A data processing system for interacting with large language models, comprising:

• an information system unit, configured to store instructions;
• a calculation core module, configured to execute the instructions of:
• obtaining an original text;
• analyzing the original text and determining a confidential data item in the original text;
• generating a semantic model according to sentence structure, semantic content and contextual information associated with the confidential data item in the original text and converting the confidential data item in the original text into a common word for masking, so as to generate a secure input text;
• inputting the secure input text to a large language model for processing;
• receiving a reply text generated by the large language model based on the secure input text;
• and
• converting the reply text into a target reply text corresponding to the original text for unmasking according to the common word and the semantic model.
