Data Hiding using Slantlet Fusion Method and T-Codes

Abstract

This paper presents the study of steganography algorithm based on Slantlet fusion method using a self-synchronizing variable length encoder, viz., T-codes. The Slantlet fusion method is the high bit rate data hiding scheme based on Slantlet Transorm. In this method, the fusion process takes place between the SLT of the secret data and the SLT of the cover image. The secret data is obtained by the application of SSVLC, T-codes to the original data. The proposed algorithm is compared with the Wavelet fusion method using the metrics PSNR, PSNRE, PSNRY, CQM, SSIM and KLdiv respectively. It is found that the proposed scheme is highly secure and efficient in comparison to the state of the art works.
