A method of unauthorized access prevention to a restricted object and a biometric security identification system are disclosed. The method comprises steps of sending a restricted object identification signal by its access point, approaching a portable biometric fingerprint-coding device to the access point, receiving this signal by the portable device, switching the portable device to send the biometrical fingerprint coded signal of the user to the approaching access point, verifying whether the received biometric fingerprint coded signal matches one of previously provided by authorized persons. The restricted object identification signal and the biometric fingerprint coded signal are the short-range signals acceptable to prevent them to be eavesdropped and cloned. A biometric security identification system comprises a portable biometric fingerprint-coding device for sending a biometrical fingerprint coded signal of the device user, and an identification manager being set in a restricted object for the coded signal detection and its identification.
