Vehicle-Mounted Device Member Registration Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted devices lack the capability to perform member registration cancellation for content distribution services, leading to potential retention of personal information from previous users.
Innovation Solution
Incorporating member registration cancellation settings and uplink information transmission mechanisms in vehicle-mounted devices, allowing users to cancel their registration and delete stored content and personal information, which is then verified and processed by the center apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle-mounted device transmits only fundamental information to the center apparatus, then the communication protocol remains simple, but the user cannot perform member registration cancellation or delete personal information
Solution Approach 1:
The system performs preliminary actions by including member registration cancellation information in the uplink information that is transmitted to the center apparatus. This allows the cancellation function to be embedded within the existing communication protocol without requiring separate complex procedures, thus enabling user operation while maintaining protocol simplicity.
2Reliability
If the vehicle-mounted device stores content information and uplink information, then the device can function autonomously, but personal information from previous users may remain in the device
Solution Approach 1:
The system implements feedback by having the center apparatus receive uplink information containing member registration cancellation information from the vehicle-mounted device, verify the cancellation request, and then delete the corresponding member registration information and personal data from its databases. This feedback loop ensures that personal information is properly removed while maintaining the device's autonomous storage capability.
3Adaptability or versatility
If the center apparatus maintains member registration databases, then it can provide personalized content distribution, but it retains personal information from former members
Solution Approach 1:
The system extracts and removes personal information from the center apparatus databases by implementing a cancellation mechanism. When the vehicle-mounted device transmits member registration cancellation information, the center apparatus extracts the member identification, locates the corresponding registration information and personal data in its databases, and deletes them. This allows the system to maintain personalized content distribution capabilities for active members while systematically removing personal information from former members.

AI summary
Provided is an information distribution system (100), in which a control section (4) deletes, when a member registration cancellation of a distribution service is instructed by an input unit (1d) of a vehicle-mounted device (10), the contents information and the uplink information stored in a storage unit (1f), other than the fundamental information, thereby to set ON a member registration cancellation flag. If the member registration cancellation flag is set ON when the communication with a center apparatus (30) is established, moreover, the control section (4) writes a code indicating the member registration cancellation, in the fundamental information of the uplink information, and transmits the same to the center apparatus (30). When this center apparatus (30) receives the uplink information from the vehicle-mounted device (10), the center apparatus (30) decides whether or not the code indicating the member registration cancellation is contained in the fundamental information. If the center apparatus (30) decides that the code is contained, the center apparatus (30) deletes, from a member information DB (341), the member registration information of the record having the vehicle-mounted device ID of the sender vehicle-mounted device (10). As a result, it is possible to cancel the member registration of the distribution service of the content information in the vehicle-mounted device.
