| Abstract | An illicit photography work can be exposed by its unusual compression history. Our work aims at revealing the primary JPEG compression of a camera image especially when it has undergone an out-camera JPEG compression. The proposed method runs a recompression operator on a given image using a chosen software tool (MATLAB). We measure the JPEG error between the given image and the recompressed version in the Y, Cb and Cr color channels. The in-camera compression can be easily identified by drawing the JPEG error curves. In this paper a simple and high effective method is presented for automatically detecting the compression history of an image. For a doubly compressed image, the proposed method can give the historical compression sequence with the corresponding quality factors and determine whether the first compression is the in-camera compression. Experimental results, carried out on two datasets, show that the proposed method can yield satisfactory detection accuracy, over 96 % accuracy rate for in-camera compression and no false positives with a block size of 512 × 512. The proposed method has universality. It can be applied to multi-compression detection and is robust to different sources of out-camera compression, e.g. Adobe Photoshop. This makes it more practical compared to the previous methods of double compression. |

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.
