The Rise of Real-Time and the WebSocket Challenge

In today's fast-paced digital world, real-time applications are no longer a luxury but a necessity. From instant messaging to live financial trading and collaborative platforms, users expect immediate feedback and up-to-the-minute information. WebSockets have emerged as the standard for enabling these real-time capabilities, providing persistent, full-duplex communication channels between clients and servers.

However, with the power of real-time communication comes significant security responsibilities, especially when dealing with sensitive identity data. Imagine an identity verification process where a user's status (e.g., 'verified,' 'pending review,' 'declined') needs to be updated instantly across various client applications. Without proper security, these real-time updates could be intercepted, altered, or accessed by unauthorized parties, leading to severe privacy breaches, fraud, and compliance violations. This is where securing your WebSocket connections becomes critically important.

Developers must meticulously consider authentication, authorization, data encryption, and integrity checks when designing systems that push identity updates over WebSockets. A single vulnerability could compromise user trust and expose your organization to significant risks. Didit's platform is designed with these challenges in mind, offering a secure and efficient way to handle identity verification and updates, including features like ID Verification and AML Screening & Monitoring, which often necessitate real-time status communication.

Establishing Secure WebSocket Connections: Authentication and Authorization

The foundation of secure WebSocket communication for identity updates lies in robust authentication and authorization. Just as with traditional HTTP requests, you need to verify the identity of the connecting client and determine what actions they are permitted to perform.

Authentication

For WebSockets, traditional session cookies or token-based authentication (like JWTs) are common. When a client initiates a WebSocket handshake, the server should validate the provided authentication credentials. For instance, a user who has just completed a Didit ID Verification session might receive a JWT upon successful verification. This JWT can then be sent with the WebSocket connection request (e.g., in a query parameter or a custom header during the handshake). The server would then validate this JWT, ensuring it's signed correctly, not expired, and contains the expected claims (e.g., user ID, verification status).

Example of an authenticated WebSocket URL (for demonstration, not recommended for production):

const token = 'YOUR_JWT_TOKEN';
const ws = new WebSocket(`wss://your-app.com/ws/identity-updates?token=${token}`);

A more secure approach involves using a short-lived token obtained via a prior HTTP request, which is then used only for the WebSocket handshake. After the connection is established, the token can be invalidated, or the server can maintain session state.

Authorization

Once authenticated, the server must authorize the client to receive specific identity updates. Not all users should see all updates. For example, an administrator might receive updates on all pending verifications, while a regular user only receives updates pertinent to their own verification status. This requires a robust authorization layer on the server that checks the user's roles and permissions before pushing any data.

Didit's modular architecture allows you to define granular workflows. When a user completes a step like Passive & Active Liveness detection, the result can trigger an authorized real-time update to specific clients, ensuring data segregation and compliance.

Data Integrity and Encryption: TLS/SSL for WebSockets

Beyond authentication and authorization, the actual data transmitted over WebSockets must be protected. This is achieved through encryption, and for WebSockets, the industry standard is to use Transport Layer Security (TLS), which underpins the wss:// protocol prefix (secure WebSockets).

Using wss:// ensures that all data exchanged between the client and server is encrypted end-to-end. This prevents eavesdropping and man-in-the-middle attacks, where malicious actors could intercept or alter identity verification results or sensitive personal information. It's crucial to implement TLS/SSL certificates correctly and regularly update them.

Furthermore, consider the integrity of the data. While TLS provides some integrity checks, for highly sensitive identity updates, you might want to implement additional measures like digital signatures on the data payload itself, especially if the data passes through multiple intermediary services before reaching the client. Didit's structured identity data ensures that the information received is consistent and reliable, making it easier to maintain integrity throughout your application's data flow.

Integrating Real-Time Identity Updates with Didit

Didit is built for the agentic era and offers powerful tools for integrating real-time identity updates. While Didit handles the core identity verification processes, you can leverage its API and webhooks to push real-time status changes to your WebSocket clients.

Leveraging Didit Webhooks

Didit's webhook system is your primary mechanism for receiving real-time notifications about the completion or status change of an identity verification session. When a user completes their ID Verification or Proof of Address check, Didit sends a webhook notification to your configured endpoint. Your backend server, acting as the webhook receiver, can then process this notification and push the relevant status update to connected WebSocket clients.

Here's a simplified flow:

1. User initiates a verification session via your application, which uses Didit's SDKs.
2. Didit processes the verification (e.g., OCR, Liveness Detection, AML Screening).
3. Upon completion or status change, Didit sends a signed webhook payload to your backend.
4. Your backend verifies the webhook signature (using your DIDIT_WEBHOOK_SECRET).
5. Based on the webhook data (e.g., session_id, status, decision), your backend determines which WebSocket clients need to be notified.
6. Your backend pushes a real-time update over the secure WebSocket connection to the authorized client(s).

This approach decouples the verification process from your real-time communication layer, enhancing scalability and security. Didit's API also allows you to didit_get_session_decision to retrieve the full result, which can then be formatted and sent via WebSocket.
