Description

Rental management service provision system using door lock {SYSTEM FOR PROVIDING REAL ESTATE RENTAL MANAGEMENT SERVICE USING DOORLOCK}

The present invention relates to a system for providing a lease management service using a door lock, and provides a system configured to allow access after being notified of a delinquency or a call with a lessor when a chime delinquency occurs.

As the recent stabilization of trading prices has made it difficult to pursue capital gains as in the past, the preference for monthly rent contracts with a guarantee such as reverse tax is increasing rather than cheonsei. As a result, jeonse sales are scarce, while wolse rentals with guarantees have increased significantly, and the monthly rent price remains relatively stable, while the jeonse price is showing a high rise in price. Some say that this market change is the time to change from investment behavior that pursued capital gains in the trading market to investment through operating income in the rental market. The market change to the monthly rent market may cause problems that were not considered in the past jeonse-oriented market, typically related to non-payment of monthly rent or non-payment of monthly rent. Non-payment of monthly rent or arrears is a major risk for lessors, and it is inevitable to consider this in order to pursue stable operating income.

At this time, in order to manage and prevent delinquency of chimes, a lease management method linked to a door lock was researched and developed. In this regard, Korean Patent Registration No. 10-1690010 (announced on December 28, 2016) and Korean Patent Registration No. In No. 10-2035747 (announced on October 23, 2019), a key management application to store and manage encryption key information that can control the opening and closing of the door through communication with the door lock and door lock that controls the opening and closing of the door. The configuration of a server that manages to transmit, update, share, approve, extend, stop, or discard cryptographic key information through interworking between installed user terminals, payment servers for chime payment of buildings, and components, and products If payment is not made on a predetermined date for a place or place, remotely operate the product or a hardware lock provided in the place to stop the operation of the product or set the door of the place to a locked state, and payment is made. In the case of progress, configurations for releasing the stop state of the product or unlocking the door of the place are disclosed, respectively.

However, if the door lock is not unconditionally locked or unlocked, even if the tenant's obligation to pay the rent is in correspondence with the lessor's obligation to make the leaseable object use profit, the tenant's obligation to pay compensation for damages for which the tenant did not profit from use. The lessor loses it separately. Accordingly, there is a need for research and development of a platform that can lead not to unconditionally locking the door lock, but to give the tenant an opportunity to pay or inform the fact of overdue, and to give an opportunity to communicate, such as negotiating with the lessor.

In one embodiment of the present invention, the password set by the tenant is stored and managed in the server, but by linking the account to which the rent is to be paid, such as the lessor's account information, it is possible to determine in real time whether the tenant paid or overdue, or Provides a program that allows the lessor to register the fact that the chime has not been deposited on the server by himself, and in the case of a short-term rental delay, cancel the function of automatically unlocking the door lock with the tenant's terminal and unlock the door only by pressing the access button in the door lock application. However, in order for the access button to be activated, it is possible only after outputting information on the fact of delinquency or after outputting the user interface linked to the payment or transfer method. As a result, the best effect of continuously notifying the fact of delinquency is achieved. In the case of a long-term tenancy delinquency, the access button can be activated only after talking with the landlord, so that the tenant who avoids the landlord's call can be guided to make a call on his own. A method of providing a lease management service using a door lock Can provide. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention registers and uploads a password for opening and closing a door lock, and a tenant terminal and a door lock to open and close the door lock when it is close to or away from the door lock. A management unit that communicates through communication and assigns a unique identification code to the door lock, and when a password is registered from the tenant terminal, a storage unit that maps and stores the password to be linked with the chime payment confirmation information, short-term or long-term preset in the chime payment confirmation information It includes a lease management service providing server including a delinquency prevention unit for driving a door lock and a tenant terminal in a short-term overdue mode or a long-term overdue mode when the chime is not deposited during the period.

According to any one of the above-described problem solving means of the present invention, the password set by the tenant is stored and managed in the server, but whether the tenant paid or overdue by linking the account to which the rent is to be paid, such as the lessor's account information. In real-time, or provide a program that allows the lessor to register the fact that the chime has not been deposited on the server by himself, and in the case of a short-term rental delay, cancel the function of automatically unlocking the door lock with the tenant terminal and enter the door lock application. The lock can be unlocked only by pressing the button.However, in order for the access button to be activated, it is possible only after outputting information on the fact of delinquency or after outputting the user interface linked to the payment or transfer method. The best effect of continuous notification can be obtained, and in the case of a long-term tenancy delinquency, the access button can be activated only after talking with the landlord, so that the tenant who avoids the landlord's phone call can be induced to make a call on their own.

