The present invention relates to a system and method for providing authenticated augmented reality content, and more particularly, to a system and method for registering and providing augmented reality content of an authenticated user for a target object.

Recently, with the rapid development of 3D image processing technology, virtual environment services using virtual reality (VR) or augmented reality (AR) are provided in various fields such as movies, games, and interiors. Among them, augmented reality is a technology that provides a user with an image without a boundary between the real world and the virtual world by synthesizing and displaying a real image and virtual augmented reality content.

These virtual environment services are used in various fields such as remote medical diagnosis, architectural design, and manufacturing process management. For example, when a user photographs a medical device with a camera, augmented reality content corresponding to the medical device may be combined with an image of the medical device and displayed. Through these virtual environment services, users can properly and appropriately use medical equipment.

In this case, only an authorized manager should be able to provide augmented reality content to an object to be professionally guided, such as medical equipment.
