An efficient and robust method for detecting copy-move forgery
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By Sevinc Bayram, Husrev Taha Sencar, Nasir Memon
Issue Date:April 2009
pp. 1053-1056
Copy-move forgery is a specific type of image tampering, where a part of the image is copied and pasted on another part of the same image. In this paper, we propose a new approach for detecting copy-move forgery in digital images, which is considerably mor...
 
Flatbed scanner identification based on dust and scratches over scanner platen
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By Ahmet Emir Dirik, Husrev Taha Sencar, Nasir Memon
Issue Date:April 2009
pp. 1385-1388
In this paper, a novel individual source scanner identification scheme is proposed. The scheme uses traces of dust, dirt, and scratches over scanner platen on scanned images to characterize a source scanner. The efficacy of the proposed scheme is substanti...
 
An Ensemble of Classifiers Approach to Steganalysis
Found in: Pattern Recognition, International Conference on
By Sevinc Bayram, Ahmet Emir Dirik, Husrev Taha Sencar, Nasir Memon
Issue Date:August 2010
pp. 4376-4379
Most work on steganalysis, except a few exceptions, have primarily focused on providing features with high discrimination power without giving due consideration to issues concerning practical deployment of steganalysis methods. In this work, we focus on ma...
 
Video copy detection based on source device characteristics: a complementary approach to content-based methods
Found in: Proceeding of the 1st ACM international conference on Multimedia information retrieval (MIR '08)
By Husrev Taha Sencar, Nasir Memon, Sevinc Bayram
Issue Date:October 2008
pp. 1-1
We introduce a new video copy detection scheme to complement existing content-based techniques. The idea of our scheme is based on the fact that visual media possess unique characteristics that can be used to link a media to its source. Proposed scheme att...
