The relevance of the study is due to the fact that protecting valuable documents from unauthorized copying and falsification is an important task in the modern world. In this regard, this article proposes a computational method for visualizing information hidden in an image, based on a modification of the known method for detecting and controlling latent images, the elements of which are highlighted by algorithms for varying the direction of lines and wavelet transformation of the document file. The difference between the developed method lies in the preliminary determination of the type of the analyzed image with an embedded hidden message, based on perceptual hash functions. Depending on the type of hidden information, the corresponding transformation of the image is performed using a previously defined wavelet characteristic of this type. This approach reduces rendering time by 3 times. An experiment was carried out to test the proposed method, during which a comparison was made of the visualization of digital images by the known method and the developed modified one with a predetermined type of image. As a result of the experiment, it was found that the computational method can reduce time costs by 3 times. However, this is not the final result, from the theoretical model it follows that the computational method for controlling hidden information in the image can reduce the time spent up to 6 times. This statement is planned to be confirmed experimentally using more types of digital images.
