Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an information processing apparatus, an information processing method, and a program capable of securing confidentiality with respect to specific information.SOLUTION: The information processing apparatus encrypts generated data with a common key and stores the generated data in a block connected by a block chain built in a network. Also, a second public key different from the first public key stored in advance is acquired from the block linked by the block chain. Then, the common key is encrypted with the second public key, and the encrypted common key is stored in the block linked by the block chain.SELECTED DRAWING: Figure 6 【課題】特定の情報に対する秘匿性を担保することができる情報処理装置、情報処理方法およびプログラムを提供する。【解決手段】情報処理装置は、ネットワーク内に構築されるブロックチェーンで連結されるブロックに、生成されたデータを共通鍵で暗号化して格納する。また、予め記憶している第１公開鍵とは異なる第２公開鍵を、ブロックチェーンで連結されたブロックから取得する。そして、第２公開鍵で共通鍵を暗号化し、暗号化した共通鍵をブロックチェーンで連結されるブロックに格納する。【選択図】図６
