Abstract: With the in-depth utilization of geographic information, the conflicts in geographic information become severe between the requirements of high-precision wide-security-range protection and the requirements of sharing from current economy development. Therefore, sharing geographic information to the maximum under safe conditions has become an important issue, which is to be solved urgently. Consequently, the reliable protection techniques are in urgent demand for protecting the security of geographic information. In this paper, the recent progress of security techniques for geographic information has been reviewed, including the encryption techniques to convert the data into cipher text, the digital watermarking techniques for copyright protection and traceability, the security control techniques for term of validity and permission, the confidential treatment techniques for reducing the data precision and deleting the security property, and the certifiable block chain techniques for tamper proof. Then, the utilization of security techniques in protection for geographic information is discussed. Finally, the future developing direction and the key problems to be further solved are prospected for security techniques of geographic information.
