Secure distribution of watermarked images for a digital library of ancient papers

Abstract

The electronic publishing, storage and distribution of documents is growing increasingly important and will have profound implications for our economy, culture and society. The multimedia digitalisation of libraries and the distribution of the contents of museums is revolutionising these organisations and will make these resources available to a much wider audience than was previously possible.The main goal of our MEDIA project (Mobile Electronic Documents with Interacting Agents) is the development of a system for the archival, retrieval, and distribution of electronic documents. For this purpose, a mobile agent platform is used to securely distribute these documents. Information is accessed by a search mechanism that allows the retrieval of text and images according to their content.An important feature of the system is a digital watermarking tool which embeds hidden signatures in images. This provides copyright protection and helps to ensure that the image will not be copied and sold and without proper authorisation.The management of the database of documents and images is accomplished by an extensible object relational database management system. In addition, documents and data can be accessed through the World Wide Web network.

“…The goal of ASAP is to deliver an execution platform that supports development of applications based on mobile software agents. This KryPict project's [23] main goal is to develop copyright enforcement and document authentication methods that will allow to digitally watermark images. As a result, information providers will be able to make accessible their images over the network without having to fear that these images will be stolen and that their copyright be infringed.…”

Reversible data hiding and lossless reconstruction of binary images using pair-wise logical computation mechanism

“…Recently, the hiding of annotation, side information or confidential data inside an image covered by its unsuspicious outlook attracts certain interest in some applications, such as digital library [6][7][8][9][10][11]. Although most researchers focus on the research issues of indexing, classification, content retrieval or knowledge management in digital library, the needs of on-line information searching and datum downloading gradually emerge that result in the problems of data tampering and content authentication.…”

Watermark: From Paper Texture to Digital Media

“…Combining back-lighting technique with various image processing operations is considered one of the most popular techniques [13,14,15,16,17,18]. This combination has the advantage of giving accurate results, with optimal time and cheap requirements.…”

“…Rauber et al [15,16] proposed a system for the management of a database of historical papers which contains watermark. The system supports several different types of queries to locate and retrieve an existing watermark design from the database, including textual search and shape-based queries [17].…”
