PURPOSE: A disabling method of image recovery through the encoding based on wavelet disabling data is provided to disable recovery to original data through the modification of a part of data. CONSTITUTION: A pixel value is converted into a specific value before analyzing an original image in the use of wavelet conversion. The converted original image is analyzed to the minimum level through the conversion of the wavelet conversion. The analyzed images are converted through inverse wavelet transformation. |
