Abstract

In this paper, the problem of hiding data in electronic document for adding captions or fingerprints is considered. A new data hiding scheme, which utilizes difference in character-to-character space for data embedding, is presented. Coding and enhancing techniques are proposed as a means to alleviate effects of noise and distortions, possibly arise during document copying or scanning process. Experimental results using documents written in Thai and English are provided to demonstrate its practical applicability. The method's weakness and future work are also discussed.
