Anonymized Sensor Data Distribution System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sensor data networks, protecting personal information and ensuring fair compensation for data usage between business operators are challenges, as existing systems often fail to securely anonymize data and accurately calculate usage-based payments.
Innovation Solution
An information processing system that collects data from mobile bodies, converts it to anonymized form, provides access based on data use contracts, and calculates payments based on usage records, using hashing, anonymization, and encryption to ensure secure data sharing and fair compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sensor data including personal information is shared among business operators, then data distribution and utilization are improved, but personal information protection is compromised
Solution Approach 1:
The patent extracts and removes personal information from sensor data before sharing it with business operators. The data management device identifies and separates personal information from the original sensor data, then provides only the anonymized portion to external business operators, thus enabling data distribution while protecting personal information.
Solution Approach 2:
The patent introduces a data management device as an intermediary between data collectors and business operators. This intermediary performs anonymization processing on the sensor data before transmitting it to business operators, acting as a buffer that enables data sharing while ensuring personal information protection through automated anonymization.
2Productivity
If data is provided to multiple business operators, then data utilization value is improved, but payment calculation complexity increases
Solution Approach 1:
The patent implements a system where the data management device automatically calculates payment amounts based on actual data usage records. The system self-services by tracking which business operators use which data, for how long, and in what quantities, then automatically computes the corresponding payment amounts without requiring manual intervention, thus managing payment complexity while enabling multi-operator utilization.
Solution Approach 2:
The patent establishes a feedback mechanism where usage records from business operators are fed back to the data management device, which then uses this feedback to calculate appropriate payment amounts. The system continuously monitors data usage and adjusts payments based on actual consumption patterns, enabling fair compensation across multiple operators.

AI summary
The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.
