Systems, methods, and computer storage media having computer-executable instructions embodied thereon that maintain privacy during user profiling are provided. A profiling service receives, from a first device, rules for profiling a user. The rules were encrypted using a private key. The profiling service also receives, from a second device, user data. The user data was encrypted using a public key communicated to the second device by the first device. The profiling service then matches the encrypted rules with the encrypted user data, and based on the matching, generates a profile for the user. In embodiments, such a user profile can be utilized to deliver personalized digital content to a user.

Maintaining privacy during user profiling

Methods, systems, and computer-readable media for facilitating personalization of web content is provided, while protecting the privacy of the user data utilized to personalize the user's experience. A privacy vault may collect user data including user activity data, demographic data, and user interests submitted by a user. In one embodiment, the privacy vault operates on a user client device. The privacy vault sends the user data to a community vault that collects user data from multiple users. The community vault generates segment rules that whether a user belongs to a user segment, which expresses a user's interest. The segment rules are then communicated back to the privacy vault, which assigns one or more user segments to the user based on the user data available to the privacy vault and the segment rules. The privacy vault may communicate user segments to one or more content providers that supply personalized content that is selected based on the user segments provided.
