Summary:Excel documents are widely used in finance, scientific research, data analysis and statistical reporting, and play an increasingly important role in education and training, online offices and many other scenarios, but they also pose security risks such as unauthorised use, infringement and information leakage.To protect the security of digital content of Excel documents, there is a vital need to develop more secure and reliable document watermarking algorithms.This paper proposes a source tracing multilayer watermarking algorithm for Excel documents with good invisibility and robustness based on the Excel document format.By embedding multilayer watermark information into the cell style and RGB color values of the border of Excel documents, it can clarify the document distribution chain in practical application scenarios, trace the source of document leakage and locate the person responsible for the leakage.The proposed algorithm can be used to reduce the occurrence of information leakage.Experimental comparis
