Under what condition are you permitted to use a new digital encoding technique that you developed to transmit data over amateur radio bands?

Amateur radio regulations strictly prohibit the use of secret codes or ciphers intended to obscure the meaning of a message. If you develop a new digital encoding technique, you may use it only if the technical details are published in the public domain. Publishing the technique ensures that anyone, including regulatory bodies, can decode and monitor the transmission. Distractors like commercial traffic or music streaming are incorrect because they are universally prohibited on amateur bands, regardless of the encoding used.
