Abstract
Techniques for encrypting keyboard data prior to its being received by an operating system of an endpoint device, reducing the possibility of unencrypted keyboard data being logged by a keylogger application running on the endpoint device. The techniques employ an encryption filter communicably coupled between a keyboard and the endpoint device. The encryption filter receives unencrypted keyboard data from the keyboard, encrypts the keyboard data, and provides the encrypted keyboard data to the operating system of the endpoint device. The techniques can be employed in association with a back-end data processing center of a security standard compliant organization, which can receive the encrypted keyboard data from the endpoint device, and decrypt the keyboard data for use on a host system. In this way, access and/or storage of unencrypted keyboard data at the endpoint device can be avoided.
