Abstract
A method for exchanging hidden secret messages includes generating a masking message comprising a quick phrase on a sender's mobile device; receiving a secret message and associating it with the masking message; encrypting the masking message; encoding the secret message using invisible symbols and embedding it into the masking message; sending the masking message to a recipient; receiving a response masking message from a recipient's mobile device; copying the response masking message and detecting the secret message by checking a clipboard content; decrypting the response masking message; and decoding the secret message and rendering it on a sender's keyboard screen. The secret message contains an invisible marker inserted after a first symbol of the masking message for detection and decoding.
