Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring and managing energy and carbon dioxide emissions in facilities lack efficient methods for authenticating and certifying environmental data from sensors, leading to potential inaccuracies and security concerns.
Innovation Solution
An authentication apparatus and method that utilizes sensors to measure and generate statistical information about environmental parameters, which is then authenticated and certified electronically, ensuring the accuracy and integrity of the data through a network of sensors and an authentication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed environment information is transmitted from sensors to authentication apparatus, then data accuracy is improved, but communication load and processing time increase
Solution Approach 1:
The sensor performs preliminary processing by generating statistical information (averages, maximums, minimums) from raw environment data before transmission. This preliminary action reduces the data volume that needs to be transmitted and processed by the authentication apparatus, thereby reducing processing time while maintaining data accuracy through preserved statistical characteristics.
2Loss of energy
If statistical information processing is implemented in sensors, then communication load is reduced, but sensor complexity increases
Solution Approach 1:
The system divides the data processing function into two segments: the sensor segment performs local statistical processing (calculating averages, maximums, minimums) to reduce data volume, while the authentication apparatus segment performs verification and certificate issuance. This segmentation reduces communication load by transmitting only processed statistical information rather than raw data, while distributing complexity across system components rather than concentrating it in one device.
3Reliability
If authentication and electronic certification are implemented, then data reliability is improved, but system complexity increases
Solution Approach 1:
The authentication apparatus acts as an intermediary between the sensor and the data usage system. It verifies the statistical information from sensors and issues electronic certificates that certify the authenticity and integrity of the data. This intermediary approach improves data reliability through formal verification and certification mechanisms, while managing system complexity by centralizing authentication functions in a dedicated component rather than distributing complexity across all system elements.

AI summary
The authentication apparatus includes a communication unit which receives statistical information for a target transmitted from a sensor, the sensor having a measuring unit which measures environment information regarding surrounding environment of the target existing in a space and a statistics generation unit which generates, based on the environment information, the statistical information regarding the surrounding environment of the target, an authentication unit which authenticates, based on the statistical information, that the statistical information is information regarding the surrounding environment of the target, and an issuing unit which, when the statistical information has been authenticated by the authentication unit, issues an electronic certificate certifying that the statistical information authenticated is the statistical information for the target.
