Method and system for auditory recognition biometrics on a FOB

A method for registering and using proffered auditory scan sample data for facilitating a Radio Frequency (RF) transaction, comprising:

• detecting a proffered auditory scan sample at an auditory scan sensor to create the proffered auditory scan sample data;
• detecting whether the proffered auditory scan sample is a false auditory emissions scan based on auditory scan characteristics;
• associating the proffered auditory scan sample data with at least one of an RF device, a user identifier, or a transaction account;
• verifying the proffered auditory scan sample data to activate the RF device and to confirm the proffered auditory scan sample data to create registered auditory scan sample data;
• receiving a transaction request from the RF device, wherein the transaction request comprises transaction auditory scan sample data;
• authorizing the transaction request in response to the transaction auditory scan sample data matching the registered auditory scan sample data;
• and
• placing a first RF transponder and a second RF transponder in at least one of a selectivity mode or an inclusivity mode in the RF device,
• wherein the selectivity mode includes enabling purchase of an item using a selected account number and the inclusivity mode includes the first and second RF transponders in an operational mode permitting the first and second RF transponders to be responsive to interrogation.

An authorized sample receiver (ASR) comprising:

• a biometric sensor configured to receive a first proffered auditory scan sample to create first proffered auditory scan sample data, wherein the biometric sensor is configured to detect a false auditory emissions scan based on auditory scan characteristics;
• means for a biometric processor configured to create registered auditory scan sample data from the first proffered auditory scan sample data in response to second proffered auditory scan sample data associated with an RF device matching the first proffered auditory scan sample data;
• auditory scan sample data, an encrypted device account code, and a device identification code;
• an authentication circuit configured to decrypt the encrypted device account code using a unique RF device decryption key selected from a plurality of device-specific decryption keys,
• wherein the authentication circuit is further configured to authenticate the RF device in response to the transaction auditory scan sample data matching the registered auditory scan sample data;
• and
• wherein the biometric sensor comprises a switch configured to place a first transponder and a second RF transponder in at least one of a selectivity mode or an inclusivity mode in the RF device,
• wherein the selectivity mode includes enabling purchase of an item using a selected account number and the inclusivity mode includes the first and second RF transponders in an operational mode permitting the first and second RF transponders to be responsive to interrogation.
