Digital Watermarking Techniques in Spatial and Frequency Domain
It provides an overview of existing methods for content protection and authentication, which is incremental and primarily useful for researchers or practitioners in digital security.
The paper reviews various digital watermarking techniques in spatial and frequency domains for embedding information into multimedia data with minimal distortion, but does not present new results or concrete numbers.
Digital watermarking is the act of hiding information in multimedia data, for the purposes of content protection or authentication. In ordinary digital watermarking, the secret information is embedded into the multimedia data (cover data) with minimum distortion of the cover data. Due to these watermarking techniques the watermark image is almost negligible visible. In this paper we will discuss about various techniques of Digital Watermarking techniques in spatial and frequency domains
