Abstract
Data privacy is provided in a computer network using a security inference control processor of a network device in the computer network which receives a query from a user device through a network interface circuit. In response to the query, a query result data set is generated based on information in a database stored in a non-volatile data storage device. Personally Identifiable Information (PII) exposure risk associated with the query result data set is determined based on an evaluation of combining the query result data set with an exposure storage log that includes result data sets from past queries associated with the user. Based on the PII exposure risk, the query result data set is provided to the user, so as to refrain from providing the query result data set if the PII exposure risk is greater than a risk threshold. Related methods, devices, and computer program products are provided.
