Abstract

A method for conducting a transaction over an electronic network may comprise receiving transaction data, receiving biometric data including a relational check code representative of the biometric data, a date time stamp, an identifier of the hardware that recorded the biometric data, or a combination thereof, comparing the biometric data with biometric data previously stored, or with a predetermined threshold value, or with a combination thereof, for authenticating the biometric data for approving or disapproving the transaction. If approved, the transaction data is processed for conducting the transaction. Biometric data may include a locus-based digitized signature, a biometric digital signature, a fingerprint, a palm print, hand geometry, facial geometry, an iris scan, an iris print, a retinal scan, a retinal print, an eye scan, an eye print, or any combination thereof.

Claims

1. A method for conducting a transaction over an electronic network comprising:

receiving at a transaction server transaction data that is relevant to the transaction, wherein the transaction server is accessible via the electronic network for processing a transaction;

receiving at the transaction server biometric data for authorizing the transaction, wherein the biometric data includes a locus-based digitized signature, a biometric digital signature, a fingerprint, a palm print, hand geometry, facial geometry, an iris scan, an iris print, a retinal scan, a retinal print, an eye scan, an eye print, or any combination of the foregoing,

wherein the biometric data is included in a biometric data file that includes a date time stamp or an identifier of the hardware that recorded the biometric data, or both, and wherein the date time stamp is obtained from the transaction server, or from a server of the electronic network, or from both; and

wherein the biometric data file also includes a relational check code representative of the biometric data, of the biometric data and the date time stamp, of the biometric data and the identifier of the hardware that recorded the biometric data, or of the biometric data and the date time stamp and the identifier of the hardware that recorded the biometric data;

comparing the biometric data from the biometric data file with biometric data previously stored in a database, or with a predetermined threshold value, or with biometric data previously stored in a database and a predetermined threshold value, for authenticating the biometric data for approving or disapproving the transaction; and

if the transaction is approved, then processing the transaction data for conducting the transaction.

2. The method for conducting a transaction of claim 1 wherein authenticating the biometric data comprises:

generating a relational check code from at least the biometric data from the received biometric data file, and comparing the generated relational check code with the relational check code of the received biometric data file;

or

comparing the time stamp of the received biometric data file with the time stamp of the biometric data previously stored in a database;

or

comparing the biometric data from the received biometric data file with a predetermined threshold value;

or any combination of the foregoing.

3. The method for conducting a transaction of claim 1 wherein the biometric data file is further associated with the transaction data in a transaction data file including a further relational check code representative thereof.

4. The method for conducting a transaction of claim 3 wherein the biometric data file, the transaction data file, or both, are encrypted for transmission to the server.

5. The method for conducting a transaction of claim 1 further comprising providing a digitized biometric data capturing software application downloadable from the server.

6. The method for conducting a transaction of claim 1 further comprising providing voice assistance, voice instruction, audible instructions, voice feedback of data entered, audible confirmation, providing a signature capturing device usable by a visually impaired person, an enlarged display, Braille readout, Braille input, or any combination of the foregoing.

7. The method for conducting a transaction of claim 1 further comprising limiting a user from attempting to conduct the transaction after a predetermined number of attempts wherein a matching of digitized biometric data is not successful, wherein the limitation may be for a predetermined period of time or may be permanent.

8. The method for conducting a transaction of claim 1 further comprising generating an audit trail for each transaction, for failed attempts to conduct a transaction, or for both.

9. The method for conducting a transaction of claim 1 further comprising providing a threshold for approving the transaction, wherein the threshold has a value that is optionally related to the circumstance of the transaction.

10. The method for conducting a transaction of claim 9 wherein the circumstance of the transaction includes:

the value of the transaction, the transaction is a credit card transaction, the transaction is a credit card transaction having a value less than $25, the transaction is a credit card transaction having a value over $500, the transaction is voter registration, the transaction is voting, the transaction is signature authentication, the transaction is alias signature authentication, the transaction is comparing with one or more reference signatures, or the transaction is for classified access.

11. The method for conducting a transaction of claim 1 wherein the electronic network includes a wire, a cable, a telephone system, an optical fiber, an optical transmission, a radio or other RF transmission, a network, a computer network, a LAN, a WAN, an Intranet, the Internet, another communication link, or any combination of the foregoing.
