technologies has transformed the financial sector, introducing both opportunities and security challenges. Blockchain technology, while providing transparency and security, still faces vulnerabilities in certain areas, including transaction privacy and data integrity. Visual cryptography (VC) and steganography offer unique methods to further enhance security, especially in banking transactions. Visual cryptography uses multiple shares to encrypt images in a way that can only be decrypted visually, while steganography hides secret data within a cover medium, such as images or audio. This paper explores the integration of these techniques with blockchain technology to provide enhanced security for banking transaction recording. By combining these advanced cryptographic and encoding methods with blockchain’s decentralized, immutable nature, this approach promises a higher level of privacy and data protection for financial transactions. We present a theoretical model for integrating VC and steganography into blockchain, discuss its potential applications, and analyze the challenges and benefits of such a system.
This concern has led to the exploration of advanced cryptographic techniques such as Visual Cryptography and Steganography to complement blockchain’s security features. Visual Cryptography (VC) is a technique that encrypts data into visual images, dividing it into multiple shares, where the secret data is revealed only when the shares are combined. This offers a novel way of ensuring that sensitive information remains hidden from unauthorized access while still being accessible to the authorized parties. On the other hand, Steganography provides a mechanism for hiding information within seemingly innocuous data—such as an image or a file—making it imperceptible to an observer without the appropriate key or method to decode it. By integrating Visual Cryptography and Steganography with Blockchain, this paper explores a potential solution to the problem of secure banking transaction recording, combining the strengths of all three technologies to create a more secure, private, and tamper-proof system for financial transactions. This integration would allow for the concealment of sensitive transaction details in ways that are both visually secure and difficult to detect, ensuring that banking data remains private even on a public, decentralized blockchain ledger.

1. Introduction The advent of digital banking has revolutionized the financial industry, making transactions faster, more efficient, and more accessible. However, the rapid shift towards digital systems has also introduced a host of security challenges, particularly concerning the privacy and integrity of sensitive financial data. Blockchain technology has emerged as a robust solution for addressing some of these challenges. By providing a decentralized, immutable, and transparent ledger for recording transactions, blockchain ensures that once data is recorded, it cannot be altered or tampered with, which is a fundamental attribute for securing financial transactions. Yet, despite these advantages, blockchain’s transparency can sometimes pose a risk to the confidentiality of transaction data. In a financial
