Abstract
~ JPEG compression is a wide!v ased compres,sion standard for still image.7. We pre.sent a rohast digital image waterinurking algorithm that i s compatible with U baseline ./PEG coinprexsion standard. The DCT c0efficient.s hi an 8x8 block have a parent-child srriicture ~~~hic l z s similar to tl7at of wavelet transform. We e.rp1oit this propery IO cwhed a watermark with maximuin strength and least perceptihilih,. The watermark detection is per?&"d without wferring to the original image. Simtilation results .shaw thut the prapmed algorithm is robust agoinst iwious sigi7ul pmce.ssing /echnique.s and JPEG coding. Transform) Index Terms -Digital Watermarking, DCT (Discrete Cosine
