The invention 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 fragment according to a watermark fragment number; generating pseudo line data of the target equivalence class based on the attribute values of the k tuples of the data in the target equivalence class and the value of the watermark fragment to be inserted; and respectively inserting the N watermark fragments into the pseudo line data corresponding to the target equivalence class. According to the scheme, the problems that the watermark robustness of existing anonymous structured data is poor, and an index table needs to be established to recover watermark information are solved.
