Abstract

In this paper, we propose partial encryption of JPEG2000 coded image data using an AES symmetric block cipher. We find that encrypting 20% of the visual data is sufficient to provide a high level of confidentiality. This percentage of encryption also provides security against replacement attacks, which is discussed at length.
