What Can I Do About A Nigerian Person Threatening to Expose Photos on the Internet?
Blackmail is the crime of threatening to reveal embarrassing, disgraceful or damaging information about a person to the public, family, spouse or associates unless money is paid to purchase silence. It is a form of extortion. Because the information is usually substantially true, it is not revealing the information that is criminal, but demanding money to withhold it. Blackmail has been defined in the broad sense to mean "compelling someone to act against their will or gaining or attempting to gain something of value." Courts vary on interpreting what "something of value" includes, but it is not necessarily a money payment in all cases. A criminal complaint is typically filed with the local police department or prosecutor's office.
A person obtains property by extortion when he compels or induces another person to deliver such property to himself or to a third person by means of instilling in him a fear that, if the property is not so delivered, the actor or another will:
(i) Cause physical injury to some person in the future; or
(ii) Cause damage to property; or
(iii) Engage in other conduct constituting a crime; or
(iv) Accuse some person of a crime or cause criminal charges to be instituted against him; or
(v) Expose a secret or publicize an asserted fact, whether true or false, tending to subject some person to hatred, contempt or ridicule; or
(vi) Cause a strike, boycott or other collective labor group action injurious to some person's business; except that such a threat shall not be deemed extortion when the property is demanded or received for the benefit of the group in whose interest the actor purports to act; or
(vii) Testify or provide information or withhold testimony or information with respect to another's legal claim or defense; or
(viii) Use or abuse his position as a public servant by performing some act within or related to his official duties, or by failing or refusing to perform an official duty, in such manner as to affect some person adversely; or
(ix) Perform any other act which would not in itself materially benefit the actor but which is calculated to harm another person materially with respect to his health, safety, business, calling, career, financial condition, reputation or personal relationships.
I am unable to determine the ownership of the pictures Copyright infringement is the violation of any exclusive right held by the copyright owner. The general rule is that the author - here, the photographer -- is the owner of the copyright.
Invasion of privacy involves making something public in which a person has a reasonable expectation of privacy. It's not enough to argue that the photos were private; you must be able to prove that you and the photographer had an agreement never to share them with the outside world.
