Centralizing Your Digital Identity Verification With the Prove Link™ SDK

In today's digital landscape, robust identity verification is no longer optional - it's essential.  Whether you're onboarding new users, securing transactions, or meeting compliance requirements, verifying digital identities is crucial. However, managing multiple verification methods and integrations can quickly become a developer's nightmare.

‍

This is where Prove Link™ technology comes in. Our solution simplifies identity verification by providing a centralized SDK that streamlines the integration process. This article will guide you through leveraging the Prove Link SDK to enhance your identity verification strategy.

‍

Why Centralize Your Identity Verification?

Simplify Integration

Instead of juggling multiple APIs and documentation, a centralized SDK offers a single point of integration for various verification methods. This offers several benefits:
‍

• Faster Time-to-Market: Simplified integration means less time spent on complex coding and configuration. This allows you to launch your identity verification feature more quickly, getting your product or service to market faster and gaining a competitive edge.
• Reduced Development Costs: Streamlined integration often translates to less development effort, which can lead to cost savings. You can allocate resources to other critical areas of your project.
• Improved User Experience: A seamless integration process results in a smoother user experience. Users can complete the identity verification process quickly and easily, leading to higher satisfaction and conversion rates.
• Enhanced Security: Simplified integration often comes with robust security features built-in. This can help protect sensitive user data and ensure compliance with data privacy regulations.
• Scalability: A well-integrated identity verification solution can scale with your business needs. It can accommodate increasing user volumes and adapt to evolving regulatory requirements.
• Focus on Core Product: By simplifying the integration process, you can free up development time to focus on your core product or service. This allows you to innovate and improve your offering, rather than getting bogged down in the complexities of identity verification.
  ‍

Improve Developer Experience  

Streamlined integration means faster development cycles and reduced time to market for your applications. This is crucial for several reasons:
‍

• Faster Development and Deployment: Well-designed SDKs, clear documentation, and comprehensive APIs make it easier to integrate identity verification into your applications. This translates to less time spent on setup and configuration, allowing you to deliver features to your users faster.
• Reduced Errors and Frustration: Clear guidelines, robust error handling, and helpful debugging tools minimize the chances of making mistakes during implementation. This saves you time and effort, leading to a smoother development process.
• Increased Productivity: A streamlined developer experience lets you focus on the core functionality of your application instead of wrestling with complex identity verification integrations. This boosts your productivity and allows you to accomplish more in less time.
• Enhanced Security: A well-supported identity verification solution with clear security best practices and built-in protections helps you implement robust security measures more easily, reducing the risk of vulnerabilities and data breaches.
• Improved User Experience: A seamless and user-friendly identity verification process leads to higher user satisfaction and increased adoption rates. By focusing on developer experience, you indirectly improve the overall user experience of your application.
• Future-Proofing: A well-maintained and regularly updated identity verification solution with a strong developer community ensures that your integration remains compatible with new technologies and evolving security standards.

Scale Your Business for Growth

As your needs grow, a centralized solution can easily scale to accommodate new verification methods and higher volumes. The two pillars that support this are scalability and flexibility.
‍

Scalability:
‍

• User Growth: Your user base may grow rapidly, and your identity verification system needs to handle increased traffic and verification requests without performance degradation or downtime.
• Global Expansion: If you plan to expand your service to different regions or countries, your system should be able to accommodate various identity documents and verification methods used worldwide.
• Seasonal Fluctuations: Certain industries or services experience seasonal peaks in user activity. Your system should be able to scale up or down to meet these fluctuations efficiently.
  ‍

Flexibility:
‍

• Evolving Regulations: Identity verification regulations and requirements can change frequently. Your system should be adaptable to these changes without requiring major overhauls.
• New Technologies and Verification Methods: New technologies and verification methods emerge constantly. Your system should be flexible enough to integrate these innovations to enhance security and user experience.
• Diverse User Needs: Different users may have varying preferences or limitations regarding identity verification. Your system should offer flexibility to accommodate different verification options, such as document uploads, biometric checks, or knowledge-based authentication.
• Custom Workflows: Your business or service may have unique identity verification requirements. Your system should allow customization to fit your specific workflows and risk tolerance.

Introducing Prove Link™ Technology

Prove Link™ technology empowers you to seamlessly integrate Prove's identity verification solutions into your applications.  When you need to pre-fill forms with verified data using Prove Pre-Fill®, the Prove Link SDK simplifies the process.
‍

Getting Started with Prove Link SDK

Let's walk through the steps to integrate Prove Link into your application:

‍

1. Quick Demo with Prove Pre-Fill® Starter Kit

The Prove Pre-Fill® Starter Kit provides a pre-built demo to get you up and running quickly.
‍

• Download and Run: Download or clone the starter kit and run it locally using the provided instructions.
• Explore Demo Mode: Start with the demo mode to see the flow in action.
• Connect to Sandbox: Create a Portal account and use your Sandbox credentials along with Prove Pre-Fill® Test Users to interact with the Prove sandbox environment.

2. Understanding the Prove Link™ Technology Flow

Familiarize yourself with the Prove Link Technology Flow Diagram to understand the components involved in integrating Prove Pre-Fill®. This will give you a clear picture of the interactions between your application, the Prove Link SDK, and the Prove platform.

‍

Below is a diagram of the interactions between your web application server and client to complete a Prove flow:
‍

• The Start call generates the OAuth token, initiates the session, and indicates the channel.
• The Client Side SDK initiates the Prove possession check. Note that for Mobile Channels, it includes Mobile Auth℠ for real-time, MNO-coordinated verification with fallback to SMS OTP (One-Time Passcode) to verify a consumer. For Desktop Channels, it includes Instant Link℠ where users click a fortified link within an SMS message.
• The Validate call indicates where Prove can successfully authenticate the possession and reputation checks.
• The Challenge call indicates whether Prove can authenticate the consumers identity information with enough trust and assurance. If so, Challenge passes back the consumer's verified identity information.
• The Complete call validates indicates whether Prove can authenticate the ownership.

‍

3. Implementing Prove Link in Your Application
‍

• Install Client SDK: Begin by installing the Prove Client Web SDK in your frontend application.

• Choose Your Server SDK: Select the appropriate Prove Server SDK for your backend language (Java, TypeScript/JavaScript, Go) and install it. The Server SDK handles OAuth authentication, request/response validation, and error handling.

• Direct API Integration: If your backend language isn't supported by a dedicated SDK, you can directly interact with Prove's API References.
