<p>A developer/requestor may select a subset of users for a promotion by querying a database; however, the developer may not be provided with specific details about each user (e.g., purchase history, browsing history, etc.). The system returns a response to the query that obfuscates a user's data while simultaneously providing the developer with a response to indicate to the developer whether or not a user or group of users is promotion eligible based on the developer's criteria. The developer may dispatch a promotion to the one or more users determined to be promotion eligible.</p> |
