Sensor-Based Content Access Control for Communication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack the ability for senders to control or revoke content after it has been sent, with limited options for conditional access or removal, and lack secure, sensor-based access control mechanisms.
Innovation Solution
A method that uses sensor data from communication devices to conditionally grant or restrict access to content, allowing senders to control access based on predefined conditions, such as touch patterns or security levels, ensuring secure and controlled content sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is sent through conventional communication channels, then content can be transmitted to the receiver, but the sender loses control over the content after transmission
Solution Approach 1:
The patent implements dynamic access control by continuously monitoring sensor data (geofence location, device state, user activity) to dynamically adjust content accessibility. The system transitions from static send/receive model to dynamic state-based access control, allowing the sender to regain control and modify access rights based on real-time conditions.
Solution Approach 2:
The system establishes a feedback loop where sensor data from the receiver device is continuously monitored and fed back to the sender. Based on this feedback (location changes, device states, usage patterns), the sender can adjust access control decisions, enabling reversible content sharing with ongoing control.
2Reliability
If encryption is used to protect content, then content security is improved, but the sender still cannot control or revoke access after decryption
Solution Approach 1:
The access control mechanism is segmented into multiple independent control dimensions: geofence-based location control, device-state-based control, and usage-pattern-based control. Each dimension can independently enable or restrict access, providing granular control flexibility while maintaining encryption for base security.
Solution Approach 2:
The system changes access parameters dynamically based on sensor data conditions. Access rights are not fixed but adjust according to parameters such as geographic location, device orientation, usage time, and activity patterns, allowing flexible control without compromising encryption security.
3Adaptability or versatility
If remote access is granted to technicians, then support capability is improved, but security risks increase due to unrestricted access
Solution Approach 1:
Before granting remote access, the system performs preliminary verification of sensor conditions (geofence validation, device state assessment, user authentication). Access is only established after these preliminary checks confirm security conditions are met, preventing unauthorized access while enabling legitimate support scenarios.
Solution Approach 2:
The sensor-based access control system acts as an intermediary between the technician and the device. It mediates access rights by continuously evaluating sensor data and making authorized/unauthorized decisions, allowing remote support capability while filtering out security risks through intelligent mediation.
4Reliability
If content access is made conditional based on sensor data, then sender control and security are improved, but system complexity increases
Solution Approach 1:
The access control system leverages existing multi-functional sensor capabilities already present in modern devices (geofence services, device state monitoring, usage pattern tracking). Rather than adding dedicated hardware, the system utilizes universal sensor functions that serve multiple purposes: location-based access control, device-state-based control, and usage-pattern analysis, thereby reducing overall system complexity.
