Abstract
Systems and methods for protecting data stored on an electronic device from access by an illegitimate user are presented. The data is protected by activating an offline data delete module installed in the electronic device to conditionally delete the data according to the following criteria: after establishing a first communication between an agent installed in the electronic device and a remote server, obtaining a password from a user if a second communication is not established between the agent and the remote server within a predetermined period of time. After obtaining a password from the user, deleting at least some data stored on the electronic device after a second communication is not established between the agent and the remote server within the predetermined period of time and a predetermined number of incorrect passwords has been obtained.
