Embodiment 1

[0035] Design of watermarking mechanism for numerical relational database:

[0036] A data desensitization method for address information, specifically comprising the following steps:

[0037] Step 1. Address Resolution

[0038] Analyze the address of the data to obtain the corresponding latitude and longitude information;

[0039] Address information usually obtains latitude and longitude information from the structured address detailed to the street, for example: "No. 27, Zhongguancun South Street, Haidian District, Beijing" address analysis result is longitude: 116.31985, latitude: 39.959836.

[0040] Step 2. Perform desensitization operation

[0041] According to the current system configuration, desensitize the address latitude and longitude information analyzed in step 1. The supported desensitization algorithms include but not limited to dithering, random scrambling, fuzzing and other algorithms;

[0042] The dithering algorithm is expressed as follows:

[0043] f(x...

Embodiment 2

[0057] An embodiment of a desensitization method for address information of the present invention includes the following steps:

[0058] Step 1: Call Baidu Maps GeocodingAPI to analyze the input address and obtain the latitude and longitude information of the input address.

[0059] Step 2: Select a desensitization algorithm according to the configuration, and the default algorithm is the dithering algorithm.

[0060] Step 3: Desensitize the latitude and longitude values ​​to obtain the desensitized latitude and longitude values

[0061] Step 4: Check the latitude and longitude information obtained in step 3. The default inspection range is the country. Check whether the latitude and longitude coordinates generated in step 3 belong to the same country as the input address. If the check fails, repeat step 3.

[0062] Step 5: Call the Baidu Maps Geocoding API for the qualified latitude and longitude coordinates obtained in step 4 to perform address reverse analysis, format the ...

Embodiment 3

[0064] Taking "No. 202, Building 17, Tianjiao, Longhu Times, Hexin Road, High-tech West District, Chengdu" as an example, the steps to desensitize this address are as follows:

[0065] Through Baidu map API address analysis query, the longitude and latitude of the input address are 30.759466, 103.925618;

[0066] Select the desensitization method, here the dithering algorithm is selected by default;

[0067] The longitude and latitude after desensitization are calculated by the jitter algorithm: 30.5753960000, 104.3465050000;

[0068] Perform a boundary check on the address coordinates, by default check whether it belongs to the same country as the input address;

[0069] Call the Baidu map API to reverse-analyze the obtained latitude and longitude, and get the result address: Taoyuan Village, Taiping Town, Shuangliu County, Chengdu City, Sichuan Province.

Abstract

The invention relates to a data desensitization method for address information, which belongs to the field of computer security. The method includes address resolution, coordinate shaking and reverse resolution of addresses. According to the characteristics of geographic location information, the present invention can perform desensitization operation on address information. While protecting sensitive information, the correctness of address information format after desensitization can be maintained, and the traditional desensitization algorithm can effectively avoid garbled codes or incomprehensible returns. String and other issues. At the same time, the location boundary can be set to prevent the desensitized data from crossing the boundary and causing the desensitized information to be untrue.

Description

technical field [0001] The invention relates to the technical field of privacy protection and security, in particular to a data desensitization method for address information. Background technique [0002] With the rapid development of all walks of life, the vigorous development of national informatization construction, and the increasingly common application of IT systems, a large amount of sensitive information and data have been accumulated within the enterprise. And these data will be used in many work scenarios of enterprises. For example, business analysis, development testing, and even some outsourcing businesses use real business data and information. These sensitive data are like a time bomb, once leaked or damaged. Not only will it bring great losses to the company, but it will also have a huge negative impact on the company's image. [0003] The concept of Data Masking was first proposed by Adam and Wortmann in 1989. With the development of related technologies...
