| titleOfInvention | Privacy protection method for user movement track similarity comparison |
| abstract | The invention discloses a privacy protection method for comparing the similarity of user movement tracks, which mainly comprises two stages: firstly, the collection and data quantification of the movement tracks of a user in the daily life and working areas of the user in different unit time periods are completed, and the position change and the movement tracks of the user are represented from two dimensions of time and space by adopting a matrix mode; and then introducing a privacy protection server to realize privacy protection, wherein the method is based on a user movement track matrix, the similarity of the user A and the user B on position change can be analyzed, and the users with high similarity can be considered to be in the same community. However, the position track is privacy data for the user, and then how to complete similarity comparison under the premise of privacy protection is designed, and finally the similarity of the movement track between different users is compared. The invention quantizes the position moving track of the user in two dimensions of time and space, constructs a track matrix capable of realizing lightweight privacy protection, and reduces complexity. |
