Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated age verification systems require users to submit photographs to a back-end service, which may not be feasible without an electronic device and network connection, making them ineffective in situations where such access is unavailable.
Innovation Solution
A computer system equipped with an image capture device and processors that implement automated age estimation, combined with liveness detection, to verify the age of individuals by capturing images and determining if the human characteristics are from a living person, allowing for age-restricted activities without the need for electronic devices or network connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated age verification is performed using back-end services requiring electronic devices and network connections, then verification reliability is improved, but ease of operation deteriorates due to device and connectivity requirements
Solution Approach 1:
The system performs age verification autonomously using an image capture device and processing system that automatically detects human characteristics, estimates age, and determines liveness from captured images without requiring user interaction with electronic devices or network connections
Solution Approach 2:
The patent replaces the mechanical/electronic system requiring smartphones and network connections with an optical system using image capture devices and image processing algorithms to perform age verification through visual analysis of captured images
2Ease of operation
If manual age verification is performed by authorized persons checking physical documents, then ease of operation is maintained, but productivity deteriorates due to time-consuming processes
Solution Approach 1:
The system automatically performs the entire age verification process including image capture, human characteristic detection, age estimation, and liveness determination without requiring manual intervention from authorized persons, thereby significantly improving processing speed and productivity
Solution Approach 2:
The patent replaces the manual visual inspection process with an automated image processing system that uses algorithms to detect human characteristics and estimate age from digital images, eliminating the time-consuming manual document checking process
3Device complexity
If automated age estimation is performed without liveness detection, then device complexity is reduced, but reliability deteriorates due to susceptibility to spoofing attempts
Solution Approach 1:
The system performs liveness detection as a preliminary step before age estimation by analyzing captured images for characteristics indicating a living person is present, thereby preventing spoofing attempts before they can affect the age verification outcome
Solution Approach 2:
The patent introduces liveness detection as an intermediary verification layer between image capture and age estimation, using analysis of human characteristics in captured images to confirm the subject is alive before proceeding with age determination

AI summary
In one or more examples, a computer system is equipped with an image capture device and at least one processor configured to apply automated age estimation to an image(s) captured with the image capture device. In some examples, the computer system is configured to implement multiple age verification methods, such as automated age estimation in combination with one or more other forms of age verification. In some examples, age estimation is supported by liveness detection to mitigate against attempts to spoof the automated age estimation
