Patent number: 11748463Abstract: Systems and methods for call detail record (CDR) analysis to determine a risk score for a call and identify fraudulent activity and for fraud detection in Interactive Voice Response (IVR) systems. An example method may store information extracted from received calls. Queries of the stored information may be performed to select data using keys, wherein each key relates to one of the received calls, and wherein the queries are parallelized. The selected data may be transformed into feature vectors, wherein each feature vector relates to one of the received calls and includes a velocity feature and at least one of a behavior feature or a reputation feature. A risk score for the call may be generated during the call based on the feature vectors.Type: GrantFiled: January 25, 2021Date of Patent: September 5, 2023Assignee: PINDROP SECURITY, INC.Inventors: Scott Strong, Kailash Patil, David Dewey, Raj Bandyopadhyay, Telvis Calhoun, Vijay Balasubramaniyan
