在智慧聯網的時代，資料透過諸如手機、平板等各式聯網裝置迅速累積，不僅改變人們的 生活，對許多既有的管制架構也帶來衝擊。2014 年的 4 月和 5 月，歐洲法院公布了兩項對資料 保護有甚大影響的兩項判決，其中一項宣布 2006 年的資料保存指令無效，另一項則確立了搜尋 引擎的營運者就個人資料保護應盡的義務。本文嘗試梳理這兩項判決，以期作為我國未來相關 政策推動或法院未來判決方向之參考。

In the era of Internet of Things, data is accumulated at an unprecedented speed through connected devices such as mobile phones and tablets. Not only have lives of people changed due to this phenomenon, so are impacts brought upon various regulatory frameworks. In April and May, 2014, the Court of Justice of European Union announced two rulings that have tremendous implications on data protection. One of them annulled the 2006 Data Retention Directive (Directive 2006/24/EC), and the other spelt out the obligation of an operator of search engine services in the respect of data protection. This article aims for providing reference for related policy-making and perhaps as well as rulings of local courts in the future by introduction of the abovementioned two rulings.
