Embodiment Construction
[0035] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] The present invention proposes a data hiding method based on an image set. The image set is used to generate a larger histogram peak value and the capacity of information hiding is improved; the basic image corresponding to the difference image with the lowest histogram peak value is used to perform the final dense image With special encryption processing, more secure and lossless data hiding is realized. The original carrier image is processed to prevent overflow, and the reserved pixel area is opened to produce the carrier image. The carrier image is subtracted from the basic image in the constructed image set to obtain the difference image and histogram information. The difference image with the largest histogram peak is used as the carrier, and the histogram-based information hiding method is used to hide the data, and the...
