“…It is very important to understand the encryption algorithm structure before putting it in the use. Navita Agarwal et al have develope Efficient Pixelshuffling Based Approach to Simultaneously Perform Image Compression, Encryption and Steganography [1]. The authors have conducted a similar research, where they have applied compression, encryption and steganography on the digital image data.…”

“…[Coutesy: Wikipedia] After applying the compression on the hidden object image, the very next step is to hide it inside the decomposed cover object. [1,[5][6][7] The hidden object is hid inside the most similar decomposition matrix of cover object. The similarity between the decomposed matrices and hidden object will be found by using the color based image analysis.…”

“…The specific decomposition matrix undergoes the extraction process using the reverse matrix calculation to obtain the secret image hidden inside it. [1,[6][7] The fourth objective is yet partially achieved by implementing the code for compression and steganography in MATLAB using normal coding in Matlab and Image Processing Tool Box. The compression module is completed by using 2-D HAAR wavelet for decomposition of image matrix using Haar wavelet based low pass and high pass filter and results in Approximation Coefficient Matrix and Detailed Coefficient Matrix.…”

“…It includes a combination of steganography, cryptography and compression. [1] Steganography relies on hiding covert message in unsuspected multimedia data and is generally used in secret communication between acknowledged parties. [13] Steganography is a method of encryption that hides data among the bits of a cover file, such as a graphic or an audio file.…”

The image security on internet transfers is the concern of the hour as the breaching attacks into the image databases are rising every year. The hackers take advantage of the stolen personal and important images to fulfill their dangerous and unethical intentions. The image data theft can be used to defame a person on the internet by posting the illegal and unacceptable images of that person (internet user). Hence the images transfers have to be secure to ensure the privacy of the user's image data. In this research, a number of image security systems have been studied to evaluate the research gap. Majority of the existing image security systems are not up to date to protect against the latest breaching attacks. So, we have proposed an effective and robust image security framework particularly designed for the images. The proposed has been designed and implemented using MATLAB. In this research, a hybrid image security framework has been proposed to overcome the problem stated earlier, which will be implemented by combining various techniques together to achieve the image security goal. The techniques included in the combination would beimage compression, cryptography and steganography. DWT compression has been used, because it is a stronger compression algorithm. The steganographed image would be compressed to reduce its size. Blowfish encryption algorithm would be used for the encryption purposes. It offers maximum throughput (faster) and also energy efficient. Compressed image would be encrypted to enhance the image security. Real image will be hidden into another image. A cluster based steganographic technique will be used. Real image and face image would be analyzed, and the real image would be embedded in those areas of face image, where color schemes of the real image and face image would be most similar. Kmeans or Hierarchical clustering would be used as a clustering technique. An all new comparative analysis technique would be applied to make the comparison between real image and base image on the basis of color patterns.

Nowadays secure and safe transmission of data is a very important aspect for all internet users. In the data securing process the use of encryption algorithms almost make it very difficult for an eavesdropper to get access to any user's data. It helps to ensure the privacy of a company/user from others. Keeping in view the importance of steganography and cryptography for secure data transmission this work incorporates the use of multiple keys, LSB substitution method and bit plane technique for further security of image containing data. Simulation results show the feasibility of the proposed method. The data has been successfully embedded using triple security.

Cryptographic methods or techniques are mathematical operations used to encrypt plaintext into cipher text and vice versa. The improved security of the encrypted message; the algorithm can be improved based on its complexity and the secrecy of the key used to encrypt and decrypt the message. Cryptosystems are a combination of cryptographic based algorithms, keys, and protocols that work together to provide secure communication. The strength of the encrypted data relies by improving the security of the cryptographic algorithm and how the key is secured during transmission over a network. The cryptographic algorithm should be strong enough for preventing the unauthorized access by keeping the key as secret to ensure that only the authorized people are able to access the encrypted data. Encryption of the data is a crucial step in securing data. Implementing the Blowfish algorithm and comparing its performance with the DES algorithm can provide insights into the strengths and weaknesses of both algorithms. By giving the data and key as input to the encryption block, the Blowfish algorithm can encrypt the data to protect its confidentiality. The comparison with DCT can also highlight the trade-offs between performance, security, and implementation complexity. The research in this paper has focused on the enhancement of Blowfish algorithm for securing the content in plaintext and file message using encryption techniques. The performance for Blowfish algorithm can be intensified by minimizing the rounds in reference with increasing the block length of fixed length by using the transformation model.
