Abstract

The method for content management of the present invention comprises the steps of: a backend device receiving content and content information from a seller device; the backend device checking whether the content is a previously registered content; if the backend device is not a previously registered content, the backend device checking whether the content information contains all information necessary for creating content metadata; if all information is contained, the backend device converting the content information into content metadata; the backend device uploading the content and the content metadata to IPFS; and the backend device returning a content identifier corresponding to the content to the seller device.
