摘要

JPEG图像因具有出色的压缩比和图像品质被广泛应用于实际案例.考虑到人们对其隐私侵犯的担忧,本文提出了一种有效的加密JPEG比特流可逆信息隐藏方案,旨在为秘密消息和载体提供安全和隐私.首先,采用一种具有格式兼容性和文件大小保留性的加密算法将明文JPEG图像加密为类噪声版本.然后,构建一种基于自适应RZL旋转策略的加密JPEG比特流可逆数据隐藏技术,该技术将秘密消息映射到有序的RZL对序列.授权用户可以从标记的加密JPEG比特流中实现无差错的秘密消息提取并无损恢复原始明文JPEG图像.大量实验表明,与一些最先进的方案相比,本文方案在嵌入容量方面具有较好性能,同时兼具文件大小保留性和格式兼容性.

Abstract

Joint Photographic Experts Group(JPEG)format is extensively used for images in many practical applications due to its excellent compression ratio and satisfactory image quality.Considering compelling concerns about the invasion of privacy,this paper proposes an effective reversible data hiding scheme for encrypted JPEG bitstreams,to provide security and privacy for both secret messages and valuable carriers.First,a format-compatibility and file size preserving encryption algorithm is applied to encipher the plaintext JPEG image into a noise-like version.Then,we present an effective reversible data hiding scheme in encrypted JPEG bitstreams using adaptive RZL rotation,where the secret messages are concealed with the sequence of RZL pairs.When the authorized user receives the marked encrypted JPEG bitstreams,the error-free extraction of secret messages and the lossless recovery of the original plaintext JPEG image can be accomplished separately.Extensive experiments are conducted to show that,compared to some state-of-the-art schemes,the proposed scheme has a superior performance in terms of embedding capacity,while keeping file size preservation and format compatibility.
