Detecting Double Compressed JPEG Images
نویسندگان
چکیده
Verifying the integrity of digital images and detecting the traces of tampering without using any protecting pre–extracted or pre–embedded information has an important role in image forensics and crime detection. When altering a JPEG image, typically it is loaded into a photo–editing software and after manipulations are carried out, the image is re–saved. This operation, typically, brings into the image specific artifacts. In this paper we focus on these artifacts and propose an automatic method capable of detecting them.

متن کاملEstimation of Primary Quantization Matrix in Double Compressed JPEG Images
In this report, we present a method for estimation of primary quantization matrix from a double compressed JPEG image. We first identify characteristic features that occur in DCT histograms of individual coefficients due to double compression. Then, we present 3 different approaches that estimate the original quantization matrix from double compressed images. Finally, most successful of them Ne...

Bin Li, Hu Luo, Haoxin Zhang, Shunquan Tan, Zhongzhou Ji Shenzhen Key Lab of Media Information Security, Shenzhen University, P. R. China ABSTRACT Detecting double JPEG compression is important to forensics analysis. A few methods were proposed based on convolutional neural networks (CNNs). These methods only accept inputs from pre-processed data, such as histogram features and/or decompress...
متن کاملEstimation of primary quantization matrix for steganalysis of double-compressed JPEG images
A JPEG image is double-compressed if it underwent JPEG compression twice, each time with a different quantization matrix but with the same 8 × 8 grid. Some popular steganographic algorithms (Jsteg, F5, OutGuess) naturally produce such double-compressed stego images. Because double-compression may significantly change the statistics of DCT coefficients, it negatively influences the accuracy of s...
متن کاملMulti-class blind steganalysis for JPEG images
In this paper, we construct blind steganalyzers for JPEG images capable of assigning stego images to known steganographic programs. Each JPEG image is characterized using 23 calibrated features calculated from the luminance component of the JPEG file. Most of these features are calculated directly from the quantized DCT coefficients as their first order and higher-order statistics. The features...
