Watermarking has been considered as a technique that provides copyright security, authentication protection to digital data. This technique is an emerging technique in terms of data security. Many techniques and algorithms have been developed for data security. It includes spatial domain or covered domain for data acquisition, in which their various properties are mainly useful for data acquisition, such as robustness, anonymity, and fidelity, etc. Also, it is also seen that covered frequency domain technique gives an excellent result; it is easy to obtain data through this technique from any other domain such as local domain etc., so at present this technique is mostly being used. Data can be strengthened through technology and good digital watermarking can be planned. Nowadays, there are various types of attacks in digital data such as data being stolen unintentionally or intentionally, for which an important plan can be made through this technique, which can include image processing attacks such as compression, frame dropping, theft, Geometric distortion, loss of speaker quality, etc. In this research paper, an in-depth research has been done on various techniques available for watermarking based on frequency domain to find out a secure technique that can withstand any type of attack involving all types of digital content.
