Role Of Information Technology In Integrating Biological Databases Into Metabases- A Review

Life science researchers are experiencing a “data explosion” due to vast amounts of raw data being produced genomic, proteomic, and structure predicting experimentation. This exponential growth curve is expected to continue. These piles of data are kept in different databases scattered across the diverse industries, different universities and research institutes throughout the world. There is a dire need for the creation of intelligent database of these databases to query, collect, link, merge, analyze and give biological sense to these different data to tackle more and more intricate and challenging scientific problems. An imperative resource for finding biological databases is a special annual issue of the journal Nucleic Acids Research (NAR).which is freely available and categorizes many of the publicly available on line databases related to biology and bioinformatics. Although a huge variety of database are available online, PubMed maintained by the National Center for Biotechnology Information (NCBI); Ensembl maintained by the European Bioinformatics Institute (EBI) and the Wellcome Trust; the UCSC Genome Browser a human, mouse and rat genome browser maintained by David Haussler’s group at the University of California at Santa Cruz; FlyBase maintained by the FlyBase Consortium; WormBas, and the Gene Ontology (GO) database exemplify some of the major biological databases.

E-Security: Proposed Algorithm Of Authenticity Of Digital Signature

The increasing use of digital signature in electronic documents poses special challenges in verifying authenticity, because digital technology makes such documents easy to alter or copy, leading to multiple non-identical versions that can be used in unauthorized or illegitimate ways. To help meet the challenge of the digital age but also provide the assurance that an electronic document has not been altered. A digital signature, viewed through authenticity, verifies documents, at no cost to the customer. [12] Everyone is used to dealing with an original document, or an authenticated copy of the original document, but is in difficulties when the concept of ‘original’ proves to be elusive in respect of a digital signature, whatever form it takes. [8] Data and information security becomes more and more important in digital signature which uses a public high-speed wide area network. Generally, E-security is characterized in terms of privacy, authenticity and integrity of digital data. [14]Authentication is concerned for both information providers and information users thought the process. [5]This paper proposed an algorithm with flowchart of authenticity of digital signature that gives us generalization to check security and authentication of digital signature effectively. ...
