A set of measurement data is gathered by a network-enabled end device over a period of time. A mathematical function is generated to describe behavior of the set of measurement data. A compact, encoded message is generated representing the behavior of the gathered set of measurement data and the compact, encoded message is transmitted for storage in a data store associated with a backend server. Responsive to a received data analysis request, particular compact, encoded messages stored in the data store and applicable to the data analysis request are decoded. Time series data reconstructing the measurement data based on the decoded messages is generated.

Efficiency and performance in Internet-of-Things scenarios

Systems and methods allow service-to-device mapping by which services are mapped onto best-suited smart items selected from a plurality of smart items of a sensor network. As part of the mapping, and/or subsequent thereto, a deployment of the service(s) onto the smart items is initiated. However, in some cases, the deployment may fail, or may only partially succeed. In such cases, one or more conditions of the deployment may be altered to obtain a modified, allowable deployment condition, so that the deployment may then proceed. As a result, users may achieve a desired result in a fast, convenient, and reliable manner, even when executing the deployment remotely or automatically.

Active intervention in service-to-device mapping for smart items

The present application relates to a method for transferring data, a computer program product, a data provision device, a data receiving device and a communication system, in particular to authentication/verification of data provided between one or more radio frequency identification reader(s) and one or more radio frequency identification transponder(s). In some embodiments, the method includes an initializing step and a data provisioning step.

Method for transferring data, a computer program product, a data provision and a data receiving device and a communication system

Systems and methods are described that provide a system monitor component, e.g., for a sensor network, which may include, e.g., a server component that is continuously running and monitoring zero or more networks consisting of (possibly wireless) devices, where each network may be executing a different communications protocol, such as a proprietary, platform-dependent protocol. The system monitor may maintain a system model of the networks. The system monitor may be connected with the networks through a message transport system that routes any occurring messages in a common or standard communications protocol, as well as message handlers that access either platform-abstracting gateways or the proprietary messages that the devices of one or more of the networks may use.

System monitor for networks of nodes

An identification tag for authenticating a product is associated with the product and has authentication data transmissible to a reader device. The authentication data include source data including a tag identifier that uniquely identifies the identification tag and a signature value that is a result of a private key encryption of a representation of the source data, where the private key encryption uses a private key of a public key encryption method.

Authentication of products using identification tags

A service repository is used to store at least one service in association with service metadata describing service requirements of the service. The service repository also may store one or more platform-specific service executables. A service mapper is used to determine device metadata associated with each of a plurality of devices, where the device metadata provides device characteristics of the devices. The service mapper may thus map the service to a selected device of the plurality of devices for deployment thereon, based on a matching of corresponding elements of the service requirements and the device characteristics. The service mapper also may re-map the service between devices to maintain a quality and reliability of the service.

Service-to-device re-mapping for smart items

A provider system is disclosed for providing a sequence of public keys to a receiver system, wherein each public key of the sequence is related to a private key and is applicable for a public key cryptography procedure. The provider system can include a computing unit and a sending unit. The computing unit can be configured to generate the sequence of public keys and related keys and compute a plurality of data sets, where a data set of the plurality of data sets includes a public key and a proof value. The proof values can result from applying a hash function to a following data set that includes a further public key following in the sequence. The sending unit can be configured to provide the plurality of data to a receiver system.

System and method for updating keys used for public key cryptography

A quality of service parameter associated with message traffic transmitted from a smart items infrastructure through a middleware message routing engine to one or more enterprise applications is monitored. In response to the monitored quality of service parameter, a number of parallel message processors that route messages from the plurality of smart items to the message routing engine is controlled.

Method and system to adaptively manage the quality of service of interactions between smart item networks and enterprise applications

An embodiment includes a prediction system for initiating a data transfer to a decision system. The prediction system is configured to identify a decision, the decision being a result of a computation of the decision system according to a set of predefined rules and input data. The prediction system is further configured to identify predicted input data representing a portion of the input data and to initiate a transfer of the predicted input data to the decision system prior to the computation of the decision.
