Abstract: In a method of protecting copyright of a digital media file in an electronic device, the electronic device receives a request for downloading the digital media file, from a recipient electronic device, the electronic device requires the recipient electronic device, to provide information of the recipient electronic device, the electronic device further requests a third-party authorization system, to allocate a key for the digital media file according to the information, once the electronic device locks the digital media file using the key, the electronic device sends the locked digital media file to the recipient electronic device.

Abstract: In a near-field communication (NFC) service protection method of the mobile device, the mobile device includes an NFC controller, one or more security elements, a global positioning system (GPS) and a storage system. The method sets a security code for an NFC service of each of the security elements according to the geographic location of the mobile device as acquired by the GPS, and stores a security protection of the NFC service corresponding to each of the NFC services into the storage system. After an NFC service is selected from one of the security elements, and the NFC service is performed by executing an NFC application corresponding to the NFC service through the NFC controller. In addition, the method deletes the security code of the NFC service to disable the security protection of the NFC service when the NFC service needs to disable the security protection.

Abstract: A method for generating one-time password (OTP) using a mobile phone registers a telephone number of the mobile phone on a website at first. A communication server generates a first random number and a second random number. Furthermore, the communication server generates a first OTP according to the first random number, and a subscriber identity module (SIM) card of the mobile phone generates a second OTP according to the second random number. The communication server checks if the second OTP is the same as the first OTP. If the second OTP is the same as the first OTP, the mobile phone has successfully logged onto the website.

Abstract: A system and method for displaying characters on a BLUETOOTH device using a mobile electronic device obtains a telephone number of an incoming call, and converts associated one or more characters into a bitmap picture in response to a determination that the telephone number is associated with one or more characters in a character encoding packet. The system and method further reads a resolution of the bitmap picture and a resolution of a display of the BLUETOOTH device, and adjusts the resolution of the bitmap picture to match the resolution of the display of the BLUETOOTH device. Furthermore, the system and method sends the bitmap picture or the telephone number to the BLUETOOTH device, and displays the bitmap picture on the display of the BLUETOOTH device.
