—Reversible data hiding can recover the original
image from the marked image without any distortion. This
paper presents a novel prediction error based reversible data
hiding method using histogram shifting in spatial domain.
Three predictors including Mean, JPEG lossless and median
edge detector (MED) are employed to compute prediction
values for current pixels, respectively. Prediction errors are
calculated as well to build histogram bins. Histogram shifting
mechanism is designed that bins with large prediction errors
are shifted based on hiding level, and thus, it will not hurt
marked image if hiding level is not high. Histogram bins with
small error predictions are used to hide secret data.
Experimental results demonstrate that average of prediction
error is less than that of interpolation error used in existing
data hiding methods, and the proposed method is good at high
capacity hiding. MED is the best predictor among three
predictors in the proposed method, and it outperforms existing
data hiding methods in terms of capacity and marked image
