Abstract

A method for marking the intervals of an input text with extra blanks, generating an output text to be transmitted, is disclosed for the purposes of : encoding and hiding (secret) binary data on the output text, and at the same time encoding and hiding on the output text the integrity information of the input text, and hiding the distribution of blanks (i.e., the format) of the input text. The method enables the receiver, from a received marked text: to recover the (secret) hidden binary data, to recover the original input text, and to verify the integrity of the received text
