The information construction and application of public safety is an important step towards the revolution of public security work. It is a significant way to improve overall combat effectiveness, enhance capabilities of grass-root organizations, and it is an important link towards the reformation of the police mechanism. With the rapid development of economic and various social activities, the transient population has been on the increase, which has induced a rise in the number of criminal cases and security cases. This poses great challenges for public safety and increases the responsibilities and obligations of police organizations. Therefore, national public security departments have actively carried out scientific research to develop, practice and improve modernized methods of public safety.
