The invention provides a light management information system for an outdoor lighting network system, having a plurality of outdoor light units each including at least one sensor type, where each of the light units communicates with at least one other light unit, at least one user input/output device in communication with at one or more of said outdoor light units, a central management system in communication with light units, said central management system sends control commands and/or information to one or more of said outdoor light units, in response to received outdoor light unit status/sensor information from one or more of said outdoor light units or received user information requests from said user input/output device, a resource server in communication with said central management system, wherein the central management system uses the light unit status/sensor information and resources from the resource server to provide information to the user input/output device and/or reconfigure one or more of the lights units.

This invention provides a method for managing a transaction right in a digital rights management server. The transaction right is the right to a transaction of a utilization right of a digital content item. The method comprises steps of obtaining an attribute associated with the digital content item from metadata of the digital content item; and generating the transaction right on the basis of a pre-stored rule and the attribute of the digital content item. Since the transaction right is generated on the basis of the attribute of the digital content item, or in other words, the transaction right is dependent on the attribute of the digital content item, the generated transaction right of digital content items can be different if the corresponding attribute associated with the digital content items are different. Furthermore, in additional to the metadata, the generation of the transaction right only requires the pre-stored rule, resulting in affordable complexity and cost. Since the transaction right is also dependent on the pre-stored rule, the content providers need not to individually set the transaction right for each digital content item, but are still able to set the transaction right by setting the pre-stored rule.

The present invention relates to a method and apparatus for controlling a handshake operation. Datagram Transport Layer Security (DTLS) is an important secure protocol in the IP based Internet of things. The performance of DTLS handshake can be significantly affected by network status, traffic and packet loss rate, etc. It is therefore suggested evaluating a package loss rate and estimating causes of packet loss. Then, a DTLS handshake strategy may be changed adaptively based on the detection of packet loss and network status. As a result, the successful rate and delay of DTLS handshake can be improved. An acknowledgement and a non-acknowledgement mode may be used in a hybrid way to evaluate the package loss rate and estimate causes of packet loss and eventually improve performance of DTLS handshake.

The invention relates to a method for enabling a controller configured for controlling devices of a first system via a first backend to control devices of a second system via a second backend. The method, performed by the second backend, includes receiving, from the first backend, location information of the controller and credentials of the controller or/and of a user of the controller, receiving, from a source trusted by the second backend, location information of the controller and credentials of the controller or/and of the user, and performing context matching to enable the controller to control the devices of the second system by comparing the location information received from the first backend with the location information received from the source trusted by the second backend and by comparing the credentials received from the first backend with the credentials received from the source trusted by the second backend.

Context-aware controlling of multiple systems of controllable devices

The present invention relates to a method for access decision evaluation in a building automation and control system, the method comprising: sending, from an accessing device () to an accessed device (), an access request, sending, from the accessed device () to a central decision evaluation apparatus (), an evaluation request asking if the access request is granted or denied, evaluating, at the central decision evaluation apparatus (), the evaluation request using one or more central access control policies in order to reach a decision on if the access request is granted or denied, deriving, at the central decision evaluation apparatus (), the one or more central access control policies that was used for evaluation into a device specific access policy, sending, from the central decision evaluation apparatus () to the accessed device (), the decision and the device specific access policy, and storing, at the accessed device (), the device specific access policy.

A method and a system are provided for monitoring a lighting system. Physical location information is received with respect to each lighting unit of the system. Supply voltage information is also received with respect to each lighting unit. Based on the physical location of each lighting unit and the supply voltage information, power network information is derived to identify cable routes between the lighting units and the locations of lighting cabinets along the cable routes.

The invention proposes methods and devices for managing domains. The domains comprise a plurality of member devices, and the method comprises the steps of: storing (S, S), by a first domain manager (M), domain management information (P, P, P, Pand P) in said plurality of member devices; and obtaining (S, S), by a second domain manager (M), said domain management information from at least one of said plurality of member devices. In comparison with the prior art, where the domain management information is maintained in the domain authority, the embodiment decreases the work load of the domain authority and provides conveniences.

A method of rights management in a first device connected to digital data content, said first device comprising a right for accessing said digital data content and available state information for reflecting the state of use of said digital data content, said method comprising the steps of: &#x2014;receiving by said first device a request for a state information from a second device; &#x2014;comparing the content of said request with said available state information; &#x2014;selecting said requested state information in said available state information according to the result of said comparing step; &#x2014;transferring said requested state information to said second device via a communication channel; and&#x2014;duplicating said fight to said second device.

Method and device for rights management

The present invention provides a method for authenticating the copy right of a device by an offline way, a digital right protection system, and a method for providing digital contents, which mainly includes embedding an authentication agent into the digital content, said authentication agent, instead of the copyright issuer at the server side, authenticates the rendering qualification of the device before rendering the digital content. If the device is a non-compliant device, the authentication agent will not permit the device to render the digital content. The technique of the invention realizes offline digital right management, so it is not restricted by the network condition and can be applied widely in various environments.

Device and method for digital right management

The invention provides a method and devices for managing digital content, the method comprising the steps of sending, by a first device (), an encrypted content key () to a second device (); sending, by said second device () to a third device (), a license data describing the rights to use said digital content by said third device () in response to a request from said third device () to use said digital content, wherein said license data includes said encrypted content key (); and receiving, by said third device () from said first device (), data for decrypting said encrypted content key ().
