In this paper we propose a new steganography technique which embeds the secretIn this paper we propose a new steganography technique which embeds the secretmessages in frequency domain. According to different users’ demands on the embedding capacityand image quality, the proposed algorithm is divided into two modes and 5 cases. Unlike thespace domain approaches, secret messages are embedded in the high frequency coefficients resultedfrom Discrete Wavelet Transform. Coefficients in the low frequency sub-band are preservedunaltered to improve the image quality. Some basic mathematical operations are performedon the secret messages before embedding. These operations and a well-designed mappingTable keep the messages away from stealing, destroying from unintended users on the internetand hence provide satisfactory security.ABSTRACT
