ITU-T Y.4508 (01/2025)

Functional requirements and architecture of blockchain-based activity log management for Internet of things (IoT) data processing and management

There are many Internet of things (IoT) platforms to process and manage the same IoT data in different stages and in different areas. In traditional solutions, each IoT platform usually stores its activity logs for IoT data processing and management (IoT DPM) within its storage separately. These activity logs are separated and managed by the IoT platforms. Therefore, their accessibility and trustworthiness are not guaranteed, and it is not easy to trace the activities related to IoT DPM in the full lifecycle of the activity logs that are stored and managed by different IoT platforms.
In order to trace IoT DPM activities, 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 the full lifecycle of activity logs for IoT DPM across IoT platforms. Different IoT platforms can individually save activity logs of IoT DPM in 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, across their full lifecycle, from 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 being tampered with. The ALM can facilitate IoT platforms' storing and tracing of activity logs of IoT DPM across their full lifecycle, transparently and in a trustworthy manner.
Recommendation ITU-T Y.4508 presents a blockchain-based ALM for IoT data processing and management and specifies its characteristics, functional requirements and architecture.
