Problems solved by technology

[0003] Among the existing encryption algorithms, the algorithms that can be used for coordinate trajectory encryption are limited, some encryption algorithms are not suitable for coordinate trajectory, and some encryption algorithms cannot be decrypted and restored
In addition, because the length of the coordinate trajectory is often very large, the length of the ciphertext obtained when encrypting with the existing encryption algorithm is also very large, which easily takes up too much storage space and network traffic

Abstract

The invention relates to the technical field of coordinate track encryption, in particular to a coordinate track encryption and decryption method and system. The encryption method comprises the stepsthat a set of character sequence is set randomly as an encryption factor of a current coordinate track, all characters in the encryption factor are different and include multiple special characters and multiple decimal characters; on the basis of the encryption factor, a value of each dimensional of each coordinate in the current coordinate track is converted into a corresponding decimal characteror the combination of a corresponding special character and a decimal character; the decimal characters obtained through conversion and the combination of the special characters and the decimal characters are sorted according to a preset sequence to form an encryption character sequence corresponding to the current coordinate track. The coordinate track is compressed while the coordinate track isencrypted, and the coordinate track is decrypted and reduced.

Description

technical field [0001] The invention relates to the technical field of coordinate track encryption, in particular to a method and system for encrypting and decrypting coordinate track. Background technique [0002] In the Internet field, since the user's coordinate track can often reflect the user's information, generally, the coordinate track needs to be encrypted. [0003] Among the existing encryption algorithms, the algorithms that can be used for coordinate trajectory encryption are limited, some encryption algorithms are not suitable for coordinate trajectory, and some encryption algorithms cannot be decrypted and restored. In addition, because the length of the coordinate trajectory is often very large, the length of the ciphertext obtained when encrypting with the existing encryption algorithm is also very large, which easily takes up too much storage space and network traffic. Contents of the invention [0004] The technical problem to be solved by the present in...
