AUTHENTICATION/SECURITY USING USER ACTIVITY MINING BASED LIVE QUESTION-ANSWERING

A processor-implemented method enables a device based on authentication of a particular user. One or more processors data mine past activities of a particular user. The past activities are detected by physical monitoring devices that monitor the particular user. The processor(s) create an authentication question and answer for the particular user based on the past activities of the particular user that the one or more processors have data mined. The processor(s) receive a request to use an electronic device used by the particular user, and then 1) transmit the authentication question to the electronic device used by the particular user and 2) receive an authentication answer to the authentication question from the electronic device used by the particular user. In response to the authentication answer from the electronic device matching the answer for the authentication question, the processor(s) remotely enable the electronic device for the particular user.
