Privacy Policy Consent Log Withdrawal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices lack the capability for users to easily withdraw their consent to a privacy policy once it has been consented to, leading to potential unintended use of personal information.
Innovation Solution
A processing device with a storage system to log user consent, a display for managing privacy policy applications, and controllers that govern privacy policy applications based on the presence of consent logs. Users can withdraw consent through a management screen, causing the consent log to be deleted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a consent log is stored to allow application of privacy policy, then the privacy policy can be applied based on user consent, but the user cannot withdraw the consent once given
Solution Approach 1:
The system dynamically changes the state of consent log from stored to deleted based on user's withdrawal instruction. The consent log storage status transitions from a fixed state (consent given) to a flexible state where it can be modified (consent withdrawn) through user action on the management screen, enabling both reliable policy application and adaptable consent management.
2Reliability
If the consent log is permanently stored, then the privacy policy application is reliable, but the user loses control over personal information usage
Solution Approach 1:
The management screen provides feedback to the user about the current consent status and privacy policy application state. When the user issues a withdrawal instruction, the system responds by deleting the consent log, thereby providing continuous feedback loops that enable users to monitor and control their personal information usage permissions effectively.
3Adaptability or versatility
If a management screen is provided for consent withdrawal, then users can control privacy policy application, but the device complexity increases
Solution Approach 1:
The management screen serves multiple functions: displaying consent status, receiving withdrawal instructions, and triggering consent log deletion. By consolidating these functions into a single interface, the system achieves versatile consent management capability while minimizing the increase in device complexity through functional integration rather than adding separate components.

AI summary
A processing device includes: a storage that stores a consent log that allows an application of privacy policy regarding a use of personal information based on an operation by a user; a display that displays an application status of the privacy policy via a management screen; and one or more controllers that control the application of the privacy policy depending on whether or not the consent log is stored. When receiving a withdrawal instruction to refuse the application of the privacy policy via the management screen in a state of allowing the application of the privacy policy, the one or more controllers delete the consent log from the storage.
