The invention relates to the field of big data and discloses a data desensitization method for preventing privacy leakage. The method specifically includes the following procedures: according to the same index field between different data tables of the database, removing the explicit association; defining cryptographic functions for the index fields between the data tables to process the association IDs; calculating the association ID value according to the cryptographic function, and performing the data access after the association ID value is written. The technical scheme of the invention mainly adopts the thinking of cryptography, carries out the algorithm processing to the data table correlation field, and removes the strong association coupling between different tables and different data and user information in database, so it is impossible to know the association between data and information, and the relationship between data and user can not be confirmed even under the conditionof obtaining super privilege of user database, and the privacy protection of data is realized. This method can effectively prevent the privacy leakage caused by the direct access to the database caused by platform attacks, insider and so on.
