Abstract: The determination of a unique user is discussed in response to receiving a dataset comprising multiple user identifiers (IDs). In some cases the user IDs may be of a different type. User IDs may be compared directly to determine whether they correspond to a unique user. Network transactions and attributes associated with those network transactions may be compared to determine a probability of whether two user IDs correspond to a unique user. Network transactions and attributes associated with those network transactions may also be compared to determine that two user IDs do not correspond to a unique user.

Abstract: Relationships between a plurality of mobile devices are automatically determined. For each mobile device in the plurality of mobile devices, characteristics of a user of the mobile device are determined. Based on the characteristics of the users of the mobile devices, a first role of a first user of a first mobile device is determined. Based on the characteristics of the users of the mobile devices, a second role of a second user of a second mobile device is determined. Based on the first role and the second role, a relationship between the first user and the second user is determined. A determination is made that a relationship between the first mobile device and the second mobile device is equal to the relationship between the first user and the second user.
