In this specification, a method and a system for auditing a terminal location are provided, and details are described in the following embodiments one by one.
Fig. 1 shows a flowchart of a terminal location auditing method according to an embodiment of the present specification, which specifically includes the following steps:
step 102: the method comprises the steps that a first detection party obtains a first deployment position of a terminal, the first deployment position is mapped to an electronic map, and first deployment area information of the terminal is determined in the electronic map.
The terminal is a payment acceptance terminal, such as a POS machine, a code scanning gun, and the like, and the payment acceptance terminal may be a terminal having a code scanning function, and may also be a terminal for providing a two-dimensional code for a user to use, which is not limited in this specification.
In practical application, the terminal deployment party can be an acquirer, namely the terminal is deployed by the acquirer, the actual deployment position of the terminal is privacy information of the terminal deployment party and is inconvenient to provide to other organizations such as a supervisor and a detector, and the first deployment position is the actual deployment position of the terminal, namely the first detector can accurately acquire the first deployment position.
An electronic map, i.e., a digital map, is a map that is stored and referred to digitally using computer technology, and any position on the earth can be mapped to a corresponding position on the electronic map.
Optionally, the mapping, by the first detector, the first deployment location into the electronic map includes:
the first detection party converts the first deployment position into first longitude and latitude information corresponding to the first deployment position, and maps the first longitude and latitude information into an electronic map.
Specifically, since the first detection party has the first deployment position of the terminal, the first deployment position is correspondingly marked in the electronic map, latitude and longitude information of the first deployment position can also be acquired, and the latitude and longitude information is input into the electronic map, so that the first deployment position is mapped into the electronic map.
Optionally, the determining, by the first detecting party, the first deployment area information of the terminal in the electronic map includes:
the method comprises the steps that a first detection party determines a first grid set in an electronic map according to a preset area radius, and determines first deployment area information corresponding to the first grid set, wherein the electronic map is divided into a plurality of grids in advance, and each grid is provided with a corresponding grid identifier.
Specifically, the preset area radius can be 50 meters, can be 100 meters, can be 200 meters, the actual condition is the standard for the setting of the preset area radius, in order to facilitate the use in the electronic map, a plurality of grids can be divided into in advance for the electronic map, each grid has a corresponding grid mark, the side length of each grid can be 1 meter, also can be 10 meters, also can be 100 meters, the specific side length is also the standard with practical application, the side length of each grid is not limited in the application.
In the embodiment provided in this specification, taking as an example the detection of whether the deployment position of a certain mobile POS is compliant, as shown in fig. 2, fig. 2 shows a schematic diagram of an electronic map in a first detection party, where point a is a terminal deployment party, maps an actual deployment position of the POS to a position in the electronic map, and a circle is drawn on the electronic map with a radius of 50 meters with point a as a center, an area within the circle is a first deployment area, a grid related to the first deployment area is a first grid set, and grid information corresponding to the first grid set is first deployment area information {54, 64, 45, 55, 65, 75, 46, 56, 66, 76, 57, 67}, where the first deployment area information represents a grid number.
Step 104: and a second detection party acquires a second deployment position of the terminal, maps the second deployment position to the electronic map, and determines second deployment area information of the terminal in the electronic map.
The second detection party may be a payment platform, and when the user performs payment operation on the terminal through the payment platform, the payment platform may receive a payment position of the user during the payment operation on the terminal, where the second deployment position is the payment position.
In practical application, in order to ensure the accuracy of the second deployment position, the payment positions returned by a plurality of users when the terminal performs payment operation may be obtained, and an average position may be determined as the payment position according to the payment positions, for example, a plurality of payment positions may be clustered to obtain an average position, or a center position may be obtained by calculation, so that drawing a circle with the center position as a center of the circle may include most payment positions, and the specific calculation method is based on practical application.
After the second deployment position is obtained, the second deployment position is mapped to the electronic map, in order to unify standards, the setting parameters of the electronic map on the second detection side need to be the same as the setting parameters of the electronic map on the first detection side, the electronic maps with the same specification are used, and the lengths of the electronic grids in the electronic map are the same. The method has the advantages that errors caused by inconsistent scales are avoided, subsequent detection errors are further caused, similarly, in the process that the second deployment position is mapped to the electronic map, random disturbance information is added to the longitude and/or the latitude corresponding to the second deployment position, the information interferes with the longitude and latitude information of the second deployment position, certain deviation exists between the second deployment position and the actual position when the second deployment position is mapped to the electronic map, but the deviation range is small, and the second deployment position can be received within the range.
Optionally, the determining, by the second detecting party, second deployment area information of the terminal in the electronic map includes:
and the second detection party determines a second grid set in the electronic map according to the area radius and determines second deployment area information corresponding to the second grid set.
After the second deployment position is mapped into the electronic map, a second deployment area is determined in the electronic map by taking the mapping position of the second deployment position in the electronic map as the center of a circle and a preset area radius, a grid related to the second deployment area is a second grid set, and grid information corresponding to the second grid set is second deployment area information.

