We point out that their scheme is vulnerable and susceptible to the attacks and can easily be cryptanalyzed. Their scheme provides only unilateral authentication (only client authentication) and there is no mutual authentication between user and remote system, so their scheme suscepts from the server spoofing attack. Their scheme also suffers from the impersonation attack and an adversary can easily impersonate a valid user. Furthermore, we describe that an adversary can login into the system by copying the data of stolen or lost smart card of a legitimate user. Moreover, we discuss that Wu and Chieu's scheme has poor reparability, which makes it infeasible to implement.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124852249","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 this framework each node calculates trust level of its neighboring nodes for route selection. Trust calculation process involves opinions of other nodes about the node whose trust level is to be determined. If a neighboring node has a trust level lower than a predefined threshold value, it is identified as malicious and it is not considered for route selection. The proposed security framework does not use any key distribution process and no changes are made in control packets of AODV. Simulation results show that the proposed framework improves performance of AODV by identifying and removing malicious nodes. Performance of the framework has been evaluated for three different types of malicious attacks (impersonation attack, colluding nodes attack and black hole attack).","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117227963","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 is due to the fact that it is not possible for a human agent to become fluent in all languages. In this paper, we propose a call routing system based on prosodic and phonetic features to improve the performance of automatic call routing systems. The main focus of this paper is to propose a feature set that efficiently improves the performance of the system without incorporating several sets of features. Our proposed approach for combining the prosodic and phonetic features achieves an accuracy rate of 98.36% for a binary language identification call routing system.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"2 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126033936","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}

However the robots are quite different in appearance and capabilities, but they accomplish the SAR task with a close synergy. Abilities of remotely detecting victims, using non-touch sensors, interactive user friendly control interface and following a planned trajectory to guide towards the victims are main facts of the prosperous SAR. Different parts of the synergetic system, robots; sensors, hardware, control interface, mapping and localization are introduced throughout the paper.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132411950","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 is due to the fact that accents vary widely, even within the same country or community. The reason may be attributed to the fuzziness between the boundaries of phoneme classes, a result of differences in a speaker's vocal tract and accent. In this paper, a new method of accent classification is proposed that is based on fuzzy Gaussian mixture models (FGMMs). The proposed method first uses a fuzzy clustering to fuzzily partition the data. In this way, fuzzy memberships to the cluster centres are determined by minimizing the distance between the cluster centres and feature vectors. Afterwards, a GMM classifier is trained by using the fuzzy Gaussian parameters to classify the speaker's accent. The experimental results show that the proposed method outperforms the Gaussian Mixture models, Vector Quantization modeling method, Hidden Markov Model, and Radial Basis Neural Networks.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128931924","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}

File transfer is one of the basic forms of communication. Reliability is the key issue raised due to complex nature of network and growth of computer science. In this paper we have devised a technique for file transfer which identifies whether some portion of the file is received corrupt or not, and if yes then exactly what portion is corrupt. This technique provides reliability by eliminating the corruption from a file, hence requiring less bandwidth of the network by reducing the amount of data to be re-sent in case of corruption. The reliability is ensured with the help of file signature generation method which we have devised in this paper. The beauty of this technique that it generates hashes which are not easy to break, hence ensuring security of the file. We have used TCP as the underlying protocol, whereas TCP is already considered to be reliable, but the fact is that it does not ensure the reliable transfer over the network due to the fact that it uses CRC which is still vulnerable to network conditions and malicious attacks. Our technique operates at the application layer and tries to finish the cope up with the reliability over the file transfer. We have also developed a prototype to test the integrity of our technique. Empirical results ensure the reliability of our technique. The emphasis of this paper is to provide users with the corrupt free file transfer over the network, so that their time and valuable resources might be saved.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128300392","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}
