Systems, methods, and storage media for providing a secured content recommendation service based on user viewed content

A method for providing a content recommendation service based on user viewed content without access to the user viewed content, the method comprising:

• making an executable translation component available to a content provider, the translation component including a component for translating source text to embedding vectors and obfuscating the embedding vectors to create embedding data corresponding to the source text, wherein the embedding data is indicative of the subject matter of the source text;
• receiving, from the content provider, multiple sets of content information, each set of content information including embedding data and a content ID corresponding content, the embedding data being created by processing content to create source text and processing the source text by the executable translation component to create the embedding data;
• storing the sets of content information in a database;
• receiving a request from the content provider to provide a content recommendation;
• receiving a content ID for content viewed by a user, the content being viewed by the user through a service provided by the content provider;
• querying the database with a query based on embedding data corresponding to the content ID for content viewed by a user;
• processing the query to obtain additional content IDs which correspond to additional content that is related to the content viewed by the user;
• sending the additional content IDs to the content provider, wherein the content provider can ascertain the additional content and present the related content to the user.

A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method for providing a content recommendation service based on user viewed content without access to the user viewed content, the method comprising:

• making an executable translation component available to a content provider, the translation component including a component for translating source text to embedding vectors and obfuscating the embedding vectors to create embedding data corresponding to the source text, wherein the embedding data is indicative of the subject matter of the source text;
• receiving, from the content provider, multiple sets of content information, each set of content information including embedding data and a content ID corresponding content, the embedding data being created by processing content to create source text and processing the source text by the executable translation component to create the embedding data;
• storing the sets of content information in a database;
• receiving a request from the content provider to provide a content recommendation;
• receiving a content ID for content viewed by a user, the content being viewed by the user through a service provided by the content provider;
• querying the database with a query based on embedding data corresponding to the content ID for content viewed by a user;
• processing the query to obtain additional content IDs which correspond to additional content that is related to the content viewed by the user;
• sending the additional content IDs to the content provider, wherein the content provider can ascertain the additional content and present the related content to the user.
