| Abstract | This paper proposes novel robust multiple watermarking technique for color images in spatial domain. The host image is divided into four different regions. Each region consists of four 128*128 blocks in order to hide a watermark. The watermark is a binary image, encrypted and embedded into different regions of the blue component of the host image by altering intensity values of the selected region. Five watermarks can be extracted by comparing the intensities of the selected region of the original image with the corresponding region of the watermarked image. The extracted watermark bits can be determined by calculating the probability of detecting '0' or '1'. Only one watermark will be selected or built from the five extracted watermarks according to the highest value of the normalized cross correlation (NCC). The proposed watermarking technique is shown to be robust for a wide range of attacks, including JPEG2000, JPEG compression, rotation, cropping, scaling, self-similarity, rotation-scaling, rotation-cropping and filtering. |

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.
