Physiological response PIN entry

1. A system comprising:

a memory storing account information for a plurality of users, the account information including a personal identification number (PIN) for at least some of the users;

a processor operable to:

receive a communication including an indication of a desire of a user to authorize a transaction or log into an account;

access an account of the user;

provide a plurality of random sequences of numbers to the user, wherein each number of the random sequence of numbers is highlighted for a predetermined duration of time;

receive timing information indicative at what time a physiological response consisting of a blink or wink or smile or frown or subtle facial movement was provided when a user was viewing the random sequences while each individual number was being highlighted for the predetermined duration of time;

determine which number was selected using the timing information when numbers in the random sequence were highlighted and the timing information when the physiological response was provided;

make a reconstructed PIN from the random sequences and the timing information; and

authorize the transaction if the reconstructed PIN is the PIN of the user.

2. The system of claim 1 , wherein the random sequences each comprise a set of numbers from 0 to 9 in random order.

3. The system of claim 2 , wherein a different random sequence is provided for each number in the PIN of the user.

4. The system of claim 2 , wherein the set of numbers is configured by the processor for display in a one dimensional configuration.

5. The system of claim 2 , wherein the set of numbers is configured by the processor for display in a two dimensional configuration.

6. The system of claim 2 , wherein each number of the set of numbers is configured by the processor to have a random horizontal position and a random vertical position.

7. The system of claim 1 , wherein the processor controls which number of the random sequence of numbers is indicated by a highlight.

8. The system of claim 1 , wherein the processor is operable to define a random starting position of a highlight each time the random sequence is provided.

9. The system of claim 1 , wherein the PIN comprises at least one of letters, symbols, images, and numbers.

10. A method comprising:

storing, in a memory, account information for a plurality of users, the account information including a personal identification number (PIN) for at least some of the users;

receiving, electronically by a processor, a communication including an indication of a desire of a user to authorize a transaction;

accessing, by the processor, an account of the user;

providing, by the processor, a plurality of random sequences of numbers to the user, wherein each number of the random sequence of numbers is highlighted for a predetermined duration of time;

receiving, electronically by the processor, timing information indicative at what time a physiological response consisting of a blink or wink or smile or frown or subtle facial movement was provided when a user was viewing the random sequences while each individual number was being highlighted for the predetermined duration of time;

determining by the processor which number was selected using the timing information when numbers in the random sequence were highlighted and the timing information when the physiological response was provided;

making, by the processor, a reconstructed PIN from the random sequences and the timing information; and

authorizing, by the processor, the transaction if the reconstructed PIN is the PIN of the user.

11. The method of claim 10 , wherein the random sequences each comprise a set of numbers from 0 to 9 in random order.

12. The method of claim 11 , wherein a different random sequence is provided for each number in the PIN of the user.

13. The method of claim 11 , wherein the set of numbers is configured by the processor for display in a one dimensional configuration.

14. The method of claim 11 , wherein the set of numbers is configured by the processor for display in a two dimensional configuration.

15. The method of claim 11 , wherein each number of the set of numbers is configured by the processor to have a random horizontal position and a random vertical position.

16. The method of claim 10 , wherein the processor controls which number of the random sequence of numbers is indicated by a highlight.

17. A computer program product comprising a non-transitory computer readable medium having computer readable and executable code for instructing a processor to perform a method, the method comprising:

storing, in a memory, account information for a plurality of users, the account information including a personal identification number (PIN) for at least some of the users;

receiving, electronically by a processor, a communication including an indication of a desire of a user to authorize a transaction;

accessing, by the processor, an account of the user;

providing, by the processor, a plurality of random sequences of numbers to the user, wherein each number of the random sequence of numbers is highlighted for a predetermined duration of time;

receiving, electronically by the processor, timing information indicative at what time a physiological response consisting of a blink or wink or smile or frown or subtle facial movement was provided when a user was viewing the random sequences while each individual number was being highlighted for the predetermined duration of time;

determining by the processor which number was selected using the timing information when numbers in the random sequence were highlighted and the timing information when the physiological response was provided;

making, by the processor, a reconstructed PIN from the random sequence and the timing information; and

authorizing, by the processor, the transaction if the reconstructed PIN is the PIN of the user.
