Abstract

This work aims at creation of a secure voting system. This will be accessible to all voters who have a valid smart card registered officially with age above 18 years. This system provides the following facilities of Voting at any remote terminal, verification of the end users choice and an authentic and secure voting implementation. The voters, without any insider privileges, can cast unlimited votes without being detected by any mechanisms within the voting terminal software is also the major threat yet to be addressed. A basic solution is the voting systems having a voter verifiable secure audit trail, where a computerized voting system might print a paper ballot that can be read and verified by the voter with authenticity being ensured and the confidentiality being maintained. In such a system, the correctness burden on the voting terminal’s code is significantly less as voters can verify a physical object that describes their vote and are allowed to vote in terminal only after their identity is proved by series of authentication procedures.

Abstract

The aim of this paper is to provide an introduction towards the architectural design of a bi-fold authenticated agent-monitored transaction model. The focus is primarily on implementation in ATM systems which provide the following facilities of withdrawing currency at any remote terminal, verification of the end users identity using Personal Identification Number and an authentic One-Time-Session-Dependent Key generation and validation through the mobile. This system requires building up of an third party agent which would establish a secure session to the bank application with the terminal only after a series of authentication mechanism without compromising the privacy of any individual. The customers, without any insider privileges, can withdraw currency without being detected by any mechanisms of theft of card and eaves dropping of the Password from the card holders within the terminal software are also a major threat yet to be addressed. A basic solution is the terminals having bi-fold authentication mechanisms where mobile dependent one time session dependent key is being generated with authenticity being ensured and the confidentiality being maintained. In such a system, the correctness burden on the terminal's code is significantly less as the customers have been given the chance to authorize themselves from their hand-held devices and are allowed to withdraw currency in terminal only after their identity is proved by a series of authentication procedures. In this paper along with the bi-fold authentication implementation, architectural design of the agent which is being introduced is also briefed.

Abstract

A server, which is to keep track of heavy document traffic, is unable to filter the documents that are most relevant and updated for continuous text search queries. This paper focuses on handling continuous text extraction sustaining high document traffic. The main objective is to retrieve recent updated documents that are most relevant to the query by applying sliding window technique. Our solution indexes the streamed documents in the main memory with structure based on the principles of inverted file, and processes document arrival and expiration events with incremental threshold-based method. It also ensures elimination of duplicate document retrieval using unsupervised duplicate detection. The documents are ranked based on user feedback and given higher priority for retrieval.
