Steganography and encrypting were demonstrated with immuno‐specific systems. IgG‐proteins were used as invisible ink developed with complementary antibodies labeled with enzymes producing color spots. The information security was achieved by mixing the target protein‐antigens used for the text encoding with masking proteins of similar composition but having different bioaffinity. Two different texts were simultaneously encoded by using two different encoding proteins in a mixture. Various encrypting techniques were exemplified with the immuno‐systems used for the steganography. Future use of the developed approach for information protection and watermark‐technology was proposed. Scaling down the encoded text to a micro‐size is feasible with the use of nanotechnology.
