Securing Pictorial Data Transfer Through a Novel Digital Image Encryption Method

This paper introduces a singular method named ‘QUAD-direction visual cryptography,’ a method without cryptographic algorithms, aimed toward securely encrypting photos for seamless transmission across various media. Unlike traditional methods, QUAD-route visible cryptography does not compromise picture fine, ensuring negligible facts loss. This approach makes use of MATLAB and a sequence of algorithms to convert an input image into encrypted opposite numbers. The system includes Zig-Zag traversal of the input matrix, producing a one-dimensional array which, while transformed back to a -dimensional matrix, paperwork the encrypted image. This matrix undergoes anti-clockwise rotation, and the complete procedure is reiterated four times, generating the final converted image. This study introduces a thorough framework for encryption and decryption, emphasizing its superiority over current methods. Visual representations highlight the effectiveness of QUAD-PATH visual cryptography, underscoring its potential for secure image transmission in the digital era. Through fundamental matrix operations, this technique achieves encryption in visual cryptography, rendering the encrypted image visually indecipherable. The paper underscores the critical significance of secure data transmission in today's world, addressing the paramount challenge of securing pictorial data by presenting a viable solution.
