Abstract

The present application relates to a data processing method, apparatus, computer device and storage medium. The method includes: screening sensitive transactions including sensitive itemsets from a database; taking different combinations in the sensitive affairs to obtain the combination of the sensitive affairs; obtaining multi-objective functions, each sub-objective function of the multi-objective function being respectively used for representing the negative influence degree of each negative influence after the transaction in the database is deleted; screening out one or more sensitive transaction combinations belonging to each optimal solution of the optimal solution set of the multi-objective function from the sensitive transaction combinations, a sensitive transaction combination belonging to an optimal solution being used for minimizing the global negative impact represented by the multi-objective function after being deleted from the database; when a final optimal solution isdetermined from the set of optimal solutions, deleting each sensitive transaction in a combination of sensitive transactions belonging to the final optimal solution from a database. The scheme of thepresent application reduces the negative impact of cleaning the database.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method, device and computer equipment. Background technique [0002] With the rapid development of science and technology, the era of big data is gradually coming. Various data mining techniques are gradually applied to the data mining of the database to reveal the hidden information in the database. However, when data mining technology is used to mine hidden information in databases, private data or security data are often discovered, which leads to security problems. [0003] In order to improve the security of data mining, traditional methods will hide all sensitive itemsets by deleting transactions in the database based on whether to completely hide sensitive rules, so as to clean the database, and then perform data mining processing based on the cleaned database. It can be understood that deleting transactions will inevitably affect the accuracy...
