| Abstract | An access control model based on credibility is proposed. The Community Authorization Service (CAS) is an authentication technology which allows service providers to delegate some policy authority to the virtual organization. While in open distributed systems, provider join or leave the domain frequently, so access-control policy in the server changes quickly. To reduce the server load, threshold value of credibility and a weight factor are applied in the model, and use Analytic Hierarchy Process (AHP) to analyze the weight of every rule. Providers adjust the threshold value and weight factor instead of changing policies in the server. First the server authenticates the requestor and gives him credibility, then synthesizes the credibility and trustworthiness. If the synthesis of credibility achieves the threshold value, the server gives him a certificate. The authentication policies and trustworthiness are both used in the model, thus flexibility and robustness are the advantages of this model. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
