What Are the Requirements on the Source Data To Be Watermarked?

Watermark injection is a process to embed atomic watermark information into data with different features. The more source data features, the more complete watermark information can be embedded, and the higher the extraction success rate is. In addition, even if some data is missing, watermark extraction is not affected. The data to be watermarked must meet the following requirements:

• The source data must contain 1000 lines or more.

  If the source data contains less than 1000 lines, the watermark may fail to be extracted due to insufficient features.

• You are advised to select a column with various data values. If all the values of the column can be enumerated, the extraction may fail due to insufficient features.

  Common columns that can be embedded with watermarks include the address, name, UUID, amount, and total amount.
