AI Technical Summary
Existing technologies struggle to effectively identify and block content variations in Chinese spam text messages, resulting in high false negative and false positive rates. Traditional methods are unable to cope with frequent number changes and Chinese character variations, limiting their effectiveness in blocking spam.
A two-layer filtering method is adopted. First, the initial feature value is assigned based on the feature differences of SMS length, phone number, bank account number and URL. Then, intelligent analysis is carried out by using a variant association library based on 6763 Chinese characters and multi-algorithm fusion to build a spam SMS Chinese character information association library for matching and identification.
It significantly improved the accuracy of spam SMS interception, reduced the false alarm rate and the missed detection rate, achieving an interception accuracy of 96.64%, a false alarm rate of 3.36% and a false detection rate of 1.13%, reducing operating costs and improving user information security.
