Abstract:
In this paper we represent the web-based authentication security system which uses Image
Steganography and SHA3-512 hashing function. Our developed web authentication system
encrypts user’s password with SHA3-512 hashing function which hides into a cover image
is called image steganography. Pixel selection for data hiding becomes crucial for the
solutions in spatial domain of image steganography to ensure imperceptibility. This paper
also presents an efficient approach of pixel selection technique for hiding secret data in
cover object of image steganography. After reviewing recent literature, it has been observed
that most of the works on pixel selection uses zig-zag technique for their solution. However,
it becomes very prone to steganalysis based attacks by the intruders. In this study, 8-
directions pixel selection technique is proposed to embed data in the cover image where
Least Significant Bit (LSB) method has been used on Red, Green and Blue (RGB) color
image especially focused on JPG, JPEG, and PNG. Since this projected procedure avoids
the known steganalysis techniques, it will be challenging for the attacker to recognize the
presence of secret information from the stego image. To measure the quality, statistical
analysis has been performed where the value of the quality measurement matrices has
provided better results. We endorse this security for forthcoming web applications of the
future that will be handling subtle user information.
