  • Publication number: 20130333049
    Abstract: A data protection method for a portable electronic device and a computer program product for the same are applicable to a portable electronic device operating on a Linux operating system. A storage region of the portable electronic device is partitioned to provide a specific partition for storing data to be protected. The specific partition will be mounted, and the data to be protected will be displayed, only if the data to be protected contains an execution command, otherwise the specific partition will be unmounted. Hence, the specific partition is only available when it is confirmed that the data to be protected contains an execution command. Accordingly, unspecific commands, such as file browsing, cannot enable the mounting of the specific partition, thereby hiding the specific partition and enhancing the security of the data to be protected.

  • Publication number: 20130144456
    Abstract: A method for starting an application smartly and power-efficiently is applicable to a portable electronic device installed with an application and hardware. The portable electronic device receives a voltage generated from a power supply, such as an internal battery power or an external power. After the portable electronic device has started, a connection between the application and the hardware is created. Upon detection that the voltage originates from the external power, the application is executed based on a preset schedule to start the hardware corresponding to the application until it is detected that the source of the voltage has been switched to the internal battery power. Upon the detection that the source of the voltage has been switched to the internal battery power, a user determines whether to change the state of use of the hardware, thereby rendering the portable electronic device smart and power-efficient.

  • Patent number: 7953224
    Abstract: A method and system for encrypting a video compressed with MPEG-4 FGS compression with minimal overhead is provided. The encryption system encrypts the video into independently encrypted segments that can be either a video packet or a video block. When the encryption system encrypts based on video packets, it encrypts the data to ensure that the encrypted data does not emulate any video packet delimiting markers. When the encryption system encrypts based on video blocks, it encrypts the coded bitstream for each video block independently, from the most significant bitplane to the least significant bitplane, using either a stream or a block cipher. After all the video blocks are independently encrypted, the encryption system partitions the encrypted data into video packets and adds a buffering bit, if necessary, to prevent emulation of video packet delimiting markers. The encryption system may generate an initialization vector for each independently encrypted segment.
