capturing, by a processor, at least one of a physiological and a psychological response from a customer at a transaction terminal for purchase of a product;

capturing, by the processor, measurement information of the product;

storing, in memory via a processor, the captured measurement information of the product;

determining, by the processor, a biometric characteristic of the customer based on the at least one of the physiological and the psychological response of the customer;

determining, by the processor, an honesty level of the customer based on an analysis of the biometric characteristic;

verifying, by the processor, whether the honesty level of the customer meets a predetermined honesty level;

adjusting, by the processor, a security level of the transaction terminal based on the biometric characteristic of the customer and whether the honesty level of the customer meets the predetermined honesty level;

retrieving, from the memory via the processor, expected measurement information of the product stored in memory;

determining, by the processor, a tolerance range and a match level of the product based on the biometric characteristic of the customer, a comparison between the retrieved expected measurement information and the captured measurement information from the product;

increasing, by the processor, the match level when comparing the retrieved expected measurement information and the captured measurement information from the product;

and

deactivating, by the processor, the transaction terminal when the match level is outside the tolerance range.

2. The method of claim 1 , wherein the at least one of the physiological and the psychological response is a measure of at least one of a speech pattern, eye movement, facial movement, heart rate, blood pressure, body temperature, and perspiration of the customer.

3. The method of claim 1 , further comprises:

evaluating, by the processor, the customer;

presenting, by the processor via a user interface, at least one question to the customer; and

receiving a response of the customer to the at least one question, and

analyzing the biometric characteristic based on the response of the customer.

4. The method of claim 3 , wherein the transaction terminal comprises at least one of a touch, visual, and audio sensor, and

wherein evaluating a customer at the transaction terminal comprises using the at least one of the touch, visual, and audio sensor to evaluate the customer.

5. The method of claim 4 , further comprising displaying an image at the transaction terminal, and

wherein determining a biometric characteristic of the customer comprises using the at least one of the touch, visual, and audio sensor to determine the honestly level of the customer in response to displaying the image at the transaction terminal.

6. The method of claim 1 , wherein adjusting a security level of the transaction system comprises adjusting the security level of the transaction system to one of a plurality of security levels that are each associated with at least one biometric characteristic.

7. The method of claim 6 , further comprising implementing a predetermined action in response to adjusting the security level.

8. The method of claim 7 , further comprises adjusting product checkout criteria of the transaction terminal.

9. The method of claim 1 , further comprising determining a biometric characteristic history of the customer based on a plurality of interactions with the customer.

10. The method of claim 9 , wherein adjusting a security level of the transaction system comprises adjusting the security level of the transaction system based on the biometric characteristic history.

11. A system comprising:

a processor and memory;

a user interface of a transaction terminal that interacts with a customer for purchase of a product; and

a security module, which when executed by the program code stored in memory, instructs the processor to:

capture at least one of a physiological and a psychological response from a customer at a transaction terminal for purchase of a product;

capture measurement information of the product;

store the captured measurement information of the product;

determine a biometric characteristic of the customer based on the capture of at least one of the physiological and the psychological response of the customer;

determine an honesty level of the customer based on an analysis of the biometric characteristic;

verify whether the honesty level of the customer meets a predetermined honesty level;

adjust a security level of the transaction terminal based on the biometric characteristic of the customer and whether the honesty level of the customer meets the predetermined honesty level;

retrieve expected measurement information of the product stored in memory;

determine a tolerance range and a match level of the product based on the biometric characteristic of the customer, a comparison between the retrieved expected measurement information and the captured measurement information from the product;

increase, by the processor, the match level when comparing the retrieved expected measurement information and the captured measurement information from the product;

and

deactivate the transaction terminal when the match level is outside the tolerance range.

12. The system of claim 11 , wherein the at least one of the physiological and the psychological response is a measure of at least one of a speech pattern, eye movement, facial movement, heart rate, blood pressure, body temperature, and perspiration of the customer.

13. The system of claim 11 , wherein the security module is configured to control the user interface to:

present at least one question to the customer; and

receive a response of the customer to the at least one question, and

wherein the security module is configured to determine a biometric characteristic based on the response of the customer.

14. The system of claim 11 , wherein the user interface of the transaction terminal comprises at least one of a touch, visual, and audio sensor for interacting with the customer.

15. The system of claim 14 , wherein the security module is configured to control the user interface to display an image at the transaction terminal to invoke a response from the customer, and

wherein the security module is configured to create the biometric characteristic of the customer using the at least one of the touch, visual, and audio sensor to determine the honesty level of the customer in response to displaying the image at the transaction terminal.

16. The system of claim 11 , wherein the security module is configured to adjust product checkout criteria of the transaction terminal in response to adjusting the security level.

17. A computer program product for adjusting a security level of a transaction system, said computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising instructions to:

capture at least one of a physiological and a psychological response from a customer at a transaction terminal for purchase of a product;

capture measurement information of the product;

store the captured measurement information of the product;

determine a biometric characteristic of the customer based on the capture of at least one of the physiological and the psychological response of the customer;

determine an honesty level of the customer based on an analysis of the biometric characteristic;

verify whether the honesty level of the customer meets a predetermined honesty level;

adjust a security level of the transaction terminal based on the biometric characteristic of the customer and whether the honesty level of the customer meets the predetermined honesty level;

retrieve expected measurement information of the product stored in memory;

determine a tolerance range and a match level of the product based on the biometric characteristic of the customer, a comparison between the retrieved expected measurement information and the captured measurement information from the product;

increase, by the processor, the match level when comparing the retrieved expected measurement information and the captured measurement information from the product;

and

deactivate the transaction terminal when the match level is outside the tolerance range.

18. The computer program product of claim 17 , wherein the computer readable program code comprises:

computer readable program code configured to present at least one question to the customer at the user interface;

computer readable program code configured to receive a response of the customer to the at least one question; and

computer readable program code configured to determine the biometric characteristic based on the response of the customer.
