If Internet Companies are Banned from Collecting RRN, Why Not Banks?

K.S. Park argues that, since massive data breaches of internet companies such as Cyworld’s 35 million people’s in 2011 justified the resident registration number collection ban on those companies, banks should be prohibited from collecting RRNs as well in the wake of over 100 million people’s data leaked from Lotte, NH, and KB card companies. He explains that banks collect other identifying data such as birthday, gender, and birth place already and do not need RRNs for identification purposes. Furthermore, RRNs have been collected by too many companies and agencies that they are accessible by so many people that they cannot serve as unique identifiers anyway. Read original here.
