A data processing method, device and communication equipment

Abstract

The application provides a data processing method and device and communication equipment, and relates to the field of data security. The method comprises the following steps: anonymizing structured data to meet a k-anonymity requirement, forming a plurality of equivalence classes, and selecting a target equivalence class to be inserted with a watermark slice according to the number of watermark slices; generating pseudo-row data of the target equivalence class based on attribute values of k tuples of data in the target equivalence class and a value to be inserted with a watermark slice; and inserting N watermark slices into the pseudo-row data corresponding to the target equivalence class respectively. The scheme of the application solves the problems of poor robustness of existing watermarking of anonymized structured data and the need to establish an index table to recover watermark information.
