The correct answer is Confidentiality and anonymity of participants is especially important.
Confidentiality means you know who the participants are but withhold their identities from your study report, whereas anonymity means you don't know who they are. Both are significant moral issues. The major distinction between secrecy and anonymity is that, in the former, only the researcher is aware of the participants' identities, whereas, in the latter, not even the researcher is. Because they safeguard the privacy of persons who willingly consent to participate in research, anonymity and secrecy are crucial. To protect the privacy of their subjects' identities, researchers use a variety of techniques. They protect their records first and foremost by using password-protected files, encryption when transmitting data over the internet, and even the more traditional closed doors and drawers.
