Steganographic Information Hiding Method Based on Double Wavelet Transform

The article presents a new method of steganographic embedding of confidential information into an image based on double wavelet transform. This method is a continuation of previous studies based on a one-level discrete wavelet transform. The practical implementation of this method is demonstrated on the example of a graphic file in JPEG format. The article shows the theoretical substantiation of the presented method, the data hiding algorithm and the analysis of the research results.
