Description

METHOD FOR REAL ESTATE FOR SALE VERIFYING METHOD

The present invention relates to a real estate listing verification method.

Real estate refers to land or buildings. Traditionally, public relations and brokerage for the sale and lease of real estate properties were conducted at off-line brokerage offices. However, in recent years, many real estate properties have been promoted online, that is, through an Internet portal site or a dedicated mobile application. These Internet portal sites or dedicated mobile applications provide real estate listing advertising services. These services promote real estate for sale or brokerage, and impose a predetermined advertising fee on the property owner or intermediary. In such an environment where a real estate sale is advertised and advertised online, a false real estate sale is registered or a photograph of a real estate sale is falsified in order to attract a potential buyer (or a tenant). Such unfair trading practices have reduced the credibility of real estate listings and prevented the growth and expansion of the online real estate services market.

Hereinafter, a real estate property verification method according to an embodiment of the present invention will be described in detail with reference to FIG. 3 to FIG.

3 to 4 are flowcharts schematically illustrating a real estate property verification method according to an embodiment of the present invention.

3 are performed by the user device 200, that is, the client driven by the user device 200, and the steps shown in Fig. 4 are performed by the server 100. Fig.

Referring to FIG. 3, in step S301, the client starts real estate listing.

Subsequently, in step S302, the client receives the address information of the real estate sale from the user. The user can search and input the address information of the real estate sale. From the search result, the user can select an address (street address or road name address) of a real estate sale and further input a detailed address (street, call, etc.).

Subsequently, in step S303, the client obtains the location information of the real estate property corresponding to the address of the real estate property stored in the real estate location database. The real estate location database may be located within the client or server 100. At this time, the client can use the external map service API. In some embodiments, the location information of the real estate for sale includes the location coordinates (GPS coordinates, latitude and longitude) of the real estate property. For example, when the real estate for sale is an apartment, the location information of the real estate for sale includes the coordinates of the central position of the apartment complex. Or, in some embodiments, the location information of the real estate for sale includes boundary coordinates for the occupied area of the real estate for sale.

Then, in step S304, the client acquires the current position information (GPS coordinates, latitude and longitude) of the user device 200. [ Accurate location information can be obtained by obtaining the current location information of the user device 200 before taking a photograph of the second type regarding the real estate for sale, that is, before entering the inside of the real estate for sale. In some embodiments, acquisition of current location information may be performed concurrently with photographing of a first type of photograph regarding a real estate for sale as described below.

Then, in step S305, the client takes a picture of the first type relating to the real estate for sale. The first type of photograph is an outside photograph of the real estate for sale, and the address of the real estate for sale includes a photograph visually identifiable. The first type of photograph is used for verification of a real estate photograph. Verification photos are not exposed to potential buyers, but are used only for real estate listings. For example, when the real estate property is an apartment, the photograph for verification includes photographs related to the display and the room display. The client can take one or more first type photos according to the user's manipulation.

Subsequently, in step S306, the client generates photographing position information and photographing time information of the photograph of the first type as metadata of the photograph of the first type. The client generates photographing position information of the photograph of the first type using the current position information obtained in step S304. As described later, the photographing position information is used for comparison with the position information of the real estate for sale. The photographing time information may be provided in units of time and minutes including the photographing date.

Then, in step S307, the client takes a picture of the second type that is different from the first type regarding the real estate. The photograph of the second type is an inside photograph of the real estate for sale, and includes a photograph that allows the indoor environment of the real estate for sale to be visually confirmed. The second type of photograph is used for service of a real estate photograph. Service photographs are exposed to prospective buyers as real estate listing information. For example, if the real estate property is an apartment, the service photograph may include photographs about a living room, a room, and a kitchen. The client can take one or more first type photos according to the user's manipulation.

Subsequently, in step S308, the photographing time information of the photograph of the second type is generated as the metadata of the photograph of the second type. The photographing time information may be provided in units of time and minutes including the photographing date.

Then, in step S309, the client stores a hash value of the first type of photograph or a hash value of the second type of photograph according to a predetermined hash function in the application database. The photo file and its metadata relating to the real estate property may also be stored in the application database. The hash value of the real estate photograph may also be stored in the application database as metadata of the real estate photograph. Each picture file is determined according to a predetermined file naming policy. In some embodiments, the file naming policy may determine the file name using the real estate registration information received from the user. In some embodiments, the hash value of the real estate photo is generated according to the predetermined hash function with the filename of the real estate photo as a factor. In some embodiments, the hash value of the real estate photograph may be generated by further taking the photographing position information or photographing time information of the real estate photograph described above as a factor. It is also possible that the generation and storage of the hash value are simultaneously performed when generating the photographing position information or the photographing time information in the above-described steps S306 and S308.

