Through the Telefónica Open Gateway initiative, we have turned our networks into developer-ready platforms to facilitate the creation of optimised digital services. Thus, through Telco APIs that are standardised under the framework of the CAMERA forum, we provide developers with advanced functionalities that, among other things, help protect customers from fraud.
“SIM swapping” is a scam that involves fraudulently duplicating the SIM card of a mobile phone. The cybercriminal impersonates the person to get a duplicate SIM card and, once he has access to the card, is able to receive the victim's text messages and calls, as well as access accounts and obtain personal information. To combat this problem, the SIM Swap API helps to create security measures that prevent this type of fraud, offering an additional layer of security.
A tour of the SIM Swap API
This API provides real-time information about the SIM card associated with a mobile phone number. It provides data on the date and time of the last SIM card change and thus confirms with the user if he/she has indeed made the change voluntarily. The API also checks whether a SIM card change has been made during a certain period of time. With this information, measures can be taken to protect customers and provide an additional layer of security in account creation processes, user authentication and improved user experience.
The SIM Swap API is particularly useful for companies that use SMS to send one-time codes (OTP) as a means of two-factor authentication. These companies are particularly vulnerable to SIM card swapping fraud, as fraudsters can gain control of a mobile phone number and receive the OTP codes sent by the company. By using the SIM Swap API, companies can verify whether the SIM card associated with a mobile phone number has been changed recently, which may indicate a possible attempt at identity theft and fraud.
Discover the use cases of he SIM Swap API
In sign-up or login situations, the API offers a second factor authentication (2FA) enforcement. If the user wants to create a new account on a social network or log into their bank account from their mobile phone, the API heightens the security of traditional 2FA based on recent SIM events. This allows for more robust user verification and, therefore, greater security in a possible banking transaction.
When performing relevant transactions from the mobile phone, such as a transfer, payment or order, it is important for the application provider to have the assurance that the customer’s identity has not been supplanted. As for the customer, it is essential for them to be protected against this type of criminal impersonation. The SIM Swap API is key to detecting this type of account takeover fraud, which allows others to do transactions in the name of the legitimate user.
As a user's confidential medical data requires special protection, the SIM Swap API can bolster security protocols in digital health services. With this solution, it is easier and more secure to protect electronic medical records, telemedicine sessions and remote monitoring systems, thus contributing to the evolving healthcare landscape.These are just some of the use cases for the SIM Swap API, thanks to its potential to protect the user.
