Abstract
Methods, systems, and apparatus, including an apparatus for preventing data leakage by controlling the availability of user data. In one aspect, a system includes a frontend server that receives digital component requests that each specify a user identifier for a user to which digital component will be provided and provides digital components. A data availability control server receives data specifying a user identifier for a user and controls availability of activity data to digital component providers by identifying, for a given digital component provider, data sets that include a user identifier for the user and are data sets from which the digital component provider is eligible to receive data. The data availability control server selects, from a specified number of the identified data sets, the activity data of the user included in the specified number of identified data sets and provides the selected data to the given digital component provider.
