FIELD: data processing.
SUBSTANCE: invention relates to a method for steganographic text coding. Method of steganographic coding of text comprises the following steps. Text of message is received from server and sent to text processing unit, text processing unit performs binarization of received message text and transmits received binary code to coding unit. By means of the coding unit: dividing the text of the document into a sequence of words with size of n+1, each of which contains at least 3 letters; encoding words by changing the letter-spacing interval towards decrease or increase from the initial one, depending on the pre-set settings; if the word is a unit, the letter spacing is increased by a predetermined value; if the word represents zero, the inter-letter interval is reduced by a predetermined value; if the word in the sequence follows the n-th, then increasing or decreasing the letter-spacing interval by a predetermined value, which must differ from the value received for zeros and ones, this word determines completion of previous sequence and beginning of next sequence; encoded message text is received and transmitted to a text processing unit. Text processing unit transmits coded text by message of document to user display device.
EFFECT: technical result is to provide automatic implicit encryption of message text protection.
