The paper describes a new steganography protocol using polymorphic keys for hiding secret information. Such keys will be created from a set of individual hiding keys, designed to disperse several different secrets. Obtained polymorphic keys will be created as a result of combination the individual basic keys, and will be able to be transformed into several different steganographic in such manner that each of them will allow hide and reveal a different input secret information. Individual personalized keys will be created using a fuzzy vault technique. The paper will also discuss the applicability of such steganographic solutions.
