Digital Portraits of Suspects Based on a Three-layer Model
A process method was proposed to outline suspect portrait by using algorithm model.This method consisted of a three-layer algorithm model.Firstly,the mobile phone records of suspects were ex-tracted through the data collection layer.Then the parameters of economy,relationship,times and spaces were extracted by using feature extraction layer.Finally,the suspect portrait was constructed through the behavior analysis layer of multiple algorithms.This method obtained the mobile phone records of suspects in specific cases from the grass-roots front-line departments to develop the algorithm model,which broad-ened the application of electronic data in the field of public security investigation.