Step 106: and the first detection party and/or the second detection party detect whether the first deployment area information and the second deployment area information have an overlapping area or not, and send the detected overlapping result to an auditing party.
In practical applications, there are various ways to detect whether there is an overlapping area between the first deployment area information and the second deployment area information, for example, the second detection party may send the second deployment area information to the first detection party, the first detection party performs detection, and sends the detected overlapping result to the auditing party, or the first detection party may send the first deployment area information to the second detection party, the second detection party performs detection, and sends the detected overlapping result to the auditing party, or the first detection party may send the first deployment area to the second detection party, the second detection party sends the second deployment area to the first detection party, and then the first detection party and the second detection party respectively detect the overlapping result, and send the respective overlapping result to the auditing party, and the following explains the concentration conditions one by one.

The second detecting party obtains the first encrypted data Set and the second encrypted data Set, and the Intersection of the two encrypted data sets can be obtained based on a privacy Protection Set Intersection (PSI) protocol, and the privacy protection Set Intersection protocol allows two parties holding the respective sets to jointly calculate the Intersection operation of the two sets. At the end of protocol interaction, one party or two parties should obtain correct intersection, and any information in the other party set except the intersection cannot be obtained, so that the privacy information of the two parties can be effectively protected.
In one embodiment provided herein, the first detection party encrypts the first deployment region information {54, 64, 45, 55, 65, 75, 46, 56, 66, 76, 57, 67} to obtain the first encrypted data set S1And collecting S the first encrypted data1Sending the information to a second detection party, and encrypting second deployment region information {44, 54, 64, 34, 44, 54, 64, 35, 45, 55, 65, 46, 56 and 66} by the second detection party by using the same encryption algorithm to obtain a second encrypted data set S2The second detection party can obtain the S based on the PIS protocol under the condition that the specific content of the first deployment area information does not need to be obtained1And S2Whether an intersection exists and the size of the intersection are detected to determine S1And S2And an intersection exists, namely the first deployment area information and the second deployment area information have an overlapping area, and the second detector sends a result of the overlapping area to the auditor.

The first detection party obtains the second encrypted data Set and the first encrypted data Set, and the Intersection of the two encrypted data sets can be obtained based on a privacy Protection Set Intersection (PSI) protocol, so that the privacy information of the two parties can be effectively protected.
In a specific embodiment provided in this specification, the second detection party encrypts the second deployment region information {44, 54, 64, 34, 44, 54, 64, 35, 45, 55, 65, 46, 56, 66} along with the above example to obtain a second encrypted data set S2And the second encrypted data set S2To the first detector, theA detection party encrypts the first deployment region information {54, 64, 45, 55, 65, 75, 46, 56, 66, 76, 57, 67} by using the same encryption algorithm to obtain a first encrypted data set S1The first detection party can obtain the S based on the PIS protocol under the condition that the specific content of the second deployment area information is not required to be obtained1And S2Whether an intersection exists and the size of the intersection are detected to determine S1And S2And if no intersection exists, namely the first deployment area information and the second deployment area information do not have an overlapping area, the first detector sends the result of the absence of the overlapping area to the auditor.
In practical application, the PSI protocol may enable both sides to know whether the sets of both sides have the size of the intersection and the size of the intersection, and may not enable the other side to know the specific value in the set of the both sides at the same time, and for the sake of fairness, both sides may send the overlapping result obtained by the detection to the auditing party, specifically, the first detecting party and/or the second detecting party detects whether the first deployment area information and the second deployment area information have the overlapping area, and sends the overlapping result obtained by the detection to the auditing party, including:
