Abstract: 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.
