It refers to personal information processed by deleting part of the descriptions contained therein (including replacing them with other descriptions using methods that do not have the regularity to restore the original descriptions), so that specific individuals cannot be identified unless cross-referenced with other information. In other words, the data has been processed so that individuals cannot be identified without combining it with additional information (deletion information, etc.), and the decisive difference from anonymized information is that technically it CAN be reverted to the original.\n::\n\n::heading\n2020[年]{ねん:year:N5}[改正]{かいせい:amendment:N2}の[背景]{はいけい:background:N3}\n\n#en\nBackground of the 2020 amendment\n::\n\n::para\nこの[制度]{せいど:system:N3}は、2020[年]{ねん:year:N5}（[令和]{れいわ:Reiwa:N2}2[年]{ねん:year:N5}）の[個人]{こじん:individual:N2}[情報]{じょうほう:information:N3}[保護]{ほご:protection:N1}[法]{ほう:law:N3}[改正]{かいせい:amendment:N2}により[新設]{しんせつ:newly established:N2}されました。[改正]{かいせい:amendment:N2}[前]{まえ:before:N5}は、[事業者]{じぎょうしゃ:business operator:N4}が[社内]{しゃない:in-house:N3}でデータ[分析]{ぶんせき:analysis:N1}を[行う]{おこなう:carry out:N5}[場合]{ばあい:case:N3}でも、[個人]{こじん:individual:N2}[情報]{じょうほう:information:N3}として[厳格]{げんかく:strict:N1}な[規制]{きせい:regulation:N3}を[受ける]{うける:receive:N3}か、[匿名]{とくめい:anonymous:N1}[加工]{かこう:processing:N3}[情報]{じょうほう:information:N3}として[不可逆]{ふかぎゃく:irreversible:N2}な[加工]{かこう:processing:N3}を[施す]{ほどこす:apply:N1}[必要]{ひつよう:necessary:N3}がありました。[仮名]{かめい:pseudonym:N1}[加工]{かこう:processing:N3}[情報]{じょうほう:information:N3}は、その[中間]{ちゅうかん:middle:N5}に[位置]{いち:position:N3}する[制度]{せいど:system:N3}として[設計]{せっけい:design:N2}されました。[個人]{こじん:individual:N2}[情報]{じょうほう:information:N3}（[厳格]{げんかく:strict:N1}）と[匿名]{とくめい:anonymous:N1}[加工]{かこう:processing:N3}[情報]{じょうほう:information:N3}（[作成]{さくせい:creation:N3}[困難]{こんなん:difficult:N3}）の[間]{あいだ:between:N5}を[埋める]{うめる:fill:N2}ことで、[社内]{しゃない:in-house:N3}での[安全]{あんぜん:safe:N3}なデータ[利活用]{りかつよう:utilization:N3}を[促進]{そくしん:promote:N1}する[狙い]{ねらい:aim:N2}があります。\n\n#en\nThis system was newly established by the 2020 (Reiwa 2) amendment to the Act on the Protection of Personal Information. Before the amendment, when business operators performed in-house data analysis, they either had to comply with strict regulations as personal information, or apply irreversible processing to create anonymized information. Pseudonymized information was designed as a system positioned between these two.
