This paper is focused on theinvestigation of the existing reversible data hiding method using AMBTC compressed images.In this method, multilevel histogram shifting technique is used to hide the confidential data. After the implementation ofsame method with same test images, experimental results are differ significantly from the results quoted in the existing paper. The experimental evaluation shows that the PSNR values aredepended to the embedding level, but existing paper reveals that the PSNR values are independent to the embedding level.
