| Abstract | Several techniques have been proposed for information hiding including hiding in slack space, which is the focus of this paper. However, current techniques of hiding in slack space depend on utilizing exiting slack space on the disk, which can be seriously limiting. Also, all techniques proposed thus far for hiding in slack space are impacted by the cluster size on the disk since the maximum slack space is a function of the cluster size. This necessitates splitting the data to be hidden into numerous parts, making it cumbersome to remember their locations and sequence for reassembly. Finally, hiding in existing slack space risks loss of data due to overwriting if the file - whose slack is used for hiding - grows in size. In this paper we propose - HIDEINSIDE - a novel on-demand slack space generator that creates new files on-the-fly that act as the cover file for hiding. The proposed method is an Antiforensics as well as a Steganographic technique. With HIDEINsIDE, the information to be hidden is split into n chunks - where n is the number of cover files created. The number of cover files created depends on the amount of data to be hidden and the size of the clusters. Each chunk of data is then encrypted and stuffed randomly into the slack space of one of the n cover files along with the MD5 hash value of the encrypted chunk. We finish the hiding process by creating a map-file of the randomly hidden chunks such that they can be easily reassembled in the correct sequence upon retrieval. The MD5 hash verifies the integrity of the retrieved chunks before they are deciphered. The map-file resides on an external drive making it extremely difficult, if not impossible, to locate, decrypt and reassemble the hidden chunks in the correct order to retrieve the hidden information. |

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.
