    • Digital content management methods and systems are provided. First, device ID of a first electronic device is received, and a data license including at least the device ID of the first electronic device, and a control license including at least a read authorization for a digital content are generated. Then, the digital content and the control license are packed as a content package, and the content package and the data license are respectively transmitted to the first electronic device. An electronic device determines whether the device ID of the electronic device conforms to the device ID recorded in the data license. If so, the digital content in the content package is allowed to be read according to the control license. A new data license is generated for the digital content according to the device ID of a second electronic device. The new data license is stored to the second electronic device, and the data license in the first electronic device is abrogated. Then, the content package is transmitted from the first electronic device to the second electronic device.
    • 提供数字内容管理方法和系统。 首先,接收第一电子设备的设备ID,并且生成至少包括第一电子设备的设备ID的数据许可和至少包括数字内容的读取授权的控制许可。 然后,数字内容和控制许可证被打包为内容包,并且内容包和数据许可被分别发送到第一电子设备。 电子设备确定电子设备的设备ID是否符合数据许可证中记录的设备ID。 如果是这样,可以根据控制许可证读取内容包中的数字内容。 根据第二电子设备的设备ID为数字内容生成新的数据许可。 新的数据许可证被存储到第二电子设备,并且第一电子设备中的数据许可被废除。 然后,将内容包从第一电子设备发送到第二电子设备。
