KR-20260067552-A - Liquor Cigarette Sales Minor Adult Certification Purpose Identification Confirmation Technology

Abstract

This patent relates to an identification verification device that automatically determines whether a user is a minor when purchasing harmful products such as alcohol and tobacco, and enables compliance with legal requirements through an adult verification process. This system is primarily used in contactless environments such as unmanned stores, vending machines, and self-checkout counters, and is designed to perform adult verification using minimal information by scanning only the year of birth and facial image when a user submits an identification card. This device is designed exclusively for official identification documents such as resident registration cards, driver's licenses, youth cards, and passports, excluding electronic identification documents or unofficial certificates. The scanner automatically extracts information from a predetermined location based on the first two digits of the year of birth and the facial image from the identification document, minimizing unnecessary exposure of personal information and quickly determining whether the user is a minor. Once age verification is complete, the year of birth and facial image on the ID card are encrypted using AES-256 encryption and stored for a certain period (e.g., 3 to 6 months), and can be used as evidence in the event of a legal dispute. After the retention period expires, the data is automatically destroyed. To prevent unauthorized access, a complex password of at least 10 characters and a two-factor authentication process involving identity verification by a police officer or public official are required when accessing the data, and access history is recorded. This system operates in an independent environment isolated from external networks to minimize the risk of data leakage, and protects privacy by displaying only whether the user is a minor on the screen. This ensures compliance with the Personal Information Protection Act and the Child Protection Act, while allowing business owners to securely manage data that can serve as proof of legal liability.

Claims (2)

1. An ID verification device for verifying the age of a minor is characterized by scanning the year of birth and facial image of an ID card to determine whether the person is an adult when purchasing harmful goods such as alcohol or tobacco, and verifying whether the person is a minor using minimal personal information; performing the verification procedure limited to official ID cards provided by the Ministry of the Interior and Safety, such as resident registration cards, driver's licenses, youth ID cards, passports, and electronic ID cards or unofficial ID cards; including an algorithm that extracts only the first two digits of the year of birth at a fixed position based on the facial image in the ID card, and performing adult verification using this information to minimize unnecessary exposure of personal information.
2. The ID verification device according to claim 1, wherein the device stores the year of birth and face image information of the ID card using AES-256 encryption for a certain period (e.g., 3 to 6 months) after adult authentication is completed, and automatically destroys the data after the retention period has expired; controls access rights to the data through a dual authentication procedure requiring a password consisting of a combination of characters, numbers, and special symbols of 10 or more digits and identity authentication by a police officer or public official when accessing the ID card data; reduces the risk of data leakage by operating as an independent system isolated from external networks; manages viewing history by automatically recording data access history; prevents unnecessary exposure of personal information by displaying only whether the user is a minor on the screen; and allows the user to simply check the adult authentication result.

Description

Liquor and Cigarette Sales Minor Adult Certification Purpose Identification Confirmation Technology The technical field of this patent is an automated identity verification system for the protection of minors and adult authentication. It focuses on designing and implementing a system that restricts the purchase of items requiring adult verification (e.g., alcohol, tobacco, etc.) in non-face-to-face and unmanned environments. Unlike existing face-to-face authentication methods, this technology is designed to prevent minors from purchasing harmful items in unmanned stores, vending machines, and self-checkout counters while complying with the Personal Information Protection Act. The primary focus is on performing highly reliable adult authentication using only minimal personal information and securely storing data necessary to prove legal liability in the event of forgery or tampering. This technology has been developed around the following three main elements: the extraction of minimal information to determine whether a user is a minor, encrypted storage and access control for data security, and data retention to prove the business owner's legal liability. The first element, the extraction of minimal information to determine whether a user is a minor, simplifies the authentication process by utilizing only the year of birth and facial image—the core elements of adult verification—while reducing unnecessary exposure of personal information. Existing ID verification methods had limitations in terms of personal information protection as they included sensitive information such as the full resident registration number or address. Accordingly, this system is designed to determine minor status by scanning only the first two digits of the year of birth and the facial image from the ID, while ensuring that other information is not stored or accessible. This enables adult verification by utilizing only necessary information while protecting user privacy, even in non-face-to-face and unmanned environments. The second element is encrypted storage and access control for data security. This technology stores information required for age verification in an encrypted state for a certain period, allowing it to be used as evidence in the event of legal disputes or forgery. To enhance security, store owners must enter a strong password of at least 10 characters, including letters, numbers, and special characters, to access the encrypted data. Furthermore, access requests are granted only upon the request of law enforcement agencies, and a two-factor authentication procedure is implemented to prevent unauthorized access by verifying the identity of police officers or public officials through an identity verification machine. This design ensures compliance with the Personal Information Protection Act while allowing access for legal evidence when necessary. The third element is data storage to prove the business owner's legal liability. In cases where harmful goods are sold to a minor, the business owner must be able to prove that age verification was performed using a forged ID. This technology encrypts and stores birth years and facial images collected during the ID forgery and verification process for a certain period (3 to 6 months), thereby securing evidence that the business owner complied with the Juvenile Protection Act. This data is automatically destroyed after the retention period expires, reducing the risk of excessive personal information storage, and logs are recorded upon access requests to minimize the risk of information leakage. Through this, the business owner can prove their legal responsibility for complying with age verification procedures and utilize the data as reliable evidence in the event of a dispute. In conclusion, the technical field of this patent is an automated identity verification technology designed to protect minors and ensure compliance with personal information protection laws in situations requiring age verification in unmanned and contactless environments. This technology aims to determine whether a person is a minor by utilizing only the minimum information required for age verification and to securely store data to serve as proof of legal liability. Through this, safe and reliable age verification is possible even in unmanned stores and contactless sales environments, simultaneously satisfying two important social demands: the protection of personal information and the protection of minors. The technology underlying this patent is a highly reliable identity verification system for the protection of minors and proof of adulthood. It provides an automated solution that enhances data security and personal information protection, helping business owners prove their legal liability for preventing illegal sales. This system aims to determine whether a user is a minor in situations requiring adult verification in non-face-to-face environments, such as unmanned stores, self-checkout counters, an
