## CPC

- G06Q 20/40145: {Biometric identity checks}
- G06Q: INFORMATION AND COMMUNICATION TECHNOLOGY [ICT] SPECIALLY ADAPTED FOR ADMINISTRATIVE, COMMERCIAL, FINANCIAL, MANAGERIAL OR SUPERVISORY PURPOSES; SYSTEMS OR METHODS SPECIALLY ADAPTED FOR ADMINISTRATIVE, COMMERCIAL, FINANCIAL, MANAGERIAL OR SUPERVISORY PURPOSES, NOT OTHERWISE PROVIDED FOR

## Abstract

An apparatus adapted to authorise a transaction having a requested payment amount comprises receiving circuitry to receive a request to authorise the transaction, the request indicating the requested payment amount of the transaction, input circuitry to receive one or more user inputs required from the user to authorise the transaction and authorising circuitry to authorise the transaction when the one or more user inputs correspond to a user input payment amount that is the same as the requested payment amount of the transaction.

## Claims

### Claim 1

An apparatus configured to authorise a specific transaction having a requested payment amount, comprising:
receiving circuitry configured to receive a request to authorise the specific transaction, the request indicating the requested payment amount of the specific transaction;
input circuitry configured to receive one or more user inputs from a plurality of biometric sources of the user; and
authorising circuitry configured to:
associate each respective biometric source with a respective numeral according to a predetermined mapping of the biometric sources to one or more numerals,
determine a set of provided numerals based on the biometric sources used for the one or more user inputs,
compare the provided numerals to the requested payment amount, to determine whether there is a match, and in response to the match to assert that the specific transaction has been securely authorised by the user, wherein:
in response to the provided numerals instead matching a different requested payment amount from a different transaction, the authorizing circuitry is configured to not assert that the specific transaction was securely authorised by the user, and
the input circuitry comprises one or more of the following:
one or more sensors to detect a fingerprint of a user;
one or more image sensors to detect at least one of a retina and an iris of a user; and
one or more audio sensors configured to detect a voiceprint of a user.

### Claim 2 (depends on 1)

An apparatus according to claim 1, wherein the authorising circuitry is configured to biometrically authenticate each of the one or more user inputs.

### Claim 3 (depends on 1)

An apparatus according to claim 1, comprising:
processing circuitry configured to generate an image to display an indicated payment amount of the specific transaction.

### Claim 4 (depends on 3)

An apparatus according to claim 3, wherein the processing circuitry is configured to determine one or more user inputs that correspond to a user input payment amount that is the same as the indicated payment amount and to generate the image to display one or more indicators indicating the one or more user inputs that correspond to the indicated payment amount.

### Claim 5 (depends on 3)

An apparatus according to claim 3, wherein the processing circuitry is configured to determine one or more user inputs that correspond to a user input payment amount that is the same as the requested payment amount and to generate the image to display one or more indicators indicating the one or more user inputs that correspond to the requested payment amount.

### Claim 6 (depends on 5)

An apparatus according to claim 5, wherein the one or more indicators indicating the one or more user inputs that correspond to the requested payment amount inform the user of the value of the requested payment amount.

### Claim 7 (depends on 4)

An apparatus according to claim 4, wherein the processing circuitry is configured to determine a number of respective user inputs and an order of the respective user inputs in dependence upon the value of either the indicated payment amount or the requested payment amount according to a predetermined mapping of one or more user inputs to one or more numerals.

### Claim 8 (depends on 1)

An apparatus according to claim 1, wherein the mapping is determined by a user defined mapping table.

### Claim 9 (depends on 4)

An apparatus according to claim 4, wherein the one or more indicators request the user to provide the one or more user inputs in sequence.

### Claim 10 (depends on 1)

An apparatus according to claim 1, wherein the authorising circuitry is in communication with a secure database comprising biometric data corresponding to the user and the authorising circuitry is configured to authenticate each of the one or more user inputs provided by the user in accordance with the secure database.

### Claim 11

A method of authorising a specific transaction having a requested payment amount, comprising:
receiving, at an apparatus configured to authorise the specific transaction, a request to authorise the specific transaction, the request indicating the requested payment amount of the specific transaction;
receiving, at the apparatus configured to authorise the specific transaction, one or more user inputs required from a plurality of biometric sources of the user;
associating each respective biometric source with a respective numeral according to a predetermined mapping of the biometric sources to one or more numerals;
determining a set of provided numerals based on the biometric sources used for the one or more user inputs;
comparing, at the apparatus configured to authorise the specific transaction, the provided numerals to the requested payment amount;
determining, at the apparatus configured to authorise the specific transaction, whether there is a match between the provided numerals and the requested payment amount; and
in response to the match, asserting by the apparatus configured to authorise the specific transaction, that the specific transaction has been securely authorised by the user; and
when the one or more provided numerals instead match a different requested payment amount from a different transaction, not asserting by the apparatus configured to authorise the specific transaction that the specific transaction was securely authorised by the user,
wherein the user inputs comprise one or more of the following:
a fingerprint of a user detected by one or more sensors to detect;
at least one of a retina and an iris of a user detected by one or more image sensors; and
a voiceprint of a user detected by one or more audio sensors.

### Claim 12

A non-transitory, computer-readable storage device storing software which, when executed by a computer, causes the computer to:
receive, at an apparatus configured to authorise a specific transaction, a request to authorise the specific transaction, the request indicating the requested payment amount of the specific transaction;
receive, at the apparatus configured to authorise the specific transaction, one or more user inputs required from a plurality of biometric sources of the user;
associating each respective biometric source with a respective numeral according to a predetermined mapping of the biometric sources to one or more numerals;
determining a set of provided numerals based on the biometric sources used for the one or more user inputs;
comparing, at the apparatus configured to authorise the specific transaction, the provided numerals to the requested payment amount;
determining, at the apparatus configured to authorise the specific transaction, whether there is a match between the provided numerals and the requested payment amount; and
in response to the match, asserting by the apparatus configured to authorise the specific transaction, that the specific transaction has been securely authorised by the user; and
when the one or more provided numerals instead match a different requested payment amount from a different transaction, not asserting by the apparatus configured to authorise the specific transaction that the specific transaction was securely authorised by the user,
wherein the user inputs comprise one or more of the following:
a fingerprint of a user detected by one or more sensors to detect;
at least one of a retina and an iris of a user detected by one or more image sensors; and
a voiceprint of a user detected by one or more audio sensors.
