Information security is a huge trending topic in recent year. Many technique and algorithm were designed and developed toachieve the security of information and/or network across the world. Cryptography is one of the most common tools to provide suchsecurity. Nevertheless, steganography also provide a good security by hiding data within a media in a way that an attacker can't sensethe presence of the secret data. Compression don't normally imply any security , however , it messes up the original encoding of the dataand reduces its size by a measureable amount which makes it perfect for hiding .In this paper a system was proposed where a secretimage is compressed before encryption and hiding. JPEG algorithm was used for the compressing, while at the encryption stage RC4algorithm was used due to its fast processing speed. LSB (Least Significant Bit) technique then applied to hide the secret data within thecover image.

When it comes to preventing unauthorised access to, destruction of, or inspection of confidential data, information security has always been a major factor. Multimedia information is now used in every field throughout the world. The confidential information that is used in these areas must be kept secure. There are a variety of methods for keeping data secure. One of these is steganography, which is concealing information within other data into a format that the cover information remains unchanged. Cryptography, an encryption process that scrambles data into a written form that is sometimes referred to as a hash, is an auxiliary approach for securing information. Steganography and cryptography each have their own set of benefits and drawbacks. Even though both technologies give security, it is usually a good practise to combine Cryptographic algorithms to create additional layers of security. When cryptographic with steganography are combined, a multi-layer security paradigm is created. The proposed work's main goal is to add an additional layer of protection by using cryptography and steganography to encrypt and embed secret data conveyed across an insecure channel.

Achievements in the sphere of automatization and telecommunication are an essential component of transformation of the international peace and security system. This article presents, that consequences of changes are of a dual character. On the one hand, new technologies are becoming an important component of society modernization strategies in developing countries, on the other hand, they can be used for armament modernization or creation of new means of confrontation in modern international relations. APR countries face the most relevant issue of information technologies usage. The article deals with the process of discussion of new challenges and threats to international security, emerging as a result of development and large-scale implementation of information-communication technologies. Positions of states regarding the adoption of resolution in the sphere of international information security were studied through examples of Japan, India, and China. It is proved in the article, that information technologies have become an important component of the security system in the world. Technologies usage may lead to steady international development as well as to information arms race. That is why working out a common position on international information security issues is of crucial importance. It is within the framework of the UN, that different states of the world are given an opportunity to express their visions of the problem of international information security and work out common approaches to its solution. The article shows, that states’ positions have similar as well as different features. For instance, all states express concern regarding possible limitation of technology transfer for the establishment of a more controlled international political environment. But states’ positions have major differences as to mechanisms of information security provision. Thus, Japan and India strive to achieve a balanced system of international information security, which should at the same time have preventive mechanisms against the emergence of threats in the information and science and technology spheres and guarantee continuation of scientific-technological development, which is a crucial component of development and modernization strategies in many countries of the world. China came forward with position of strong regulation of international information security issues and suggested framing of corresponding regulations of the states’ conduct in the cyberspace.

Harsh Reality

‘Privacy, privacy everywhere but not a safety method to implement it’: a harsh reality of today’s world. With the precipitation of more data (2 x 1019 bits of data is created in every 86400 seconds) in computer networks, involvement of meta-data in the form of images is essential. To keep data safe and secure in order to inculcate privacy, to eradicate any kind of eavesdropping, and to maintain confidentiality, integrity and availability of it, certain security measures are needed to make in account for. So in order to make it available, we required a technique through which we can securely transfer any kind of data over a network. In practise the information security can be achieved either by using Cryptography or Steganography. The process described in this paper is not a mediocre it is more scrupulous towards the security because it involves image encryption, steganography and image stitching. Initially we are encrypting an image using Blowfish algorithm then we are embedding the secret text into this encrypted image by modifying the least significant bit (LSB) of the image by our data. Moreover, to enhance the privacy and security we are stitching the above resultant image with the red, green and blue (RGB) components of a host image and thereby producing an image more secure than the one which the existing systems can form for data transmission..

Wireless Visual Sensor Networks

With the continuous improvement of encryption algorithms, some applications based on the architecture of wireless visual sensor networks have gradually shifted their attention to the imperceptibility and antijamming performance of secret images. To reduce the probability of secret images being detected, the current research focuses on hiding secret data in the least-significant bit of the cover image in the spatial domain or embedding data into the coefficients of the high-frequency band in the transformational domain, which usually leads to poor performance in a hostile environment. Therefore, some researchers proposed to substitute the coefficients of the medium-frequency band in the transformational domain with secret information to enhance the anti-interference performance. However, this idea would severely affect the imperceptibility of secret images. As a result, an improved version based on the partial preservation embedding algorithm was designed in this paper. Theory analysis and simulation results indicate that the proposed scheme performs better than the existing methods by directly substituting the coefficients of the medium-frequency band in the transformational domain, especially in the case of strong noise interference.

Information Assurance (IA) is an intensively discussed discipline. Perhaps the most striking feature of IA is that everyone has a different opinion about what it actually is. The literature analysis enables us to distinguish three different approaches to Information Assurance: 1) Technical approach, concentrated on protection of networks; 2) Business approach, where IA is perceived as the comprehensive and systematic management of Information Security (InfoSec); 3) General approach, where IA is considered as a way to establish a level of confidence in information. Interviews with InfoSec practitioners reveal that they interpret the term IA differently and have contradictory views on how IA relates to InfoSec. It was felt that a survey with a greater number of practitioners might help to identify a commonly accepted perception of IA and to clarify the goals of the discipline. In 2011, a survey was conducted among one hundred InfoSec and IA professionals across the world. This chapter presents the results of the survey.

Compliance with regulatory guidelines and mandates surrounding information security and the protection of privacy has been under close scrutiny for some time throughout the world. Smaller organizations have remained “out of the spotlight” and generally do not hire staff with the expertise to fully address issues of compliance. This case study examines a project partnership between an information-technology (IT) consultant who specializes in small business and a diminutive medical practice that sought support with compliance issues surrounding a research study it was conducting. Other small medical practices were contributing to the research; consequently, information sharing while concurrently adhering to the regulations of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 was a significant aspect of the project. It was also critical that numerous other security and privacy legislative requirements were met. The issue of data security is often neglected in IT instruction. This case study provides a foundation for examining aspects of information security from the perspective of the small-business IT consultant.
