Smart Credential Dynamic Display for Privacy and Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issuance of identification badges for temporary or short-term visitors, workers, and contractors in large events or frequent access between facilities poses complexities in data collection, badge generation, and security risks due to potential unauthorized access and delayed retrieval of badges.
Innovation Solution
Smart credentials with dynamic functionality, including context-specific information display, remote programming, and integration with scheduling and access control systems, utilize sensors for gait signature verification and multi-factor authentication to enhance security and manage access efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If identification badges include comprehensive personal information (name, photograph, contact information), then social and professional interactions are facilitated, but security risks increase due to potential unauthorized access and data exposure
Solution Approach 1:
The identification badge incorporates a display device that dynamically changes information based on context. The controller receives context information and adjusts displayed content accordingly, showing comprehensive information only when authorized while limiting exposure during unauthorized periods, thus resolving the contradiction between information versatility and security risk
Solution Approach 2:
The badge system changes the parameter of information visibility based on authorization status. When authorized, the display shows comprehensive personal information; when unauthorized, it shows limited or no information. This parameter change approach allows the badge to adapt to different security requirements without compromising interaction functionality
2Productivity
If identification badges are issued to a large number of temporary visitors and contractors, then access management is enabled, but data collection and badge generation processes become complicated and time-consuming
Solution Approach 1:
The identification badge is designed as a universal device that can serve multiple user types (employees, temporary visitors, contractors) with different access requirements. The same badge hardware and system infrastructure handles all user categories, eliminating the need for separate badge issuance processes and reducing overall system complexity
Solution Approach 2:
The system enables automatic context-based information display without requiring manual configuration for each user. The controller automatically receives context information and adjusts display content, reducing the manual data collection and badge generation workload for administrators while maintaining efficient access management
3Ease of operation
If identification badges display comprehensive user information continuously, then user identity verification is simplified, but personal information protection is compromised
Solution Approach 1:
The display device dynamically adjusts information visibility based on real-time context and authorization status. During authorized periods, comprehensive information is displayed for easy verification; during unauthorized periods, information display is limited or hidden to protect privacy, thus resolving the contradiction between verification ease and information protection
Solution Approach 2:
The controller receives context information as feedback about the current situation and adjusts display content accordingly. This feedback mechanism ensures that comprehensive information is displayed only when appropriate for verification purposes while automatically protecting information when authorization is lacking, balancing ease of operation with reliability
Data Source
AI summary
A smart credential is programmed to show personal information regarding a user on a display when such information is desired or required, and to conceal some or all of the personal information of the user at other times. The information displayed by the credential may pertain to a location of the credential, a level of authorization of the user, or a task or function to be performed by the user. When the credential executes a handshake with a beacon at a secure facility, relevant information regarding the location, the level of authorization, the task or the function is displayed on the credential, and irrelevant information is not displayed. Additionally, a signature of motion by a bearer of a credential may be compared to a signature of motion of an authorized user of the credential in order to determine whether the bearer of the credential is the authorized user.
