Abstract

Digital fingerprinting is a technique that consists of inserting the ID of an authorized user in the digital content that he requests. This technique has been mainly used to trace back pirate copies of multimedia content such as images, audio, and video. This study proposes the use of state-of-the-art digital fingerprinting techniques in the context of restricted distribution of digital documents. In particular, the system proposed by Kuribayashi for multimedia content is investigated. Extensive simulations show the robustness of the proposed system against average collusion attack. Perceptual transparency of the fingerprinted documents is also studied. Moreover, by using an efficient Fast Fourier Transform core and standard computer machines it is shown that the proposed system is suitable for real-world scenarios.

Highlights

The adoption of information systems is changing the way organizations work, allowing the automation of their processes and making them more efficient
The input documents have been selected from a set of 1000 different digital documents in a JPEG format with average dimensions of 190062700 pixels, these documents have been obtained from [32]
The PSNR and Structural Similarity Index (SSIM) Index metrics used for evaluation of the perceptual transparency in the proposed system are described

Summary

Introduction

The adoption of information systems is changing the way organizations work, allowing the automation of their processes and making them more efficient. One of the recurring processes of these organizations is the management of the document’s lifecycle which is the workflow that defines how users interact with the documents from their creation until their usage in other organization’s processes. Many organizations have digitized their physical documents to automate the document’s lifecycle which depends on the type of information contained in the digital documents, but has a common flow [1,2,3]: 1. Creation: A user generates a digital document. It is determined if the digital document is ready to be released.
