IMPLEMENTASI WATERMARKING DENGAN METODE DISCRETE COSINE TRANSFORM (DCT) PADA CITRA DIGITAL
CITRA DEWIE YULLINDA (2008) | Skripsi | Teknik Informatika , Teknik Informatika
Bagikan
Ringkasan
Digital data very easy in its use, cheap in duplication and also to save for
used next time. That things finally can be used by negative like ploughing the
digital data to be overspread by someone who unresponsible . A lot of way that
already to do to give the security or protect the the digital data.. Finnaly there is a
concept to use watermarking for overcome the problem. Watermarking is one of
technique of data hiding, so the existence is not detected by the other.
Watermarking technique protect the digital media with the planted certain data
permanently in pertinent media. Watermarking can be used as information about
digital data itself or the other information which considered necessary to be
inculcated into the digital image.
There are assorted of technique watermarking, use the transformasi,
either in domain spasial and also frequency for the document in the form of
digital image. In this project will be realized scheme of software watermarking by
applying method of transformasi DCT or Discrete Cosine Transform at domain
frequency at digital image
