Abstract: A method and apparatus for synchronizing a system time in an electronic device are provided. The method may include: when the electronic device is executing a boot process, disabling an external time obtaining function of the electronic device for obtaining an external reference time, obtaining an internal clock time from an internal clock unit of the electronic device and synchronizing a system time of the electronic device with the internal clock time; and when the electronic device has completed the boot process, enabling the external time obtaining function to obtain the external reference time.

Abstract: Technologies are generally described related to remotely retrieving information from a mobile device. One example method for distributing information via a mobile network may include receiving, by a first mobile device from a second mobile device, a data request for a first set of information, wherein the data request includes a passcode. The example method may include authenticating the second mobile device using the passcode, and sending the first set of information stored on the first mobile device to the second mobile device via the mobile network.

Abstract: In accordance with embodiments of the present disclosure, a method for marking an image projected onto a surface includes capturing a second image from the surface, detecting the existence of a marking point in the second image, and modifying the first image by placing a graphic element at a location corresponding to a location of the marking point in the second image.

Abstract: A system and method for securing contents displayed on a display device, and a device for viewing displayed content are provided. The system may include a first device and a communication module. The communication module may be adapted to communicatively connect the first device to the display device. The first device may be adapted to control, via the communication module, the display device to alternately display a first content and a second content. The second content may contain interference information. The device for viewing displayed content may be adapted to alternately let light through and shut off light. With the device for viewing displayed content, the first content displayed is viewable by an intended viewer while the second content displayed is un-viewable by the intended viewer.
