Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] Such as figure 1 , a mobile user abnormal behavior detection method, its technical solution is: comprising the following steps:
[0041] S1. Train the data set and establish a normal behavior database;
[0042] S2. Use the sliding window model to obtain the data set X within the mobile user window range, and use the fractal-based clustering fusion algorithm to obtain the clustering fusion result Γ of the data set X;
[0043] S3. Anomaly detection process:
[0044] S301. The cluster fusion result Γ obtained in the S2 step and the N normal behavior data P={P in the normal behavior database in the S1 step 1 ,P 2 ,...,P N} to convert the correlation matrix to obtain the corresponding correlation matrix M={M 1 , M 2 ,...,M N};
[0045] S302. To the N normal behavior data P={P in the normal behavior database in the S1 step 1 ,P 2 ,...,P N} to calculate the...
