PRIVACY CONTROLS FOR SHARING EMBEDDINGS FOR SEARCHING AND INDEXING MEDIA CONTENT

摘要

This document describes techniques and systems that enable privacy controls for sharing embeddings for searching and indexing media content. A set of images of a user's face are obtained and a machine-learned model (122) is applied to the set of images to generate a user-specific dataset (124) of face embeddings for the user. Media content stored in a media storage (116, 136) is indexed by applying the machine-learned model (122) to the media content to provide indexed media information (118) identifying one or more faces shown in the media content. Access to the indexed media information (118) by another user querying the media content for images or videos depicting the user is controlled based on a digital key (112) shared by the user with the other user, where the digital key (112) is associated with the user-specific dataset (124) and the user-specific dataset (124) is usable to identify the images or videos depicting the user.
