Title: BLOCKCHAIN TECHNOLOGY-BASED ROBUST ATM NETWORK SYSTEM AND INFORMATION PROCESSING METHOD THEREFOR
Abstract:
The present invention relates to a blockchain technology-based robust ATM network system and an information processing method therefor. The information processing method comprises the following steps: an ATM node generating transaction information; after performing specified processing on the generated transaction information, the ATM node performing block packaging to generate blockchain information; the ATM node broadcasting the blockchain information to an entire network; a server serving as a monitoring node to regularly synchronize the blockchain information in an ATM network; and the server analyzing the blockchain information and storing the same. In the present invention, the server can serve as a monitoring node to directly synchronize all information, thereby facilitating aggregation of transaction information. Moreover, use of an asymmetric cryptographic algorithm to perform specified processing on the transaction information ensures security of the transaction information.
