Information exchanged between two parties is often targeted by a third party. Steganography in images is often used for handling threats, such as, in this case, an attacker suspecting the existence of confidential information. But even in this case, if a pattern is used, e.g., hiding the information in successive or every third pixel, the attacker might discover the pattern, and the following revelation of the secret information will cause no difficulties. To avoid such vulnerabilities, the information is hidden in the frames of graphical animation. In the frames, the positions of the pixels selected to store confidential information in the given work are determined by the values of a mathematical function. These actions will ensure the high secrecy of information.
