概要 Considering the file size in crease and visual distortion of the JPEG image with secret data,a
reversible data hiding algorithm ofJPEG images based on distortion-extension cost is proposed.
Histogram shifting is used to realize reversible embedding ofsecret data,focusing on how to
adaptively select embedding frequency and image block according to embedding capacity,so as to
minimize the visual distortion and file size increase of JPEG image with secret data.This paper
discusses and analyzes the rationality of determining the frequency embedding sequence by simulating
the unit increase of file size of different frequencies, and determining thei mage block embedding
sequence by the number of zero alternating current coefficients and smoothness of the image block.
