Worldcoin's Iris Scan: Is it Really Safe?

Worldcoin's free coin distribution through iris recognition has recently become a hot topic in South Korea. However, there's a heated debate surrounding the value and safety of the coins obtained in exchange for providing iris data, which is sensitive personal biometric information. Let's delve into whether it's truly safe and if there are any potential issues.

Worldcoin: What is it and how does it work?

Worldcoin is a cryptocurrency created by OpenAI, founded by Sam Altman. It utilizes iris recognition as a means of identity verification to differentiate between AI and humans online.

Through iris recognition, users can create a World ID and receive Worldcoin. They can receive 3 Worldcoins every two weeks for a total of 76 Worldcoins over a year.

Currently, there are 10 cafes and restaurants in South Korea equipped with iris authentication devices. Due to its recent price surge, it is valued at approximately 800,000 won.

Worldcoin Issues

1. Controversy over Personal Information Trading

Iris data is unique and cannot be modified, and its trading is illegal under the Personal Information Protection Act. Worldcoin has sparked controversy surrounding the trading of personal information by offering cryptocurrency in exchange for iris data.

2. Lack of Transparency in Information Use and Handling

There's a lack of clear explanation regarding where and how iris data is utilized. According to the Personal Information Protection Act in South Korea, the purpose, duration, and method of collecting personal information, as well as the possibility of international transfer, must be disclosed beforehand. However, Worldcoin has failed to provide adequate information on these aspects.

3. Risk of Data Transfer to Overseas Servers

Worldcoin plans to store the collected iris data on overseas servers. This raises concerns about potential data leaks and misuse, making it difficult to protect the information under domestic laws.

4. Bans and Investigations Abroad

Worldcoin issuance and trading are prohibited in the United States, and other countries, including the United Kingdom, France, and Germany, are currently investigating its legality.

5. Unclear Purpose and Usage of Information

Worldcoin does not clearly disclose the purpose and usage of the collected personal information. There are no clear terms regarding regular information usage updates, data disposal deadlines, etc., to protect personal information.

Expert Warnings

Professor Myung-joo Kim, Seoul Women's University, Department of Information Security: Iris data is unique personal information, and trading it is illegal.

Jin-hong Choi, YK Lawyer: It is illegal to use data for purposes other than those previously disclosed. Explanation of overseas server transfer is required.

Professor Seok-jin Hwang, Dongguk University Graduate School of International Information Security: The purpose of information utilization must be clarified, and collection and disposal deadlines must be established.

In conclusion, Worldcoin's iris authentication presents several challenges in terms of personal information protection, and it's crucial to approach it cautiously. Instead of blindly accepting free coins, we encourage everyone to reconsider the importance of personal information.
