Image Security Case Study

With the rapid development of computer technologies and internet, one can get any information through internet very easily. To transfer or convey a message from one point to another is also very convenient in today’s era. People who have internet and computer can get any type of information related to any field without any difficulty [1]. While transferring or communicating on internet safety and security remains an issue. Steganography schemes are used to get rid of these type of safety and security issues. The standard phrase “What You See Is What You Get (WYSIWYG)” is not true if the misuse or hacking is there. One can transfer secret information through internet using Steganography

Steganography in the context of digital content piracy serves primarily as a method to track where digital assets are moving or who is receiving them. It can be a good solution for distribution of a small number of copies but becomes less effective when distributing on a wide basis. In order for it to be effective a content provider needs to recover the content by means of the unauthorized channel and examine the indicator marked on the copy. This is cumbersome for wide distribution but can be used on a broad basis such as by region. Region coding is used with many DVD releases for example but can also be considered a type of DRM (Andrew,

Multimedia content is also in collaboration with Encryption & Decryption standards (CBR).The below paper is the general

Information security is a major concept in today’s industrial and computer era, so security must be higher to protect the confidential data. Information security plays major role in computer and network security with the use of different cryptography algorithms that includes the encryption and decryption of data with the uses of the algorithm and the key. By means of text or numerical key for the encryption can be dangerous because with the several hack attacks that a key can be broken. So I have proposed a new mechanism that will replace the text key with the image pixels and can gain high security which cannot be easy to break without prior knowledge.

Typical network steganography methods involve modification of the properties of a single network protocol. Such modification can be applied to the PDU (Protocol Data Unit), [29][30][31] to the time relations between the exchanged PDUs,[32] or both (hybrid methods).[33]

The United States has held serious tension with monopolies and overarching, powerful companies since before the Boston Tea Party. They are some of the most illicit phenomena known to Americans, which has led to its governmental regulation. Nevertheless, Americans have found a near-enough equivalent: oligopolies; the formation of very few, large companies dominating their respective sectors through what is recognized as the concept of “corporate consolidation”. This process involves eliminating the competition by essentially purchasing it, maintaining only a few potent, growing, businesses in the market (Wu). Found in any type of industry, the pairing of the power these

According to identitytheft.info, almost 15 million Americans have their identity used fraudulently due to information leaks and information insecurities. With the growing dependency on computer systems to store confidential information across the world, it is only necessary that that the information be protected by strong security systems which include both hardware and software so that both the businesses and the consumers feel safe in the transportation of information over the inter-webs. Contemporary Information security systems use many different components involving both hardware and software

For the purpose of this paper, I will be focusing on Steganography, which I believe is the most efficient part of steganography. Unlike other Information hiding methods where the encryption is usually detectable, steganography takes it further by hiding the message within mediums like images, main it almost impossible to detect. The purpose of this paper is to explain Steganography, how it works compared to other methods and show methods of application and types of steganography.

In this modern era, the computer and internet have becomes the most effective and fastest media for communication that connect different parts of the global world. As a result, people can easily exchange information and share information with the others via the internet. However, the information security requires the confidential data that needs to be protected from the unauthorized users. Steganography is one of the methods used for the secure transmission of confidential information. It can provide a high level of security to secure the important data during combined with encryption.

Steganography has been around since 1980’s. Various tools and software’s are available for Steganography as well as Steganalysis. The most common form of steganography is on digital images. For digital images there exist many steganographic techniques and furthermore there exist a lot of approaches to detect steganography in digital images. In this paper we will be looking at many tools comprising from various digital domains but we fund that almost all of the tools had support for image files. With the increasing number of new steganographic algorithms and methods for detecting steganography, the issue of comparing security of steganographic schemes in a fair manner is of the most importance. A fair benchmark for steganography should only

Whether a person is an occasional computer user, works in a major corporation, or within a government agency there is a dangerous risk out there. That risk is one that everyone must be concerned with, inadequate computer security. Computer security has become essential in today’s well connected digital world. Everyone wants to communicate with someone at sometime; and normally these communications need to be secure. Whether the information is traveling around the world or just across the room to another computer, this information is at risk. Safeguards must be implemented to the computers and networks that they use to protect them from viruses, intruders, and system failures.

The concept of data security is not new to anyone. It refers to those technologies which have been discovered so as to keep the important data safe and out of reach from anyone undesirable. This has been done so as to keep the data safe from any intruders who could get into the computer system through hacking. As a result of advancements in the field of information technology, most data is kept on desktops or in the clouds. With the help of such techniques, any unauthorized person could be kept out of a personal computer so that no one has access to any important data. Apart from stealing important data, there is also a chance that any data could be forged and changed so as to affect the authenticity of available information (Berman, 2016). This could not only affect organizations but also individuals since the stolen or modified data could be important for them. For this purpose, the name data or information security came into existence. This branch of computer sciences started with the emergence of needing to keep data safe. The concept has been shoot and miss in areas of success in keeping data away from prying eyes. However, there have been some cases as to where security did not work. In this paper, I will examine the case between Apple and the Federal Bureau of Investigations.

Mobasseri presented the method of a message either encrypted or unencrypted, can be hidden in a computer video file (containing the picture of, for instance, an innocent 2 year old baby) and transmitted over the Internet, a CD or DVD, or any other medium [5].Shiguo lian provide the main goal of steganography is to communicate securely in a completely undetectable manner and to avoid drawing suspicion to the transmission of a hidden data [4]. III. PROPOSED WORK A. Video Compression Video compression uses modern coding techniques to reduce redundancy in video data. Video compression typically operates on square-shaped groups of neighboring pixels, often called macro blocks. These pixel groups or blocks of pixels are compared from one frame to the next and the video compression code sends only the differences within those blocks.

Abstract—Video data hiding is still an important research topic due to the design complexities involved. We propose a new video data hiding method that makes use of erasure correction capa- bility of repeat accumulate codes and superiority of forbidden zone data hiding. Selective embedding is utilized in the proposed method to determine host signal samples suitable for data hiding. This method also contains a temporal synchronization scheme in order to withstand frame drop

DIGITAL image watermarking has become a necessity in many applications such as data authentication, broadcast monitoring on the Internet and ownership identification. Various watermarking schemes have been proposed to protect the copyright information. There are three indispensable, yet contrasting requirements for a
