Abstract:

A processor receives global positioning system data from a mobile device of a user of an account. The processor further receives information from a vendor, indicating that a transaction using the account was attempted. The processor determines, based on historical transaction and location information, and current transaction information, a probability that the transaction is fraudulent. In response, the processor rejects the transaction, and deactivates a card and mobile wallet of the user. The processor also sends a notification to the mobile device requesting a voice confirmation. The processor receives the voice confirmation, splits it into a set of voice characteristic data and determines, based on voice characteristic data stored in memory, that the voice confirmation was generated by the user. In response, the processor reactivates the card and the mobile wallet and stores a set of information describing the transaction in memory.
