In today's digital age, the apps we use for social and business things are getting more advanced, so we need better ways to check if you are really you. Two-Factor Authentication (2FA) is crucial for making the usual way we confirm identities better, but it does have some challenges. Usual 2FA methods have vulnerabilities such as SIM swapping, denial of service (DoS), and man-in-the-middle (MITM)[1] attacks.These issues continue to exist even when services say they have strong encryption. The central system in 2FA is also problematic because if it's breached, an attacker could impersonate an authorized user or mess up the whole service.To tackle these issues, we are proposing decentralized 2FA methods. This means spreading out the authentication process and using public key encryption. In this system, the user's secret keys are encrypted with their wallet's public key, giving users control over their authentication.Users can generate distinct passwords even without their main device. Therefore, as digital security needs grow, the limitations of traditional 2FA are clear. The solution is to shift to decentralized methods, offering better security and more control for users over how they authenticate.

Securing digital data from unauthorized access throughout its entire lifecycle has been always a critical concern. A robust data security system should protect the information assets of any organization against cybercriminal activities. The Twofish algorithm is one of the well-known symmetric key block cipher cryptographic algorithms and has been known for its rapid convergence. But when it comes to security, it is not the preferred cryptographic algorithm to use compared to other algorithms that have shown better security. Many applications and social platforms have adopted other symmetric key block cipher cryptographic algorithms such as the Advanced Encryption Standard (AES) algorithm to construct their main security wall. In this paper, a new modification for the original Twofish algorithm is proposed to strengthen its security and to take advantage of its fast convergence. The new algorithm has been named Split-n-Swap (SnS). Performance analysis of the new modification algorithm has been performed using different measurement metrics. The experimental results show that the complexity of the SnS algorithm exceeds that of the original Twofish algorithm while maintaining reasonable values for encryption and decryption times as well as memory utilization. A detailed analysis is given with the strength and limitation aspects of the proposed algorithm.

“…Graphical password authentication was improved upon by Gulsezim et al [15] with the Twofish Encryption and Visual Cryptography (TEVC) algorithm's utilization. There is an unpredictable organization of this proposed TEVC since it is much tougher to predict the correct graphical password and sort its particles into the appropriate order compared to the standard alphanumeric password system.…”

In Visual Cryptography Schemes (VCSs), for message n transparencies are generated, such that the original message is visible if any k of them are stacked. VCS especially for large values of k and n, the pixel expansion’s reduction and enhancement of the recovered images’ display quality continue to be critical issues. In addition to this, it is challenging to develop a practical and systematic approach to threshold VCSs. An optimization-based pixel-expansion-free threshold VCSs approach has been proposed for binary secret images’ encryption. Along with contrast, blackness is also treated as a performance metric for assessing the recovered images’ display quality. An ideally secure technique for a secret image’s protection through its partition into shadow images (known as shadows) is the Visual Secret Sharing (VSS) scheme. Acquirement of a smaller shadow size or a higher contrast is the VSS schemes’ latest focus. The white pixels’ frequency has been utilized to demonstrate the recovered image’s contrast in this work. While the Probabilistic VSS (ProbVSS) scheme is non-expansible, it can also be readily deployed depending upon the traditional VSS scheme. Initially, this work has defined the problem as a mathematical optimization model such that, while contingent on blackness and density-balance constraints, there is the maximization of the recovered images’ contrast. Afterward, an algorithm dependent on the Tabu Search (TS) is devised in this work for this problem’s resolution. Multiple complicated combinatorial problems have been successfully resolved with the powerful TS algorithm. Moreover, this work has attempted to bolster the contrast through the density-balance constraint’s slight relaxation. Compared to the older techniques, the proposed optimization-based approach is superior regarding the recovered images’ display quality and the pixel expansion factor from the experimental outcomes.
