AI Technical Summary

Technical Problem

Existing printer security solutions rely on software policies that are easily bypassed, and hardware security capabilities are disconnected from business processes, making it impossible to achieve full-process trusted hardware control and traceability of physical output.

Method used

By employing the TCM trusted computing module and combining it with biometric data collection, a cryptographic guarantee is established for the entire process from digital authorization to physical release. Through the collaborative work of the client, printer, and management server, steps such as identity verification, data encryption, and embedding of traceability information are achieved, ensuring that each output hard copy has a verifiable and unique identity.

Benefits of technology

It achieves trusted control over the entire process from digital operation to physical output, preventing data tampering and leakage, ensuring the uniqueness and traceability of each hard copy, and preventing identity theft and leakage of residual data.

Abstract

This invention relates to the fields of information security and printing technology, specifically to an information printing output control and traceability method based on a TCM trusted computing module. The method includes an information printing output control and traceability system comprising: a client with a trusted identity module for collecting and encrypting the printing user's identity information; and a printer with a trusted computing module for verifying its own and its operating environment's trustworthiness, securely storing the root key, performing cryptographic verification and decryption of received encryption tasks, executing "human-to-release" logic control, and generating and embedding traceability information into the printing medium for verifying trustworthiness. Compared with existing technologies, this method establishes an immutable trust chain, achieves end-to-end cryptographic guarantees from digital authorization to physical release, and ensures that each output hard copy has a verifiable and unique identity, preventing the risk of data leakage due to residual data.
