Abstract - This design presents e-KYC Trust Block, a
One of the primary concerns in centralized e-KYC systems is the lack of trust and transparency. Sensitive identity data stored in centralized cloud servers is susceptible to unauthorized access, data breaches, and insider threats. Furthermore, ensuring user consent and controlling access to personal data becomes increasingly difficult in such frameworks. As a result, there is an urgent need for an e-KYC solution that is secure, transparent, privacypreserving, and aligned with regulatory requirements such as data protection laws (e.g., GDPR, PDPB).
blockchain- grounded electronic Know Your client(e-KYC) system that enhances trust, security, and sequestration in identity verification. Traditional e-KYC systems calculate on pall storehouse and conventional encryption, leading to crucial operation complications and security vulnerabilities. To address these challenges, e-KYC Trust Block integrates Ciphertext Policy Attribute Grounded Encryption(CP- ABE) for fine- granulated access control and Interplanetary train System(IPFS) for secure document storehouse. also, it employs smart contracts to apply customer concurrence and insure auditability. By combining symmetric and publiccrucial encryption, the system minimizes communication outflow while maintaining data confidentiality. Experimental results validate its effectiveness, scalability, and security, making it a robust result for sequestrationconserving e-KYC processes.
To address these challenges, this paper proposes e-KYC TrustBlock, a decentralized, blockchain-based framework designed to enhance the trust, privacy, and security of the e-KYC process. The system utilizes Blockchain to ensure immutability and transparency of transactions, Ciphertext-Policy Attribute-Based Encryption (CPABE) to provide fine-grained access control over encrypted data, and InterPlanetary File System (IPFS) for decentralized and tamper-proof storage of sensitive identity documents. Furthermore, smart contracts are employed to enforce digital consent, automate authorization policies, and ensure accountability in every data-sharing event.

The proposed system offers several advantages over existing e-KYC models. It reduces reliance on centralized storage, mitigates risks of unauthorized data access, and improves scalability through distributed technologies. By integrating both symmetric and asymmetric encryption techniques, the system achieves secure data handling with minimal communication overhead. The architecture is designed to support secure onboarding, consent-driven data sharing, audit trails, and regulatory compliance.
In the era of digital transformation, identity verification has become a critical requirement for financial institutions, telecom providers, and various government agencies. The process of Know Your Customer (KYC) ensures that organizations verify the identity of their clients to prevent fraud, money laundering, and other illicit activities. With the advent of digitization, the traditional paper-based KYC processes have evolved into electronic KYC (e-KYC) systems, aiming to streamline verification and improve customer onboarding. However, these conventional e-KYC systems predominantly rely on centralized architectures and standard encryption models, which present major limitations in terms of data privacy, single points of failure, and complex key management.
