Continuous User Authentication Criteria for Access to Encrypted Files

Methods and systems provide for multi-factor authentication (MFA) of a user to a device or network in which continuous user authentication criteria is used to determine access to encrypted files. After the user is authenticated and provided with access, a continuous user authentication criteria must be fulfilled for that access to the encrypted file to be maintained. When it is determined that the criteria is not satisfied, access to the encrypted file is denied. The criteria may be based on the location of a second computing device with respect to a first computing device. Multiple methods of determining continuity may be employed simultaneously, with access being denied when continuity is fulfilled by none of the methods.
