Abstract To enable both preventing an alteration of second software to be used for recovering first software, and performing secure update of the second software.SOLUTION: Provided is an information processing device which stores first software into a first storage medium accessible by a CPU and an embedded controller, and stores second software used for recovering the first software into a second storage medium accessible only by the embedded controller, including: first update means for, in accordance with a comparison result between version information of the first software and version information of the second software, updating the second software using the first software; alteration detection means for detecting presence/absence of an alteration in the first software; and recovery means for, when the alteration detection means detects the presence of the alteration in the first software, recovering the first software using the second software.SELECTED DRAWING: Figure 5 【課題】第1のソフトウェアの復旧に用いる第2のソフトウェアの改ざん防止と、第2のソフトウェアのセキュアなアップデートを両立できるようにする。【解決手段】情報処理装置は、CPUおよび組み込みコントローラがアクセス可能な第1の保存媒体に第1のソフトウェアを保存し、組み込みコントローラのみがアクセス可能な第2の保存媒体に第1のソフトウェアの復旧に用いる第2のソフトウェアを保存する情報処理装置であって、第1のソフトウェアのバージョン情報と第2のソフトウェアのバージョン情報との比較結果に応じて、第1のソフトウェアで第2のソフトウェアをアップデートする第1のアップデート手段と、第1のソフトウェアの改ざんの有無を検知する改ざん検知手段と、改ざん検知手段により第1のソフトウェアの改ざんがあることが検知された場合には、第2のソフトウェアで第1のソフトウェアを復旧する復旧手段とを有する。【選択図】図5
