ACCESS SYSTEM AND METHOD BY BIOMETRIC IDENTIFICATION AND DATA ENCRYPTION THROUGH CHAOTIC SYNCHRONIZATION IN A MASTER-SLAVE SCHEME.

摘要

The present disclosure is related to an access system to a data access and encryption system through biometric identification and chaotic synchronization in a master-slave scheme. Characterized by comprising an image capture subsystem based on infrared light. The subsystem consists of an infrared spectrum camera for capturing an image of the venous pattern of a finger through a process of transillumination with light in the infrared spectrum; placed on top of the interior of a compartment of a luminous insulation housing. Adapted with a controlled access window in the lower area to allow the entry of a finger. Arranged on a lower platform with a longitudinal groove and a dispersion grid that is coincident with the finger. Configured to allow the controlled passage of infrared light emitted by a lighting subsystem that includes a plurality of infrared LEDs to illuminate in a controlled manner and thus obtain the venous finger pattern. An embedded subsystem integrated in the luminous insulation housing, consists of an electronic card with a central processor with libraries for artificial vision in real time. Libraries to implement protocols dedicated to encryption and memory for the execution of the processing algorithms of venous pattern images. The generation of a biometric key and the encryption-decryption of information based on chaotic dynamic systems.
