Abstract

With the current commodity marker´s counterfeits and inferior phenomenon, this paper presents a design of portable instrument for detecting trademark with digital watermark. The hardware structure of this detecting instrument is centering in S3C241 microprocessor, expanding peripheral interface, such as USB, human-computer interaction and so on. Detection software chooses a combination of DCT (Discrete cosine transform) and DWT (Discrete wavelet transform) algorithm as the detecting algorithm of this detecting instrument for distinguishing the authenticity of trademark. The detecting instrument is characterized by high reliability, small size, easy operation and good practicability for application.
