A Novel Image Steganography Technique based on Similarity of Bits Pairs
Authors:
Publisher and Date:(IEEE, 2017)Steganography is one of the most important information hiding mechanism which can be used along with cryptography for providing adequate data security. The common Steganographic mediums used are text image audio and video for hiding secret information. In the case of image medium mostly least significant bits of pixels of a cover image are used for hiding secret information. In this paper a new technique based on pairs matching is proposed data bits of the message to be secured are arranged in ...

Developing novel techniques for spatial domain LSB i̇mage steganography
Authors:
Publisher and Date:(Kadir Has University, 2019)Steganography is one of the most noteworthy information hiding mechanism, which is used as an alternative to cryptography in order to provide adequate data security. Image steganography is one of the key types of steganography where a message to be transmitted is hidden inside a cover image. The most commonly used techniques for image steganography rely on LSB Steganography. In this thesis, new techniques are developed for LSB image steganography to achieve maximum security, optimal data capacity ...

Performance Improvement of Threshold Based Audio Steganography Using Parallel Computation
Authors:
Publisher and Date:(Science & Information SAI Organization Ltd, 2016)Audio steganography is used to hide secret information inside audio signal for the secure and reliable transfer of information. Various steganography techniques have been proposed and implemented to ensure adequate security level. The existing techniques either focus on the payload or security but none of them has ensured both security and payload at same time. Data Dependency in existing solution was reluctant for the execution of steganography mechanism serially. The audio data and secret data ...
