Title: Innovations by Walter N. Scaife
Introduction
Walter N. Scaife is a notable inventor based in Gainesville, FL (US). He has made significant contributions to the field of technology, particularly in the areas of security and detection systems. With a total of five patents to his name, Scaife's work addresses critical issues in telecommunications and payment security.
Latest Patents
One of his latest patents is focused on detecting SS7 redirection attacks with audio-based distance bounding. This invention provides various embodiments for identifying these attacks by measuring call audio round trip times between phones. Such redirection attacks can force calls to travel longer physical distances than usual, resulting in longer end-to-end delays. The protocol implemented allows for securely characterizing the round trip time between two call endpoints, enabling telephone users to reliably detect SS7 redirection attacks and protect the information contained in their calls.
Another significant patent by Scaife is related to payment card overlay skimmer detection. This invention includes devices and methods for detecting credit card skimmers. The device comprises a printed circuit board with a pattern of electrical traces on its surface. It also includes a computer-readable medium with instructions that direct an electrical voltage to a trace and detect an electrical current between two points of the trace. A gap is disposed between the two points across which a voltage is applied to detect a magnetic reader. The count of detected magnetic readers within a credit card reading device may indicate the presence of a credit card skimmer.
