FIELD: information technology.
SUBSTANCE: text or audio information to be coded is converted to a sequence of combinations of graphic characters of two different types. Combinations of characters and coding letters are interrelated on the pattern with configuration of corresponding letters whose patterns are deposited in cells of a graphical array. The projection of the corresponding letter is positioned onto the graphical array using one type of characters for visible lines and another for invisible lines. Combinations of characters, coding letters or sound are displayed without intervals. The type and mutual arrangement of characters is additionally coded with a digital code.
EFFECT: increased complexity of the decoding process and safety of storage, copying and transmitting confidential information.
