a latitude encryption mode: generating encrypted latitude data by computing the original latitude, the ID, the minute of gps time and the second of gps time;
extern double encryptLatitude(double latitude，int gpsSecond，int gpsMinute，char gpsID[20])；
longitude encryption mode: generating encrypted latitude data by computing the original longitude, the ID, the minute of gps time and the second of gps time;
extern double encryptLongitude(double longitude，int gpsSecond，int gpsMinute，char gpsID[20])。
according to the above, as shown in fig. 1, a gps video track playing system includes a data acquisition device and a video playing device; the data acquisition device is used for acquiring GPRMC data, writing the GPRMC data into a video, and then encrypting longitude, latitude and ID by using a gps module; the video playing device is internally provided with gps video track playing software which is used for analyzing encrypted gps data in a video, verifying the legality of a gps module ID through a server and synchronously playing a video and a driving track on a map, because the data acquisition device can be arranged on a driving recorder and can also be arranged on an unmanned airplane, the system not only can be suitable for the driving recorder but also can be used for the unmanned airplane, the sold gps module ID is registered in the server in advance, when the data acquisition device acquires the data, the data is encrypted through a gps data encryption system and then transmitted to the video playing device, the gps video track playing software in the video playing device can verify whether the ID is legal when playing the video and simultaneously decrypts correct longitude and latitude data, the position of each gps data stored in the video is regular, and the protocol of the gps storage is as follows: mp4, mov format video, stores gps data under moov \ gps box node or gps0 box node, and TS format video, TS packet is mainly composed of two parts, one is 4 bytes of packet header information, the other is payload, in addition, because each packet fixedly needs 188 bytes, PID is important parameter for identifying TS packet, used for identifying TS packet carried data type, make gps data exist in PID {0x0000, 0x0100, 0x1011, 0x1011, 0x1100, 0x0E1B, 0x01E5} labeled data packet, following these technical protocols, able to quickly analyze gps data, then through decryption function, decrypt correct latitude and longitude;
