In this embodiment, when a real estate registration entry request sent by a real estate registration system is received, the content requested to be entered is stored in two servers at the same time, and the stored data in the shared server is managed by setting an entry timestamp. The invention considers the aging characteristic of real estate, and when a certain user needs to share and inquire a certain fixed estate, all the businesses of the user are usually completed in a time region, such as three months or half a year. For example, when a user purchases a real estate, the corresponding real estate procedures such as registration, passing home, etc. are completed in a short time, and for example, real estate transaction is completed, there is no exact time limit in the negotiation time before the transaction, but the time interval for completing the negotiation and completing the transaction is fixed and regular. And many real estate can not be subjected to shared query operation for a long time (taking years as units), and if all real estate registration information is traversed in each query, the total amount of query data can be increased. In the prior art, the time characteristic of real estate during business processing is not considered, so that the time stamp management cannot be carried out on the existing real estate registration information, and the technical means of separately storing the time stamp and the data cannot be adopted to improve the speed of data query.
In this embodiment, the sharing server manages the internal storage data according to the entry timestamp, specifically: the sharing server judges whether to delete the internal storage data or not according to the internal storage capacity and the load balance of the sharing server within a preset time period; if yes, the shared placement server sorts the real estate registration information from first to last according to the entry time stamp of the real estate registration information, and deletes the first N pieces of real estate registration information; wherein N is a preset positive integer; if not, the operation is ended. The invention judges whether to delete data according to the conditions of storage capacity, load balance and the like, and can delete data immediately every other time period, such as deleting once in 3 months. N is the number of deletions, which may be dynamically set according to conditions such as storage capacity and load balancing, or may be a fixed number.
Step 102: the method comprises the steps that a sharing server receives a first query request which is sent by external query equipment and used for querying first real estate registration information; the first query request comprises query requirement information of the first real estate and the first verification code which are generated by the query device after being encrypted according to the random public key.
In this embodiment, the first authentication data is obtained by encrypting the first random number and the first authentication code by the authentication device according to a first private key stored in advance. The method comprises the following steps:

the verification server judges whether the verification equipment is legal equipment or not according to the equipment ID;
if the verification equipment is illegal equipment, the verification server feeds back a verification result comprising that the verification fails to pass to the verification equipment; if the verification device is a legal device, inquiring a first public key corresponding to the verification device according to the device ID, and decrypting the first verification data by adopting the first public key to obtain a first random number and a first verification code;
the verification server generates a second verification code according to the generation time of the first random number and by combining a preset second algorithm, and judges whether the second verification code is the same as the first verification code or not;
if the random public key and the random private key are the same, the verification server generates a random public key and a random private key which are matched with each other, and the random public key is sent to the verification equipment; if not, the verification server feeds back a verification result including verification failure to the verification device.
In this embodiment, the second verification code is generated by the verification server according to the generation time of the first random number and by combining a preset second algorithm. The first algorithm and the second algorithm are substantially the same set of algorithm, and the function of the algorithm is to generate the verification codes according to the generation time of the first random number and perform secondary verification by comparing whether the two verification codes are consistent or not, so that the safety of verification is further improved.
In this embodiment, the random public key and the random private key refer to a pair of keys that are randomly generated by the authentication server and matched with each other. Each sharing query generates a pair of random keys, so that the encryption and decryption of the whole process are not influenced while the security is ensured.
In this embodiment, after generating the random public key, the verification server generates a random private key matched with the random public key, sends the random public key to the verification device, and forwards the random public key to the query device.
Step 102: the sharing server receives the first random number, the second verification code and the random private key sent by the verification server, and obtains the query requirement information and the first verification code of the first real estate after decrypting the first query request according to the random private key.
In this embodiment, the sharing server decrypts according to the random private key, and if decryption fails, it indicates that the query request is a fake request, and settles the sharing query.
Step 103: and the shared server inquires whether the stored real estate registration information contains information matched with the first real estate or not according to the inquiry requirement information when the first verification code and the second verification code are the same. If yes, go to step 104, otherwise, go to step 105.
In this embodiment, the verification code obtained after decryption is compared with the received verification code, so that the query request can be determined twice, and the security of the shared query is further improved.
Step 104: and the sharing server feeds back a first query result to the query equipment according to the queried real estate registration information and in combination with the query requirement information.
