摘要： Systems and methods which provide for auditable data are described. Data management systems of embodiments facilitate storage and management of various data (e.g., information regarding transactions, customers, infrastructure, geographic locations, medical records, etc.) for supporting data creation, manipulation, storing, and/or sharing by and among different parties. Users may create new and/or update data, digitally sign the data, and store the digital signature and data on immutable storage using data structures of a data management system. A data structure in which data and associated metadata is stored on immutable storage in association with a digital signature corresponding to the data and user may be used in providing data traceability and auditability. Snapshots of merged data may be implemented with respect to data having many updates to avoid delays in merging update data for queries for that data. A collaborative rating mechanism may provide trust levels with respect to the data.

摘要： Systems and methods which provide data exchange using a distributed ledger, wherein data is exchanged off-chain and information for accessing the off-chain data is exchanged through the blockchain, are disclosed. Embodiments may provide a hybrid blockchain data exchange platform storing large amounts of data (e.g., IoT data) in a data server outside of the blockchain, wherein a data consumer may obtain data from the data server using a token obtained from the blockchain. Embodiments of a hybrid blockchain data exchange platform provide for accuracy and security of the data without requiring storage of the full contents of the data within the blockchain, and/or provide data exchange in which the irrefutability of the data exchanged is ensured.

摘要： Systems and methods providing synchronization of wireless device data based upon device synchronization prioritization determinations are described. Embodiments may make device synchronization prioritization determinations using device grouping identifiers with respect to a plurality of wireless devices and/or one or more device synchronization parameters for the wireless devices. Logic of a synchronization prioritization gateway of embodiments may implement a prioritization determination algorithm to determine a sequence of wireless devices for data synchronization for facilitating data synchronization with respect to a plurality of wireless devices in a timely and efficient manner. The logic of the synchronization prioritization gateway may implement a priority penalty attribute with respect to particular wireless devices to address aberrant behavior or other operation likely to impede efficient and/or timely data synchronization.

摘要： The present disclosure is related to a system for managing data exchanges between Bluetooth Low Energy (BLE) devices. The system includes a plurality of BLE devices. At least one BLE device is configured as a parent node and at least one BLE device is configured as a child node. The parent node is configured to receive a BLE packet, including data reported by the child node in a payload field of the BLE packet, and to use a location function to determine a location in the payload field for inserting data to be reported from the parent node. The parent node aggregates the data to be reported from the parent node and the data reported by the child node by inserting the data from the parent node into the determined location in the payload field of the BLE packet, and then broadcasts the BLE packet with the aggregated data.
