Now-a-days internet play a big role and used for carrying information from one place to another. And this information may be images, audio, and also video. Strikes on the digital data are very simple and easily monitored in the internet. And in this way watermarking process is used for the purpose of authentication. And in the grayscale image watermarking process is used for the process of embedding and detection. Wavelet multi-resolution is also used in the watermarking process. Wavelet means the small signal which work simultaneously in time and frequency. During the embedding process, spread spectrum technique is used. And the influence of watermark is adjusted according the cover image or the original form of image. The DCT (Discrete Cosine Transform) and DWT (Discrete Wavelet Transform) method are used. And this method is not more resistant against the different types of strikes, different forms of noise and JPEG compression because non-blind watermarking algorithm is used in that case. In this paper we purposed a new method and technique which is more resistive against the different types of attacks, different types of noises and JPEG compression. We have use DWPT (Discrete Wavelet Packet Transform) and also the blind detection technique. The meaning of Blind detection is that, we cannot use the original or the cover image information during its extraction process. And for the point of view of security we also have to implant the confidential key. And this confidential key is prepared by using the different kinds of image or the text image. And this method is basically used for the purpose of copyright verification
