A mobile device includes a user interface including a display panel to display a menu image and a touch panel to receive a password, a network interface to detect an external device, a functional unit to sense a motion of the mobile device and to photograph a user, and a control unit to control the user interface, the network interface, the memory, and the functional unit, to unlock the mobile device according to a user identification process of identifying an authorized user, when the mobile device is in a time condition, in response to the sensed motion, and to unlock the mobile device according to the password when the mobile device is not in the time condition, in response to the sensed motion.

Improved techniques for facilitating emergency access to one or more contacts stored on a portable electronic device are disclosed. One or more contacts on the portable electronic device are designated as emergency contacts. While the portable electronic device is password-locked, a request to display the one or more emergency contacts on the password-locked portable electronic device is received. Without requiring a password, the one or more emergency contacts are displayed on the portable electronic device.

A method and an apparatus for controlling an operation of a mobile terminal are preferably includes: cancelling a touch screen off mode and checking a set mode mapped to a certain key when input of the certain key is sensed while the mobile terminal is in the touch screen off mode. A screen is then displayed for executing the set mode, and displaying and processing of a signal input through a touch screen is performed. The method and apparatus provide an advantage by reducing procedures required by conventional devices in which a user process to execute a desired mode in a mobile terminal when the mobile terminal is in a touch screen off mode. By registering a function to be executed by input of one touch button key while in a touch screen off mode according to user tastes, the present invention accelerates utilization of the mobile terminal.

Embodiments of the present disclosure disclose a terminal anti-lost method and a terminal, to resolve a problem that a lost terminal is difficult to find when a user discovers in a timely manner that the terminal is lost. The method in the embodiments of the present disclosure includes: first detecting, by the terminal when receiving a specific instruction, whether the terminal is currently in a lock screen state, where the specific instruction represents an instruction of controlling the terminal to decrease volume and/or an instruction of preventing the terminal from receiving a carrier signal; and skipping executing, by the terminal, the instruction when it is determined that the terminal is in the lock screen state, and controlling the terminal to increase the volume and/or play an alarm tone by using a loudspeaker.

Systems and methods are provided for selectively restricting a mobile device. In one implementation, a visual capture can be to identify one or more indicators within the visual capture. Based on the indicators, an implementation of a restriction at the mobile device can be adjusted. In another implementation inputs can be processed to compute a determination, determination reflecting at least one of the in-vehicle role of the user as a driver and the in-vehicle role of the user as a passenger; and, an operation state of the mobile device can be modified based on such a determination. According to another implementation, one or more outputs can be projected from a mobile device, inputs can be received, and such inputs and outputs can be processed to determine a correlation between them. A restriction can then be modified based on the correlation.

A mobile electronic device includes an acceleration sensor configured to detect an acceleration value, a controller configured to determine, based on the acceleration value, movement state of user of the mobile electronic device, a first input unit configured to receive input of information enabling unlocking of a security lock state in which a security lock is effective, and a second input unit configured to receive input of biological information enabling unlocking of the security lock state.

According to one embodiment, a first unlock code is received 420 at a user device 210 from a computer based unlock code generator. The first unlock code is received at a part of receiving a lock command for locking the user device 210. The unlock code generator is not under the control of the user. The first unlock code 212 is stored 430 at the user device 210. A second unlock code, which is provided by the user via a computer based device, is received 440 at the user device 210. The first unlock code 212 and the second unlock code are compared 450 at the user device. The user device is unlocked 460 if the first unlock code 212 is the same as the second unlock code.
