Risk control list storage and rapid query method

The invention discloses a risk control list storage and rapid query method, and relates to the technical field of computer software application. Firstly, rows and columns of a two-dimensional array are set according to the data volume of a to-be-stored list; loading list data into a determinant, placing the list at a specified position after two times of hashcode, and setting the position as 1; and processing and querying the authenticity of the corresponding position according to the inserted data, firstly finding the corresponding row and column position according to the same double-hash method, taking out the value of the position, judging whether the position is true or not, if the position is 1, returning true, and otherwise, returning false. According to the method, the storage space of the data can be reduced, the calling efficiency and the query efficiency are improved, network congestion caused by too large data is avoided, and the application prospect is wide. 本发明公开了一种风控名单的存储及快速查询方法，它涉及计算机软件应用技术领域。首
