Regardless of industry, companies are concerned about the proper handling and use of personal information. Companies operating globally need to continuously adapt their services to the relevant laws of their various industries, which takes up a vast amount of resources. For example, Korean laws regarding data privacy are continuously updated such that companies doing business in Korea are forced to continuously and actively remain compliant. Additionally, with the revision of the so-called “Big 3 Data Laws”, the distribution and utilization of all data, including personal data, are expected to accelerate. With the inevitable evolution and expansion of the big data industry, apprehensions about potential personal information infringement are also expected to increase. To successfully enter the big data industry in Korea, companies will require a thorough legal review of their systems and processes in place to prevent and address personal information infringement.
