When passing photos containing privacy to others, the photos are usually coded, but the mosaics added by the usual method destroy the pixel data of the photos and are difficult to recover accurately.
After using this software to code the photo, you only need to provide the correct password to decode the area with mosaic.
The software cannot be used to remove mosaics generated by other methods.
The coded photo does not contain password information, and the software does not verify it when decoding. Therefore, overly simple passwords have the possibility of being cracked multiple times.
