This invention discloses a
data security encryption system for
passbook printing based on a large-
scale model, comprising: a
data acquisition and encapsulation module for acquiring the
passbook data to be printed; a semantic
parsing and field-level
encryption strategy generation module for inputting the data to be encrypted into an LLaMA semantic model for semantic
parsing; a session establishment module for two-way
authentication; a task context generation and anti-replay management module for constructing a task context; a field-level
encryption and binding module for deriving a task key and obtaining
ciphertext for sensitive fields; an integrity
verification and signature module for generating an integrity
verification digest and a print request message; and a device-side
verification, decryption, and printing module for decrypting the
ciphertext for sensitive fields and executing
passbook printing. This invention combines large-
scale model semantic analysis technology with multi-channel encryption and anti-replay mechanisms, possessing advantages such as high intelligence, fine-grained encryption, strong anti-
attack capabilities, and applicability to multi-terminal scenarios.
