企业敏感数据分类分级与风险管控算法模型

算法核心逻辑：
融合关键词匹配、正则表达式校验、多维度数据特征提取（含格式规范、字段长度、语义关联度）三大技术路径，构建 “规则 + 特征” 双驱动的敏感数据自动识别引擎，实现对身份证号、银行卡号、财务数据、客户隐私信息、员工敏感信息等疑似明文数据的精准识别与标记。
建立 “敏感度（高 / 中 / 低）- 业务重要性” 二维分类分级算法框架，内置金融、制造、政务等多行业敏感数据分类模板，支持企业通过可视化配置自定义敏感数据范围及分级阈值，形成动态适配的分类分级规则库。
嵌入风险实时监控算法，基于识别结果跟踪敏感数据全生命周期流转轨迹（采集、存储、使用、传输、销毁），自动触发异常访问、违规传输等风险预警，形成闭环管控机制。
配套规则体系：
敏感数据分类分级规则：明确分级判定标准、自定义配置流程、规则更新迭代机制，确保分类分级结果的一致性与准确性。
权限校验规则：规范敏感数据访问凭证的权限分级、校验流程，实现 “分级管控、最小权限” 的访问控制逻辑。

Core Algorithm Logic:
Integrating three technical approaches including keyword matching, regular expression verification, and multi-dimensional data feature extraction (covering format specifications, field length, and semantic relevance), a "rule + feature" dual-driven automatic sensitive data recognition engine is constructed, enabling accurate identification and marking of suspected plaintext data such as ID card numbers, bank card numbers, financial data, customer privacy information, and employee sensitive information.

A two-dimensional classification and grading algorithm framework based on "sensitivity (high/medium/low) - business importance" is established, which is built with sensitive data classification templates for multiple industries including finance, manufacturing, and government affairs. It supports enterprises to customize sensitive data scope and grading thresholds via visual configuration, forming a dynamically adaptable classification and grading rule base.

Real-time risk monitoring algorithms are embedded, which track the full-life-cycle circulation trajectory of sensitive data (collection, storage, use, transmission, destruction) based on recognition results, automatically trigger risk warnings such as abnormal access and unauthorized transmission, and build a closed-loop control mechanism.

Supporting Rule System:
- Sensitive data classification and grading rules: Clarify grading judgment standards, custom configuration processes, and rule update and iteration mechanisms to ensure the consistency and accuracy of classification and grading results.
- Permission verification rules: Standardize permission grading and verification procedures for sensitive data access credentials, realizing the access control logic of "hierarchical control and least privilege".
