PROBLEM TO BE SOLVED: To provide a method and a device for embedding/extracting information, with which the creator or distributor of a language column can easily embed desired information, simultaneously, a reader or user hardly notices the existence of that information and further, the information can be surely extracted on the basis of a prescribed system, and to provide a recording medium. SOLUTION: Significant information is embedded by changing the position relation of a line end character group and a line shift position comprising a character unit close to the terminal of each of rows in the language column. A language column capable of substantial print/display or electromagnetically recorded language column can be defined as an object for the language column as well. The character unit can be a division by a morpheme as well. A method is provided for extracting information from the language column prepared/ outputted by such an information embedding method. Then, a device for embedding/extracting information and a recording medium for recording the language column are provided. |