Subsequently, in step S310, the client verifies the real estate photograph using the hash value of the real estate photograph of the real estate property registration information to be transmitted to the server 100 before transmitting the real estate property registration information to the server 100. [ The client compares the hash value of the photograph of the first type photograph of the real estate listing information or the hash value of the photograph of the second type photograph with the hash value stored in the application database (i.e., the hash value generated and stored in step S309) , And verifies whether the real estate photograph was forged or altered after the real estate photograph was taken.

Subsequently, in step S311, the client transmits to the server 100 the real estate listing information including the location information of the real estate listing, the photograph of the first type, the photograph of the second type, and the metadata of the photographs. If the client has passed the real estate photo verification in step S310, the client transmits the real estate sale registration information to the server 100, and if the real estate photo verification fails, the client does not transmit the real estate sale registration information to the server 100 . The client can notify the user of the failure of real estate photo verification. The real estate property registration information may further include detailed information such as area, floor, waterproofing, number of bathrooms, direction, porch structure, and heating method.

Referring to FIG. 4, in step S401, the server 100 determines whether or not the real estate listing including the location information of the real estate sale, the photograph of the first type relating to the real estate sale, the photograph of the second type, And receives registration information from the client.

Subsequently, in step S402, the server 100 starts real-estate photo verification of the real estate listing information.

Subsequently, in step S403, the server 100 compares the location information of the real estate sale and the photographing location information of the metadata of the first type photograph to firstly verify the real estate photograph. The server 100 determines the primary verification failure of the real estate photograph if the distance between the location of the real estate property and the photographing location of the photograph of the first type exceeds a predetermined limit distance. The limit distance may be determined differently depending on the type of real estate property. In some embodiments, when the location information of the real estate for sale includes boundary coordinates relating to the occupied area of the real estate for sale, the server 100 determines that the photographing position of the first type of photograph is out of the occupied area of the real estate for sale If so, you can determine the failure of the first verification of real estate photos.

Subsequently, in step S404, the server 100 compares the photographing time information of the metadata of the first type photograph with the photographing time information of the metadata of the second type photograph to second-verify the real estate photograph . When the time difference between the photographing time of the photograph of the first type photograph and the photographing time of the photograph of the second type exceeds the predetermined time limit, the server 100 determines the secondary verification failure of the real estate photograph. This time limit can also be determined differently depending on the type of real estate property. When a plurality of photographs of the first type photograph or the second type photograph are taken, the photographing time of the photograph of the first type photographed last is compared with the photographing time of the photograph of the second type photographed for the first time But is not limited thereto.

Subsequently, in step S405, when the primary verification and the secondary verification of the real estate photograph are passed, the server 100 completes the real estate photo verification of the real estate listing information. In accordance with the result of the real-estate photo verification, the server 100 notifies the user of the verification completion or the verification failure. The verification failure notification may include the reason for the verification failure.

Although not clearly shown, a third verification step of the real estate photograph may be added. In the third verification of the real estate photograph, the address on the photograph determined based on the photograph of the first type is the address information For example, a road name address or a detailed address). The address on the photograph may include a building address display, a display, a room display (not shown) photographed in the photograph of the first type by a character recognition process (for example, OCR And the like. If the comparison between the address on the photo and the address information of the real estate for sale does not match, the server 100 can determine the failure of the third verification of the real estate photograph.

On the other hand, the first verification, the second verification and the third verification do not necessarily have to be performed sequentially. If desired, more than one verification may be performed.

Although not clearly shown, a photo quality verification step may be added to verify whether the photograph is shaken, whether the verification photograph and the service photograph are matched with each other, or the like. In addition, with respect to the privacy issue, a photo correction step may be added to compensate for, for example, mosaic processing of the face or the vehicle number of the person appearing in the real estate photograph.

As shown in [Table 1], the objects of the verification photograph and the service photograph can be predetermined according to the type of the real estate sale. Other objects can be photographed by the user as required by other photographs. As described above, the photographing time limit, which is the basis of the second verification of the real estate photograph, can also be predetermined according to the type of real estate. The user must sequentially photograph the object of the verification photograph and the service photograph. For example, in the case of an apartment, the user should shoot in the order of east entrance -> entrance -> living room -> room -> kitchen. The total photographing time of the real estate photograph may be limited to a predetermined time. The continuity of the photographing can be ensured by the restriction of the photographing time.
