“…After the embedding process the watermarked data is usually attacked (otherwise there is no point in carrying out experiments) [2]. In this article we focus on image processing attack such as: white noise, resize, median filtering, low-pass filtering, Gaussian noise, jpeg compression, color depth reduction which are commonly used by photographers and web developers, see [6].…”

“…Digital Watermarking is one of possible technologies which can be used for protecting intellectual property of digital content [2][3][4][5]. The research performed by the author, published in [6] has demonstrated that there is no commercial software nor technology which satisfies all requirements of robust digital watermarking. As a result there is a strong need to develop new robust watermarking algorithms.…”

Abstract. Recently, a variety of digital watermarking schemes have been developed for copyright protection of digital images. In robust watermarking, which is used in copyright protection, transform-based algorithms are used to ensure resilience of the watermark to common signal processing attacks. The most frequently used watermarking algorithms for additive watermark embedding involve DCT, DFT, SVD and DWT domains. In this article we verify which domain is optimal for robust, the additive watermark embedding scheme. We demonstrate that in additive watermark embedding the embedding domain plays more important role than the embedding formula.

The numerous tribology problems occurring in power-train and transport industry lead to wear of vehicles and trains as well as to wear of road or tracks. The choice of the proper way traffic or transport requires to select the kind of the way and the kind of the vehicles which shall be driving on the track. Especially the project designer demand the more and more information referring the wear of track anticipation in succeeding years of vehicle operation. Such wear of track anticipation is strictly connected with the choice of the kind of communication or traffic. To satisfy the abovementioned problem, it is necessary to construct the logical control system for road traffic. Mentioned logical system enables to control of management of the road traffic or railway junction. The presented in this paper logical system consists the description of the logical functors and their mutually connections. Here are introduced three kinds of functors namely, open functor, closed functor and special functor. Each logical functor describes the signal features which will be controlled. The various functor connections occurring in considered communication systems are determined from practical problems where the influence of various operating parameters on the wear effects is taking into account. The influence of numerous operating parameters on the wear effects are experimentally determined and implemented into the systems in the case if mentioned parameters are independent as well if are mutually connected. Moreover in this paper the various communication systems will be presented and will be suggested an algorithm construction of the optimum problem solutions presenting the equivalent and simultaneously most simple communication system.

Abstract. This paper proposes and evaluates a watermarking-based approach to certify the authenticity of iris images when they are captured by a genuine equipment. In the proposed method, the iris images are secretly signed before being used in biometric processes, and the resulting signature is embedded into the JPEG carrier image in the DCT domain in a data-dependent way. Any alteration of the original (certified) image makes the signature no longer corresponding to this image and this change can be quickly identified at the receiver site. Hence, it is called fragile watermarking to differentiate this method from regular watermarking that should present some robustness against image alterations. There is no need to attach any auxiliary signature data, hence the existing, already standardized transmission channels and storage protocols may be used. The embedding procedure requires to remove some part of the original information. But, by using the BATH dataset comprising 32 000 iris images collected for 1 600 distinct eyes, we verify that the proposed alterations have no impact on iris recognition reliability, although statistically significant, small differences in genuine score distributions are observed when the watermark is embedded to both the enrollment and verification iris images. This is a unique evaluation of how the watermark embedding of digital signatures into the ISO CROPPED iris images (during the enrollment, verification or both) influences the reliability of a well-established, commercial iris recognition methodology. Without loss in generality, this approach is targeted to biometric-enabled ID documents that deploy iris data to authenticate the holder of the document.
