A comparative study on countermeasures leakage of personal information in new mobile phone registration and change in Korea

Abstract

Background/Objectives: If you cancel or change your mobile phone number in Korea, the existing number will be given to other new subscribers. As a result, the personal information of users of existing number is exposed. Methods/Statistical analysis: As the smartphone convenience service becomes linked to the mobile phone number, the existing convenience service is notified or announced to the existing number even if the user changes, thereby disclosing the personal information of the existing user to the new user. Findings: This is because the 010 number integration policy and personal information identification are used as mobile phone numbers. Accordingly, in order to prevent exposure of personal information, measures such as securing a new 010 number, strengthening the personal identification scheme in the service of the mobile phone convenience, and deleting the personal information of the associated service when changing the mobile phone number are necessary. Improvements/Applications: If you resolve the cause of personal information disclosure, you will not be exposed to the personal information of existing users through the change and termination of mobile phone service number.
