Dynamic Video Access Control for Privacy and Alarm Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video monitoring and alarm systems often compromise user privacy by allowing unauthorized access to video footage during non-emergency situations, which can be a concern for home users.
Innovation Solution
The system allows users to share video and event data with pre-specified third parties only during emergencies, maintaining control over the information shared and ensuring privacy during non-emergency times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the alarm system allows monitoring service access to video footage during emergencies, then alarm verification capability is improved, but user privacy is compromised during non-emergency situations
Solution Approach 1:
The system dynamically adjusts access rights based on the operational state. During non-emergency conditions, the monitoring service has no access to video footage, preserving user privacy. When an alarm condition is detected, the system transitions to emergency mode and grants temporary access rights to the monitoring service, enabling alarm verification. This dynamic state-dependent access control resolves the contradiction by making the harmful factor (privacy compromise) conditional rather than permanent.
Solution Approach 2:
The control panel serves as an intermediary between the user and the monitoring service. It mediates access to video footage by evaluating alarm conditions and controlling whether the monitoring service can access the camera. The control panel presents the user with verification options and controls the disclosure of sensitive information, acting as a gatekeeper that prevents unauthorized access while enabling verified access during emergencies.
2Ease of operation
If the system provides continuous access to video footage to monitoring service, then alarm verification is simplified, but unauthorized access during non-emergencies increases
Solution Approach 1:
The system transitions from a static access model to a dynamic one where access rights change based on the operational state. The control panel continuously monitors alarm conditions and adjusts camera access accordingly. During normal operation, the camera remains inaccessible to the monitoring service, preventing unauthorized access. When an alarm occurs, the system automatically enables verification access, simplifying the verification process while maintaining security during non-emergency periods.
3Reliability
If the user shares video data with third parties during emergencies, then alarm verification is enabled, but information control and privacy protection are reduced
Solution Approach 1:
The control panel acts as an intermediary that controls what information is shared and with whom. During non-emergency conditions, the control panel prevents any information disclosure to third parties, maintaining user privacy and information control. When an alarm condition is detected, the control panel enables selective sharing of video data with authorized third parties (such as monitoring services or emergency contacts) while maintaining control over the sharing process. The user can verify alarm conditions and control which third parties receive information.
Solution Approach 2:
The system performs preliminary verification of alarm conditions before sharing any information with third parties. The control panel first evaluates whether an actual alarm condition exists by reviewing camera footage and sensor data. Only after confirming a legitimate alarm does the system proceed to share information with authorized third parties. This preliminary action prevents unnecessary information disclosure while ensuring that verification is performed before any information loss occurs.
Data Source
AI summary
Video monitoring and alarm verification technology, in which a first connection is established between a first device and a camera located in a monitored property associated with a user of the first device and image data captured by the camera is received over the first connection and at the first device. A determination is made to establish a second connection with a second device that enables sharing of the received image data with the second device and, in response to the determination, the second connection is established between the first device and the second device. The received image data is shared with the second device over the second connection and the second device is restricted from directly accessing image data captured by the camera located in the monitored property.
