Safety encryption processing system for geographic information data

Abstract

The invention discloses a safety encryption processing system for geographic information data. The safety encryption processing system comprises a processing module and a user module, wherein the processing module comprises a processing sub-module, an encryption sub-module and a reduction sub-module; the user module comprises an authentication sub-module, a destruction sub-module and a display sub-module; the encryption sub-module comprises sequence encryption, plaintext segment encryption and an encryption algorithm; and the destruction sub-module comprises abnormal login clearing, regular clearing and normal login clearing. According to the safety encryption processing system, a plaintext of the geographic information data is segmented and sequenced in the first place, different encryption algorithms are adopted for a preface and a data text, therefore, the data text cannot be normally viewed by independently cracking the sequence secret key and the data normal secret key, the security of the encrypted data is higher, the geographic data is automatically destroyed when abnormal login and login of a second-level account occur by setting the multi-level account and the destructionsub-module, the situation that the geographic data is stolen is reduced, and a user selects a proper destroying mode according to the environment.

Description

technical field [0001] The invention relates to the technical field of geographic information data, in particular to a safe encryption processing system for geographic information data. Background technique [0002] Geographical data is data directly or indirectly related to a certain location relative to the earth. It is a file of various elements that represent geographical location, distribution characteristics of natural phenomena and social phenomena, including physical geographic data and socioeconomic data, such as land cover type data. , landform data, soil data, hydrological data, vegetation data, residential data, river data, administrative boundary and socio-economic data, etc., the data are all regional characteristics, after the data is recorded and stored, in order to prevent it from being stolen by non-users , usually encryption processing is performed to encrypt plaintext data into ciphertext; [0003] However, the existing secure encryption processing syste...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a safe encryption processing system for geographical information data, which can effectively solve the problem that the existing safe encryption processing system for geographic information data proposed in the background technology only encrypts through an encryption algorithm, and its encryption depends entirely on the algorithm itself. After the key is known, it is still prone to the problem of geographic information data leakage
