Different security strategies have been developed to protect the transfer of information between users. This has become especially important after the tremendous growth of internet use. Encryption techniques convert readable data into a ciphered form. Other techniques hide the message in another file, and some powerful techniques combine hiding and encryption concepts. In this paper, a new security algorithm is presented by using Steganography over HTML pages. Hiding the information inside Html page code comments and employing encryption, can enhance the possibility to discover the hidden data. The proposed algorithm applies some statistical concepts to create a frequency array to determine the occurrence frequency of each character. The encryption step depends on two simple logical operations to change the data form to increase the complexity of the hiding process. The last step is to embed the encrypted data as comments inside the HTML page. This new algorithm comes with many adva...

Steganography can be defined as the art or science of hiding information in cover media for the purpose of making it secrete information. There are many techniques used in steganography like image steganography, audio steganography and text steganography. In this paper we are going to explore an effective technique to hide encrypted text in HTML document, HTML is language regarded as the standard publishing language of the World Wide Web and it can process both plain and format text within it. We were used two that contains two processes and implemented by C#. Firstly is to encrypt the text file using one of the most efficient of encryption algorithms, the AES algorithm, and then to hide encrypted data in HTML document. And the other one is to extract the encrypted secrete file from the HTML webpage and then to decrypt the extracted file using the same key and method of the first algorithm. In order to make secrete message undetectable and more reliable encryption technique where used, encryption form of the text gives the secrete data extra layer of security, encryption gains its roots from cryptography. Cryptography means or it is the study of converting format of the text (the secrete data/information) in to another non-readable form to hide the real message from third part.
Cryptography, Steganography and Watermarking are three rudimentary techniques which will avail us to secure data from unauthorized access. Steganography is one of the best techniques to obnubilate message from unauthorized users. It is utilized to obnubilate data through sundry medium like audio, video, Text and image. In our research work, we fixate on text Steganography through html web pages to obnubilate data behind it. Because html pages are facilely transferable that contains secret data behind it. There are sundry methods of web pages predicated Steganography. Some of the mundane methods are white spaces, order of attributes, change case letter, change quotation marks, reiterate attributes to obnubilate data etc. But these all methods have some inhibition like iota of data can be obnubilated behind html page & do not have most sizably voluminous embedding capacity etc. To surmount or enhance these circumscriptions we optate to apply any compression technique afore embedding process so that it can obnubilate substantial amount of data and secondly security is much more consequential thus we have to apply any encryption techniques so that data cannot transferable in its pristine form. Thus in our research work we fixates on embedding techniques, compression and encryption techniques. So that system will be more power full as well as secure.
The art of hiding sensitive information within an object in a manner that the existence of that information remains oblivious to an observer is known as Steganography. Together with today's ubiquitous computing systems, Steganography has evolved into a science which offers a variety of methods for stealth communication across the globe. The framework for elucidating a text in a way that is grammatically distinguishable from its content is called a markup language. In this regard, the course of action is communicated explicitly by typifying it through labels or tags. The objective of this study, however, is to encapsulate the fundamental concepts of steganography with the recent research trends for Hyper Text Markup Language document within a single confine. Analyze it from a security aspect, and present the research findings which may serve as an idiosyncratic source of information to facilitate such futuristic research. Another contribution of this study is in demarcating the difference between secrecy and security while discussing the evaluation criteria for steganographic systems. This study also intends to implicitly propagate the awareness that the intent of any steganographic scheme should remain to compel an intruder to commit the false negative type of errors.

Abstract- In the world of information technology security of data is most important part. Everywhere there is a problem of security threats which are always looking to steal the information. So any how data protection is required. Cryptography, steganography and watermarking are some of the well known data protection techniques. Steganography and cryptography are data hiding techniques while watermarking is used to give unique identity to the objects like image, audio, video etc which prevents it from forgery. The benefit of steganography over cryptography is that no one except sender and intended user can see the message. This survey paper concentrates on the steganography techniques and mainly on the techniques that have used web document as a carrier to hide the data. The HTML steganography has its own benefit that data doesn’t look suspicious because HTML web pages are fundamental elements of the modern internet technology and are very rapidly used in websites.

–With the rapid growth of networking mechanisms, where large amount of data can be transferred between users over different media, the necessity of secure systems to maintain data privacy increases significantly. Different techniques have been introduced to encrypt data during the transfer process to avoid any kind of attack. One of these techniques is to hide the data inside another file which is called Steganography. In steganography, data is hidden inside a carrier file where anyone can see, but the hidden data inside it cannot be discovered. To this end, good algorithms can avoid the suspicion of having any attacker by applying some criteria before sending the data. In this paper, we present an algorithm to hide data using a text file as a carrier. Left-Right Remarks that represent Unicode symbols are used to hide the data inside the text file. Moreover, our algorithm can be applied in different size textual data.
