The invention discloses an intelligent credit
bank system and a cross-school credit mutual recognition method, and the architecture of the intelligent credit
bank system is composed of a data
perception layer, a federal learning layer, a block chain evidence storage layer, and an application
service layer. The data
perception layer is used for carrying out collection, edge preprocessing and desensitization
processing on structured data and unstructured achievement data with diversified sources, and the federal learning layer is used for constructing a
global model so as to carry out
score evaluation and equivalent credit calculation on the same class of courses of each school and realize cross-school achievement mutual recognition. The block chain
certificate storage layer adopts a main chain and
side chain collaborative double-chain architecture, the main chain is used for storing core certificates including credit hash and token transaction, the
side chain is used for
processing high-frequency services, and the application
service layer provides functional interfaces for users and institutions and is in
butt joint with an external
system. According to the method,
data privacy protection is realized by utilizing
federated learning and block chain security cooperative calculation, and the adaptability of the model to different scenes is improved while
privacy protection is realized.
