“…In [17], the authors suggested a hybrid technique to secure the secret data that use the behaviors of steganography (LSB, raster scan technique) and cryptography (symmetric key). Using a symmetric key cryptography technique, which is contentbased and uses the block cypher principles, the secret text will first be encrypted, but the size of the block in this technique is not determined, depending on the length of the term (word).…”

Data exchange has been significantly encouraged by the development of communication technology and the wide use of social media over the Internet. Therefore, it is important to hide the data transmitted, especially the data that requires a person's signature. Where the signature is an increasingly needed item that is used in our daily life to achieve some paperbased authentication in departments, the individual himself needs the signature. Cryptography and steganography are commonly considered to be the most important data hiding methodologies. Steganography is used to hide the secret message in the carrier media, such as text, audio, video, and image files, without the carrier media being distorted, and cryptography is used to conceal the purpose of the secret message. A hybrid data hiding (image steganography) and encryption technique is implemented in this research on the time domain. The secret handwritten signature image is first encrypted using the public key algorithm (RSA) in the proposed technique, then randomly inserted using Embedding data process to be concealed in one of the last three bits of that pixel(1 st Least Significant Bit, 2 nd LSB, and 3 rd LSB) based on mathematical randomized formula over all pixels of the carrier media (image). It is assumed that the process of randomization will increase the protection provided by the technique. The suggested technique is implemented on gray level cover images. As a consequence of the random scattering of bits and using encryption, it is noted that the proposed technique achieves enhanced data hiding results in terms of performance, protection, and imperceptibility properties and the histogram of the proposed technique is better and provides more protection and security than the ordinary sequential Least Significant Bit (LSB).

“…Here the system is upgraded to enhance the security of data in cloud [2].The method proposes here uses mixture of cryptography and image steganography. The cryptographic method used for encrypting the confidential message is based on content encryption algorithm and the techniques which are used for steganography are LSB and raster scan techniques [3].The paper shows multiple terminologies used for the technique and problem associated with the security. The paper has taxonomy for the published techniques, which focus on techniques of Cryptography and Steganography as well as Combined Cryptography and Steganography Techniques [4].The work in this paper shows two level of security on data.…”

One of the major advantage of cloud computing is that data can be shared among various organizations. However, this advantage itself have a risk to data. In order to negate potential risk to the data, it is necessary to protect data. Encryption is a hugely important tool when it comes to protecting data. This paper propose a new era of cryptographic dual layer encryption to make the data store in cloud more secure and trustworthy. There are readily available many multiple encryption techniques that are available in present time but unable to provide sufficient security. This paper aim to suggest the new encryption technique named as dual encryption. It is based on popular encryption algorithm AES which is symmetric-key algorithm. We are going to propose an additional layer of rabbit algorithm around encrypted data which will help to provide more security against Bruteforce and other type of attacks. Therefore, if an intruder detects a single key of cryptosystem even then it is not possible to decrypt the original message. This paper aims to suggest a perspective which is a double layer encryption method to ensure security in cloud. In this proposed double layers encryption schemes, the data will be extremely secured while protecting and sharing in cloud environment. This scheme not only makes full use of the great processing skill of cloud computing but also can efficiently ensure cloud data privacy and security. I.

Cryptography is both a science and an art to keep the message confidential. While steganography is the science and art of hiding secret messages in other messages so that the existence of such secret messages is unknowable and generally serves to disguise the existence of confidential data making it difficult to detect and protect the copyright of a product. Steganography requires two properties, namely container media and secret messages. The application of steganographic and cryptographic combination is done by Least Significant Bit (LSB) and ROT13 algorithm. Steganography with the LSB method is one of the methods used to hide messages on digital media by inserting it to the lowest bits or the most right bits of the pixel data that compile the file. In this research, the authors propose the technique of securing Steganography secret messages with layered security, by adding Cryptography to secret messages that will be inserted into digital images and then messages inserted into digital images through Steganography using LSB method.
