Description

Blockchain-based one-time password registration method and system for preventing unique password exposure at common entrance }

The present invention provides information on the entry and exit of buyers, sellers, deliverers, and joint residence management systems that are parties to online or offline transactions to prevent password exposure at the common entrance of apartments, villas, officetels, etc., where multiple households reside. This is about a one-time password registration method and use system based on blockchain that can manage access to the household common entrance by distributing and storing management information and combining it during delivery.

Since most residents of each household do not change their common entrance password settings frequently and keep them as is, there is always a risk of exposure. If the common entrance password is leaked, it can be used not only for individual households but also for multiple households such as apartments, villas, and officetels. Security should be a concern. Looking at existing technologies to solve these problems,

The visitor monitoring system of Korea Patent Registration No. 10-1187342 is equipped with an operation server that monitors the visitor according to the setting mode of the door phone and wall pad when the license plate number of an entering vehicle is recognized through the license plate recognition unit. However, this is done by installing and equipping a vehicle number recognition device, changing the vehicle number when the deliverer is not a fixed delivery person, notifying the buyer when the delivery person is not confirmed even by monitoring the vehicle number, and confirming actual delivery to the buyer. If this is not done, various security problems may occur. In addition, according to Korean Patent Registration 10-1945688, when an acquaintance or a delivery driver visits, the resident must go through the process of registering the acquaintance's RF card number and delivery invoice number through a household device, which is inconvenient for residents to use. , there are limitations in handling this when delivering large quantities of parcels. Accordingly, the present invention seeks to propose a blockchain-based one-time password registration method and use system that solves the problems of the above prior art and enhances security for access to the common entrance.

The present invention was designed to solve the problems described above.

The problem that the present invention aims to solve is to use a blockchain-based one-time password system to replace household common entrance passwords with blockchain-based one-time passwords and provide them to sellers and deliverers, thereby relieving consumers' anxiety about security and securing access. and strengthening management.

Another problem that the present invention aims to solve is to provide convenience of delivery by reducing the inconvenience that may occur when a delivery company's deliverer enters and exits a common entrance due to incorrect input by the purchaser, while also ensuring the safety of residents of an apartment building.

Another problem that the present invention aims to solve is the installation of additional equipment or the addition of equipment linked to the access management device by the deliverer in order to strengthen the security of access to multi-family residential buildings such as apartments, villas, officetels, etc. By providing this service, we provide economic convenience to apartment building managers, buyers, and deliverers.

In addition, the one-time password used in this system improves security and integrity by combining information distributed and stored on several servers, such as buyer information, deliverer information, deliverer location information, and information from the household residence management system.
