Abstract: In a method of switching a locked state of an electronic device with a user-verifying function, a biologic feature data from a user is captured while receiving an input from the user for an operation when the electronic device is in a locked state. Whether the biologic feature data conforms to a reference biologic feature data is then determined. If it is determined that the biologic feature data conforms to the reference biologic feature data, the electronic device is switched from the locked state into a non-locked state and directly controls the electronic device to perform the operation according to the input when the biologic feature data is determined conforming to the reference biologic feature data.
