“…The Blowfish algorithm is a suitable alternative to existing encryption schemes because it is an unpatented, freely available fast algorithm, that Bruce Schneier designed and published in 1993 [18]. Blowfish is fast as it runs on 32-bit microprocessors, small because it can run in less than 5KB of memory [15], and simple since it just employs elementary operations like addition, xanthine oxidoreductase (XOR), and table lookup [19]. It is a symmetric block cipher as it encrypts and decrypts data using the same encryption key.…”

“…Furthermore, they are merging the above-generated image with the red, green, and blue (RGB) components of a host image to improve privacy and security, resulting in a more secure image. In the manuscript of Swathi et al [15], The image and data have been encrypted using the LSB technique, and after the sender has encrypted the original image, the data-hider will choose and compress a sequence of bits from which some of the given room will be used to create the cipher text. Selected cipher bits will be encoded using the Blowfish algorithm.…”

Recently, there is increasing interest in data transfer between many different devices. Data must be encrypted before being sent so that the intended receiver can only read it to prevent unauthorized access and processing of a secret message. This paper suggests two levels of security to secure import messages that are sent via the internet. A secret text is encrypted by a Blowfish algorithm, then the secret text is hidden in an image by the least significant bit (LSB) technique. The LSB method of concealing important information was developed to conceal at least the first of at least two bits, depending on the cover data. The resolution of an image is raised in our work where the sender selects a stego image with a high peak signal to noise ratio (PSNR). The receiver knows all the necessary information for decoding by the first nine pixels. The PSNR is used for evaluating the resolution of the image to check robustness at sending. The number of PSNR illustrates in our proposal that the resolution of the image is near the original LSB technique, but the embedding is more randomly robust in steganography.
