Packet-Level Naïve JPEG2000 Information Hiding Using Redundant Packet Insertion Technique

Abstract

Naïve information hiding embeds information data in cover carrier for practical applications such as error correction or image authentication. The positions the information data resides in are not necessarily kept secret. Direct insertion of information data into JPEG2000 codestream can effectively reduce the processing time of information embedding and extraction. However, it may also result in decoding failure for a standard JPEG2000 image viewer. In this paper, we propose a packet-level naïve JPEG2000 information hiding method that uses a redundant packet insertion technique to solve these problems simultaneously. Experimental results show that the full or truncated information-embedded codestream can be correctly decoded by several JPEG2000 Part-1 compliant decoders. That is, the proposed method can meet both the syntax compliance and scalability requirements. Moreover, because the proposed information embedding and extraction processes are performed in packet level, very few decoding operations are involved in the proposed method. That is, the proposed method can meet the simplicity requirement. Therefore, the proposed naïve JPEG2000 information hiding method is very effective and practical for various JPEG2000 applications.
