Abstract:  In order to design and develop a real-time and efficient remote rescue system to meet the needs of
users in the privacy security, this paper designed and implemented a set of relatively safe API (Application
Programming Interface). The safety interface is through the TLS (Transport Layer Security) technology and
JSON (Java Script Object Notation) Web socket Token verification technology, through the double authentication
mechanism in the HTTP transport layer encryption and user permissions token verification to build relatively safe
access mode for API users. Through the related system security testing and analysis, the system can realize the
security of information transmission interface based on the function of the communication between the monitor and
the monitor, information release and positioning.

Key words: transport layer security(TLS),  Java script object notation(JSON) web token, security application programming interface (API)
