Entity Access Control via Trust Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected home devices lack effective mechanisms to manage access based on the activities and trustworthiness of entities entering their operational range, leading to potential security and privacy issues.
Innovation Solution
A system and method that utilize sensors and networking interfaces to identify entities, determine their activities, and assess trust indicators to decide whether to allow or block access to resources, leveraging image, audio, and presence data to trigger alarms or notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connected home devices provide open access to all entities in operational range, then ease of operation is improved, but security and privacy are worsened
Solution Approach 1:
The patent applies local quality by implementing different access control mechanisms for different entities based on their trust indicators. Trusted entities receive full access while untrusted entities are blocked or limited, creating localized security policies rather than uniform access control across all entities.
Solution Approach 2:
The system dynamically adjusts access permissions based on real-time evaluation of entity trust indicators. Access control is not static but adapts continuously as new information about entities becomes available, allowing the system to respond to changing security conditions.
2Reliability
If connected home devices implement strict access control based on entity identification, then security is improved, but device complexity increases
Solution Approach 1:
The patent introduces trust indicators as an intermediary mechanism that simplifies access control decisions. Rather than implementing complex verification of entity identities and intentions, the system uses pre-computed trust indicators that encapsulate security assessments, reducing the complexity of real-time access management.
Solution Approach 2:
The system performs preliminary actions by pre-evaluating entity trust indicators before access requests occur. This advance preparation of security assessments reduces the complexity of real-time decision-making, as the heavy lifting of entity analysis is completed beforehand.
3Measurement precision
If connected home devices monitor and analyze entity activities extensively, then security detection capability is improved, but loss of time and energy increases
Solution Approach 1:
The patent applies partial action by monitoring only the most relevant entity activities and trust indicators necessary for security decisions. Rather than comprehensively analyzing all possible entity behaviors, the system focuses on key indicators that provide sufficient security assurance with minimal processing overhead.
Data Source
AI summary
Concepts and technologies are disclosed herein for managing access based on activities of entities. A computing device can collect data that comprises an image. The computing device can identify an entity that is located in a range of a sensor. The computing device can determine an identity that is associated with the entity and an activity associated with the entity. The computing device can obtain a trust indicator associated with the entity. The computing device can determine, based on the trust indicator, if the activity should be allowed. If the computing device determines that the activity should be allowed, the computing device can initiate allowing of the activity. If the computing device determines that the activity should not be allowed, the computing device can initiate blocking of the activity.
