Text processing method and device

Abstract

The invention provides a text processing method and device, and the method comprises the steps: obtaining a to-be-printed text, a first electronic seal and anti-counterfeiting data when an instruction type of a received processing instruction is an anti-counterfeiting type; transcoding the anti-counterfeiting abstract information obtained from the anti-counterfeiting data to obtain an abstract code sequence; determining a first seal width of each text page based on the abstract coding sequence, the to-be-sealed text and the first electronic seal; cutting the first electronic seal based on each first seal width to obtain a first straddle seal; and performing pixel random disturbance processing on the first straddle seal to obtain a second straddle seal, adding the second straddle seal to the to-be-printed text to obtain an anti-counterfeiting text, and generating text abstract information corresponding to the anti-counterfeiting text. According to the invention, the anti-counterfeiting abstract information is embedded into the electronic seal, and pixel random disturbance processing is carried out on the straddle seal, so that the straddle seal is prevented from being forged, and the probability that the content of the file is replaced and stolen is further reduced.

Description

technical field [0001] The invention relates to the technical field of electronic seals, in particular to a text processing method and device. Background technique [0002] In daily life, in order to ensure the non-repudiation of paper documents, a physical seal is usually stamped on multiple pages of paper documents, and only a part of the physical seal is stamped on each page. Multiple pages can be combined to obtain a complete document. The physical seal of the paper document, so as to ensure that a certain page or pages of the paper document will not be replaced. This kind of seal stamped on the paper document is called a seam stamp. [0003] With the development of Internet technology and its application in daily life, more and more paper documents are becoming electronic. In order to ensure the authenticity, integrity, confidentiality and non-repudiation of electronic documents, electronic seals are usually used in electronic documents. Stamped with a seam seal. The ...
