데이터 활용, 무엇을 어떻게 할 것인가?

In so-called data economy era, huge amount of data are generated in multiple ways in both public and private sectors. But traditionally and currently as well, personal data have been the target of protection against illegal data disclosure and fraud, which drives more attention to ‘protection’ rather than ‘utilization’ especially in Korea. However concern for data protection does not justify accumulating-but-not-utilizing personal data. Data should not be generated and existent in order to be protected. They have value when they are used, not when they are accumulated without doing anything with them. After demonstrating the necessity of data usage, this paper analyzes theoretical and practical conflicts happening between data usage and data protection, and suggests policy recommendations with balanced perspectives between those two issues. For doing this, the study presents types of personal data with multiple criteria and suggests characteristics and cases of data usages in each category of the typology. Cases show what kind of data can be used?, what are sectors and impacts of data-usage?, and what are significant issues raised in the process of data-usage.