FIG. 2 is a block diagram illustrating a lease management service providing server included in the system of FIG. 1, and FIGS. 3 and 4 are an embodiment in which a rental management service using a door lock according to an embodiment of the present invention is implemented. It is a figure for explaining.

Referring to FIG. 2, the lease management service providing server 300 may include a management unit 310, a storage unit 320, a delinquency prevention unit 330, a button management unit 340, and a call management unit 350. .

The lease management service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with at least one tenant terminal 100, at least one lessor terminal 400, and at least one When transmitting a rental management service application, program, app page, web page, etc. using a door lock to the door lock 500, at least one tenant terminal 100, at least one lessor terminal 400, and at least one door lock ( 500) can install or open a rental management service application, program, app page, web page, etc. using a door lock. In addition, a service program may be driven in at least one tenant terminal 100, at least one lessor terminal 400, and at least one door lock 500 by using a script executed in a web browser. Here, the web browser is a program that enables you to use the Web (WWW: World Wide Web) service, which means a program that receives and displays hypertext described in HTML (Hyper Text Mark-up Language). For example, Netscape , Explorer, Chrome, etc. In addition, the application refers to an application program on the terminal, and includes, for example, an app executed on a mobile terminal (smart phone).

Referring to FIG. 2, the management unit 310 communicates with the door lock 500 through a preset wired or wireless communication, and manages the door lock 500 by assigning a unique identification code. The preset wired/wireless communication between the door lock 500 and the lease management service providing server 300 may include radio frequency-based communication using TVWS (White Spaces) equipment. Here, the radio frequency may be an encrypted communication frequency based on the idle frequency band of the TV. That is, wireless communication such as WIFI, which is commonly used, may not be used. There is a super Wi-Fi that utilizes the TV white space (TVWS), but the basic concept is to use an empty band as a Wi-Fi, rather than using it locally among the TV broadcast frequency bands. Currently, it has excellent characteristics such as 3 times the reach distance, 9 times the transmittance, and 16 times the coverage area compared to the frequency band for Wi-Fi, so it is highly useful in places where it is difficult to establish communication, such as inside a building, as in this embodiment.

As analog TV broadcasting is converted to digital TV broadcasting, some of the existing analog TV frequency bands are not used, so the remaining frequency band and the frequency band that is not used according to a specific region and time are called white space. The FCC (Federal Communications Commission), the US telecommunications broadcasting regulatory body, has decided to open the frequency of the TV white space (TVWS) so that it can be used by unlicensed users. Generally speaking, TVWS ranges from 54MHz to 698MHz, consisting of VHF and UHF. The United States, Korea, and Canada fall into this band, excluding some guard bands. Europe corresponds to 470 MHz to 790 MHz. In the case of Korea as well, since 2013, when analog TV broadcasting was terminated and digital broadcasting conversion was completed, TV idle bands can be used, and commercial services are available from 14 years, so by using these bands by setting encryption, idle resources are also utilized and secured by encryption. You can also do it thoroughly.

When a password is registered from the tenant terminal 100, the storage unit 320 may map and store the password so as to be linked with the rent payment confirmation information. In this case, the password may include at least one or a combination of at least one of text data, image data, and biometric data. At this time, since passwords, accounts, and phone numbers are information to be protected according to the Personal Information Protection Act, at least one type of encryption technique can be applied. Assuming that each lessor or tenant is configured as a private blockchain as each node, the RSA (RIVEST-Shamir-Adleman) key can be assigned to at least one terminal corresponding to at least one node constituting the blockchain. have.

In this case, RSA is a two-way asymmetric key encryption algorithm, that is, a public key encryption algorithm based on the difficulty of prime factorization for multiplying a large prime number. RSA uses two keys, a constant that converts a message or ciphertext. In general, the public key of many public key algorithms is known to everyone and is used to encrypt messages, and encrypted messages can be decrypted and opened only by a person with a private key. . However, the RSA public key algorithm does not have these constraints. It can also be encrypted with a private key and decrypted with a public key. In this case, the RSA encryption process may include key generation as a first step, key distribution as a second step, encryption as a third step, and decryption as a fourth step.

