“…The amount of authentication information used for the tamper detection is subject to the constraint of condition (4). Therefore, those lossless watermarking approaches with low capacity 7,8,12 are unable to provide sufficient localization accuracy. The property of retrievability is the key to the success of tamper localization.…”

“…In the prediction-error based algorithm of Thodi et al, 13 a slight modification of image data may lead to drastic change of the context used for prediction, which leads to failure of watermark extraction and restoration. The discussion above indicates that many current lossless watermarking methods [7][8][9][10][11][12][13] are not good candidates for embedding local authentication information directly into the watermark payload.…”

Lossless Watermarking for Verifying the Integrity of Medical Images with Tamper Localization

Given the ease of alteration of digital data, integrity verification and tamper detection for medical images are becoming ever more important. In this paper, instead of using the conventional irreversible block-based watermarking approach to achieve tamper localization, we propose to incorporate such functionality into the regionbased lossless watermarking scheme. This is achieved by partitioning an image into certain non-overlapping regions and appending the associated local authentication information directly into the watermark payload. A region of authentication, which can be flexibly specified by the user, is partitioned into small regions in a multilevel hierarchical manner. Such hierarchical structure allows the user to easily adjust the localization accuracy, and makes the tamper detection efficient. Experimental results demonstrate the effectiveness of tamper localization.

“…The advantages of using watermarking include enabling authentication information such as the metadata to be embedded into the medical images as visually unperceivable watermark payload and providing continuous authenticity and integrity protection of the images beyond the point of internal network. A number of digital watermarking techniques for medical images have been reported [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. These watermarking techniques can be broadly categorized into non-reversible [3,4] and reversible watermarking [2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] in the literature where reversible watermarking has been more widely implemented.…”

An Improved Tamper Detection and Localization Scheme for Volumetric DICOM Images

The development of teleradiology brings the convenience of global medical record access along with the concerns over the security of medical images transmitted over the open network. With the prevailing adoption of three-dimensional (3-D) imaging modalities, it is vital to develop a security mechanism to provide large volumes of medical images with privacy and reliability. This paper presents the development of a new and improved method of implementing tamper detection and localization based on a fully reversible digital watermarking scheme for the protection of volumetric DICOM images. This tamper detection and localization method utilizes the 3-D property of volumetric data to achieve much faster processing time at both sender and receiver sides without compromising tamper localization accuracy. The performance of the proposed scheme was evaluated by using sample volumetric DICOM images. Results show that the scheme achieved on average about 65 % and 72 % reduction in watermarking and dewatermarking processing time, respectively. For cases where the images had been tampered, it is possible to detect and localize the tampered areas with improved localization resolution in the images using the scheme.

Over the past few years, reversible watermarking techniques for relational databases have been proposed to provide protection of ownership rights, data tempering, and data integrity. Mainly, these techniques ensure original data recovery from watermarked data, whereas irreversible watermarking schemes only protect ownership rights. This characteristic of reversible watermarking has emerged as a candidate solution for the protection of ownership rights of data, intolerable to modifications such as medical data, genetic data, credit card, and bank account data. The main objective of this paper is to make an extensive survey of the state-of-the-art in reversible watermarking techniques for relational databases to reflect recent research progress and to point out the key issues for future research. In order to analyze these techniques, a classification has been performed on the basis of (i) the extent of modifications introduced by the watermarking scheme in the underlying data and (ii) the robustness of the embedded watermark against malicious attacks.Reversible watermarking techniques [10,11,26] provide security for trial versions of database applications. The original full version of the database application can be recovered from the decoded database subsequently, dependent on whether the user purchases the license of the database application. For example, database applications providing this facility are IBM DB2 [27] and Oracle [28]. High-capacity watermarkingReversible watermarking techniques provide a mechanism to utilize the available bandwidth for maximum water-Security Comm. Networks (2015) A survey on reversible watermarking techniques for RDB mark robustness by minimizing distortions in the data and increasing watermark capacity [29,30]. With high watermark capacity, less distortion is introduced in the underlying data. High-capacity watermarking is required in critical databases such as those pertaining to military and health care domains. Original data recoveryReversible watermarking techniques provide high-quality datasets (without any alterations) for data mining and other information extraction processes [10,11,30,31]. In some relational database applications such as electronic medical records systems, data mining is used to extract patient data for decision making. As increasing amount of medical data is made available by practitioners and health care providers for conversion into digital format, cases of fraud [32] and data privacy breach crop up at an alarming rate [33]. Thus, in such shared environments, ownership and digital rights are required to be protected from illegal use by malicious users.Security Comm.
