Secure Data Transmission 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,

With the development of internet technology, society has been pushed compulsorily into a ‘big data’ period(Craig and Ludloff,2011).”Big data refers to the massive amounts of data collected over time that are difficult to analyze and handle using common database management tools” (http://www.pcmag.com). Not only the development strategy of the government and enterprises, but also threaten citizens’ personal information security. There are significant issues increases rapidly due to this environment such as transfer , reproduction and abuse of personal information. Therefore, it provides convenience to criminal who wants to steal personal information of other people for benefit reason or other reasons. This essay aims to introduce the risks to personal information on the internet and find some solutions to relieve even solve these problems. Firstly, following article will indicate why personal information is risky on the internet and the situation of information security in recent internet environment. Secondly, significant issues from information security will be shown. Finally, solutions and evaluations need to be come up with so that people can protect their privacy.

In a perfect world, the capacity to place material in a World Wide Web (WWW) has pulled in countless. Hence, development of programming applications kills many-sided quality and inconvenience included in composing HTML. This move results to more sites, which are made utilizing humble level of web outline education. Clearly, individuals are gradually grasping the business utilization of web and WWW. This move has raises an extent of issues that remaining parts unsolved. The prickly moral issues incorporate protection, individual data, protected innovation, and digital wrongdoing. Security is an individual case of appreciating free space described by free from reconnaissance or interference. With a wise framework, a great many clients are liable to reconnaissance a move that undermines singular protection. Further, client data, for example, Visa card number goes through an arrangement of stage for confirmation, which triggers attack of protection. Boundless data use triggers responsibility for outcome moral issue. This move is adapted towards shielding institutional qualities and the bigger society. As being what is indicated, Kirby must build up the best component of managing the responsibility issues. Furthermore, the idea of PC wrongdoing data accessibility coming about because of approved access, utilization, adjustment and demolition of

Encryption is a cryptography in which one covers data or information by transforming it into an undecipherable code. Encryption generally uses a predefined parameter or key to perform the data change. Some encryption computations oblige the best approach to be the same length as the message to be encoded yet other encryption counts can take a shot at much more diminutive keys concerning the message. Separating is as often as possible described close by encryption as it’s backwards. Unscrambling of encoded data realizes the first data. Encryption is used as a piece of customary forefront life. Encryption is most used among trades over flimsy channels of correspondence for instance the web. Encryption is also used to secure data being traded between contraptions, for instance, modified teller machines (ATMs), cells, and various more. Encryption can be used to make automated imprints, which allow a message to be affirmed. Exactly when honest to goodness executed, an automated imprint gives the recipient of a message inspiration to acknowledge the message was sent by the affirmed sender. Modernized imprints are outstandingly significant when sending tricky email and distinctive sorts of cutting edge correspondence. This is by and large equivalent to standard composed by hand marks, in that, an all the more astounding imprint passes on a more multifaceted methodology for manufacture. Figure a figure is an estimation, strategy, or method for performing encryption and translating.

but as new technologies arise in combination with the interest of corporations the ability to stay informed is putting at risk another important aspect of life, which is our privacy. We have become increasingly dependent on the internet and its applications to get through our days, to find the information we need, to store and send information, as well as, for entertainment.

This critical review is to investigate steganographic studies and their methods to either exfiltrate data or defend against data exfiltration. Steganography has one main purpose, to conceal data. Huang’s (2011) method, embedding steganographic data in inactive frames of low-bit rate audio streams went against the norm (Aoki, 2008), (Wu et al., 2006), used active frames of high-bit rate audio streams. Active high-bit rate audio streams have higher least significant bit counts, which presents added frames to conceal steganographic payloads (Huang et al., 2011). Howbeit, Huang (2011) demonstrated a new algorithm he administered to (VOIP) inactive frames of low-bit audio streams, which could carry higher capacity payloads than

The concept of securing the messages through cryptography has a long history. The word cryptography stems from the two Greek words “crypto” and “grafein” meaning “hidden” and “write” respectively. Julius Caesar is credited with creating one of the earliest methods of cryptography system to send the message to his generals.

Information is a valuable asset for businesses and organizations. Advances in information technology facilities the storing, transferring, and modifying of data. Organizations use information technologies such as the Internet and networked technology to reduce operating costs, improve customer service, and improve productivity. However, Using the Internet has increased the number of frontier that must be protected and has bought a lot of concerns about security issues. (Ezingeard, McFadzean, & Birchall, 2005)

Various methods of hiding information have been used for centuries; but it has always been an issue of how to get the information to the designated individual securely without being intercepted or compromised. With the use of cryptography and encryption the information being delivered could be obscured so message preventing the message from being read in the event the message was able to be intercepted; to be able to read the message the receiving party would only be able to decipher the message using the corresponding decryption algorithm. The use of steganography or covert channels individuals could easily transmit information without anyone ever discovering the existence of hidden information; since it could

Symmetric encryption is the earliest and widely popular encryption technique. This technique uses a secret key which can be a string of words, numbers which are randomly selected to effect confidentiality. The secret Key is applied on the original message to change the content into a cipher. The modification of the message to the cipher might be a simple reordering of the message letter sequence to complex alterations. With the help of the secret key the sender and the recipient can encrypt and decrypt messages respectively.

Steganography is an ulterior, and lesser-known approach to private communication. Steganographic applications work by taking in three things: a cover work; this could be a picture, an audio file, a video file, etc., a message to be embedded, and a stego key; we don’t always use one but if we do it is much like an encryption key. Steganography applications will then embed the message into the cover work. This is most commonly performed using a method known as LSB embedding, which I will explain in detail.

Cryptography and Steganography is too used to secure communication. According to dictionary.com: Steganography is: “Hiding a secret message within a larger one in such a way that others cannot discern the presence or contents of the hidden message” and Cryptography is “The process or skill of communicating in, or deciphering secret writing or ciphers [2].”

Moreover, it is feasible to utilize the relation between two or more different network protocols to enable secret communication. These applications fall under the term inter-protocol steganography. [34]

Abstract—Problem confronted by today 's communicators is security as well as the pace of correspondence and size of substance. In the present paper, a plan has been proposed which utilizes the idea of pressure and information encryption. In first stage th center has been made on information pressure and cryptography. In the following stage we have underscored on pressure cryptosystem. At long last, proposed procedure has been examined which utilized the idea of information pressure and encryption. In this first information is compacted to diminish the measure of the information and expansion the information transferrate. There after compress data is encrypted to give security. Consequently our proposed system is powerful that can decrease information size, build information exchange rate and give the security amid correspondence.

As no of patients that are suffering from cardiac diseases are increasing very rapidly, it is important that remote ECG patient monitoring systems should be used as point-of-care (PoC) applications in hospitals around the world. Therefore, huge amount of ECG signal collected by body sensor networks from remote patients at homes will be transmitted along with other personal biological readings such as blood pressure, temperature, glucose level, etc., and get treated accordingly by those remote patient monitoring systems. It is very important that patient privacy is protected while data are being transmitted over the public network as well as when they are stored in hospital servers . In this paper, a one new technique has been introduced which is the hybrid of encryption and wavelet-based ECG steganography technique . Encryption allows privacy and ECG steganography allows to hide one sensitive data into other insensitive host thus guaranteeing the integration between ECG and the rest.
