SECURE DOOR ACCESS SYSTEM VIA ENCRYPTED QR CODE AND SMARTPHONES ON DEVICES WITHOUT INTERNET CONNECTION.

Abstract

This invention is an advanced, variable and encrypted QR code access control device designed to provide secure access in residential, commercial, and similar buildings. The system enables secure communication and access via encrypted, time-varying QR codes, eliminating the need for an internet connection. This provides a safe and practical entry method for both occupants and visitors. The device's screen displays variable and encrypted QR codes that direct visitors to a specific website. This website allows visitors to contact the authorized person (the person who authorizes entry in buildings, apartments, workplaces, etc., where entry is controlled for security purposes) they wish to enter. If entry is granted as a result of the video call with the authorized person, the cloud server generates an encrypted entry QR code. This QR code allows the visitor to enter the building with a one-time entry authorization. Authorized individuals can complete the login process using biometric authentication methods on their own phones. This allows the system to provide secure, temporary access for visitors while offering authorized individuals a quick and user-friendly login option.

Description

1 TARIFF ENCRYPTED TRANSACTIONS ON A DEVICE WITHOUT INTERNET CONNECTION SECURE DOOR VIA QR CODE AND SMARTPHONES TRANSITION SYSTEM Technical Area 10 This invention is designed to provide secure access in residential, commercial, and similar buildings. A designed, advanced, variable and encrypted QR code gateway. It is related to the system. The system uses encrypted and time-varying QR codes to access the device. It provides a secure communication and transit process without requiring an internet connection. 15 State of the Art Access control based on different technologies for secure entry and visitor management. Systems have been developed. From traditional doorbells and analog intercoms, to card entry and coded systems. panels, systems that provide remote access via biometric recognition and mobile applications A wide range of solutions are available. With the advancement of technology, this The systems were not limited to simply recognizing visitors and opening doors; they were IP-based. Digital intercoms, remote access, AI-powered security, and biometric authentication. It has gained advanced functionalities such as these. 25 Unlike traditional analog intercoms, IP-based intercoms operate via a local area network (LAN) or the internet. It operates using a connection. These systems, which transmit digital data over IP, include voice and It enables video communication. The doorbell or entry panel displays the image and sound digitally. They operate in this format and transmit information to designated devices over an IP network. These intercoms are typically PoE 30. It works with Power over Ethernet (PEE) technology, which allows it to transmit data over an Ethernet cable. It provides both energy and data transmission. Alternatively, it can operate wirelessly using Wi-Fi. Other models are also available. Users can access them from fixed monitors within the apartment or from mobile devices. By accessing these systems through applications, you can view visitors and listen to their audio. They can communicate and open the door remotely. 35 2 Beyond IP-based systems, there are smart intercom systems. These 5 In addition to the advantages offered by IP technology, these systems utilize AI-powered facial recognition technology. advanced features such as recognition, motion detection, QR code entry, RFID and biometric authentication It has security features. Additionally, it offers cloud-based data storage and remote access. by providing users with the opportunity to manage their doorways more securely. These systems, which can integrate with smart home automation systems, provide security. The cameras can be synchronized with smart locks or alarm systems. Smart doorbell systems available on the market use IP technology to provide homeowners with this service. It allows for remote visitor control. When a visitor rings the doorbell, the integrated system... The camera processes the image and sends it to the user's phone via the mobile application. 15 The user can communicate with the visitor via voice and video through the application, and close the door. It can turn on or receive motion detection notifications. With smart intercom technology, door opening systems can be accessed via mobile applications. They are becoming widespread. However, most of these systems do not have a direct internet connection. This requires that internet access be limited or risky in terms of security. This creates a disadvantage in environments where there is no internet connection. Independent and high-performance, capable of operating offline to provide secure passage in various environments. Safe alternative solutions are needed. Technical Problems That the Invention Aims to Solve Modern access control systems used today utilize IP addresses to provide high security. such as communication based on technology, biometric authentication, and smart device integration. It incorporates advanced technologies. However, these systems also have some fundamental technical problems. 30 It brings with it. Most IP-based systems require a constant internet connection on the device. It is needed. When internet access is interrupted or security vulnerabilities occur. In some cases, these systems may malfunction and users may be unable to log in. 35 In biometric authentication systems, sensitive data such as fingerprints and facial recognition are used. This is usually processed on devices integrated into the door. Biometric data of authorized persons. 3 Storing data on central servers makes these systems vulnerable to cyberattacks. This can lead to unauthorized access or data leakage, potentially affecting users' biometric data. This information could be misused, leading to irreversible security breaches. In addition, advanced camera systems provide high-resolution imaging, artificial intelligence... Because it offers features like intelligence-based authentication, it's quite affordable. The cost is high. Such systems are particularly suitable for commercial buildings or multi-unit apartment buildings. Installation and maintenance costs can reach levels that strain the budget. This invention offers an alternative approach to the technical problems mentioned above, on the device itself. It provides an easy-to-install system that eliminates dependency on the internet for work. 15 This device does not require an internet connection; users can use it on their own phones. It uses an internet connection to process transactions and the system operates in an isolated manner. Communication is ensured securely by being carried out through the user's own mobile device. It provides data communication. Thanks to the flexible structure of the system, it can be integrated into existing security infrastructures. A 20 that is easily integrated and offers high security while also being cost-effective. A solution has been created.
