![]() Technological advances, however, have made the printed document easy to modify for malicious purposes. Experimental results show that this method has an average accuracy of 90% and works with JPEG compression.Įven in the age of the Internet and digital communication, paper is used extensively as an important carrier of information. To the best of our knowledge, this is the first work to distinguish documents produced by laser printer, inkjet printer, and copier based on features extracted from individual characters in the documents. Based on the analysis of these signatures, we computed the features of noise energy, contour roughness, and average gradient. We analyze the characteristics associated with laser/inkjet printers and electrostatic copiers and determine the signatures created by the different physical and technical processes involved in each type of printing. Hence, it can also be used to detect tampered documents produced by a mixture of these sources. The proposed approach can distinguish between documents produced by these sources based on features extracted from the characters in the documents.
