Drm-based content encryption/decryption systems and encryption/decryption methods

Abstract

The present disclosure relates to methods and systems based on digital rights management (DRM), and more particularly to DRM-based encryption/decryption methods and encryption/decryption systems that can encrypt/decrypt content using metadata. The DRM-based content encryption system of the present disclosure may include a content provider that encrypts content to be encrypted based on encryption information received from a DRM server to generate encrypted content, a DRM server that provides said encryption information to the content provider based on a request from the content provider, a decryption server that provides decryption information corresponding to the encryption information to the user terminal based on a request from the user terminal, and the user terminal that decrypts the encrypted content based on the decryption information received from the DRM server to generate decrypted content.

Dependencies are inferred from the claim text.
