摘要:
A method and device for enforcing advertisement viewing in the device are provided. When there is a play request for contents, it is determined whether there is a common Rights Object (RO) linked with an RO of the requested contents. When there is a common RO, information about consumption of advertisements on a plurality of contents is obtained from the common RO. At least one advertisement linked with the requested contents is played on the basis of the obtained information.
摘要:
An encryption key distribution method for service and content protection in a mobile broadcasting system, and a system for the same which includes generating, by a network, a first encryption key when the broadcast service is first provided; transmitting a generalized rights object message, which includes identification information for identifying the generated first encryption key, to the terminal; generating a second encryption key before the lifetime of the first encryption key expires; and transmitting the generalized rights object message, which includes identification information for identifying the generated second encryption key, to the terminal.
摘要:
A system and method for managing an encryption key are provided, which include receiving, from a DRM agent, an RO request message for receiving content; generating a KSP including a first key and a second key; applying hash chains with different directions to the first key and to the second key to generate an encryption key for the content; and transmitting, to the DRM agent, a response message including a context element having an identifier of the content and a key information element. The key information element includes a first encryption key element; a rights encryption key information element; and an encryption data element.
摘要:
A method and a system for distributing an encryption key for service protection and content protection in a mobile broadcasting system are provided where a network generates a first encryption key when a broadcasting service is first provided to the terminal, and transmits a long term key message including the generated first encryption key to the terminal. Also, the network generates a second encryption key before the lifetime of a first access value pair expires, and transmits a long term key message including the generated second encryption key to the terminal.

摘要:
A method for protecting personal information in Audience Measurement (AM) of a digital broadcasting system is provided, including inserting an indicator, which notifies whether a consumption pattern of a service or content provided by a service provider can be measured, into a service guide, to which the information of the service or content is provided by a service provider; and determining whether the AM can be executed for the service or content in accordance with the indicator when the AM function is implemented in a terminal.
摘要:
A method and apparatus for managing tokens for Digital Rights Management (DRM) in a terminal are provided. In the method, at least one token is acquired from a Rights Issuer (RI), and the token is moved to a Secure Removable Media (SRM) through a token move request message. The token can be shared by several terminals.
摘要:
A method and apparatus for providing a broadcast service in a communication system is provided. The method includes creating a seed key pair including a first key and a second key, transmitting the seed key pair to a terminal to which the broadcast service is to be provided, creating a certain number of encryption keys using the seed key pair, the certain number corresponding to a lifetime of the seed key pair, encrypting broadcast service data for the lifetime using the encryption keys, and broadcasting the encrypted broadcast service data.
摘要:
A method and apparatus for reporting a consumption time of a service or content in Audience Measurement (AM), which measures a user consumption pattern of the service or the content is provided. A method for reporting a consumption time of the service or the content in a terminal of a content transmission system includes receiving an encryption key for encrypting the service or the content from a broadcasting server and transmitting a message requesting interpretation of the encryption key to a smart card. The message includes consumption time information of the service or the content.
摘要:
Methods and apparatus for providing a multimedia service are provided. A first request message is transmitted from the device to a rights issuer requesting a first right object required to execute an advertisement. A first request response message having the first right object is transmitted from the rights issuer to the device. The advertisement is executed at the device using the first right object. A report message having an advertisement consumption specification is transmitted from the device based on execution of the advertisement. A report response message having an advertisement consumption certificate is received at the device. A second request message is transmitted from the device to the rights issuer requesting a second right object required to execute the content. A second request response message having the second right object is transmitted from the rights issuer to the device, when the second request message includes the advertisement consumption certificate.
