System and method for selective encryption of input data during a retail transaction
First Claim
1. A method of collecting information at a retail terminal, comprising:
- determining whether content to be presented on a display of the retail terminal requests information;
if the content to be presented on the display requests information, determining whether the content requests sensitive information;
authenticating the content to be presented on the display;
presenting the content on the display if the content is authenticated; and
if the content requests sensitive information, encrypting data received from one or more data entry point devices for transmission to a location removed from the retail terminal.

Abstract
A retail environment having retail terminals with data entry point devices selectively encrypts input received by the data entry point devices and passes the encrypted data to a security module. The selective encryption is based on whether or not sensitive or confidential information, such as a personal identification number (PIN) associated with a debit card, is being input. To prevent hacking of the software of the retail terminal, content destined for display on the retail terminal is authenticated prior to display. In this manner, the retail terminal may be assured that confidential information is input only when desired, and thus may be encrypted only as needed.
