is neither completely paradoxical nor completely logical, and the consistency between concerns and behavior depends on users, situations, or contexts. Actions which reduce privacy As with other conceptions of privacy, there are various ways to discuss what kinds of processes or actions remove, challenge, lessen, or attack privacy. In 1960 legal scholar William Prosser created the following list of activities which can be remedied with privacy protection: Intrusion into a person's private space, own affairs, or wish for solitude Public disclosure of personal information about a person which could be embarrassing for them to have revealed Promoting access to information about a person which could lead the public to have incorrect beliefs about them Encroaching someone's personality rights, and using their likeness to advance interests which are not their own From 2004 to 2008, building from this and other historical precedents, Daniel J. Solove presented another classification of actions which are harmful to privacy, including collection of information which is already somewhat public, processing of information, sharing information, and invading personal space to get private information. Collecting information In the context of harming privacy, information collection means gathering whatever information can be obtained by doing something to obtain it. Examples include surveillance and interrogation. Another example is how consumers and marketers also collect information in the business context through facial recognition which has recently caused a concern for things such as privacy. There is currently research being done related to this topic. Aggregating information It can happen that privacy is not harmed when information is available, but that the harm can come when that information is collected as a set, then processed together in such a way that the collective reporting of pieces of information encroaches on privacy. Actions in this category which can lessen privacy include the following: data aggregation, which is connecting many related but unconnected pieces of information identification, which can mean breaking the de-identification of items of data by putting it through a de-anonymization process, thus making facts which were intended to not name particular people to become associated with those people insecurity, such as lack of data security, which includes when an organization is supposed to be responsible for protecting data instead suffers a data breach which harms the people whose data it held secondary use, which is when people agree to share their data for a certain purpose, but then the data is used
