Cloud Computing has made it possible to provide individuals as well as organizations with a utility that is costeffective. It empowers businesses by delivering these services using the internet. Files can be shared through the cloud. These files may contain sensitive information that needs to be kept hidden from anonymous users. This is done using cryptographic algorithms. High level of security can be provided using hybrid cryptography to encrypt the data. Advanced Encryption Standard (AES) and Triple Data Encryption Standard (3DES) are the symmetric key encryption algorithms used to secure. An asymmetric key encryption algorithm, Rivest-Shamir-Adleman (RSA) helps in providing a hybrid cryptography model. The security of the key generated can be further enhanced using image steganography method Least Significant Bit (LSB). These issues regarding the security and its challenges will be addressed in this paper and also analyse the measures to handle it.

Lsb Substitution

This study proposes a new hybrid n-LSB (Least Significant Bit) substitution-based image steganography method in the spatial plane. The previously proposed n-LSB substitution method by authors of this paper is combined with the Rivest-Shamir-Adleman (RSA), RC5, and Data Encryption Standard (DES) encryption algorithms to improve the security of the steganography, which is one of the requirements of steganography, and the Lempel-Ziv-Welch (LZW), Arithmetic and Deflate lossless compression algorithms to increase the secret message capacity. Also, embedding was done randomly using a logistic map-based chaos generator to increase the security more. The classical n-LSB substitution method and the proposed hybrid approaches based on the previously proposed n-LSB were implemented using different secret messages and cover images. When the results were examined, it has been seen that the proposed hybrid n-LSB approach showed improvement in all three criteria of steganography. The proposed hybrid approach that consists of previously proposed n-LSB, RSA, Deflate, and the logistic map had the best results regarding capacity, security, and imperceptibility.

Require Data

Current information can be delivered quickly without knowing the geographical boundaries using the internet. However, the information transmitted can be intercepted by the middle of the road which is not desired, then the security of the data actually becomes a very important issue. The development of computer systems and networks and the interconnection through the Internet has increased, of course, require data security and reliable message in order to avoid the attack. To secure internet data or message network necessary cryptographic encryption methods, one method of data encryption that there is a method of data encryption standard (DES) and subsequently inserted into the Lakeside digital images (steganography) using the method of least significant bit (LSB).

Secured Data

Steganography and cryptographic methods are used together with wavelets to increase the security of the data while transmitting through networks. Another technology, the digital watermarking is the process of embedding information into a digital (image) signal. Before embedding the plain text into the image, the plain text is encrypted by using Data Encryption Standard (DES) algorithm. The encrypted text is embedded into the LL subband of the wavelet decomposed image using Least Significant Bit (LSB) method. Then the inverse wavelet transform is applied and the resultant image is transmitted to the receiver. The receiver will perform the same operations in reverse order.

This paper devotes itself to the study of secret message delivery using the cover image and introduces a novel steganography technique based on bat algorithm. To maintain the same quality even after extraction of the image at the receiving end of the system, we used a data encryption standard approach integrated with wavelet transform for preserving high security. Also to increase the embed capacity modified BAT technique is used that results in high PSNR and low MSE values. With the help of modifications to exploitation, swarm initialization and Torus gives rise to (M-BAT) for fast convergence rate. All the simulations are carried with Matlab 2017a and its evaluation parameters are related with other traditional techniques.
