Abstract
An image forgery prevention device and a method thereof using a hash function are proposed, and the device includes a privacy area detection processor configured to detect a privacy area image from an original image, a hash value generation processor configured to use the hash function to generate a hash value of the privacy area image, an obfuscation processor configured to obfuscate the privacy area image, and a verification hash value insertion processor configured to insert a verification hash value corresponding to the hash value into an obfuscated privacy area of the original image in a predetermined encrypted form, so that the image forgery prevention device and the method thereof using the hash function of the present disclosure provides an efficient means for verifying whether a privacy area image is authentic or not by inserting verification hash value information in a metadata form or watermarking form into an obfuscated area of an original image.
