Privacy Control System for Biometric Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals lack control over the use of their images and biometric data, which can be captured and shared without their knowledge or consent, leading to privacy and security concerns, especially with the increasing use of facial recognition technology.
Innovation Solution
A privacy control system that allows individuals to indicate their privacy preferences regarding the use of their biometric data, which is stored securely and can be queried to determine authorized uses, ensuring that individuals' identities are not disclosed to parties seeking to use their images or data, with features like image modification to obscure non-consenting individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If facial recognition technology is used to identify individuals in images, then identification accuracy is improved, but privacy and security risks increase due to unauthorized capture and use of biometric data
Solution Approach 1:
The system performs preliminary actions by capturing images and extracting facial biometric data before the individual is identified or recognized. The biometric data is stored in a database along with privacy preference information, enabling future queries to determine whether the individual has authorized use of their image. This preliminary extraction and storage of biometric data allows the system to prevent unauthorized use while maintaining identification accuracy when authorized.
Solution Approach 2:
The system implements feedback mechanisms where individuals can query the system to check whether their image has been captured and stored. The system responds with information about the capture status and privacy preferences, allowing individuals to control and monitor the use of their biometric data. This feedback loop enables individuals to make informed decisions about their privacy while the system maintains the ability to accurately identify individuals when authorized.
2Object-affected harmful factors
If individuals have control over their image data, then privacy protection is improved, but system complexity increases due to query processing and data management requirements
Solution Approach 1:
The system achieves universality by creating a single database that stores multiple types of information including images, extracted biometric data, and privacy preference information. This unified database structure allows the system to handle various functions such as image capture, biometric extraction, privacy preference storage, and query processing all through one integrated system, reducing overall complexity compared to separate systems for each function.
Solution Approach 2:
The system introduces an intermediary layer in the form of a query processing mechanism that mediates between individuals and the stored biometric data. When an individual wants to check their privacy status or authorize use, they interact with the query system rather than directly accessing the database. This intermediary layer simplifies the interface for users while managing the complexity of data retrieval and privacy preference verification behind the scenes.
3Reliability
If biometric data is stored securely, then data protection is improved, but access and query processing become more difficult
Solution Approach 1:
The system segments the stored data into distinct components: images, extracted biometric features, and privacy preference information. Each component is stored separately in the database, allowing for selective access and processing. When queries are made, the system can efficiently retrieve only the necessary segments of data relevant to the individual's privacy preferences and authorization status, making access easier while maintaining secure storage of all data components.

AI summary
Methods and apparatus for allowing an individual to preserve his/her privacy and control the use of the individual's images and/or personal information by other, without disclosing the identity of the individual to others, are described. In various embodiments the individual seeking privacy provides his/her identifying information, images, and sharing preferences indicating desired level of privacy to a control device which is then stored in a customer record. The control device can be queried to determine if an image or other information corresponds to a user who has restricted use of his/her image or other information in a public manner. Upon receiving a query the control device determines using the stored customer record whether an individual has authorized use of his or her image. Based upon the determination a response is sent to the querying device indicating whether the use of the image and/or individual's information is authorized.
