| Zusammenfassung: | The invention discloses an urban basic surveying and mapping data secrecy processing method. The secrecy processing method comprises the following steps: S1, acquiring the urban basic surveying and mapping data; S2, splitting the urban basic surveying and mapping data to obtain a plurality of metadata packets; S3, setting a common key between any two metadata packets, and encrypting the two metadata packets by using the common key to obtain an encrypted element; s4, allocating a legal holder to each metadata packet; S5, enabling the legal holder to set a private key; S6, enabling the legal holder to compress all encryption elements corresponding to the held metadata packet to obtain a compressed data packet; and S7, enabling the legal holder to encrypt the compressed data packet by using the private key. The secrecy processing method for the urban basic surveying and mapping data is higher in safety.
本发明公开了一种城市基础测绘数据保密处理方法，包括如下步骤：S1、获取城市基础测绘数据；S2、对城市基础测绘数据进行拆分，得到若干个元数据包；S3、在任意两个元数据包之间设置共有密钥，并且利用共有密钥对两个元数据包进行加 |
