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.
