description The invention relates to a text watermark generation method and a text verification method. The text watermark generation method comprises the following steps: acquiring an original text, and selecting a key field from the original text; determining at least one text position of the key field appearing in the original text; generating watermarks according to fields in respective neighborhoods of the at least one text position, and obtaining watermark information corresponding to respective neighborhoods of the at least one text position; generating watermark information corresponding to the key field based on the watermark information corresponding to the respective neighborhood of the at least one text position; and generating a text watermark corresponding to the original text based on the watermark information corresponding to the key field. The text verification method comprises the steps of obtaining a to-be-verified text, extracting a to-be-verified text watermark from the to-be-verified text by using a
