چکیده
An optimized method for data hiding into digital color image in spatial domain is provided. The graph coloring theory with different color number is applied. To enhance the security of this method, we use block correlations method in the image. Experimental results show that with the same PSNR, the capacity was improved about %8 and also security increased in the purposed method compared with other methods. Data hiding capacity of the host image in correlation block-based image method is changed according to image type and defined threshold level. These two parameters, in addition to the capacity and factor of safety (based on the host image change) is also determined. In the proposed algorithm, during graph explanation independent pixels located each other and colored. Then based on pixel block correlation data hiding process is done. This method increases security and capacity of hiding process and will decrease the effect of image format and correlation threshold on security and capacity.
