PE Expansion-Based Reversible Data Hiding without Location Maps
نویسنده
چکیده
This paper proposes a prediction error expansionbased reversible data hiding method using no location map. Though a reversible data hiding method once distorts an image to hide data into the image, the distorted image is completely separated to the original image and the hidden data. The proposed method uses only one parameter to extract data; this method extracts data without any location map, whereas conventional prediction error expansion-based reversible data hiding method requires a location map. Experimental results show the effectiveness of the proposed method.

Steganalysis Against Difference Expansion Based Reversible Data Hiding Schemes for 2D Vector Maps
The difference expansion based (DE-based) reversible data hiding schemes suit different types of vector maps respectively, and show good performance, both in capacity and invisibility. In addition, the schemes are strictly reversible. The potential applications of the data hiding schemes may include map data authentication, secret communication, and so on. However, a loophole exists in the DE-b...

متن کاملA Novel Reversible Data Hiding Based on the Prediction Error Image
Reversible data hiding has drawn a lot of interest recently. Being reversible, the original image can be completely restored without distortion. In this paper, a novel reversible data hiding scheme is proposed, which is based on histogram shifting of prediction errors. The JPEGLS prediction method is employed. We apply the peak point of a histogram in a prediction error (PE) image to generate a...

متن کاملRandom Traversing Based Reversible Data Hiding Technique Using PE and LSB
Abstract The rise in the use of internet, secure transmission of the data has become an utmost priority. Steganography makes the data invisible by hiding it in the multimedia such as image, audio or video file and thereby covering for its existence. In this project we use prediction error (PE) technique steganography and Least Significant Bit (LSB) substitution method to hide data in the image....
