dhdd.zip - contains executable DHDD programs and
examples.
1) Download dhdd.zip and uncompress it. The following files will be
extracted:
data-in.vet - A
sequence of bits to be embedded
ink-dhdd.exe - DHDD program
for inkjet printer
ink-ori.pbm - A
binary document
ink-ps.jpg -
ink-ori.pbm after being watermarked, printed and scanned.
ink-run.bat - The
batch file that executes inkjet test
las-dhdd.exe - DHDD program
for laserjet printer
las-ori.pbm - A
binary document
las-ps.jpg -
las-ori.pbm after being watermarked, printed and scanned.
las-run.bat - The
batch file that executes laserjet test
2) Execute ink-run. It will execute the following operations:
:: Embeds the bits specified in
data-in.vet in image ink-ori.pbm, generating ink-wmk.pbm
ink-dhdd s4d ink-ori.pbm
data-in.vet ink-wmk.pbm 9 12 3 2
:: Extracts the hidden bits from
ink-wmk.pbm, writing them in ink-wmk.vet
ink-dhdd v4d ink-wmk.pbm
ink-wmk.vet
:: ink-ps.jpg was obtained
printing and scanning ink-wmk.pbm
:: Extracts the hidden bits from
ink-ps.jpg, writing them in ink-ps.vet
ink-dhdd v4d ink-ps.jpg ink-ps.vet
Note that the extracted bits and the inserted ones are the same.
3) Execute las-run. It will execute the following operations:
:: Embeds the bits specified in
data-in.vet in image las-ori.pbm, generating las-wmk.pbm
las-dhdd s4d las-ori.pbm
data-in.vet las-wmk.pbm 9 12 3 2
:: Extracts the hidden bits from
las-wmk.pbm, writing them in las-wmk.vet
las-dhdd v4d las-wmk.pbm
las-wmk.vet
:: las-ps.jpg was obtained
printing and scanning las-wmk.pbm
:: Extracts the hidden bits from
las-ps.jpg, writing them in las-ps.vet
las-dhdd v4d las-ps.jpg las-ps.vet
Note that the extracted bits and the inserted ones are the same.
