📋 Chapter 7: eKYC & Regulatory Compliance

7.1 What is eKYC?

Know Your Customer (KYC) is the process of verifying the identity of clients, required by law in financial services to prevent fraud, money laundering, terrorist financing, and other crimes. Electronic KYC (eKYC) digitizes this process, making it faster, cheaper, and more accurate.

7.1.1 Traditional KYC Problems

• Time-consuming: Days or weeks to verify identity
• Expensive: Manual review costs $15-$75 per customer
• Poor UX: In-person visits, document submission, long waits
• Redundant: Repeat process for each financial institution
• Error-prone: Manual data entry introduces mistakes

7.1.2 eKYC Benefits

• Fast: Minutes instead of days
• Cost-effective: Automated checks reduce costs by 80%+
• Better UX: Remote, mobile-friendly verification
• Reusable: Verify once, use credentials everywhere
• Accurate: Automated validation reduces errors

7.2 eKYC Process with Digital Identity

7.2.1 Identity Verification Steps

1. Document Verification: User uploads ID (passport, driver's license, national ID)
2. OCR & Validation: Extract data, check security features, validate with issuing authority
3. Biometric Matching: Selfie compared to document photo
4. Liveness Detection: Ensure real person, not photo/video
5. Database Checks: Verify against government databases, watchlists
6. Credential Issuance: Issue Verifiable Credential with KYC status

7.2.2 KYC Levels

7.3 Anti-Money Laundering (AML) Compliance

Financial institutions must implement AML programs to detect and prevent money laundering. Digital identity plays a crucial role:

7.3.1 Customer Due Diligence (CDD)

• Verify identity of customers
• Understand nature of customer relationship
• Assess risk of money laundering
• Ongoing monitoring of transactions

7.3.2 Enhanced Due Diligence (EDD)

For high-risk customers:

• Source of wealth verification
• Source of funds for specific transactions
• Purpose of account
• Expected transaction patterns

7.3.3 Beneficial Ownership

Identify real individuals who own/control legal entities:

• Ownership threshold: typically 25%+
• Control: voting rights, management
• Ultimate Beneficial Owner (UBO) identification

7.4 Privacy Regulations

7.4.1 GDPR (General Data Protection Regulation)
