What is FACEKI Biometric Authentication?

FACEKI Biometric Authentication is a facial recognition technology that provides secure log-in, enhances customer experience, and authenticates users. It can be fully integrated into your applications, websites, and access points using an API. With FACEKI, your customers can easily validate their identity and log in securely from anywhere, at any time, and on any device using a simple selfie.

Using advanced facial recognition technology, including 3D Passive Liveness and multi-factor authentication options, FACEKI ensures high accuracy and robust security to prevent spoofing attempts. The API is easy to use, allowing you to seamlessly integrate it into your existing systems.

How does it work?

Step 1: User Registration

When a user wants to authenticate their identity, they will need to register their information with your application, using your application's registration process. This can be a custom page in your application that collects information such as the user's first name, last name, mobile number, and email. Once the user completes this registration process, they will be directed to the authentication page.

Step 2: Authentication Request

On the authentication page, the user will be prompted to take a live selfie using their device's camera. This selfie will be submitted to the FACEKI API using the appropriate API endpoint. The FACEKI SDK will process the selfie and compare it to the stored biometric data in your application's database, if applicable, or perform a liveliness check if the user is not registered. Importantly, FACEKI only processes the data submitted and does not store the data in any way. If the authentication is successful, the FACEKI API will return a JSON response that includes information about the user's identity, which can be stored in your application's database. If the authentication fails, your application can prompt the user to try again or take other actions, such as requiring additional authentication methods.

Step 3: Integration

To integrate FACEKI Biometric Authentication into your application, you will need to use the FACEKI API, which provides RESTful endpoints for registering users, authenticating identities, and managing user data. The API documentation provides detailed information about the endpoints, their parameters, and their responses. You can use this documentation to build the necessary API requests in your application.

Step 4: Security

When integrating FACEKI Biometric Authentication into your application, it is important to follow best practices for security. This includes using HTTPS for all API requests, storing user data securely, and using appropriate encryption methods. Additionally, you should inform users about the biometric data that will be collected and how it will be used, and provide them with the option to opt out of biometric authentication if they prefer.