In this embodiment, if the shared server queries the corresponding real estate, a corresponding first query result is generated according to the query requirement information, and is sent to the query device.
Step 105: the sharing server forwards the query requirement information to the intranet server, so that the intranet server can query and feed back a second query result according to the query requirement information, and then the sharing server feeds back the second query result to the query equipment.
In this embodiment, if the shared server does not query the matched real estate, it indicates that the real estate has not been subjected to business processing for a long time, and the intranet server performs secondary query to ensure the integrity of each query and ensure the reliability and security of the shared query process.
As an example of this embodiment, the method for shared query according to the present invention further includes: the network server sorts all real estate registration information stored by the network server according to the registered land area of the real estate from small to large to obtain a first sorting table; and the intranet server performs sequencing optimization on the first sequencing list according to the type of each real estate to obtain a second sequencing list, and manages all real estate registration information through the second sequencing list.
In this example, if step 105 is executed, step 105 specifically includes: and the intranet server inquires the real estate registration information corresponding to the first real estate according to the second sorting table and the inquiry requirement information and generates a corresponding second inquiry result. The intranet server of this example will be to all real estate registration information of its storage, will sort according to the registration land area earlier, and carry out the sequencing optimization according to the type of real estate again, makes real estate registration information number quantization, when data management and shared inquiry, can carry out preliminary screening to real estate, reduces the data total, carries out accurate inquiry to data again, further improves the speed of whole shared inquiry.

the intranet server sorts all real estate registration information stored by the intranet server from small to large according to the registered land area of the real estate to obtain a first sorting table;
and the intranet server performs sequencing optimization on the first sequencing list according to the type of each real estate to obtain a second sequencing list, and manages all real estate registration information through the second sequencing list.
6. The real estate information sharing query method according to claim 5, wherein the intranet server queries and feeds back a second query result according to the query requirement information, specifically:
and the intranet server inquires the real estate registration information corresponding to the first real estate according to the second sorting table and the inquiry requirement information and generates a corresponding second inquiry result.
7. A real estate information sharing query system, comprising: the real estate information sharing system, the real estate registering system, the verification server, the verification equipment and the inquiring equipment; the real estate information sharing system comprises an intranet server and a sharing server;
when the real estate information sharing system receives a real estate registration entry request sent by the real estate registration system, the content of the entry request is stored in the intranet server and the sharing server respectively; all real estate registration information in the shared server is provided with an entry timestamp; the sharing server manages the internal storage data according to the input timestamp;
the query equipment generates query requirement information of a first real estate to be queried according to a query instruction, generates a first random number corresponding to the query instruction, and records generation time of the first random number;
the inquiry equipment sends the first random number and the generation time of the first random number to the verification equipment;
the verification equipment generates a first verification code according to the generation time of the first random number and by combining a first algorithm preset in the equipment, and encrypts the first random number and the first verification code according to a first private key stored in advance to obtain first verification data;
the authentication device initiates a first authentication request to the authentication server, wherein the first authentication request comprises: the first authentication data, a device ID of the authentication device, and a generation time of the first random number;
the verification server respectively verifies the first verification data and the equipment ID of the verification equipment, and if the first verification data and the equipment ID of the verification equipment both pass the verification, the verification server generates a random public key and a random private key which are matched with each other; otherwise, the authentication server feeds back an authentication result comprising authentication failure to the authentication device;
after the random public key is generated, the verification server sends the random public key to the verification device so that the verification device can forward the random public key to the query device; the authentication server further sends the first random number, the second authentication code and the random private key to the sharing server; the second verification code is generated by the verification server according to the generation time of the first random number and by combining a preset second algorithm;
after receiving the random public key, the inquiry equipment encrypts inquiry requirement information and a first verification code of the first real estate according to the random public key to generate a first inquiry request and sends the first inquiry request to the sharing server;
the sharing server decrypts the first query request according to the random private key to obtain query requirement information and a first verification code of the first real estate;
the shared server inquires whether the stored real estate registration information contains information matched with the first real estate or not according to the inquiry requirement information when the first verification code and the second verification code are the same;
if so, the shared server feeds back a first query result to the query device according to the queried real estate registration information and in combination with the query requirement information;
if not, the sharing server forwards the query requirement information to the intranet server so that the intranet server can query and feed back a second query result according to the query requirement information, and then the sharing server feeds back the second query result to the query equipment.
