    Abstract: A cloud service system includes a server and a first cloud service platform. The server stores a service program. The first cloud service platform is in communication with the server and includes a first service index, a first communication control processing module, a first temporary data storage module and a first registration module. When a client device requests the first cloud service platform for a service, the first communication control processing module determines whether the first temporary data storage module stores the service program, and if the first temporary data storage module does not store the service program, the first communication control processing module obtains the service program from the server by using a first link path preset in the first service index, executes the service program obtained from the server for providing a cloud service to the client device, and stores the service program into the first temporary data storage module.

    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.
