ABSTRACT:
An image processing apparatus prevents reproduction and display of an image file in a viewer of a client PC, etc., by encrypting “fileType” and “version” contained in an Image File Header (IFH), which is file format information, and “tagCount”, “sig_tag0to2”, “type0to2”, “pointer0to2”, and “size0to2”, which are file structure information, of small amounts of data, without encrypting image data (data0, data1, data2) themselves each having a large amount of data in the image file of a Tagged Image File Format (TIFF format).
