Abstract

The invention discloses a position data protection method based on a time window and position encryption. The method comprises the steps of: enabling a positioning terminal to receive a navigation satellite signal; positioning the navigation satellite signal to obtain positioning data and corresponding time information; respectively encrypting the positioning data and the time information by usingan encryption rule, and then uniformly encrypting the positioning data and the time information; enabling the positioning terminal to push the encrypted data to the server side, and enabling the server side to decrypt the encrypted data after receiving the encrypted data to obtain position data and time data; and comparing the obtained time data with the standard time of the server side, and if the time data in the received data is in a set time window, considering that the position data of the positioning terminal is credible. According to the method, the position information and the time information resolved by the satellite signals are encrypted and compared with the standard time of the server side, so that the credibility of the position information is judged, the position data is prevented from being intercepted and modified on a transmission link, and the purpose of protecting the position information of a user is achieved.

Description

Technical field: [0001] The invention relates to rail transit vehicle teaching equipment, in particular to a position data protection method based on time window and position encryption. Background technique: [0002] In recent years, with the rapid development of wireless communication technology and network technology, the application of location service has become more and more extensive, and will become one of the most important value-added services in the future wireless network. Location service is a kind of wireless network value-added service. It obtains the location information of mobile terminal users through wireless network and related positioning technology, and provides location-related services for users with the support of electronic map platform. For example, car navigation service, mobile phone positioning service, etc. However, traditional location-based services seldom take into account the privacy and security of users. If there are no protection measur...