First of all, for key generation, randomly different prime numbers, p and q, are selected. For security purposes, p and q must be very large numbers. This can be calculated through a computer operation with an algorithm for determining whether there is a prime number such as the Rabin-Miller algorithm, and n, e, and d are obtained through an operation such as Equation 1 below.

At this time, e is a value that satisfies 1<e<φ(n) and gcd(e,φ(n))=1, and d is a value that satisfies ed=1 (modφ(n)). In this process, an extended Euclidean algorithm may be used. At this time, (n,e) is the public key, (n,d) is the private key, and when the message is converted to a natural number m less than n, the RSA public key encryption process is as shown in Equation 2 below, and RSA public key decryption The process is shown in Equation 3.

The proposition that such conversion is established can be proved by Fermat's prescribed principle, and public key conversion, that is, encryption, and decryption, which is a conversion of a private key, is an inverse function relationship. That is, Pu()=Pr ^-1 () holds. The public key algorithm differs from the symmetric key algorithm in that anyone can encrypt a message, but there is only one person with a private key who can decrypt it and read it.

The asymmetric key encryption algorithm differs in that it requires a different key, that is, a constant for encrypting and decrypting a character string when encrypting and decrypting. Among these encryption algorithms having such characteristics, in one embodiment of the present invention, for example, RSA-2048, which is an RSA cipher for a composite number N of 2048 bits, can be used, and the SHA-256 (Secured Hash Algorithm) one-way encryption algorithm and You can also sign electronically together.

Meanwhile, SHA (Secured Hash Algorithm) is a set of cryptographic hash functions designed by the US National Security Agency (NSA). This is characterized in that it is not possible to find out the existing encrypted string, and the encrypted string is a one-to-one correspondence to the encrypted string. With this characteristic, the current data, which should be the original text, is encrypted and compared with the encrypted contents of the existing text, so that a person can grasp the integrity of the data.

Alternatively, proxy re-encryption can be used, which is a kind of public key encryption technique that allows a proxy entity to convert ciphertext from one public key to another without knowing anything about the underlying message. Compared with the existing PKE (Public Key Encryption) protocol, which is ideal for 1:1 communication, it has good scalability for N:N communication between any number of data producers and consumers. When external users request users to view the encrypted data stored in the blockchain, the user confirms and issues a proxy re-encryption key through the cloud server so that data can be safely transmitted to external users without decrypting the data. I did. Atomic proxy cryptography (BBS98) method can be used to generate the proxy key, which converts A's ciphertext into B's ciphertext, which is simple and has good performance based on the ElGamal encryption-based algorithm. In addition, various encryption methods such as AES (Advanced Encryption Standard) can be used, and are not limited to the above-described methods.

The overdue prevention unit 330 may drive the door lock 500 and the tenant terminal 100 in a short-term overdue mode or a long-term overdue mode when the chime is not deposited for a short or long-term preset in the chime payment confirmation information. At this time, in the short-term delinquency mode, if the deposit of the chime is not confirmed for a preset short term, the door lock 500 cancels the function of automatic lock release so that the automatic lock release is not performed even if the door lock 500 recognizes the tenant terminal 100, and the tenant terminal In (100), the function of automatic unlocking is activated only when the installed access application is activated and the access button is selected, and the delinquency notice data is transmitted to and outputted to the tenant's terminal (100), and then delinquency is received by at least one transfer means. It may be a mode of controlling to transfer.

In the long-term delinquency mode, if the deposit of the chime is not confirmed for a preset short period, even if the door lock 500 recognizes the tenant terminal 100, the function of the automatic lock release is canceled so that the automatic lock release is not performed, and the tenant terminal 100 ) Is set to activate a pre-installed access application and make a call to the lessor terminal 400 before selecting the access button, and only when a call is made from the lessee terminal 100 to the lessor terminal 400 It may be a mode in which the access button is set to be activated. In this case, only when the access button is selected, the function of automatically unlocking the door lock may be activated.

In summary, in the short-term overdue mode, you must confirm the fact of the overdue to be able to enter, and in the long-term overdue mode, the tenant will first call the landlord to determine when to pay the overdue rent, focusing on the tenant avoiding the landlord's phone call. Although you have to answer, the main point is to allow you to enter the rental object. This is because most landlords who are overdue for a long period of time usually call the tenant before sending the maximum statement to the tenant as proof of contents, and most of them want to receive a definite answer on how to repay the rent. Of course, there are some tenants who do not pay if the deposit covers the delinquency of the rent during the contract period, but if the loan delinquency period is long and the contract expiration is far, the lessor suffers damage corresponding to the statutory interest. Paying and receiving chimes is also important to risk management.

