A new reversible high capacity hiding algorithm using decomposition and simple arithmetic operations is proposed in this paper for hiding gray-scale and RGB images. Generally, the three factors that should be taken into account in hiding algorithms are the capacity, security, and invisibility of secret information. The Least Significant Bit method is a popular technique to hide operations in the spatial domain. A number of methods were proposed to enhance the performance of the Least Significant Bit method. However, the capacity and security levels of those algorithms are low. The target of the proposed algorithm is implementing hiding capacity about 75% (6 bits per pixel) to hide an image in another image of the same size and type. In this paper, we use an encrypted image as a cover image to reduce the effects of distortion. The bit planes that result from decomposing the secret image will be reordered and scrambled before the hiding operation to make it invisible. Also, the hiding operation is achieved by subtracting or adding numbers to the host pixel value based on the value of the secret pixel to increase the security level. Experimental results show that the capacity of the proposed method is perfect with a high quality of the extracted image, which is strong against many attackers.
