I am going to include some pictures of patients in my manuscript, which will be submitted to a scientific journal for peer review. In order to keep the subjects’ identity and following the data protection act, I need to hide their faces.
My question is to know whether to put a black rectangle over their faces, especially their eyes or pixelising their faces. I have been told that putting a black rectangle is not recommended for this purpose, but I have never been told the reason.
Could somebody please let me know first that:
- Which method is better?
- Is that the case that blackening the face is not recommended. If true, why?