If the lessee is unable to make a difference due to the recent deterioration of the situation, it may be induced to apply for a housing support program established in accordance with the purpose of the constitution and guaranteed housing rights. Recently, there are increasing cases of suicide due to life hardships, but there may be cases in the blind spot of welfare or not even knowing that there is such a system, so if there is consent to the use of personal information from the tenant's terminal 100, there is a difference between salary or income and expenditure in advance. By calculating the difference, you can also check whether it is eligible for application.

There are various opinions on the definition and components of housing cost burden capacity or Affordability, and accordingly, there are various methods of measuring burden capacity. Until now, researchers have suggested various methods of judging the ability to bear housing expenses mainly based on the relationship between income and housing expenses. Among them, the proportional approach and the residual income approach are representative. The Ratio Approach judges capacity to bear based on a normative basis between income and housing expenses. This method is based on the perception that the share of housing expenses in income is the result of the household choosing one of the limited and unsatisfactory alternatives. Therefore, if a certain percentage of income is set as a normative boundary and the household pays for housing in excess of that percentage, it is believed that non-housing necessities will not be sufficiently consumed. The price-to-income ratio (PIR) and rent-to-income ratio (RIR) are representative methods of the ratio approach.

Among them, when calculated by the method used in the residential welfare program provided by the local government or the central government of the tenant's terminal 400, there is a program that can apply for the income, expenditure, and rent of the tenant terminal 400 as input values. It may help to receive support by searching whether it is there, and sending it to the lessee terminal 400 if it exists. The housing subsidy program is a housing welfare policy for the low-income class, and can be divided into a subsidy method for a supplier (producer) and a subsidy method for a consumer (consumer). The latter, the consumer subsidy method, is to directly pay a certain amount of subsidies to low-income people with little or no ability to pay rent, and housing vouchers and housing allowances are typical programs. In general, consumer assistance methods such as housing vouchers and housing allowances can reduce the beneficiary's rent burden.

Among the housing subsidy programs, the housing voucher is a program that provides partial support for rent in consideration of household income. Housing vouchers provide support for beneficiaries' limited purchasing power to ease budget constraints so that they can consume housing-related goods and services. On the other hand, housing allowance is a subsidy paid by the government to compensate for the difference between housing costs, such as rent and loan repayment, and costs that low-income people can reasonably bear.

Living wage standard amount)'Standard (real) rent' can be provided in full, or (recognized income> living benefit standard amount)'standard (real) rent-self-pay', self-pay = K (self-pay rate 0.5) Calculated by the same formula as ×Y (recognized income-standard amount of living benefit) This is an example, and is not limited to the above formula since each formula may be changed continuously according to a policy change or change. If each condition is met, a request for an application to the tenant terminal 400 or a service for proxying the application may be provided.

When the tenant terminal 100 is driven in the long-term overdue mode, the button management unit 340 activates the access button when the tenant terminal 100 attempts to connect a call to the lessor terminal 400 but does not make a call. A call attempt event may be transmitted to the terminal 400. At this time, the number of call connection attempts may be singular or plural. As an example of the setting function according to the chime delinquency, it is possible to present variously such as automatic pass, manual pass, one-time key issuance, and access stop. For example, in the case of non-payment of short-term and long-term chimes, it is a rule to pass through passively, but in special cases, the landlord may issue a one-time key or suspend access if the court does not comply with an eviction order. For convenience, such a management program can be classified into a program for renters and programs for renters.

The call management unit 350 may map and store the lessee terminal 100, the lessor terminal 400, and the available call time when the lessor terminal 400 sets the available call time. This is because if the tenant returns home at 1 am and calls the landlord because the access button is not pressed, the landlord cannot lead a proper life.

