<p>A right management system for disclosing secret information to only a specific data user having a right to receive the disclosure of the secret information only when the data owner meets the data user face to face and confirms the authentication of the data user. The owner possessing the disclosure object data encrypts the data, creates the decryption key for the data, separates it, and sends in advance the data to the disclosure object person to which the data is to be disclosed. When the data is disclosed, the data owner physically faces the terminal of the disclosure object person and sends the decryption key while they are close to each other. The terminal reproduces the decryption key and decrypts the data with the decryption key to disclose the data. With this, the data owner comes in proximity to the disclosure object person having the right to receive the disclosure, and sees the disclosure object person, and confirms the authentication of the disclosure object person.</p> |
