- W2348949942 abstract "A new reversible data hiding algorithm based on histogram modification for grayscale image is proposed,and detailed method of realization is also given.This algorithm utilizes a zero(or minimum point) and maximum point of the histogram of an image and hides data through modifying the pixel grayscale values.In general,reversible data hiding based on histogram modification use one maximum pixel to hide one bit,but the algorithm proposed here uses one maximum point to hide multi-bits,and the number of bit can be determined according to the PSNR between the original image and that after hiding data.Experimental results show that the algorithm can be used to hide high capacity data,and can achieve satisfactory the peak-signal-to-noise ratio(PSNR),and has better performance." @default.
