Description

Mobile variable security QR code-based access/attendance management system {MOBILE VARIABLE SECURITY QR CODE-BASED IN-OUT AND ATTENDANCE MANAGEMENT SYSTEM}

The present invention is an integrated implementation of access management, attendance management, quarantine management, and simple contracts. Specifically, through complex authentication using FIDO (fast identity online) and OTAC (one time authentication code) authentication as simple authentication It relates to a system that integrates an access management and attendance management system and a simple contract system.

In the era of Corona, due to non-face-to-face, mobile, and telecommuting, the conventional access control system and time and attendance management system are used in a way that passes through an offline gate using a separate access card or recognizes it on a physical terminal.

In this access card method, workers at the site can steal another person's access card, a separate recognition terminal must be installed, and it is not suitable for a work environment such as telecommuting.

Therefore, there is a need for a means that can smoothly perform procedures such as authentication as well as access and attendance management between all workers or between employees and employees in a non-face-to-face manner.

In connection with these access management and attendance management, the conventional access and attendance management system mainly uses a separate dedicated card or fingerprint, which has a high risk of card loss or theft, and the hassle of fingerprint registration and management burden. Problems may arise, and difficulties in quarantine may arise due to contact with fingerprints.

On the other hand, the conventional contract management system is made of paper documents on the offline.

Such paper documents have problems in that it is difficult to easily check the authenticity of the contract or the possibility of forgery, and it is cumbersome to write the contract individually and it is not easy to store and manage even in the case of frequently occurring employment contracts for freelancers or temporary workers.

Accordingly, there is a need for a non-face-to-face means that can smoothly perform procedures such as verification of contracts between employers and employees as well as authentication.

In connection with such an employment contract, the conventional access and attendance management system mainly uses a separate exclusive card or fingerprint, but this has a high risk of card loss or theft, and the hassle of fingerprint registration and management burden. may occur, and difficulties in quarantine may arise due to contact with fingerprints.

Even in the current era of transition to a non-face-to-face society, there is an urgent need for a means to solve issues such as the convenience of signing contracts as well as storage, certification, and security of contracts.

In addition, by being configured to link and manage quarantine management by complex authentication, there is an effect of automating access/attendance/quarantine management and enhancing convenience.

On the other hand, various contracts such as employment contracts, insurance contracts, purchase contracts, and real estate contracts are photographed, and the parties to the contract are authenticated and uploaded to the server through messenger and complex authentication, and are configured so that they can be used. There is an effect of realizing contact and securing security such as prevention of forgery and alteration.

In particular, from the standpoint of the company or the standard of one worker, by integrating and implementing multiple application fields into one data proof container service based on simple complex authentication without installing various applications, the quality and convenience of service It has the effect of increasing efficiency.

More specifically, it is configured so that various contracts such as employment contracts, insurance contracts, purchase contracts, and real estate contracts can be photographed, authenticated and uploaded to the server through QR authentication generated by messenger and composite authentication between the contracting parties, and used. , it has the effect of realizing the convenience and non-face-to-face contact of contract conclusion, and securing security such as prevention of forgery and alteration.

At this time, the QR used for this system is not a general fixed-value QR, but a QR with validity over time, and it emerges as a QR that includes information generated from a one-way dynamic random code such as OTAC as well as biometric information FIDO simple authentication and will be used in this system.

In particular, when contracts are changed, contract changes or additional contracts are additionally created through voice recording, and are configured to be managed in a server or blockchain ledger through mutual authentication by QR generated by complex authentication, making it convenient even in non-face-to-face. It has the effect of completing contracts safely and safely performing certification work. That is, there is an effect of maximizing convenience and efficiency by implementing new service models such as taking and signing, talking and signing.

In addition, it is configured to link and manage access management, time and attendance management, and quarantine management of the contracting parties based on the contract by QR authentication generated by complex authentication, which has the effect of automating access / attendance / quarantine management and enhancing convenience.
