Abstract: Systems, methods and non-transitory computer readable media for ownership determination in privacy firewalls are provided. A request of a user to perform an action for creating a new data collection using source data collections may be received. In response to the user not having permission to view at least part of at least one of the source data collections and the user not being an owner of the at least one of the source data collections, it may be determined that the user is not an owner of the new data collection, and in response to the user being at least an owner of the data collection or having permission to view the entire data collection for all source data collections, it may be determined that the user is an owner of the new data collection.

Abstract: Systems, methods and non-transitory computer readable media for controlling access in privacy firewalls are provided. A request to access a content of an element may be received, the content of the element may include a first portion and a second portion, the first portion may include identifiable information and the second portion may include no identifiable information.

In response to a second value of the confidence level, providing the particular information to the first entity and forgoing providing the particular information to the second entity.

Abstract: Systems and method for selectively providing information about medical data are provided. A first statistical query based on an input from a first user may be received. A first estimated property based on the first statistical query may be provided to the first user. A second statistical query based on an input from a second user may be received. A first group of users that includes the first user may be selected. It may be determined whether the first group of users includes the second user. In response to a determination that the first group of users does not include the second user, a second estimated property may be provided to the second user, and in response to a determination that the first group of users includes the second user, providing the second estimated property may be forwent.

Abstract: Systems, methods and non-transitory computer readable media for hybrid differential privacy are provided. Queries associated with medical data may be received. The medical data may be accessed to determine a possible response to queries. Privacy loss levels associated with the possible responses may be determined. Confidence levels for the determinations of the privacy loss levels may be determined. Based on the privacy loss level and the confidence level corresponding to a particular possible response, it may be determine whether to provide the particular possible response, to avoid providing the particular possible response, or to involve manual review in a determination of whether to provide or to avoid providing the particular possible response.
