Entry Authentication Control for Tailgating and Companion Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing entry/exit management systems fail to effectively prevent unauthorized individuals from accompanying authorized users by determining the allowable number of companions based on attribute information.
Innovation Solution
An entry/exit management system that performs image authentication, acquires attribute information of authorized users, determines the allowable number of companions based on this information, and permits or denies access for unauthorized users accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image authentication is performed for every user passing through the specific area, then security is improved, but processing time increases and productivity deteriorates
Solution Approach 1:
The authentication process is segmented into two types: full image authentication for the first user and simplified attribute verification for subsequent users. This segmentation allows the system to maintain high security for the primary authentication event while enabling rapid processing for accompanying users, thus resolving the contradiction between security and processing speed.
Solution Approach 2:
The system performs preliminary image authentication and attribute extraction for the first user before they enter the specific area. Attribute information such as registration status and allowed companion count are pre-verified. When accompanying users arrive, the system only needs to verify against pre-stored attributes rather than performing complete authentication, significantly reducing processing time while maintaining security.
2Ease of operation
If the system allows accompanying users without strict authentication, then ease of operation is improved, but security deteriorates due to potential tailgating
Solution Approach 1:
The system provides feedback by displaying information about accompanying users to the first user and seeking their confirmation. The determination unit verifies whether the number of accompanying users exceeds the allowed limit based on pre-stored attributes, and the system responds by either permitting or denying passage. This feedback mechanism ensures security through user verification while maintaining operational convenience through automated decision-making.
Solution Approach 2:
The system enables the first user to self-manage their accompanying users by storing attribute information such as the maximum number of allowed companions. The determination unit automatically compares the actual number of accompanying users against these pre-stored limits and makes permission decisions without requiring manual security intervention, thus maintaining both security and convenience.
3Measurement precision
If attribute information is obtained and processed for each user, then accuracy of companion management is improved, but device complexity increases
Solution Approach 1:
The system uses a universal attribute data structure that stores multiple types of information (registration status, companion limits, user identification) in a standardized format. This universal attribute system can handle various authentication scenarios and user types through the same processing logic, improving accuracy while avoiding the need for separate complex systems for different user categories.
Solution Approach 2:
Instead of creating complex real-time verification systems, the system creates simplified copies of user attributes (such as allowed companion count and registration status) and stores them for quick reference. The determination unit compares actual user counts against these pre-stored attribute copies, achieving accurate companion management through simple data comparison rather than complex real-time analysis.

AI summary
An entry/exit management system includes: an authentication unit that performs image authentication of a user who passes through a specific area; an attribute acquisition unit that obtains attribute information about a first user when there are the first user who has succeeded in the image authentication and a second user who has failed in the image authentication; a determination unit that determines an allowable number of people who can accompany the first user, on the basis of the attribute information; and a permission unit that permits the second user to pass through the specific area together with the first user, when the number of the second users is less than or equal to the allowable number of people.
