Claims28
A method of installing a content protection system in a device for using digital content in the device, the method comprising:
- transmitting a request for the content protection system required for decrypting the digital content in the device based on a type of a protection technology applied to the digital content;
- receiving the content protection system, based on the type of the protection technology applied to the digital content, from an external apparatus;
- and
- installing the received content protection system in a storage unit of the device.
A method of allowing installation of a content protection system for using digital content, the method, performed by a server, comprising:
- receiving a request for the content protection system required for decrypting the digital content in a device based on a type of a protection technology applied to the digital content;
- receiving first security information of the device;
- comparing the received first security information with second security information related to a security level required by the content protection system;
- and
- transmitting the content protection system according to a result of the comparing.
An apparatus for playing digital content, the apparatus comprising:
- a content protection system request unit which transmits a request for content protection system required for decrypting the digital content in the device based on a type of a protection technology applied to the digital content;
- a content protection system reception unit which receives the content protection system based on the type of the protection technology applied to the digital content, from an external apparatus;
- and
- a content protection system storage unit in which the received content protection system is installed.
