description The invention discloses a geographic information secure transmission method based on differential privacy, which comprises the following steps: S1, conducting differential privacy definition, wherein two adjacent data sets D and D' exist, and the difference between the two data sets is that only one piece of data is different at most; S2, adding noise by using a Laplace function, wherein the mechanism can post-process results of aggregation queries so as to enable the results to be differentially private; S3, performing different fluctuations on the personal geographic information data by adjusting the Laplace function so as to avoid analysis of attackers and not influence use of the personal geographic information at the same time; noise is added by utilizing the Laplace function to enable all geographical position information data of a person to fluctuate in an understandable range, the range of fuzzy personal geographical information data is determined by adjusting specific values of fluctuation and meetin
