Automated verification of a telephone number

摘要

A system and method for automatically verifying a telephone number proffered by a user of an application. During registration or installation of the application, client software is installed on the user's mobile device (e.g., a smart phone, a tablet computer). One of a pool of telephone numbers for outgoing calls is selected, and a call is initiated to the proffered number by the system. The software executing on the user's device detects the incoming call, extracts caller identification data (i.e., the originating telephone number), formats a data communication (e.g., an http request) to include the data, and sends it to the system. The system receives the data communication and compares the data with the originating number. If they match, the user's telephone number is verified. The outgoing call from the system may be canceled before it rings at the device if the data communication is received in time.

主权项

1. A processor-implemented method of automated verification of a telephone number, the method comprising:
identifying a destination telephone number; selecting one of multiple origination telephone numbers; initiating a call to the destination telephone number assigned to a device from the selected origination telephone number, the called device configured to listen for incoming calls and receive signaling data before an incoming call rings at the called device; receiving, from the called device, a data communication comprising a telephone number extracted from the signaling data of the call before the call rings at the called device; comparing the telephone number of the data communication to the selected origination telephone number before the call rings at the called device; allowing access by a client software application on the called device to a service, when the telephone number of the data communication matches the selected origination telephone number; and canceling the call before the call rings at the called device when the telephone number of the data communication matches the selected origination telephone number.
