Multiple-Point Cognitive Identity Challenge System Using Voice Analysis

摘要

A mechanism is provided for verifying an identity of a user using dynamically generated questions based on transactions conducted by the user. One or more transaction based sources associated with the user are scanned for a set of transactions conducted by the user. A subset of transactions from the set of transactions are randomly selected as the basis for forming a set of questions to be used to verify the identity of the user. The set of questions are generated such that the user is required to identify one or more details about the subset of transactions in order to verify the user's identity. Responsive to the user correctly answering the one or more details about each of the subset of transactions vocally and voice analysis of the answers to the set of questions failing to indicate any discrepancy, the user is authenticated.
