How do we put a watermark in the metadata of the image file?
Google "copyright in metadata" (without quotes). A copyright notice, properly stated (see below) can be a part of the metadata per:
http://www.photometadata.org/meta-resources-field-guide-to-metadata#Copyright%20NoticeCopyright Notice [IPTC Core]
The Copyright Notice should include any legal language required to claim intellectual property. It should identify the photograph's current holder(s). If the photographer differs from the copyright holder, enter the photographer's name in the Creator field. Usually, the value for this copyright notice would be the photographer, but if an employee made the image under work-for-hire rules, then list the employing agency or company.
Use the form of notice appropriate to your country.
For the United States, you would typically follow the form of ©<date of first publication> name of copyright owner, as in ©2012 John Doe. Note the word copyright or the abbreviation copr may be used in place of the © symbol. In some foreign countries only the copyright symbol is recognized and the abbreviation is not accepted. Note the copyright symbol must be a full circle with a c inside; using something such as (c), where the parentheses form a partial circle, is not sufficient. For additional protection worldwide, it's best to use of the phrase, all rights reserved following the notice, as in: ©2012 Jane Doe, all rights reserved."
In Europe you use: Copyright {Year} {Copyright owner}, all rights reserved.
In Japan, for maximum protection, the following three items should appear in the copyright field of the IPTC Core: (a) the word, Copyright; (b) year of the first publication; and (c) name of the author. You may also wish to include the phrase all rights reserved.
Notes on usage rights should be provided in the Rights Usage Terms field.
Note: This field is shared with the Copyright Notice field in the Description panel of the Adobe Photoshop File Info field.
U.S. Examples:
Independent Photographer - ©2012 John Doe, all rights reserved
Agency Photographer - ©2012 John Doe / XYZ Agency, all rights reserved
Staff Photographer - ©2008 Big Newspaper, all rights reserved
For international protection, use both the copyright symbol AND the word.
