System and method for quickly inquiring about black and white name list

Abstract

The invention discloses a system of quickly inquiring black-and-white list, which comprises the following parts: an inquiring unit for inquiring the exist of the detecting keyword in the black-and-white list, a digit group creating unit for creating the digit group according to the calculated value after calculating all the key words separately in the black-and-white list, a digit group saving unit for saving the digit group created by the digit group creating unit, a matching unit for comparing the calculating value of the detecting key word to the digit group in the digit group saving unit after calculating the detecting key word and making inquiring unit inquire the exist of the detecting key word in the black-and-white list when the calculating value of the detecting key word matches to the digit group. The invention also provides a corresponding method. The invention reduces the access of the black-and-white list in the data base in the inquiring process, which decides the black-and-white list state of the detecting key word quickly.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, relates to a system and method for quickly inquiring black and white lists.
