| Abstract | Cryptography plays a crucial role in providing security to the sensitive data and information such as medical data. One method to handle sensitive data when it needs to be transmitted from source to the destination is to encrypt the same. Traditionally, Hill Cipher is used to encrypt the data. which uses only 26 characters in English alphabet. So, it is vulnerable to any known plain text attack. Hill Cipher is modified by making use of a set of the 7 bit ASCII characters denoted by codes 0 to 127 in [1]. In the current approach a set of 256 ASCII characters called 8-bit extended ASCII set denoted by codes 0 to 255 are used by implementing interweaving and iteration. At each step of the iteration, interweaving is performed because of which the text undergoes many transformations before it becomes cipher text. In order to diagnose different diseases, the hospital has to share the patient information to the researchers. During such a transmission the data may be modified or hacked by the third party. As medical data is highly sensitive information it has to be encrypted to be secure. Medical records help patients to acquire appropriate and right treatment. If the medical records are modified the patients may receive false treatment and leads to wrong consequences. Since there is also a chance of leakage of medical records from a trusted agent also, so to prevent this, a concept called "adding fake objects" [8] is used which appear as realistic objects and thus helps in identifying the third party who leaked the data. If data is found in other sources like website by using the "agent guilty model" we may find the guilty agent who is responsible for leaking the sensitive data. In this work, we implement these concepts to provide security to medical records. |

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.
