Today’s internet applications require data to be transmitted in a secure manner. Data transmission in public communication system is not secure because of interception and improper manipulation by eavesdropper. So the solution for this problem is Steganography. That has to do with secure data transmission between a sender and a receiver; implementing Steganography is the best way. Steganography...

Nowadays, information is rapidly available through the Internet. Companies have the ability to communicate with a worldwide audience through the World Wide Web. So Information hiding techniques are received increasing attention due to: the availability of multimedia and digital form objects. And the need to present solutions to criminal copying and copyright problems. In this paper, a new encry...

Steganography refers to the technique of hiding secret messages into media such as text, audio, image and video without any suspicion, while steganalysis is the art and science of detection of the presence of steganography. Steganography can be used for the benefit of the mankind to serve us as well as by terrorists and criminals for malicious purposes. Both steganography and steganalysis have ...

In this paper encryption and steganography algorithms are implemented using JAVATM with android platform to provide the security for real time multimedia messaging service system. Establishing hidden communication for mobile has become an important subject of security. One of the methods to provide security is steganography. Steganography is used to hide secret information inside some carrier. ...

A brief survey of some representative techniques of steganography and steganalysis is presented. Various methods developed in the authors’ laboratory are introduced, including symmetric LSB embedding, secure steganography in JPEG, palette, and uncompressed color images, histogram-based analysis and least histogram abnormality steganography, multiple-base notational system based embedding, stego...

Steganography is the powerful tool for hiding information inside useful cover medium in ways such that the hidden message is undetectable. In Greek language, stego means covered or secret and graphy means to write. Hence, steganography means covered writing. Transform domain steganography is one of the techniques used for hidden exchange of information in frequency domain and it can be defined ...

The overwhelming growth in communication technology and usage of public domain channels (i.e. Internet) has greatly facilitated transfer of data. However, such open communication channels have greater vulnerability to security threats causing unauthorized information access. Steganography is the art of hiding and transmitting data through apparently innocuous carriers such as text, image, audio...

we propose a modified collage steganography using the modified fuzzy c-means algorithm on images. It consists of object images and cover image. Object image consists of the secret message which is to be embedded on the cover image. A proper cover image has to be chose based on the prior analysis. The fuzzy based approach has been formulated for each object image which is to be placed on cover i...

In the modern technological world, where data or image transfer through the internet has gained utmost importance, security of the data has become a major issue. We use cryptography for the security of the above mentioned data. By the help of cryptography, we convert plain text into cipher text, or data that is unreadable to the attacker. Another approach is to hide data in image and then send ...

----------------------------------------------------------------------ABSTRACT----------------------------------------------------------In the recent trend steganography plays an important role in providing secrecy in internet. Steganography works by replacing bits of useless or unused data in regular computer files with bits of different, invisible information. Cryptography is used to scramble...
