Encrypted messages sending frequently draws the attention of third parties, perhaps causing attempts to break and reveal the original messages. Steganography is introduced to hide the existence of the communication by concealing a secret message in an appropriate carrier like text, image, audio or video. Steganography is of Greek origin and means "Covered or hidden writing". The carrier can be ...

This paper describes a method for checking the acceptability of paraphrases in context. We use the Google n-gram data and a CCG parser to certify the paraphrasing grammaticality and fluency. We collect a corpus of human judgements to evaluate our system. The ultimate goal of our work is to integrate text paraphrasing into a Linguistic Steganography system, by using paraphrases to hide informati...

Steganography and cryptography are used to send the data in a confidential way. Steganography hides the existing message and cryptography will confuse the message. The transformation of plain text to cipher text is called as encryption. The transformation of cipher text to plain text is called decryption. Encryption and decryption are controlled by keys. Hashing, symmetric and asymmetric algori...

Different strategies were introduced in the literature to protect data. Some techniques change the data form while other techniques hide the data inside another file. Steganography techniques conceal information inside different digital media like image, audio, and text files. Most of the introduced techniques use software implementations to embed secret data inside the carrier file. This is wh...

Design and Implementation of Steganography along with secured message services in Mobile Phones is used to provide security to the data that flows across the mobiles. Two people may communicate securely by encrypting the message sent between them. Now a day, several methods are used for communicating secret messages for defense purpose or in order to ensure the privacy of communication between ...

Steganography is one of the methods of secret communication that hides the existence of hidden message. It can be defined as the study of invisible communication that usually deals with the ways of hiding the existence of the communicated message. The hidden message may be text, image, audio, video, etc. The files can be a cover image after inserting the message into the cover image using a ste...

Today, secure communication is the need of the society. Steganography and Cryptography are most popular techniques used for secure communication in the present era. Steganography is used hide the existence of data within some cover media like image file, audio file, video file, text file etc. But the most commonly used media for steganography is image file. There are many techniques of image st...

In today’s world, there are a number of cryptographic and steganography techniques used in order to have secured data transfer between a sender and a receiver. In this paper a new hybrid approach that integrates the merits of cryptography and audio steganography is presented. First, the original message is encrypted using chaotic neural network and the resultant cipher text is embedded into a c...

With the rapid development of Internet, safe covert communications in the network environment become an essential research direction. Steganography is a significant means that secret information is embedded into cover data imperceptibly for transmission, so that information cannot be easily aware by others. Text Steganography is low in redundancy and related to natural language rules these lead...
