Research on Intelligent Sensitive Data Recognition and Annotation Technology Based on Long Text

With the rapid development of information technology, the widespread dissemination of long text data in cyberspace has brought challenges to personal privacy and information security. This study aims to develop an intelligent sensitive data recognition and annotation technology for long text content. By integrating natural language processing (NLP) technology with machine learning algorithms, we propose an efficient recognition framework that can accurately extract and annotate sensitive information from long texts. The research results indicate that the framework performs well in processing long text data, effectively improving the accuracy of sensitive data recognition, and providing solid technical support for privacy protection and data security.
