摘要:
A service provider node 101, and a method therein, for transmitting data packets relating to parts of a service to a communication device 102. The service provider node and the communication device are communicatively connected over a communications network 104 and comprised in a communications system 100. The method comprises receiving 205,302 a signal S1, which signal comprises an identifier of the communication device requesting a service, an identifier of the requested service, and an agreement comprising information about a previously agreed part of the service. The method comprises further agreeing 303 on an upcoming part of the service requested by the communication device, while transmitting 206,304 data packets relating to the previously agreed part of the service to the communication device, wherein the data packets are transmitted in dependence of the received signal.
摘要:
A method for imposing one or more usage constraints on digital content, the method comprising communicating a digital content data item to a digital content receiver system; wherein the digital content data item includes the digital content and a usage constraint data item different from a digital license data item, or a reference to said usage constraint data item, the use case item being indicative of the one or more usage constraints.
摘要:
A method in a first device for anonymously delivering data to a part that has initiated a task is provided. The first device and the part initiating a task are participants in opportunistic sensing. The method comprises creating a data sample and encrypting the data sample with a public key of the task initiating part. After communicating the protected sample to one or more intermediate devices, one of the one or more intermediate devices delivers the protected sample to the task initiating part, such that the task initiating part does not know the identity of the first device. The task initiating device only know the identity of the one of the one or more intermediate devices that delivered the protected sample to the task initiating part, wherein the intermediate devices are participants in the opportunistic sensing.
摘要:
A method for establishing a secured communication channel, between a first processing component and a second processing component; the method comprising executing a digital rights management agent on a processing unit, the digital rights management agent being configured to enforce permissions associated with digital content based on a digital rights management protection mechanism; receiving, by the digital rights management agent at least a security data item, the security data item including a session key data item; verifying authenticity of the received session key data item by the digital rights management agent using said digital rights management protection mechanism; providing the verified session key data item by the digital rights management agent to at least the second processing component; establishing a secured communication channel between the first and second processing components using at least the provided session key data item.
