| Abstract | In this paper, we propose an improved multiplicative spread spectrum (IMSS) embedding scheme for data hiding by exploiting the multiplicative characteristic to maintain the attractive property of having good quality in IMSS and reducing the interference effect of the host signal in the original multiplicative spread spectrum (MSS) embedding to improve the decoding performance. We first derive the optimal decoder for MSS. We then propose the IMSS approach by exploring the decoder structure of MSS to remove the interference effect of the host signal as much as possible, and derive the optimal decoder for IMSS which remains the simple structure as in MSS and does not require additional information at the receiver side. Simulation results clearly demonstrate the superiority of the proposed IMSS scheme over the MSS one. |

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.
