Electronic Access Pass with Temporary Display for Secure Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic access passes compromise security by revealing sensitive information, and the absence of printed information hinders authentication within restricted-access areas, leading to potential unauthorized access.
Innovation Solution
An electronic access pass with a secure element that authenticates the pass reader, temporarily displays relevant information upon successful authentication, and disables the display upon exiting the restricted-access area, ensuring confidentiality and authenticity while allowing visual verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is printed on the access pass for visual inspection, then authentication within the restricted-access area is improved, but information confidentiality is compromised as third parties can read sensitive data
Solution Approach 1:
The display means are activated in advance before the pass carrier enters the restricted-access area and remain active only during the duration of access. This preliminary activation ensures information is available for authentication when needed, while automatically disabling afterward prevents unauthorized reading by third parties outside the area.
Solution Approach 2:
The display means transition from an inactive state to an active state upon authentication and return to inactive state upon exiting the restricted-access area. This dynamic control of information display resolves the contradiction by making information visible only when and where it is needed for authentication, rather than permanently visible or completely hidden.
2Loss of information
If no information is printed on the access pass to maintain confidentiality, then information security is improved, but visual authentication by security personnel and peers is hindered
Solution Approach 1:
The system prepares the display means for activation before the pass carrier enters the restricted-access area. This preliminary preparation ensures that when authentication is needed, the information is already ready to be displayed, eliminating the need for permanent printing while enabling on-demand visual verification.
Solution Approach 2:
The display means act as an intermediary between the stored information and the authentication process. Instead of directly printing information on the pass or requiring complex verification procedures, the display means provide visual information on demand, facilitating easy authentication without compromising confidentiality.
3Loss of information
If information is stored in memory rather than printed on the pass, then information confidentiality is improved, but immediate visual verification requires additional equipment and time
Solution Approach 1:
The pass itself provides the visual authentication information through its integrated display means, eliminating the need for external pass readers or screens. The pass carrier can immediately verify their own credentials by viewing the display, and security personnel can quickly authenticate without additional equipment, significantly reducing authentication time while maintaining confidentiality.
Solution Approach 2:
The display means serve multiple functions: they provide visual authentication information for security personnel, allow self-verification by the pass carrier, and dynamically control information visibility based on location. This multi-functionality eliminates the need for separate verification systems and equipment.

AI summary
The invention relates to an electronic access pass allowing a person associated with the pass to access at least one restricted-access area of a building, and to a method implemented by such a pass for accessing a restricted-access area of a building. According to some embodiments, when a pass reader authorizes access to said area after reading the pass, information selected on the basis of the restricted-access area is temporarily displayed on the pass. This makes it possible to identify the carrier within the area based on the information displayed on the pass, while at the same time limiting the possibility of information being recovered through a simple glance outside the area. Overall security is thereby improved as a result, both within the area and outside it, due to the temporary nature of the display.
