Facial feature asabiological pared with others is direct,friendly andco featureemployed in authentication are user-friendly. The technology of face recognition in the past few years obtained the very big deve lopment, but due to the face of nonrigid, expression and changeablefactors, the face reco gnition technology in practical application are facing great difficulties. This paper aimed at home and abroad in recent years the relevant papers and researchreports on study and on the basis of the analysis, some units within the data sensitivity places need to enter p ersonnel to carry out limitation design and develop a set of identity verification identific ation system, the system uses PCA face recognition method, therealization is simple and the accuracy rate of recognition is high,but itsdrawback is that a large amount of calcul ation, when to identify more staff,this method is difficult todo. The realization ofa set of various pretreatment methods inone of the generic face image preprocessing simulation system based on MATLAB, the system is used as the image preprocessing module can be embedded ina face recognition system,
