| Abstract | To increase the security of messages sent over internet steganography is used. Various steganography techniques have been proposed so far. Least Significant Bit steganography is one such technique in which least significant bit of pixels of the image is replaced with data bits. This approach has the advantage that it is simplest one to understand, easy to implement and results in stego-images that contain embedded data as hidden. The disadvantage of Least Significant Bit is that it is vulnerable to steganalysis and is not secure at all. So as to make it more secure, the least significant bit algorithm is modified to work in different way. This proposed approach simply does not pick up least significant bits of pixel in a sequence but is combined with midpoint circle approach to choose which pixels are used to hide message. The goals of this paper are to present theoretic analysis of Least Significant Bit approach and to propose an advanced LSB embedding scheme that exhibits not only the advantages of LSB but also provides additional level of security. The scheme breaks the regular pattern of LSB, resulting in increased difficulty of steganalysis and thereby raising the security level. |

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.