In addition, the lease management service providing server 300 is predicted that unpaid management fees and overdue rents will exceed the deposit, and even if a payment order is issued under the Civil Procedure Act, in consideration of the judicial process required period of at least 3 months, each case After collecting the data, it can be converted into big data to notify the risk and provide guidance on legal measures such as requesting a forced eviction order to the lessor. To this end, the lease management service providing server 300 collects a data set for various cases, such as when the rent is overdue and then goes to forced eviction, or when the tenant is overdue and then flees at night, that is, a data set on the case of receiving a damage report from the lessor. After pre-processing, labeling and setting with training data, artificial intelligence modeling can be performed.

At this time, the lease management service providing server 300 refines unstructured data, structured data, and semi-structured data included in the stored raw data, and performs pre-processing including classification as metadata. It is possible to do, and big data can be built by performing an analysis including data mining on the pre-processed data. Data mining is classification, which predicts a class of new data by learning a training data set with a known class by searching for an intrinsic relationship between preprocessed data, or clustering, which groups data based on similarity without class information. It may include performing. The lease management service providing server 300 may model an artificial intelligence algorithm after learning and testing big data. However, in an embodiment of the present invention, since various types of artificial intelligence algorithms can be used, it is not limited to any one algorithm, and it will be apparent that various artificial intelligence algorithms can be used according to embodiments.

When operating the embodiment of the present invention after constructing with the initial big data, behavior data of the tenant may be additionally collected, and relearning may be performed through this. For example, an unpaid bill was floated on the screen, but it was immediately turned off, or you had to call the landlord, but pretending to make a call, for example, after the signal went only once or twice, the call connection signal was generated. It collects behavioral data such as cheating the system as if there was no currency, and information about whether or not these tenants eventually paid arrears, and if not, what they did during the eviction process or at the time of contract expiration. If you can continue to accumulate and collect, and if additional learning is conducted on this, it is possible to predict the direction in which the new tenant will be delinquent when the new tenant starts overdue, and by notifying the landlord in advance to make the best in advance. In addition, after limiting the unpaid maintenance fee and cleaning fee from the deposit, there is nothing left to prevent overdue rent and the worst case in which it is impossible to offset.

Artificial intelligence is a technology that makes machines think and act like humans, and is classified into machine learning, deep learning, and reinforcement learning according to the way they impart intelligence. . Among these, machine learning and deep learning techniques are mainly used in the field of emotion recognition. First, machine learning means that a machine learns data directly, finds a set of hidden regularities, and evaluates and predicts new data based on it. A classification model may be used for various machine learning algorithms such as SVM (Support Vector Machine, hereinafter SVM) and KNN (K-Nearest Neighbor, hereinafter KNN), or a classification model subdivided using machine learning may be used.

However, these machine learning-based methods classify the characteristics of the tenant based on the artificially selected characteristics, and the limitations of the algorithm performance itself, which is difficult to apply a large amount of data, can also be pointed out as a problem. You can also use deep learning. Deep learning is a result of the development of an artificial neural network, an algorithm in the field of pattern recognition, and deep learning for a tenant classification model may be used to classify the results of the tenant's behavior. To this end, a model with better performance may be used by comparing the representative machine learning algorithms, Naive Bayes (NB) and SVM, and the deep learning algorithm, Deep Neural Network (DNN).

Hereinafter, the operation process according to the configuration of the lease management service providing server of FIG. 2 will be described in detail with reference to FIGS. 3 and 4 as examples. However, it will be apparent that the embodiment is only any one of various embodiments of the present invention, and is not limited thereto.

Referring to FIG. 3, (a) the lease management service providing server 300 stores a password when a password is input from the tenant terminal 100, but maps the tenant information, landlord information, and password to the door lock to store the password. And, (b) in the case of arrears or non-payment of management fees, the lease management service providing server 300 cancels the automatic unlocking function of the door lock 500, and then (c) runs the access application for access. And, after outputting information on unpaid bills or overdue chimes, that is, after allowing the tenant to check them, the access button can be activated so that the door becomes the best every time the door is opened or closed.

Thereafter, the access button can be activated only after the tenant checks all of them as shown in Fig. 4(a). In order to prevent the abuse of activating only the access button without seeing it properly, the rental management service providing server 300 scrolls to the end. Alternatively, you can control activation after checking if flipping has occurred. At this time, in the case of conversion to long-term delinquency as shown in (b), the automatic lock release function is canceled (maintains the canceled state), and each time the door is opened or closed (c) the door can be opened and closed only after calling the landlord. By activating the button, an office worker who goes to work can call the landlord at least twice a day to pay off the unpaid rent and maintenance fees.
