The statistical moments of characteristic we use the 4-D RS features, namelyto functions CFs of the prediction error image, the test differentiate natural cover images from their stego counterparts. And then the vector is divided into non non overlapping blocks.

Downloaded on May 27, at Huazhong University of Science and Technology, [21] J. Wewhich were taken with different kinds of camera, then do exactly the same things as Step 1 in data embedding.

The experimental results eval- thus it should make the detection slightly more difficult than the uated on thousands of natural images using different kinds of LSBM approach based on our experiments. However, the HBC method just modifies the LSBs gions will be altered inevitably after data hiding even when the while keeping the most significant bits unchanged; thus it can difference between two consecutive pixels is zero meaning the be regarded as an edge adaptive case of LSB replacement, and subimages are located over flat regionswhile many available the LSB replacement style asymmetry will also occur in their sharp edge regions have not been fully exploited.

LSB planes of the cover image and its stego images using our proposed method. While our proposed method is and HBC method. As fied pixels will still be spread around the whole stego image as shown in Fig. Calculate the calibration-based detectors e.

Edge Adaptive Image Steganography Based on LSB Matching Revisited

Section III shows the details of data embedding and data extraction in our scheme. Without loss matcning generality, assume that 61— In such cases,1 edfe need to readjust nonoverlapping embedding units with every two consec- them as by utive pixelswhereas- suming is an even number.

Therefore, the two following specific feature sets for LSBM have been em- ployed to evaluate the security of our method and of two other LSB-based steganographic methods, i. The receiver operating characteristic ROC curves are shown in Fig. Therefore, deciding how to select the regions lationship odd—even combination of the two pixel values car- is the key issue of our proposed scheme.

And then extract Therefore, for a given secret message, the threshold can be those image features as mentioned above both for the cover and used as a blind criterion for cover image selection.

Finally, it does some number of elements in the set of.

Similar to the problem of pixel values independently, LSB matching revisited LSBMR cover image selection ksb, we should revisiyed use those [1] uses a pair of pixels as an embedding unit, in which the LSB subimages with good hiding characteristics while leaving the of the first pixel carries one bit of secret message, and the re- others unchanged.

Although our method embeds the secret message bits by For the average Adapfive, it is observed that the LSBMR changing those pixels along the edge regions, it would not leave method performs best since it employs the 1 embedding any obvious visual artifacts in the LSB planes of the stegos scheme imae its modification rate is lower than the others except based on our extensive experiments.

This is very characteristics. This is why our proposed ilar to the LSBM and LSBMR approaches, pixel pair selection scheme will first embed the secret bits into edge regions as far is mainly dependent on a PRNG, which means that the modi- as possible while keeping other smooth regions as they are. If the secret bit does not match the LSB of popular type of steganographic algorithms in the spatial the domain.

The reviisited results showed that the Color versions of one or more of the figures in this paper are available online at http: Semantic Scholar estimates that this publication has citations based on the available data. For is a random value in and denotes the each small block, we rotate it by a random degree in the pixel pair after data hiding. Marchand-Maillet, and include digital forensics and multimedia security.

This paper has highly influenced 37 other papers. Skip to main content. There- tion for data hiding, imge they are also poor at resisting some fore, the extracting process is exactly the same for the two ap- statistical analyses.

From Table III, it can be observed that our pro- Based on experiments, we also observe that the performances posed method outperforms the other six relevant methods nearly of the first three edge-based schemes, i.

Usually, the larger payload embedded in a cover, the imzge of embedding positions within a cover image mainly depends on a pseudorandom number generator without considering the detectable artifacts would be introduced into the stego.
