Brief the basic demands of watermarkingframework

The basic demands of a watermarking framework can be broken down into the following steps:

1. Robustness: The watermark should be able to resist various attacks such as compression, cropping, filtering, etc. It should remain intact even after various image processing operations.

2. Imperceptibility: The watermark should be invisible or inaudible so that it does not affect the quality of the original content. The user should not be able to detect the presence of the watermark.

3. Security: The watermarking scheme should be secure enough to prevent unauthorized detection, removal or alteration of the watermark. The watermark should only be detectable by authorized parties.

4. Capacity: The watermarking scheme should be able to embed enough information in the content without affecting its quality. The capacity of the watermark depends on the size and nature of the content.

5. Efficiency: The watermarking scheme should be computationally efficient. It should not require a lot of computational resources or time to embed or detect the watermark.

6. Blind or Non-Blind: In a blind watermarking scheme, the original content is not required to detect the watermark. In a non-blind scheme, the original content is required. The choice between blind and non-blind watermarking depends on the specific application.

7. False Positive and False Negative Rates: The watermarking scheme should have low false positive and false negative rates. A false positive occurs when the watermark is detected in content where it was not embedded. A false negative occurs when the watermark is not detected in content where it was embedded.
