Steganography is a technique hiding secret information within innocent-looking information (e.g., text, audio, image, video, and so on). In this paper, we propose a quantum steganography protocol using plain text as innocent-looking information called cover data. Our steganograpy protocol has three features. First, we can use any plain text that is independent of any secret message sent between...

In this paper, a security model is proposed which imposes the concept of secrecy over privacy for text messages. In the recent years, we have plenty of security tools which are developed to protect the transmission of multimedia objects. But approaches for the security of text messages are comparatively less. The model proposed by us combines cryptography, steganography (taken as security layer...

Steganography is the art or practice of concealing a message, image, or file within another message, image, or file. In steganography, there is a technique in which the least significant bit is modified to hide the secret message, known as the least significant bit (LSB) steganography. Least significant bit matching images are still not well detected, especially, at low embedding rate. In this ...

Cryptography, or the use of code, has a sinister relative called steganography. Steganography is supposed to offer confidentiality whereas encryption said provide privacy. A method concealed communication The process steganography involves hiding message in suitable carrier, such as an image audio file, which can then be transported receiver without anybody being aware that it contains hidden m...

Confidential data maintained by Security sources has always been a substantial aspect of hampering unintended access. Technology is enhancing day towards information, especially in terms multimedia file transmission. Combining cryptography and steganography, crossover approach serves information security. Cryptography strategy for changing over from plain content Cipher Text. Steganography the ...

Steganography is the science of hiding a message signal in a host signal, without any perceptual distortion of the host signal. Using steganography, information can be hidden in the carrier items such as images, videos, sounds files, text files, while performing data transmission. In image steganography field, it is a major concern of the researchers how to improve the capacity of hidden data i...
