topology, cooperative algorithms and lack of centralized(More)
A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. Wireless sensor networks gather data from places where it is difficult for(More)
— Automatic parallelization of a sequential code is about finding parallel segments in the code and executing these segments parallely by sending them to different computers in a grid. Basically, parallel segments in the code can be found by doing block level analysis, instruction level analysis or function level analysis. Block is any continuous part of(More)
This paper addresses the problem of fast retrieval of data from XML documents by providing a labeling schema that can easily handle simple as well as complex XPATH queries and also provide for updates without the need for the entire document being re-indexed in the RDBMS. We introduce a new labeling schema called the "Z-Label" for efficiently processing(More)
