access security system based on blockchain processing of biometrics logs for access control equipments

摘要

The present invention generally relates to a technology for access management using biometric authentication and blockchain for medical equipment, hazardous equipment, and high-priced equipment, more particularly, to an access control system which is configured by installing a biometric authentication module on medical equipment, hazardous equipment and high-priced equipment. The biometric access record for the equipment is shared with an administrator computer through a blockchain. If an item incompatible with the real-time status of an access permitted user is detected, it is determined that the risk of abnormal use is high and a security warning is generated so that the access control to the access-controlled equipment can be effectively and securely performed. Accordingly, it is possible to effectively control the use of medical equipment, hazardous equipment, and high-price equipment. In addition, by sharing the biometric access record for medical equipment, hazardous equipment, and high-price equipment with the administration computer in real time through the blockchain, an item incompatible with the real-time status of an access permitted user is detected through software processing and a security alarm is generated immediately. Thus, it is possible to control the abnormal use of equipment effectively and securely.
