Abstract
Secure communication of user inputs is achieved by isolating part of an endpoint device such that certificates and encryption keys are protected from corruption by malware. Further, the communication is passed through a trusted data relay that is configured to decrypt and/or certify the user inputs encrypted by the isolated part of the endpoint device. The trusted data relay can determine that the user inputs were encrypted or certified by the protected certificates and encryption keys, thus authenticating their origin within the endpoint device. The trusted data relay then forwards the inputs to an intended destination. In some embodiments, the isolated part of the endpoint device is configured to detect input created by auto-completion logic and/or spell checking logic.
