BG3945U1 - Remote access control system - Google Patents

Abstract

This utility model relates to a system for remote access control of movable and/or immovable property, which can be leased for a short period of time as: hotel rooms, guest houses, bungalows, buildings, offices, campers, caravans and others through an electronic smart lock or cartridge lock, hereinafter referred to as "locking device", and a set of software support systems for administration. On a computer, server or other software system is performed the user's access control in a pre-set period. Via a device is configured the loading of codes and/or program keys in the locking devices. The user receives an access code, RFID card or way of use through a mobile application, through which it can be used the locking device for the reservation period. Through this system, the user has access to a list of vacant properties for short-term rent and can request access for a certain period. It is required manual or rule-based approval from an administrator or owner. The application automatically transmits and administers the information or data required to access when they connects to the locking device, when the user is directly in front of the locking device. The communication is carried out via Bluetooth LE. RACS provides automatic access control in cases of unplanned need by generating an end number of unique codes, valid in a certain time interval, which are refreshed and loaded periodically in the locking devices. The locking devices used in this utility model are independent of a permanent power source and internet connection and are able to store information for carrying out the access control. When occurs a change in the access control schedule, the data in the locking device is updated each time it interacts with a mobile device transferring the corresponding update via RACS. Due to the pre-set schedule or set rules at any time it is clear which mobile devices have access, which locking devices they have access to and automatically when there is an Internet connection they receive the latest update for the locking devices to which they can have access. Due to the previous statement, the possibility for mobile devices to have unauthorized access is also eliminated.

Description

BACKGROUND OF THE INVENTION

Various systems for remote control of access to real estate are known (Figure 1) through a combination of locking devices and accompanying administration systems. A disadvantage of known remote real estate access control systems is that they require an authorized administrator who is trained to work with all systems, configure access cards or manually load codes into locking devices. These codes and cards are then distributed personally to users. Systems and even locking devices need a local LAN or WiFi network, an Internet connection and a constant power source to function properly. The user unlocks the locking device with a preset code or a pre-configured and issued RFID access card. These cards must be returned after the expiration date and the codes must be disabled manually or automatically based on rules.

The disadvantage of these systems is that it relies on an Internet connection or a local connection to other systems and networks that transmit data. These solutions require manual administration and configuration to provide the necessary data to each of the locking devices. They are also energy dependent. Another disadvantage is that they are difficult to handle and require additional work around organizing access for users. This makes them inapplicable in areas without or with limited internet coverage or vacant homes, campers, caravans, bungalows and others, where electricity supply may be conditional. In cases where there is no possibility for permanent presence of an authorized and trained administrator, such systems cannot be used.

Technical essence of the utility model

The task of the utility model is to propose a system (Figure 2) that is energy independent and eliminates the need for manual administration, while providing the same or better functionality. It is solved by achieving autonomy and independence from the need to create access from a future user to the connection of the software product with the peripheral locking devices. For this purpose, the user installs a mobile application, hereinafter referred to as "DODI" in his smartphone, identified by

BG 3945 UI your phone number and unique activation code. Through DODI, he has access to a list of vacant properties for short-term rentals and can request access for a certain period. Manual or rule-based approval from an administrator or owner is required. The application automatically transmits and administers the information or data necessary for access when connecting them to the locking device, when the user is directly in front of him. The communication is via Bluetooth LE. DODI provides automatic access control in case of unplanned need by generating a finite number of unique codes, valid in a certain time interval, which are refreshed and loaded periodically in the locking devices. The locking devices used in this utility model are independent of a constant power source and internet connection and are able to store access control information. When there is a change in the schedule of access control, the data in the locking device is updated at each subsequent interaction with a mobile device transmitting the corresponding update via DODI. Due to the pre-set schedule or set rules, it is clear at any time which mobile devices have access to which locking devices and automatically when there is an internet connection they receive the latest update for the locking devices they can access. Due to the previous statement, the possibility for mobile devices to have unauthorized access is also eliminated.

Examples of implementation of the utility model

The solution of the current utility model includes three elements: DODI cloud service; ADD mobile applications; locking device.

With these components, the utility solves the technical challenges and achieves flexibility, autonomy and comprehensiveness in the short-term rental of movable or immovable property as described in the scope of the current utility model.

Locking device

The utility model does not provide a specific locking device, but supports a set of common ones. This makes it independent, ie flexible in terms of types of locking devices, but the following requirements must be met.

The locking device must be energy independent, powered by solar energy and / or a battery or other external source of electricity.

• The locking device must provide service access in the event of a mains failure, assuming a charging method or connection to an auxiliary power supply.

BG 3945 UI • The locking device must provide the possibility for secure data transfer with a smartphone via Bluetooth LE protocol with a minimum version of the specification 4.1.

• The locking device must support a way to cryptographically sign messages and store data in encrypted form, as well as work with cryptographic algorithms such as AES 128, AES 256.

• Locking devices based on Nordic semi. nRF52 and Nordic semi. nRF53 chips are recommended.

• The locking device must provide functionality for storing numerous keys valid for a given period, validate them and restrict them after the period.

• The locking device must be able to report on request who, when and how has accessed the device via Bluetooth communication.

• Optionally may support RFID and / or NFC chips and cards.

• The locking device must have a minimum autonomous life of 6 months with an average of 10 communications or interactions per day.

ADD mobile applications

Android and iOS-based DODI applications provide a convenient and easy reservation management interface described in the utility model area. Management is performed only through authorized persons and supports various roles. Roles can be "owner", "user", "administrator" and service role. Communication with the locking device is carried out via Bluetooth LE 4.1+ in encrypted form according to a predefined protocol known to both parties. The use of communication via NFC is also allowed, as the locking device can work both in active receiver mode, emitting a magnetic field, and to emulate a passive transmitter (card emulation). Users register in mobile applications via phone number and OTP (One Time Password) - a password valid for 30 s, similar to bank tokens; email address and password or through a link to a social profile (Google, Facebook, Apple, Microsoft) after verification.

Locking devices are initialized once in the presence of their owner through the mobile application in which they have pre-registered. The administrator can manage and provide third parties with access through DODI. DODI mobile applications are data packet carriers. They are a digital key that securely provides access configuration and reservation information to locking devices for which the user has previously granted access or administrative rights. Automatic synchronization is performed in the presence of mobile data or internet connection, ensuring that the most current and necessary data is stored in a secure form on the phone. Thus, in the absence of connectivity, the smartphone can still be used as a digital key. In addition to the current reservation, the smartphone also charges the future confirmed ones in the lock, which means that it is possible, but not necessary, not to have a phone when unlocked in the next reservation. The user must enter a lock code that he has understood in advance.

ADD cloud service

It manages the access, roles, reporting and synchronization of the digital data packets (keys) of the respective locking devices to the users who have explicit access to use.

DODI mobile devices actively communicate with the cloud service via HTTPS security protocol and service-specific way of authorization through the so-called. API Keys and Secrets. Sometimes a constant connection is required for synchronization of critical data in real time, which is done through the so-called. WebSockets technology.

EVEN the cloud service is available everywhere. It is not restricted within an internal network, but anyone wishing to use it must be authorized by an account and / or by the provided communication software interface, protected by the aforementioned API keys and secrets, which are issued through registration and / or manually by an administrator.
