摘要

The safeguarding of information that is both public and private or data being transferred has grown into a difficult undertaking as the amount of information transmitted through the Internet and the World Wide Web increases. In order to prevent unwanted access to data sent over Internet communications, encryption techniques have evolved over time to encompass a variety of processes and computations. Either the encryption and decryption processes need the completion of unique algorithms because they are the opposite processes of encryption, allowing the original secret information to be recovered through decryption. This demonstrates that the encryption and decryption processes need a significant amount of time and resources. However, visual cryptography (VC), which involves fewer steps and less complexity, offers an efficient method for solving this issue. Since decryption may be accomplished easily, the encryption is the primary focus in VC. Since a specific algorithm is going to be required for picture or information encryption, human vision systems may be able to decrypt data. The suggested method’s security algorithm employs a 16-standard color code format, which aids in creating shares from the original image and half-tones it employing an XOR operation. Decryption can be done simply by arranging the shares and employing human vision, requiring no additional effort.
