Abstract
There are many of research have been proposed for embedding information into cover images. The LSB approach is a well known method to most of people in the field. It usually assumes that the base of the numerical data being hidden is a whole power of 2. When the base of the number is not a power of 2, a base transform must be used to convert it. The study presents a novel and simple method for high-hiding capacity. The concept is based on the concept of cyclic group. Unlike the other method to improve the quality of stego-image, but the approach of extract secret data is still the same with LSB. Our method escape the frame of LSB, that means the approach to extract secret data is not the same with LSB but the quality of stego-image is even better than other optimal LSB methods
