Plivo is introducing PIN-based authentication to its robust Number Masking API. This feature is designed to expand the utility and coverage of our number masking capabilities, catering to a broader range of use cases, including scenarios where calls originate from numbers that are not part of the number-masking session.
What is PIN-based Number Masking?
PIN-based number masking builds on our existing number masking solution, which anonymizes the phone numbers of parties in a call by using an intermediate virtual number. The new feature introduces a PIN authentication layer, enabling seamless connection even when calls originate from numbers that are not part of the number-masking session. This is particularly useful for situations where users may have multiple phone numbers or when calls are made from a number not previously associated with the application.
For example, imagine a user who signed up on a ride-sharing app with their primary phone number (let's call it Number X). One day, they need to call their driver but find that their primary phone is out of battery. They decide to use a different phone (Number Y) and call from a number that is not part of the number-masking session. Thanks to PIN-based Number Masking, they can still make the call. In such scenarios Plivo will ask for a PIN, and once the caller enters it correctly, the call connects to the driver, all the while keeping both parties' actual numbers hidden.
Who Benefits from PIN-based Number Masking?
This solution is tailor-made for businesses that operate in dynamic environments where end users or service providers use multiple SIMs or phone numbers. Whether it's a delivery service connecting drivers and customers, or a healthcare provider ensuring patient confidentiality, PIN-based number masking ensures that every call is securely connected, regardless of the phone number used.
How Does It Work?
When a call is initiated from an unregistered number, the caller is prompted to enter a PIN. This PIN, either set by the user or automatically generated by Plivo, verifies the caller's identity and connects them to the intended party, all while maintaining the anonymity of both parties' phone numbers.
Getting Started with PIN-based Number Masking
The adoption of PIN-based Number Masking involves a straightforward process, ensuring businesses can easily integrate this feature into their existing systems. Here's how to get started:
- Account Setup: Ensure you have an active Plivo account. If not, sign up with your business email and acquire a voice-enabled Plivo phone number, essential for creating number masking sessions. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.
- Creating a PIN-Based Session: Use a simple cURL request to kickstart your number masking session with PIN authentication enabled. This request should include both parties' phone numbers, a flag to enable PIN authentication (is_pin_authentication_required), and the PINs for both parties. You can also specify audio prompts for PIN entry and incorrect PIN attempts.
Here’s a basic template:
Ensure that is_pin_authentication_required is set to true for sessions requiring PIN verification. This step is vital for authenticating calls from unknown numbers.
- Configuration and Customization: Tailor the session to your specific needs by configuring optional parameters. These include setting custom PIN prompts and actions for incorrect PIN entries, thus offering a personalized experience for your users. Further details about these attributes can be found in the session object description.
- Session and PIN Management: Upon session creation, both parties receive the same virtual number. The PIN generated by Plivo will be unique for each party. Customers also have the option to generate unique pins for the parties involved. Plivo's system seamlessly handles the authentication, connecting calls upon successful PIN verification.
- Monitoring and Feedback: Plivo's infrastructure provides callbacks for real-time updates on PIN authentication status and session interactions. This feature is invaluable for maintaining oversight and optimizing the call experience based on actual usage.
Why Choose PIN-Based Number Masking?
PIN-based number masking enhances security and flexibility, ensuring calls are authenticated even from unregistered numbers. This level of authentication is crucial for businesses that prioritize customer confidentiality and security, such as healthcare providers, ride-sharing services, and delivery platforms. By integrating this feature, businesses can reassure their users that their privacy is protected, and their interactions are secure, no matter which phone number they use.
