Abstract
A method for displaying encoded image data includes providing data in an encoded form, the data when displayed forming a two-dimensional image. Using a decoding cellular automaton rule and a predetermined secret key, the data is processed through a plurality of iterations to obtain the data in a non-encoded form. A series of images resulting from the processing, and ending in the two-dimensional image, is displayed in time-sequence. The series of images contains information that is insufficient for determining the secret key, given knowledge of each one of the decoding cellular automaton rule, the data in the encoded form and the data in the non-encoded form.
