“…In [29], authors proposed new strategy employs RSA algorithm with 128-byte key size for encrypting the secret information before embedded it into a cover image and use F5 steganographic algorithm to embed the encrypted message in the cover image gradually. they selected chosen Discrete Courier Transform (DCT) coefficients randomly to embed the secret message into it by using F5 algorithm.…”

Digital communication witnesses a noticeable and continuous development in many applications in the Internet. Hence, secure communication sessions must be provided. The security of data transmitted across a global network has turned into a key factor on the network performance measures. So, the confidentiality and the integrity of data are needed to prevent eavesdroppers from accessing and using transmitted data. Steganography and Cryptography are two important techniques that are used to provide network security. In this paper, we survey a number of methods combining cryptography and steganography techniques in one system. Moreover, we present some differences between cryptography and steganography. The aim of this paper is to develop a new approach to hiding a secret information in an image or audio or video, by taking advantage of benefits of combining cryptography and steganography. In this method first, the message is encrypted by using AES algorithm and hashed the key using SHA-2 to prevent from attacks. After that, we performed some modifications on LSB algorithm by adding a key to make hiding process non sequential. Results achieved indicate that our proposed method is encouraging in terms of robustness and security.

Encryption is the method by which we can encode the intended piece of information in such a way that only the people whom we want to pass that information can understand its actual meaning. Digital Image Steganography the message is hidden in an image in such a way that the onlookers cannot even guess that it is not a normal image. Nowadays security is a vital issue while transmitting a message. So in this paper we have proposed a unique way of transmitting the message securely. First we have encrypted the message to an image which needs a secret key to be decrypted. Then we have hidden that image inside another image by steganographic approach. By thistwo level hiding we can ensure stronger security.

“…A supposition may be completed based on this typical when both the sender and receiver will share particular public secret data then the conforming steganography procedure is recognized as then the secret key steganography where as pure steganography proceeds that there is nothing previous data mutual by sender and receiver. While the public key of the receiver is identified to the sender, the steganographic procedure is named public key steganography [10].…”

Steganography can be defined as the art and science of hiding information in the data that could be read by computer. This science cannot recognize stego-cover and the original one whether by eye or by computer when seeing the statistical samples. This paper presents a new method to hide text in text characters. The systematic method uses the structure of invisible character to hide and extract secret texts. The creation of secret message comprises four main stages such using the letter from the original message, selecting the suitable cover text, dividing the cover text into blocks, hiding the secret text using the invisible character and comparing the cover-text and stego-object. This study uses an invisible character (white space) position of in the cover text that used to hide the the secrete sender masseges. The experiments results show that the suggested method presents highly secret due to use the multi-level of complexity to avoid the attackers.
