Short Answer Questions

What role do IoT devices play in business operations? IoT devices, such as sensors, controllers, and actuators, play a vital role in business operations by collecting and exchanging data related to assets, processes, and transactions. These devices enable businesses to optimize operations, enhance efficiency, and provide innovative services.

What are the limitations of traditional asset tracking and auditing methods? Traditional asset tracking and auditing methods often rely on independent systems maintained by different enterprises. This fragmentation leads to problems such as lack of transparency, insufficient data verifiability, and difficulty in establishing trust between enterprises.

How does blockchain technology solve the limitations of traditional asset tracking methods? Blockchain technology provides a decentralized, transparent, and secure platform for recording and verifying data. In blockchain, each data block is encrypted and time-stamped and linked to the previous block, creating an unalterable audit trail. This immutability and transparency make blockchain an ideal solution for enhancing the reliability of asset tracking and auditing.

According to the patent, what is the definition of an IoT event? An IoT event is a specific event that is triggered according to predefined rules that are related to sensor data collected by IoT devices. An IoT event is triggered when sensor data meets or exceeds a preset threshold or condition.

Give an example of an application of IoT events in supply chain management. In supply chain management, IoT events can be used to track the temperature, humidity, or location of goods. For example, if refrigerated goods exceed a specified temperature range, an IoT event is triggered to alert the relevant parties to take action.

What is the role of a gateway in an IoT blockchain audit system? The gateway acts as an intermediary between IoT devices and the management service. It is responsible for collecting sensor data from IoT devices, evaluating the data according to IoT event definitions, and generating event data when events are triggered.

How does the management service use the blockchain service to record IoT events? The management service authenticates to the blockchain service using a unique certificate to obtain write access to the blockchain. Once authenticated, the management service can generate encrypted blocks containing IoT event data and add them to the blockchain, creating a secure and auditable record.

How do enterprises benefit from an IoT blockchain audit system? The IoT blockchain audit system benefits enterprises by providing a transparent, secure, and verifiable record of assets. This enhances trust between enterprises, simplifies the audit process, and helps identify and resolve potential issues.

What does the term "sensor data" refer to in this patent? Sensor data refers to various metrics and parameters related to assets collected by IoT devices. This includes temperature, humidity, location, motion, shock, and other data points monitored and reported by IoT devices.

Why is gateway authentication in IoT blockchain audit systems crucial? Gateway authentication is essential to ensure that only authorized devices can contribute data to the blockchain system. It prevents unauthorized access and data manipulation, thereby maintaining the integrity and reliability of blockchain records.
