The text watermarking method comprises inputting encryption variable set information with which to encrypt a target document, wherein the target document includes text, generating an encrypted block based on the encryption variable set information and embedding the encrypted block into the target document by using an embedding rule of the encrypted block. The encryption variable set information includes a predetermined random key value, a user ID, and information indicating the embedding rule of the encrypted block. The predetermined random key value and the information indicating an embedding rule of the encrypted block are managed in a non-disclosure manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Text watermarking method and apparatus for hiding information into text documents","description":"One aspect of the present invention discloses a text watermarking method for hiding user information.
