Data Protection Using Optical System and Steganography Tool
Anirban Patra, Samiran Roy, Arijit Saha, Sonali Sarkar · 2023
Researchers have been using steganography, or the art of hiding secret information, extensively for the past few decades. However, because commercial stenography tools are readily available, most individuals use them. With the majority of these instruments, secret information can be easily unlocked by following a different procedure. Therefore, employing this kind of steganography tool to securely transfer personal information is a challenging undertaking. In this correspondence, we put forth a brand-new encryption technique that inserts concealed data into the text and staga images of the optical system (grating). There are two steps to the overall encryption process. Using the commercially available steganographic program Steghide, the images, and messages are first concealed among other images before being modulated in the optical grating system. The random phase matrix further processes the final object in the second section. We experimented with various decryption programs and found it impossible to successfully decrypt the secret text and image. As a result, the steganographic technique can safely be used to protect information that is hidden.
