Abstract

This invention discloses a data classification and grading encryption processing method, electronic device, storage medium, and system, belonging to the field of data security technology. Addressing the risk of information leakage during data classification and grading due to data scanning, this technology deploys a PCIe encryption card in the data classification and grading device to construct a full-process encryption protection system from data entry to storage. This PCIe encryption card, based on a hardware-level encryption mechanism, first performs real-time encryption processing on the raw data entering the classification and grading system before conducting classification and grading scanning operations. The encrypted storage management process and the data classification and grading process proceed in parallel, without affecting the efficiency of classification and grading processing, and completely avoiding the risk of data leakage during scanning, processing, and storage stages, effectively ensuring the security and privacy of core business data.
