There may be other law and policy considerations you'll need to make about the third-party content you include in your dissertation. These would include such questions related to human subject research methodology, issues of indigenous knowledge, and more. Likely you have conferred with your dissertation advisors about research and publishing ethics, which are beyond the scope of this guide.
What this guide does address, though, are permissions questions about third party content that may, at first, seem like copyright concerns, but actually implicate other legal doctrines. Step 3 helps you identify these potential non-copyright legal questions that can impact your permission-seeking and publication process.
⇒ Rights of Privacy
Copyrights protect copyright holders' property rights in their works, while privacy rights protect the interests of people who are the subjects of those works.
Privacy rights most often arise if you are seeking to use third party content like correspondence, diaries, and images that contain personal information about or pictures of particular people.
In addition to a number of federal statutes that protect against disclosure of various types of personal information (e.g. FERPA (student information) and HIPAA (health information)), there are also state laws governing privacy.
State privacy laws make intrusions of privacy a tort (i.e. a wrongful act). The four typical types of intrusions that state laws protect against are: intrusion upon seclusion; public disclosure of private facts; painting someone in a false light; appropriation of name or likeness.
How Should You Address Privacy Concerns?
You may not need to dig too deep. There are important limitations on privacy rights in the context of your scholarship.
First, privacy rights expire at death--meaning, you can't be liable for disclosing private facts about a person no longer living.
Second, there are typically two other important defenses to claims for invasion of privacy: newsworthiness, and permission. If the material you wish to include reveals private facts that are "newsworthy" (of public interest or concern--which your dissertation scholarship may be), or the person who is the subject of the information has given you permission to publish (which you may have obtained), then an invasion of privacy claim should not be sustainable. For more on newsworthiness and permission exceptions, exploring the Digital Media Law Project out of Harvard University's Berkman Klein Center should prove helpful. It is no longer being updated, but contains very useful explanations.
⇒ Rights of Publicity
Publicity rights also are tied to the subject (i.e. person) who is depicted in the work.
As with privacy torts, there is no generally-applicable rule across U.S. jurisdictions. If a state recognizes the "right of publicity," such laws typically prevent unauthorized commercial use of an individual’s name, likeness, or personal attributes. Publicity rights thus provide individuals with rights to control the commercial use of their identity, and sue for damages.
How Should You Address Publicity Rights?
Unlike privacy rights, publicity rights usually survive an individual's death, such that a person's estate may enforce them even if the person is no longer alive. Further, remember that the right of publicity is a protection independent from copyright. Thus, even if photographs of a famous historical figure may be in the public domain, that person's estate may still choose to enforce publicity rights against unauthorized commercial appropriation of his/her likeness.
But remember the important foundation of and thus limitation on publicity rights: They are typically intended to prevent unauthorized commercial use of one's identity. Thus, they are often inapplicable unless you collect royalties or publish a book.
