Hiding Secret Data Using Image Steganography

2015

Steganography is the science of hiding the fact that communication is taking place, by hiding information behind information. Many different carrier file formats can be used, but digital media are the most popular because of their usage on the Internet. For hiding secret information in digital media, there exists a large variety of steganography techniques some are more complex than others and all of them have some advantages and disadvantage. Various applications have different requirements of the steganography technique used. For example, some applications may require absolute invisibility of the secret data, while others require a larger secret data to be hidden. This paper intends to give an overview of Digital media steganography, its uses and techniques. It also attempts to identify the requirements of a good steganography algorithm and briefly reflects on which stenographic techniques are more suitable for which applications.

Abstract— Digital communication has become an essential part of infrastructure nowadays, a lot of applications are Internet-based and it is important that communication be made secret. As a result, the security of information passed over an open channel has become a fundamental issue and therefore, the confidentially and data integrity are required to protect against unauthorized access and use. This has resulted in an unstable growth in the field of information hiding. In a modern era of Information Technology, illicit copying and illegal distribution accompany the adoption of widespread electronic distribution of copyrighted material. This is the main reason why people think about how to protect their work and how to prevent such unlawful activities. For this purpose various methods including cryptography, steganography, Digital signature, coding and so on have been used. Steganography is the best suited technique that allow user to hide a message in another message (cover media). Most of steganography research uses cover media as pictures, video clips, text and sounds. This paper focuses on the various techniques in steganography to enhance the security of communication over an open channel.

Steganography is a art of communicating by hiding a type of information in other information.In the present era, the more attention is given to the art of displaying and sending hidden information because of security purpose.Therefore, different methods have been proposed so far for hiding information in different cover media. In this review paper, we are highlights the various study and research done before.Steganography's primary goal is to hide data within some other data such that the hidden data cannot be detected even if it is being sought.A lot of researchers has done tremendous work in this art but there is lack of a single means to concrete all the information in single study.This paper aims to fulfill that dearth.

The goal of steganography is to insert a message into a carrier signal so that it cannot be detected by unintended recipients. Due to their widespread use and availability of bits that can be changed without perceptible damage of the original signal images, video, and audio are widespread carrier media. Steganalysis attempts to discover hidden signals in suspected carriers or at the least detect which media contain hidden signals. Therefore, an important consideration in steganography is how robust to detection is a particular technique. We review the existing steganography and steganalysis techniques and discuss their limitations and some possible research directions.

Cryptography, or the use of code, has a sinister relative called steganography. Steganography is supposed to offer confidentiality whereas encryption is said to provide privacy. A method of concealed communication is steganography. The process of steganography involves hiding a message in a suitable carrier, such as an image or audio file, which can then be transported to the receiver without anybody being aware that it contains a hidden message. This is a method that civil rights organizations in oppressive states, for instance, might utilize to propagate their message without the knowledge of their own government. This paper aims to discuss different techniques for implementing steganography to multimedia files (text, still images, audio, and video).

Nowadays, the volume of data shared over the Internet is growing. As a result, data security is referred to as a major issue while processing data communications through the Internet. During communication procedures, everyone requires their data to remain secure. Steganography is the science and art of embedding audio, message, video, or image into another audio, image, video, or message to conceal it. It is used to secure confidential information from harmful attacks. This research offers a classification of digital steganography based on cover object categories, as well as a classification of steganalysis art. Image visual quality, structural similarity, mean square error, Image Fidelity, embedding capacity, and robustness are some of the important aspects of steganography. Researchers have made tremendous advances in the realm of digital steganography. Nonetheless, it is vital to emphasize the advantages and disadvantages of modern steganography techniques. This paper first presents a literature survey of information hiding, then classifies the proposed methods, and finally introduces a comparative study between the different methods.

With the explosive growth of internet and the fast communication techniques in recent years the security and the confidentiality of the sensitive data has become of prime and supreme importance and concern. To protect this data from unauthorized access and tampering various methods for data hiding like cryptography, hashing, authentication have been developed and are in practice today. In this paper we will be discussing one such data hiding technique called Steganography. Stegnography is the process of concealing sensitive information in any media to transfer it securely over the underlying unreliable and unsecured communication network. Our paper presents a survey on various data hiding techniques in steganography that are in practice today along with the comparative analysis of these techniques. Data hiding, a form of steganography, embeds data into digital media for the purpose of identification, annotation, and copyright. Several constraints affect this process: the quantity of...

The innovation of technology and having fast internet make information to distribute over the planet easily and economically. this is often made people worry about privacy and works. Steganography may be a technique that forestalls unauthorized users to possess access to big data. The steganography provides methods that users can hide and blend their information with other information that make them difficult to acknowledge by attackers. In this, we review some techniques of steganography spatial and frequency domains. Also, we explain the kinds of steganography host documents. It also can pose serious problems due to it difficult to detect. Network surveillance and monitoring systems won't flag messages or files that contain steganographic data. and that we also see some applications, pros, and cons of steganography.

Steganography and cryptography are cousins in the spycraft family. Cryptography scrambles a message so it cannot be understood. Steganography hides the message so it cannot be seen. A message in ciphertext, for instance, might arouse suspicion on the part of the recipient while an “invisible” message created with steganographic methods will not. In this article we discuss image files and how to hide information in them, and we discuss results obtained from evaluating available steganographic software.

Steganography is going to gain its importance due to the exponential growth and secret communication of potential computer users over the internet [5]. It can also be defined as the study of invisible communication that usually deals with the ways of hiding the existence of the communicated message. Generally data embedding is achieved in communication, image, text, voice or multimedia content for copyright, military communication, authentication and many other purposes [2]. In image Steganography, secret communication is achieved to embed a message into cover image (used as the carrier to embed message into) and generate a stego- image (generated image which is carrying a hidden message)[1]. In this paper we have critically analyzed various steganographic techniques and also have covered steganography overview its major types, classification, applications [3].

Steganography, literally meaning “secret writing”, involves hiding a data file in another innocuous-looking file. From the time of Herodotus in Greece, to the defense mechanisms of today, steganography has been used to deny one’s adversaries the knowledge of message traffic. Steganography takes one piece of information and hides it within another. A “container file” holds the secret message in it, in such a way that the existence of the message cannot be suspected. This could be done in several possible ways, with newer methods being discovered with each passing day. In this paper, a detailed analysis of steganography is made. The history of steganography is briefly dealt with. How steganography works is examined, keeping in mind Bender’s specifications. Data hiding is implemented in three different media; text, audio and image files. Each offers challenges and solutions to these challenges are analysed. How they is implemented using steganographic tools is also seen. The main chara...

Visual secret sharing (VSS) systems hide hidden images in shares that are also published on clarity or decrypted and saved in digital form. The shares can seem as noise-like pixels or as meaningful images, but this will raise suspicion and increase the risk of interception during transmission. As a result, VSS schemes face a transmission danger problem for both the secret and the individuals involved in the VSS system. To solve this issue, we presented a new palette-grounded steganography technique that uses a texture with LSB, as well as a natural-image-grounded VSS scheme (NVSS scheme) that shares secret images via colored carrier media to hide the secret and the actors during the transmission phase. To conceal secret messages, we convert the texture conflation process into steganography. Rather than using a being cover image to conceal dispatches, our algorithm conceals the source texture image and embeds hidden dispatches during the printing process. Prints or hand-painted filmland in digital or published form can be used for the natural shares. We also propose possible methods for concealing the secret in order to reduce the transmission threat problem for the share. The experimental results show that the proposed approach is an excellent solution to the transmission threat problem for VSS schemes.
