Abstract : Security Techniques are required due to the illegal access of data without permission. Due to accessof illegal data issue of Intellectual property right information arises. Therefore it has become necessity to provide secured and robust technology to protect data. As we know that the data can be transmitted through medium like wired network or wireless network. Data can be transmitted in text format or as Image or as song file or video files etc.To protect the data from illegal users and provide Intellectual Property Right (IPR),We have to used various security techniques such as encryption & decryption, steganography, Digital Watermarking etc. In this paper, we are going to discuss “Security of Still Image by Using Digital Watermarking Technique by Using Discrete Cosine Transform and Spread Spectrum”
