Functionality is disclosed for enhancing the security of a computing device equipped with a fingerprint input device. A pre-unlock operation is performed when a duress fingerprint is used to access a locked device. The pre-unlock operation may include one or more computer-implemented mechanisms to secure, hide, remove, move, encrypt, disassociate, communicate or modify data stored on the device and/or remote locations. In some embodiments, the pre-unlock operation may direct a device to capture information and communicate such information to remote computers contemporaneously with the receipt of a duress fingerprint.
