Abstract: Systems, methods, and storage media for providing a content recommendation service based on user viewed content without access to the user viewed content are disclosed. Exemplary implementations may: make an executable translation component available to a content provider; receive, from the content provider, multiple sets of content information; store the sets of content information in a database; receive a request from the content provider to provide a content recommendation; receive a content ID for content viewed by a user; query the database with a query based on embedding data corresponding to the content ID for content viewed by a user; process the query to obtain additional content IDs which correspond to additional content that is related to the content viewed by the user; and send the additional content IDs to the content provider.
