In conclusion, the technical scheme provided by the invention can simultaneously realize double verification of the identity information of the application terminal accessing the GIS and the type of the service requested by the application terminal, and has higher safety.

In the above embodiment, when the service filtering module determines that each target service type includes the current service type, i.e., the type of service requested by the current application terminal is authenticated, the record processing module may determine the current time, and the current moment is recorded as an access moment corresponding to the current identity information, the frequency filtering module can determine whether the current application terminal has high-frequency access to the target GIS according to each access moment corresponding to the recorded current identity information, and if and only when the current application terminal is determined not to perform high-frequency access on the target GIS, triggering the service filtering module to inquire the corresponding relation stored in the geographic data service library and the subsequent processing process, so as to avoid that the target GIS cannot normally provide map service for other application terminals due to malicious high-frequency access on the target GIS by the intruder by using the current application terminal which passes the double verification.
Specifically, the frequency filtering module may determine whether the current application terminal accesses the target GIS at a high frequency through any one of the following two implementation manners.
Mode 1: the frequency filtering module determines the current access frequency of the current application terminal to access the GIS within a set time period according to at least one recorded access moment corresponding to the current identity information, and determines that the current application terminal does not perform high-frequency access on the target GIS when the current access frequency is not higher than a preset access frequency; otherwise, when the current access frequency is higher than a preset access frequency, it can be determined that the current application terminal performs high-frequency access on the target GIS. It should be understood by those skilled in the art that the preset access frequency may be determined in combination with data read-write performance of the GIS and a reference frequency (which may be an empirical value) at which the application terminal normally accesses the target GIS.
Mode 2: the frequency filtering module inquires each recorded access moment to determine a target access moment adjacent to the current moment, and when the time difference between the current moment and the target access moment is not greater than a set time interval, the current application terminal is determined not to perform high-frequency access on the target GIS; otherwise, when the time difference between the current time and the target access time is greater than the set time interval, it is determined that the current application terminal performs high-frequency access on the target GIS. It should be understood by those skilled in the art that the set time interval may be determined in combination with data read-write performance of the GIS and a reference time difference (which may be an empirical value) when the application terminal normally accesses the target GIS.

Condition 3: and the frequency filtering module determines that the current application terminal performs high-frequency access on the target GIS.
In most service scenarios, a target GIS is deployed in a cloud platform, and in order to ensure that the target GIS can be combined with a map application gateway control system to provide map services to a plurality of application terminals using different protocol types, in an embodiment of the present invention, when the service request carries a protocol type of the current application terminal, the service response module is configured to perform format conversion processing on the read map service data according to the protocol type, and send the map service data subjected to format conversion processing to the current application terminal.
Specifically, the type of the protocol used by the application terminal may be an OGC (Open Geospatial Consortium) standard protocol, and when the service response module performs format conversion on the map service data and returns the map service data to the current application terminal, the service response module may give a geographic information character string according to the protocol standard; the protocol type used by the application terminal can also be a non-OGC standard protocol, and the service response module can directly return in a character stream mode when converting the format of the map service data and returning to the current application terminal.
In one embodiment of the present invention, the method further comprises: configuring a processing module; the configuration processing module is configured to update the geographic data permission base 101 and the geographic data service base 102 according to a trigger of a user. Specifically, the user may negotiate with the target GIS and the owner of one or more different application terminals in combination with the actual service scenario, and perform configuration update on the geographic data permission base and the geographic data service base according to the negotiation result, that is, update the identity information of each application terminal that is allowed to access the target GIS, the service type that is allowed to access, and the correspondence between the service type and the URL address.

8. The system of claim 7,
the determining, by using the frequency filtering module, whether the current application terminal performs high-frequency access to the target GIS according to the recorded at least one access time corresponding to the current identity information includes:
determining the current access frequency of the current application terminal to access the GIS within a set time period by using the frequency filtering module according to at least one recorded access moment corresponding to the current identity information, and determining that the current application terminal does not perform high-frequency access on the target GIS when the current access frequency is not higher than a preset access frequency;
or,
and querying each recorded access moment by using the frequency filtering module to determine a target access moment adjacent to the current moment, and determining that the current application terminal does not perform high-frequency access on the target GIS when the time difference between the current moment and the target access moment is not greater than a set time interval.
9. The method of claim 1,
when the service request carries the protocol type of the current application terminal,
the forwarding the read map service data to the current application terminal includes: and performing format conversion processing on the read map service data according to the protocol type, and sending the map service data subjected to the format conversion processing to the current application terminal.
