Shalini.S, II MCA, Sri Muthukumaran Institution Of Technology, Mangadu, Chennai DR. Pandian.E Assistant Professor, Sri Muthukumaran Institution Of Technology, Mangadu, Chennai ABSTRACT Digital identity is akin to a digital version of a physical ID, such as a passport or driver’s license, containing various attributes that represent a user online. Currently, centralized and federated identity management systems, such as those enabling logins via Google or Facebook, dominate the digital landscape. While these systems simplify access, they pose significant risks. Centralized systems are vulnerable to large-scale data breaches, and federated models often allow companies to track user data without consent. Existing identity management approaches either rely on centralized servers or entrust identity providers with user authentication, often compromising data privacy and hindering the portability of identity information. To address these challenges, a more secure and reliable system is necessary—one that empowers users to manage their digital identities independently and securely. This need has driven the development of the Sign Up Wallet, a Self-Sovereign Identity (SSI) model utilizing blockchain and machine learning to safeguard digital identities. Blockchain technology supports decentralized identity management, removing the need for third-party identity providers, while machine learning identifies trusted service providers. Users store their digital identity within the Sign Up Wallet using cryptographic keys. When interacting with a service provider, they submit a Unique Personal Identifier (UPI) for direct credential verification. To assess the trustworthiness of websites, Logistic Regression is employed. If a service provider is deemed untrustworthy, a masked credential is generated using a Lookup Substitution Algorithm, ensuring privacy during the verification process. This approach allows for secure verification without exposing sensitive data, granting individuals greater control over their digital identities and reducing reliance on centralized authorities, thus minimizing the risks of data breaches and privacy infringements. Keywords: Digital identity, Centralized identity management, Federated identity management, Data privacy, Block chain, Machine learning, Sign Up Wallet. (1) INTRODUCTION "Sign up" refers to the process of creating an online account by providing an email address, username, and password, typically to access a website or web-based service. After signing up, users can log in to access their account. A signup form is the interface where users enter the necessary information to gain access to a website's services. The specific details requested in a signup form vary depending on the nature of the website and its offerings, but most commonly include a name, email address, username, and password.

By leveraging the secure Wallet Chain, blockchain technology, and machine learning, the system overcomes the limitations of traditional identity management models. Each user is assigned a Unique Personal Identifier (UPI) Code, which serves as a secure anchor within the Wallet Chain network. Multi-step verification methods, including email and mobile confirmation, ensure the authenticity of user identities. Trusted service providers can easily verify user credentials using the UPI Code, simplifying the registration process. For interactions with untrusted service providers, the system employs a privacy-preserving mechanism that generates masked credentials through a Lookup Substitution Algorithm, safeguarding user data while still allowing secure verification. Machine learning, specifically Logistic Regression, is utilized to predict the trustworthiness of websites, adding another layer of security by identifying reliable sites. Ultimately, the Sign Up Wallet System gives users enhanced control over their digital identities, offering a secure, decentralized, and user-focused solution that addresses existing challenges and sets a new benchmark for the future of digital identity management. (9) FUTURE ENHANCEMENT Future enhancements for the Sign Up Wallet System are strategically focused on strengthening security, broadening its applications, and providing users with even greater control over their digital identities. Planned upgrades include the integration of advanced biometric authentication to further enhance security, an expanded array of use cases beyond website trust prediction, and user-directed data sharing features. Additionally, the introduction of a dedicated mobile wallet app is set to offer users seamless and secure management of their digital identities while on the move. These enhancements will collectively enhance the system's versatility, security, and user-centric design, ensuring it remains in step with evolving technological advancements and user expectations in the digital identity management space.
