| description | A content transmission system transmits content, using a cloud computing system. A recording device records the content to a local storage or a cloud storage. When the local storage is selected as a recording destination, the recording device generates an encryption key, encrypts the content with the key, and generates management information associating the key with an address of the cloud storage. The recording device furthermore determines whether a portable recording medium is connected thereto. If connected, the recording device records the key and the management information to the portable recording medium. The terminal device first reads the key and the management information from the portable recording medium. The terminal device then accesses the cloud storage without performing user authentication, referring to the management information, and downloads the encrypted content from the cloud storage. Furthermore, the terminal device decrypts the content from the encrypted content, using the key. |
