Abstract
A security question generation instruction is sent by a server to a user device. A reference picture is received at the server from the user device, where the reference picture is generated by the user device based on the security question generation instruction. A number of confusion pictures corresponding to the reference picture are determined by the server. A security question is generated by the server based on the reference picture and the plurality of confusion pictures.
