Blur Resistant Image Authentication Method with Pixel-wise Tamper Localization
Romualdas Baušys, Artūras Kriukovas · Elektronika ir Elektrotechnika · 2009
A new digital signature based method for image authentication and pixel-wise tamper localization is proposed. The proposed method is resistant to image content preserving enhancement operations such as blurring or sharpening. Authentication function is implemented separately from tamper localization both to increase processing speed and to disable algorithmic oracle attack.
