But despite their remarkable advantages, consumers are still reluctant in their use, especially for online transactions and reason being the increasing credit card fraud rate. A number of security models have been proposed and deployed for secure online transactions but the sharing of sensitive credit card data over the Internet has made online transactions vulnerable to threats. In this paper, we discuss and analyze the current developments in online authentication procedures including biometrics, one-time-password systems and use of mobile device and Public Switched Telephone Network for cardholder authentication. Then we propose a complete new framework for both onsite and online (Internet shopping) credit card transactions. This framework is more secure, robust, enhances user privacy and does not involve the deployment of special hardware systems at the customer's site.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"86 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116307271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Usually security algorithms have to be embedded in a variety of applications like e-banking, online shopping, mails etc. So they should be fast as well as secure in different environments. In this paper, we do security v/s performance analysis of two algorithms Two fish and AES. First, we will discuss security issues of both algorithms by considering their safety factor. Then we study encryption speed of both algorithms by encrypting different type of data (text, image, audio) and analyze their performance in terms of throughput of every algorithm on different size of RAMs. The results show the relationship between performance of algorithms and size of RAM and type of data.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"218 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126115692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional image segmentation techniques using region growing requires initial seeds selection, which increases computational cost & execution time. To overcome this problem, a single seeded region growing technique for image segmentation is proposed, which starts from the center pixel of the image as the initial seed. It grows region according to the grow formula and selects the next seed from connected pixel of the region. We use intensity based similarity index for the grow formula and Otsu's Adaptive thresholding is used to calculate the stopping criteria for the grow formula. We apply the proposed method to the Berkley segmentation database images and discuss results based on Liu's F-factor that shows efficient segmentation.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125224029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biometric identification systems can be used for gaining access to systems and verification purpose. However, biometrics such as iris, fingerprint, etc. are vulnerable to early decay and decomposition. On the other hand, dental x rays remain invariant over time and resist early decomposition, fire, etc. Hence they can be used for human identification purpose. In this paper, a novel approach to feature extraction of dental x-ray radiograph is proposed based on the shape and texture of extracted tooth from the radiograph and thereafter matching is done by finding mean square error between the query and database images.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127993066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control design is attained by introducing the dead-zone nonlinearity and using it in the controller design with back stepping technique. A dead-zone inverse is developed to compensate the dead-zone effect in nonlinear systems. In this scheme, Chebyshev Neural Network (CNN) is used to approximate the unknown nonlinear functions and also used to compensate the dead-zone nonlinearity. New weight updates laws are derived to guarantee uniform ultimate boundedness (UUB) for all signals in closed loop system.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125136955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper analyzes the performance of OTFT made of several organic semi conducting and insulating materials and further discusses their applications. Analysis of previous research work demonstrates that the mobility in OTFT decreases when the product of semi conducting film thickness and gate capacitance per unit area increases. The decrease is specified by a power law function with parameters for several organic semiconductors. OTFT characteristics have undergone spectacular improvements during the last few years. This paper explores the effect of variation of channel length from 40 nm to 20 nm on drain current for pentacene bottom contact structure. Variations in these quantities maps to variations in the electrical behaviour of devices. It has been found that drain current increases due to decrease in length of organic thin film conducting channel. It reviews recent progress in parameter properties for device designs and applications related to OTFTs. The performance of OTFTs is evaluated in terms of mobility, on/off current ratio, threshold voltage and sub threshold slope. This paper thoroughly discusses the overall performance and applications of OTFTs in various fields.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115727155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
