Solution Overview
Problem
In vehicle-based electronic systems, efficiently analyzing data from multiple electronic devices is hindered by the lack of guaranteed anterior-posterior relation of data output, leading to potential alterations and inefficiencies in communication and analysis processes.
Innovation Solution
An information processing device that includes processors to receive and authenticate data, add guarantee information to ensure data integrity, and generate secondary authentication information using the received and guaranteed data, thereby maintaining the anterior-posterior relation and facilitating efficient analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is added to data output from electronic devices, then data integrity can be verified, but the anterior-posterior relation of data cannot be guaranteed leading to analysis inefficiency
Solution Approach 1:
The gateway device performs preliminary actions by adding guarantee information to data before it reaches the analysis device. This guarantee information establishes the anterior-posterior relation in advance, allowing the analysis device to efficiently verify data sequence without complex additional processing, thus resolving the contradiction between reliability verification and analysis efficiency
Solution Approach 2:
The gateway device acts as an intermediary between electronic devices and the analysis device. It adds both authentication information and guarantee information to data, mediating the verification process by establishing data sequence relationships before transmission to the analysis device, thereby enabling efficient analysis while ensuring data integrity and sequence reliability
2Adaptability or versatility
If multiple electronic devices output data at various timings, then comprehensive data collection is achieved, but the anterior-posterior relation between data becomes uncertain causing analysis difficulties
Solution Approach 1:
The gateway device performs preliminary action by adding guarantee information that includes reception timing data before forwarding data to the analysis device. This establishes the anterior-posterior relation in advance, preventing loss of sequence information while maintaining the ability to collect comprehensive data from multiple devices operating at different timings
Solution Approach 2:
The system implements feedback by incorporating reception timing information into the guarantee information. This feedback mechanism allows the analysis device to accurately determine the sequence of data from multiple electronic devices, maintaining data sequence information despite simultaneous or near-simultaneous data output from various devices
