    Opis:
    Steganography is a technique that allows hidden transfer of data using some media such as Image, Audio, Video, Network Protocol or a Document, without its existence getting noticed. Over the past few years, a lot of research has been done in the field of Image, Video and Audio Steganography but very little work has been done in Network Steganography. A Network Steganography technique hides data in a Network Data Unit, i.e., a Network Protocol Packet. In this paper we present an algorithm ARPNetSteg that implements Network Steganography using the Address resolution protocol. Our technique is a robust technique that can transfer 44 bits of covert data per ARP reply packet.

    This paper summarizes the experience and the learning outcomes of students of the "Informatics" specialty at the Episkop Konstantin Preslavsky University of Shumen (Bulgaria) on the problems of computer and network security as a component of their professional training. It is a continuous process starting from the "Computer steganography" course and turning into diploma papers, masters programs, specializations and PhDs in computer and network steganography. The outcome of this training would be bachelors and masters theses, practical activities of experimentation of stego software and steganology in a parallel computing environment, joint scientific publications of lecturers and students.

    Opis:
    Science 2.0 aims at using the information sharing and collaborative features of the Internet to offer new features to the research community. Science 2.0 has been already applied to computer sciences, especially bioinformatics. For network information hiding, a field studying the possibility of concealing a communication in networks, the application of Science 2.0 is still a rather uncovered territory. To foster the discussion of potential benefits for network information hiding, we provide a disquisition for six different Science 2.0 aspects when applied to this domain.

    Opis:
    This research proposes a method to enhance the payload message by embedding messages on the dilated edge areas by the Least Significant Bit (LSB) method. To add security aspects to messages, messages are not embedded directly on the LSB but encrypted with XOR operations with Most Significant Bit (MSB). The experimental results of the test in this study showed that the dilation process to some extent can increase the payload of 18.65% and the average bpp is 1.42 while maintaining the imperceptibilty quality of stego image with an average PSNR value of about 47 dB, SSIM is 0.9977 and MSE is 1.13.

    Opis:
    In the recent years, several digital watermarking applications have been developed for copyright protection of digital images. In this article we have tested how they perform in practical applications. We have identified the most common operations performed by professional photographers and web developers, and tested the robustness of watermarks embedded using the applications for copyright watermarking. Our aim was to prove that commercially available software does not meet the requirements of photography and web industry. We have also identified areas in which the software should be improved in order to meet current and future requirements of the industry.

    We propose a novel least significant bit steganography algorithm based on a Hitzl-Zele chaotic function. On the first step a pseudorandom generator is constructed for chaotic pixel selection for hiding the secret message. Exact study has been provided on the novel scheme using visual inspection, peak signal-to-noise ratio, and histogram analysis. The experimental data show excellent performance of the novel stego technique.

    Opis:
    Extensive use of computer networks is associated with the development of various effective methods that are suitable for hiding information in the contents transferred over the network. These methods are described as network steganography. Since web applications use HTTP protocol to transmit the requests to the server and send the answers to the final recipient, specifically HTTP protocol is ideal for hiding information. For example, there are several methods that can be used to transmit the additional content in the HTTP header. In this paper, we present authors’ evaluation method for network steganography using HTTP specific properties and evaluate the effectiveness of some techniques, providing experimental results.
    Szerokie zastosowanie sieci komputerowej jest związane z rozwojem wielu skutecznych metod, które są odpowiednie do ukrywania informacji w treściach przesyłanych poprzez sieć. Metody te są określane mianem steganografii sieciowej. Ponieważ aplikacje internetowe używają protokołu HTTP do przesyłania żądań do serwera i wysyłania odpowiedzi do końcowego odbiorcy, protokół HTTP jest idealny do ukrywania informacji w szczególności. Na przykład, istnieje kilka metod, które mogą być wykorzystane do przesyłania zawartości dodatkowych w nagłówku HTTP. W tym artykule przedstawiono autorski sposób oceny metod steganografii sieciowej za pomocą konkretnych właściwości HTTP i dokonano oceny skuteczności niektórych technik, podając wyniki doświadczalne.

    This article presents a new method for detecting a source point of time based network steganography - MoveSteg. A steganography carrier could be an example of multimedia stream made with packets. These packets are then delayed intentionally to send hidden information using time based steganography methods. The presented analysis describes a method that allows finding the source of steganography stream in network that is under our management.

    Opis:
    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.

    Opis:
    The paper presents the analysis of the Commercial Off-The-Shelf (COTS) software regarding the ability to be used in audio steganography techniques. Such methods are a relatively new tool for hiding and transmitting crucial information, also being used by hackers. In the following work, the publicly available software dedicated to audio steganography is examined. The aim was to provide the general operating model of the information processing in the steganographic effort. The embedding method was analyzed for each application, providing interesting insights and allowing classifying the methods. The results prove that it is possible to detect the hidden message within the specific audio file and identify the technique that was used to create it. This may be exploited further during the hacking attack detection and prevention.
