===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.{{sfn|Solove|2010|pp=104–05}} Actions in this category which can lessen privacy include the following:{{sfn|Solove|2010|pp=104–05}}

* [[data aggregation]], which is connecting many related but unconnected pieces of information{{sfn|Solove|2010|pp=104–05}}
* 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{{sfn|Solove|2010|pp=104–05}}
* 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{{sfn|Solove|2010|pp=104–05}}
* secondary use, which is when people agree to share their data for a certain purpose, but then the data is used in ways without the data donors' [[informed consent]]{{sfn|Solove|2010|pp=104–05}}
* exclusion is the use of a person's data without any attempt to give the person an opportunity to manage the data or participate in its usage{{sfn|Solove|2010|pp=104–05}}
