Location-Based Service Controller Privacy Data Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based services face challenges in safeguarding user privacy while maintaining the effectiveness of personalized services, as deleting data used for these services results in inefficiencies due to the need for repeated data collection and learning processes.
Innovation Solution
A controller with a memory and transceiver that obtains a mobile device's location and sensor data within a designated area, stores this data, and forwards it to the mobile device when it leaves the area, allowing for secure deletion of the data from the controller's memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sensor data is deleted after providing personalized service, then user privacy is safeguarded, but the system becomes less effective and efficient in providing personalized service on subsequent visits
Solution Approach 1:
The patent segments the data storage function across multiple devices: the controller stores sensor data temporarily during the service period, the mobile device stores personal profile data locally, and the server provides cloud-based data persistence. This segmentation allows each component to handle data appropriately - the controller can delete data after service delivery while the mobile device and server maintain cumulative data for improved personalization on subsequent visits.
Solution Approach 2:
The mobile device acts as an intermediary between the controller and the user's personal data. It stores a local copy of the personal profile and facilitates data synchronization with the server. This intermediary role enables the controller to provide services using sensor data without permanently storing sensitive personal information, while still allowing cumulative learning through server-based data retention.
2Productivity
If sensor data is retained in the controller's memory, then the system can provide effective personalized service, but user privacy is compromised
Solution Approach 1:
The system performs preliminary actions by establishing a personal profile on the mobile device before the actual service delivery. The controller obtains sensor data during the service period, processes it using the pre-established profile, and then deletes the sensor data. This preliminary setup allows effective personalized service without requiring the controller to retain sensitive data long-term.
Solution Approach 2:
The sensor data in the controller's memory functions as a temporary, disposable resource. It is used immediately for service delivery and then discarded through deletion. This approach treats the sensitive sensor data as a short-living object that serves its purpose during the service period and is then safely removed, while the essential personal profile data resides securely on the user's mobile device.
3Object-affected harmful factors
If the system recreates personal profile from scratch on each visit, then user privacy is protected, but the service requires repeated data collection and learning processes
Solution Approach 1:
The system maintains continuity of useful action by keeping the personal profile data on the user's mobile device and synchronizing it with the server. This allows the service to continue improving personalization across multiple visits without requiring complete recreation of the profile each time. The controller can delete sensor data after use, while the essential profile information persists continuously on secure devices.
Solution Approach 2:
The mobile device performs self-service by maintaining a local copy of the personal profile and automatically synchronizing with the server. This eliminates the need for the controller to repeatedly collect and store personal data, as the user's device autonomously manages the profile information. The controller only needs to access data temporarily during service delivery, then delete it, while the profile maintenance continues automatically on the user's device.
