Handling and analysis of microarray data is a most challenging task. The cluster analysis is one of the important high level analysis techniques, often exploited for microarray data analysis. As proteins usually related with different groups of proteins in order to handle diverse biological roles, the genes that create such proteins are thus expected to interact with more than one group of genes. This construes that in micro array gene expression data, a gene may make its presence in more than one cluster. The prior research has expressed the presence of genes in one or more clusters consistent with the nature of the gene and its attributes by the two dimensional clustering technique. The competence of the clustering analysis depends on the designing of an efficient (dis) similarity measure for grouping them. This research, has improved the prior cluster analysis research via an efficient hybrid distance based similarity measure. The proposed technique is implemented and its performance is evaluated with microarray gene expression data.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128610237","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 method uses a NN-PSO (Neural Network-Particle Swarm Optimization) based hybrid approach to watermark host gray scale fingerprint images with their corresponding facial images in order to secure them. The algorithm divides the input image into blocks and uses a feed forward NN to determine the number of secret bits to be embedded in each block depending on the blocks' features. The output of the NN is then used as input by the PSO module to find the best DCT coefficients' locations in that block where the secret facial image data can be embedded, so that the distortion produced in the host image is minimum and the minutia predicting ability remains unaffected. The experimental results have been analyzed and compared with existing PSO based and NN based approaches. The proposed NN-PSO based hybrid approach has been found to exhibit better watermarked image quality and better robustness to possible attacks to the watermarked image. Moreover, as the proposed technique retains the feature set of the original fingerprint, the extracted facial image and the cover fingerprint image can be correctly verified at the receiver's end leading to a more secure and accurate biometric based personal authentication.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127699599","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 data centric applications hosted on the cloud, data is accessed and updated in a purely distributed manner. The distributed data structures used for dynamic storage of the data for such applications require two fundamental qualities, authentication and persistence, which are not completely met by existing distributed data structures. Authentication is a crucial requirement for data structures used on the cloud, as users need to be convinced about the validity of the data they receive. Moreover the data structure has to be persistent, so that changes can be made to the data structure without losing old data, or old versions of the data structure, which may be required by different users in the distributed environment.\u0000 In this paper we present authenticated and persistent skip graph, an enhanced variant of the existing skip graph. It is based on an event based model, to correspond to the distributed data centric application requirements. Skip graphs are randomized data structures based on skip lists, proposed for use in distributed applications. But skip graphs are neither persistent nor authenticated. The fat node technique is adapted here for providing persistence, and a role based access control, with a cryptographic scheme is used to ensure valid data update and verify the validity of the retrieved data. Our data structure is proved to be efficient in terms of time and space complexities.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128653206","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}
