JPEG Quantization Step Estimation and Its Applications to Digital Image Forensics
2017
IEEE Transactions on Information Forensics and Security
Preserved Fulltext
The goal of the paper is to propose an accurate method for estimating quantization steps from an image that has been previously JPEG-compressed and stored in lossless format. ...
The proposed method can also be exploited to estimate the secondary quantization table in a double-JPEG compressed image stored in lossless format, and detect the presence of JPEG compression. ...
Compared with passive forensics, active forensics that relies on extrinsic security measures such as digital watermarks [3] and digital signatures [4] is of limited application due to many strict constraints ...

As society has become increasingly reliant upon digital images to communicate visual information, a number of forensic techniques have been developed to verify the authenticity of digital images. ...
Furthermore, we show how these techniques can be used to render several forms of image tampering such as double JPEG compression, cut-and-paste image forgery, and image origin falsification undetectable ...
This technique detects previous applications of JPEG compression by using the DCT coefficient distributions to estimate the quantization step size used in each DCT subband during JPEG compression. ...
