Summary:
|
There are many Internet of things (IoT) platforms to process and manage same IoT data in different stages and in different areas. In traditional solutions, each of the IoT platforms usually stores its activity logs for IoT data processing and management (IoT DPM) into its storage separately. Those activity logs are separated and managed by the IoT platforms. Therefore, the accessibility and trustworthiness of those activity logs are not guaranteed and it is not easy to trace activities about IoT DPM in the full lifecycle for activity logs that are stored and managed by different IoT platforms.
In order to trace activities about IoT DPM, different IoT platforms may use the same activity log storage and related functionalities. Activity log management (ALM) enabled by blockchain technologies provides functionalities to manage activity logs for IoT DPM in the full lifecycle across IoT platforms. Different IoT platforms can individually save activity logs of IoT DPM into trustworthy shared storage via the ALM for IoT DPM. When they read activity logs of IoT DPM via the ALM, they can obtain all the relevant activity logs of IoT DPM in the full lifecycle from the trustworthy shared storage via the ALM for IoT DPM, if authorized. The ALM and the trustworthy shared storage are based on blockchain technologies and can protect the activity logs from tampering. The ALM can facilitate IoT platforms’ storing and tracing of activity logs of IoT DPM in the full lifecycle transparently and trustworthily.
This Recommendation presents a blockchain-based ALM for IoT data processing and management, and specifies its characteristics, functional requirements and architecture.
