Abstract: Data transmitted through a network may be protected from unauthorized receivers by applying techniques based on cryptography. Only people who possess the appropriate private key can decrypt the received data using a public algorithm implemented either in hardware or in software. Fast implementation of encryption-decryption algorithms is highly desirable. Data-content manipulation can be performed for various legal or illegal purposes (compression, noise removal or malicious data modification). The modified product is not authentic with respect to the original one. The technology of multimedia services grows rapidly, and distributed access to such ser-vices through computer networks is a matter of urgency. However, network access does not protect the copyright of digital products that can be reproduced and used illegally. An efficient way to solve this problem is to use watermarks. A watermark is a secret code described by a digital signal carrying information about the copyright property of the product. The watermark is embedded in the digital data such that it is perceptually not visible. The copyright holder is the only person who can show the existence of his own watermark and to prove the origin of the product Reproduction of digital products is easy and inexpensive. In a network environment, like the Web, retransmission of copies all throughout the world is easy. The problem of protecting the intellectual property of digital products has been treated in the last few years with the introduction of the notion of watermarks.

Abstract: Due to increase in the cost of journals, dwindling library budgets and proliferation of electronic information resources, libraries have been involved in cooperation, coordination and collaboration in resource sharing. The emergence of information technology made library professionals to change their role as navigator of information and come closer willingly to share available information with other libraries. Libraries and Information Services (LIS) are being transformed by technology; consequently, LIS have to adopt to meet their user’s changing needs and growing expectations. Included among the resource sharing initiatives conceived by libraries in India is the creation of a computerized network or consortium of all LIS to achieve optimum use. This paper presents the consortia developments in the library and information centers in India. URI: http://hdl.handle.net/1944/1556 Files in this item: 1

Abstract: Open source software (OSS) is popular with technically sophisticated users, who are often also the software developers, and has not yet made a significant impact on the desktop of most users. OSS has much potential for libraries and information centres, and there are a number of projects, including Greenstone, DSpace and Ganesha, etc that demonstrates its viability in this context. OSS is becoming an increasingly popular software development method. This paper highlights what is an OSS, its features, software licensing, advantages and disadvantages. The paper also highlights the features, functions and use of three popular digital libraries software viz. Greenstone, DSpace and Ganesha. URI: http://hdl.handle.net/1944/1573 Files in this item: 1

Abstract: The digital library presents an opportunity for the traditional library and the librarian. Libraries and librarians have significant expertise to offer the creators of digital libraries, for example, skills in organising information.Traditional libraries will not be replaced by digital libraries, certainly not in the near future, and probably never. The reality will be hybrid libraries, with librarians needing to be able to operate in two environments: the first, physical libraries and physical collections; and the second, digital information resources. The goal will be to satisfy the information needs of the user community, regardless of whether the information needed is available in digital form or physical formats.

Abstract: Our information and knowledge environment has been and continues to be changed by the development of the Internet and ubiquitous communication technologies. Information and knowledge are replacing capital and energy as the primary wealth-creating assets, just as the latter two replaced land and labor many years ago. In addition, technological developments in the 20th century have transformed the majority of wealth-creating work from physically-based to “knowledge-based.” Technology and knowledge are now the key factors in development of economy of the country. With increased mobility of information and the global work force, knowledge and expertise can be transported instantaneously around the world. We are now an information society in a knowledge economy where knowledge management is essential. The paper presents an overview of the role of digital libraries in the knowledge economy, its prospects and issues. URI: http://hdl.handle.net/1944/1534 Files in this item: 1

Abstract: Building of Digital Library largely depends on the nature of content and quality of digital resources. The digital library resources include electronic journals, electronic books, fulltext CD-ROM databases, etc. In research and academic institutions, theses, dissertations and research reports play a vital role as primary sources of information since they contain information of research value. Therefore, most of the research scholars refer to these documents regularly. To ensure easy and wider access to these documents, a digital library of theses and dissertations has been established in Tamilnadu Veterinary and Animal Sciences University and connected with the Intranet of the university. The digital library provides access to the constituent units of the university including remote colleges. This paper discusses in brief about the establishment of the digital library of theses and dissertations. URI: http://hdl.handle.net/1944/1563 Files in this item: 1

Abstract: Digitization is also an outcome of development of technologies. The distinct form of art and culture requires preservation for the study of mankind and its progress. Paper stresses need to capture them in digitized form for future interest of the researchers. It will also give an account of art and architecture and sculpture of Malwa region of Madhya Pradesh (India). It had one of the ancient civilizations in India and World. History of Malwa region of Madhya Pradesh (India) dates to prehistoric period. The archeological excavation and heritage structures of Malwa are of no less importance than any other part of India. Much is being done on digitization of manuscripts but very little is thought of these valuable heritage structures lying unprotected and open. Digitization of cultural heritage will be best preservation for future generations’ .The paper suggest for 3 dimensional picturization of these heritages and preserve in digital form. It also suggests for hardware, software and human ware requirements for such work and gives a plan and provides few beautiful slides. A practical LCD projection of digitized heritage site is also prepared. URI: http://hdl.handle.net/1944/1548 Files in this item: 1

Abstract: In present scenario publishers of freely available electronic journals have the potential for positively transforming the highly problematic economics of scholarly publishing. But actual use of electronic scholarly publications shows that they present serious utilization barriers to would-be readers. Practical awareness, indexing, and archiving in this new literature can overcome these barriers and is essential if such promising publications are to transform scholarly communication. DLIST (Digital Library for Information Science and Technology) can meet these needs by integrating electronic publications into existing information systems. Thus disintermediation of the scholarly publishing process will help the clientele of the low budget library in all respects. URI: http://hdl.handle.net/1944/1521 Files in this item: 1

Abstract: The transformation of a scanned paper document into an editable form suitable for further processing such as desktop publishing or archiving in a digital library is a complex process. It requires solutions to several problems – document analysis by acquiring knowledge of document layout by a Page Layout Analyzer (PLA), followed by document recognition, which mainly comprises text recognition by Optical Character Recognition (OCR). Besides these two, another important problem is document reconstruction by transforming content into an electronically editable format by keeping the original layout intact. Core OCR modules exist on different Indian scripts, but no such document reconstruction system is available for Indian scripts. The document reconstruction system reported in this paper is the first of its kind on Indian scripts and it addresses document reconstruction for Bengali document images. The system makes use of the knowledge of both document layout extracted by a PLA in a graphical user interface (GUI) and the results of text recognition steps performed by OCR for transformation of paper documents into Rich Text Format.

Abstract: Since the advent of Unicode, electronic representation of regional language script is not as issue. However, transliteration is inevitable in a database designed to meet the needs of people who does not know that language. By transliteration, a unique name in one language or culture may have variant spelling in another language. The cataloguer maintainsname authority file to solve this problem. This article analyse the optionsfor retrieving transliterated Arabic names in major OPACs. URI: http://hdl.handle.net/1944/1546 Files in this item: 1
