DIGITAL SIGNATURE-OVER-VOICE FOR CALLER ID VERIFICATION

摘要

In an approach to caller ID verification by digital signature, a computing device receives authenticating information associated with a caller. The computing device creates a call record based on the authenticating information. The computing device retrieves additional information associated with the caller. The computing device updates the call record based on the additional information. The computing device retrieves a digital signature associated with the caller. The computing device retrieves public key information associated with the caller. The computing device performs a digital signature assessment based on the public key information. The computing device updates the call record based on the digital signature assessment. The computing device adds timestamp information to the call record. The computing device receives a request from a call recipient device. The computing device communicates information based on the call record to the call recipient device. The computing device marks the call record as expired.

主权项

1. A computer-implemented method for verifying an identity of a caller, comprising:
receiving, by one or more computer processors, authenticating information associated with a caller, wherein the authenticating information comprises a password, caller ID information, a caller phone number, a recipient phone number, and a URL; creating, by one or more computer processors, a call record based on the authenticating information; retrieving, by one or more computer processors, additional information associated with the caller; updating, by one or more computer processors, the call record based on the additional information associated with the caller; retrieving, by one or more computer processors, based on interfacing with the URL, a digital signature associated with the caller; retrieving, by one or more computer processors, public key information associated with the caller; performing, by one or more computer processors, a digital signature assessment based on the public key information, wherein the digital signature assessment comprises a determination that the digital signature is valid, not valid, or unverifiable; updating, by one or more computer processors, the call record based on the digital signature assessment; adding, by one or more computer processors, timestamp information to the call record; receiving, by one or more computer processors, a request from a call recipient device; communicating, by one or more computer processors, information based on the call record to the call recipient device; and marking, by one or more computer processors, after a predefined length of time from the addition of the timestamp, the call record as expired.
