Description

[0001] The present invention relates to the field of secure authentication systems, particularly in the area of ​​distributed ledger technologies. It specifically addresses cross-platform identity verification and access control mechanisms. The invention enables forgery-proof, decentralized, and interoperable authentication across different software environments.

[0002] In today's interconnected digital landscape, software systems operate across a variety of platforms, devices, and networks, often managed by different entities. Traditional authentication methods, such as centralized identity providers and platform-specific tokens, pose significant challenges in ensuring consistent and secure access. These methods are vulnerable to single points of failure, data breaches, and impersonation, which undermine user trust and system integrity.

[0003] Furthermore, interoperability between different authentication systems remains a major hurdle. Existing systems typically rely on proprietary protocols or are non-standardized, making it difficult to securely exchange identity credentials across different platforms. This fragmentation leads to increased complexity for developers and administrators, redundant user management processes, and reduced efficiency in collaborative environments.

[0004] To solve these problems, there is a growing need for a decentralized, tamper-proof, and scalable authentication framework. Distributed ledger technology (DLT) offers a promising foundation, enabling secure, transparent, and verifiable transactions without reliance on centralized authorities. Leveraging DLT for cross-platform authentication can solve the issues of trust, interoperability, and scalability, paving the way for a unified identity management system that is secure by design.

[0005] One goal of the present disclosure is to enable secure, decentralized user authentication without relying on central authorities.

[0006] Another objective of this disclosure is to facilitate seamless, cross-platform access using a single digital identity.

[0007] Another goal of this disclosure is to eliminate password-based vulnerabilities through cryptographic challenge-response mechanisms.

[0008] Another goal of this disclosure is to increase trust with immutable identity and access records on the distributed ledger.

[0009] Another objective of this disclosure is to support dynamic, automated access control using smart contract-based policies.

[0010] Another goal of this disclosure is easy integration into existing systems via standardized APIs and interoperability modules.

[0011] Another objective of this disclosure is to provide real-time audit trails and compliance support for regulatory requirements.

[0012] Another objective of this disclosure is to increase resilience against identity theft, manipulation and unauthorized access.

[0013] Further objects and advantages of the present disclosure will become apparent from the following description, which is not intended to limit the scope of the present disclosure.

[0014] The present invention relates to a decentralized authentication system that utilizes distributed ledger technology to enable secure and tamper-proof identity verification across multiple software platforms. It eliminates dependence on central authorities and increases trust and system resilience.

[0015] Another embodiment of the present invention is the user identity registration module, which ensures that each person is uniquely registered through a cryptographic key pair and minimal, hashed identity data that is immutably stored on the blockchain. This creates a secure and permanent digital identity foundation.

[0016] Another embodiment of the present invention is an authentication challenge processing module that facilitates cross-platform login attempts by generating and validating user-signed challenges.

[0017] Another embodiment of the present invention is the distributed ledger validation module, which ensures authenticity by verifying digital signatures using consensus mechanisms.

[0018] Another embodiment of the present invention is the cross-platform access control module that grants or denies access based on identity verification results and smart contract-driven access policies.

[0019] In another embodiment of the present invention, the smart contract policy engine dynamically manages and enforces access policies based on user roles, behaviors, or predefined rules.

[0020] Another embodiment of the present invention is an interoperability and API gateway module that enables seamless integration with various third-party platforms and legacy systems.

[0021] Another embodiment of the present invention is the audit and compliance monitoring module, which enables immutable tracking of all authentication and access events

[0022] The present invention relates to a secure distributed ledger authentication system (100) designed for cross-platform software environments. It uses blockchain technology to create decentralized, tamper-proof digital identities and replaces traditional password-based logins with cryptographic authentication. Through modular components such as smart contract-based access control and interoperable APIs, the system ensures seamless and secure access across different platforms. All authentication events are immutably logged, enabling transparency, audits, and regulatory compliance. This innovation addresses critical challenges in identity management, trust, and interoperability across distributed software systems. User identity registration module:

[0023] This module enables users to securely register their digital identities on a distributed ledger. Upon registration, a unique public-private key pair is generated, and the public key is immutably stored on the ledger along with minimal verifiable identity information (such as hashed biometric data or documents). The private key remains with the user and is securely stored in a local or hardware-based digital wallet. This decentralized identity creation ensures that user data cannot be falsified or altered by third parties. Module for processing authentication requests:

[0024] When a user attempts to access a cross-platform software service, this module initiates the authentication request. The user signs a request with their private key, and the signed message is submitted to the platform. The platform forwards this authentication data to the distributed ledger for identity verification. This approach eliminates the need for platform-specific credentials and enables seamless identity verification across different systems. Distributed Ledger Validation Module:

[0025] This module acts as the trusted backbone of the system. It validates authentication requests by comparing the digital signature with the registered identity's public key and metadata stored in the ledger. It uses consensus algorithms to verify transactions to ensure integrity and trustworthiness. Any attempt at tampering is immediately rejected, and all authentication events are timestamped and immutably recorded for audit purposes. Cross-platform access control module:

[0026] Once authentication is verified, this module manages authorization by matching the user's identity with a smart contract-based access policy. These policies determine the level of access granted to each identity on different platforms. The system ensures that a single identity token can be securely reused across multiple systems without requiring reauthentication or registration in each individual system. Smart Contract Policy Engine module:

[0027] This module governs dynamic access rules and authentication conditions using blockchain-based smart contracts. It enables administrators to create, update, and enforce access policies that automatically grant or revoke permissions based on user roles, behaviors, or predefined criteria. These smart contracts ensure that access control decisions are transparent, consistent, and free from manual errors or tampering. Interoperability and API Gateway Module:

[0028] To enable cross-platform functionality, this module provides standardized APIs and SDKs that enable integration with various software systems, platforms, and identity providers. It translates authentication and identity verification protocols into interoperable formats, ensuring that both legacy and modern systems can participate in the secure ledger-based ecosystem without having to redesign their authentication logic. Audit and compliance monitoring module:

[0029] This final module tracks and logs all authentication transactions, access attempts, and policy changes in real time. It provides dashboards and reporting tools for administrators to monitor suspicious activity, detect anomalies, and ensure compliance with regulatory standards such as GDPR, HIPAA, or ISO 27001. The immutable nature of the distributed ledger ensures that the audit trail is trustworthy and resistant to tampering.

[0030] The invention is explained again below with reference to the figure. It shows: Fig. : a secure distributed ledger authentication system (100) for cross-platform software systems.

[0031] Fig.illustrates a secure distributed ledger authentication system (100) for cross-platform software systems. The operation of the secure distributed ledger authentication system begins with the registration of a user's identity by the user identity registration module, which generates a cryptographic key pair and records the public key along with hashed identity metadata on the distributed ledger. When the user attempts to access a cross-platform software service, the authentication request handling module generates a cryptographic challenge, which the user signs with their private key. This signed challenge is then verified by the distributed ledger validation module, which compares the signature to the stored public key and uses consensus mechanisms to ensure the authenticity and integrity of the transaction.After successful validation, the cross-platform access control module consults the smart contract policy engine to determine user access rights based on predefined access rules and user roles encoded in smart contracts. The interoperability and API gateway module facilitates seamless communication between different platforms by translating authentication requests and responses into standardized formats, allowing systems to accept verified identities regardless of their native architecture. Throughout the process, the Audit & Compliance Monitoring Module logs all interactions and authentication events in the immutable ledger, providing administrators with real-time visibility and a tamper-proof audit trail for regulatory compliance and security monitoring.This end-to-end operation ensures secure, decentralized, and interoperable user authentication across different software ecosystems.
