In this paper, architecture of Cellular Neural Networks, biometrics, biometric recognition system, Cellular Neural Networks in fingerprint image preprocessing and fingerprint biometrics recognition is introduced. The paper has studied and conducted an experiment with fingerprint biometrics, input image preprocessing phase where the input biometric image is enhanced. Both preprocessing and recognition phases are realized by means of CNN approaches and proposed forcible application of technology in biometric security relies on the use of Cellular Neural network and biometric in recognition biometric fingerprint authentication virtual private network to improve safety features of the system and conducted an experiment to establish a virtual private network deployed in network management.
