In this paper three layers memory structure is adopted to address the challenge which we refer to as three layer conceptual network (TLCN). This highly efficient network simulates the human brain by episodic memory, discourse memory and ground memory. An extended case structure framework is used to represent the knowledge. The knowledge database is constructed by the collection of target system information and utterances. This knowledge is updated after every dialog conversation. A Recurrent Neural Network classifier is also introduced for classifying the knowledge for the target system. This system prototype is based on doctor-patients dialogs. 78% disease classification accuracy is observed by this system prototype. Disease identification accuracy is depending on number of disease and number of utterances. This performance evaluation is also discussed in details.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124862110","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}

In a server client based communication system such as Yahoo Messenger, AIM, passwords of clients are hashed by MD5 and passed to the server for authentication. This type of transmission is always a subject of interception by the hackers. These hashed passwords are passed through the Internet as a data packet. TCP header is a most common part of the data packet. In a TCP header there are six reserved bits which remains always unused. In this paper we propose a new approach to enhance the security of hashed passwords by using the six reserved bits of a TCP header. Here we encrypt the hashed password by a random key using simple mathematical function. The information needed to decrypt the encrypted hashed password is carried by the six bits of TCP header.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124872121","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 proposed gSVMT achieves to discover data subregions with principal discriminant knowledge through a recursive SVM-supervised data partitioning procedure. For each subregion, an individual SVM is allocated to extract the subregion knowledge. A set of such SVMs are aggregated in a specific order, resulting in a globally reliable decision rule to predict new coming samples. Experiments on a synthetic Gaussian data set and 13 benchmark machine learning data sets, have highlighted the usability of the gSVMT on its competitive classification capability. In particular, the proposed gSVMT is found to have better generalization performance than SVM classifiers for data sets with high sparseness and/or class-imbalance. Its performance has been further demonstrated with the successful real application on a face membership authentication system.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127456858","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}

Mobility data based on real human behaviors may give us the opportunity to improve wireless and Mobile services for users in many ways. At present, several mobility models are proposed based on the analysis of real traces . In this paper, we investigate the feasibility of next state prediction using sequences of previously observed state and analyze the efficiency of MARKOV MODEL . The scenario concerns servicing wireless devices by wireless access point in the Dartmouth college campus over some period of time. The performance of the method has been verified for prediction accuracy.

Large-scale sensor networks impose energy and communication constraints, thus it is difficult to collect data from each individual sensor node and process it at the sink to detect faulty sensors. The proposed approach saves energy and improves network lifetime by detecting data faults locally in cluster head and therefore reducing the number of transmissions required to convey relevant information to the sink. This paper presents a novel approach for detecting sensors which produce faulty data in a distributed way as well as identifying the type of data faults using trust concepts to gain a high degree of confidence. We validate our method with simulations results.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131951294","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}

Becoming more and more similar to PCs and laptops, they will also begin to face the same security problems especially in terms of network security. In this paper, we provide an overview of security issues for smartphones and give a brief introduction of the network stack architecture of Windows Mobile 5.0 platform in order to motivate and plan for efficient penetration tests against Windows Mobile 5.0 powered smartphones. Furthermore, a number of attacks have been done against different layers of the network stack and a list of supporting penetration tools are provided for interested practitioners. Detailed results are provided from the penetration tests performed which should be very useful for security vendors, researchers and OS vendors to give more attention to security architectures and development of security software (e.g. firewalls, antivirus) for the mobile operating systems. In a whole, robustness and stability will be assessed for the mobile OSs used by the smartphones throughout the paper.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115883049","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}
