Security Framework

Multi-Layered Security Architecture

Asymmetric Cryptography

Your DID is secured by public-private key pairs, with private keys never leaving your device. All authentication and signatures use cryptographic proofs rather than shared secrets.

Zero-Knowledge Proofs

Verify claims without revealing underlying data. For example, prove you're over 21 without sharing your birthdate, or prove your income range without disclosing exact figures.

Blockchain Immutability

DID registrations and revocations are recorded on the blockchain, creating a tamper-proof record that prevents unauthorized modifications to identity status.

Encrypted Data Storage

Personal data is stored in encrypted form, accessible only with your private keys. Even if a device is compromised, your identity information remains protected.

Frequently Asked Questions

Get clear answers to the most common questions about PayGlobalCoin’s Decentralized Identity (DID) system.

What is a Decentralized Identity (DID)?

A Decentralized Identity (DID) is a new form of digital identity that gives individuals full ownership and control over their personal information. Unlike traditional identity systems — where data is stored in centralized databases managed by corporations or governments — DIDs are self-sovereign: you manage your identity credentials directly from your digital wallet. Your personal data remains encrypted and under your control at all times. Only cryptographic verification proofs (not your actual data) are stored on the blockchain.

How does PayGlobalCoin's DID system work?

PayGlobalCoin’s DID system combines blockchain technology with advanced cryptography to create a secure, self-sovereign identity model. When you generate a DID, a unique identifier is created and recorded on the blockchain alongside a public key. Your private key — which grants you exclusive control over your identity — remains securely stored in your wallet and never leaves your device. Trusted entities can issue verifiable credentials to your DID, such as KYC verification, certifications, or memberships. When you need to prove something about yourself, you can share only the required information using cryptographic proofs — without exposing your actual data.

What are the privacy benefits of using a DID?

DIDs provide significant privacy advantages over traditional identity systems:

  • Selective disclosure allows you to share only specific attributes, without revealing your full identity.
  • Zero-knowledge proofs enable you to prove facts about yourself without exposing underlying personal data.
  • Encrypted storage ensures your personal information stays under your control — not in vulnerable centralized databases.
  • Contextual identity separation: you can create different DIDs for different services to prevent correlation and tracking.
  • No unnecessary oversharing: verify what’s needed without exposing more than necessary.

How secure is the DID system?

PayGlobalCoin’s DID system is designed with security at its core. It uses advanced cryptography — the same technology behind blockchain security — to protect your identity. Private keys never leave your device, and all personal data remains encrypted and under your control. The blockchain ensures an immutable record of identity events, and the system is verified through third-party security audits.

What happens if I lose access to my DID wallet?

PayGlobalCoin's DID system includes robust recovery mechanisms to help you regain access if you lose your device or forget your credentials. These include:

  • Social recovery options that allow trusted contacts to help you restore access
  • Secure backup systems for your private keys and credentials
  • Multi-device synchronization to maintain access across different devices
  • Recovery phrases that you can store securely offline

We recommend setting up these recovery options immediately after creating your DID to ensure you never permanently lose access to your digital identity.

How does DID comply with regulations like GDPR?

PayGlobalCoin's DID system is designed with privacy-by-default principles that align with global data protection regulations like GDPR. The system supports key regulatory requirements in several ways:

  • Right to be forgotten: You can revoke credentials and remove your DID from the system
  • Data minimization: Only the minimum necessary information is shared in any transaction
  • User consent: You explicitly approve every instance of data sharing
  • Data portability: Your credentials can be used across different services and platforms
  • Purpose limitation: Credentials can be restricted to specific uses and timeframes

This approach ensures compliance while enhancing privacy protection beyond what traditional systems offer.

Can businesses and organizations use the DID system?

Yes, businesses and organizations can participate in the DID ecosystem in several ways:

  • As credential issuers, providing verified credentials to users (e.g., banks issuing financial credentials)
  • As verifiers, accepting and validating credentials from users without storing personal data
  • By creating their own organizational DIDs to establish verifiable digital identities
  • By integrating DID authentication into their services to eliminate password vulnerabilities

Organizations benefit from reduced KYC costs, enhanced security, streamlined user experiences, and simplified compliance with data protection regulations.
