Danggeun Upgrades Secondhand Fraud Prevention System with AI Agents

## Daangn Sets Out to Eradicate Used Transaction Fraud with the Introduction of AI Guardian! Daangn, a local life community platform, has declared war on used transaction fraud by putting artificial intelligence (AI) technology at the forefront. Having made creating an environment where users can trade with peace of mind its top priority, Daangn is introducing an innovative AI-based system and has set out to build an even stronger safety net. The newly introduced AI agent extensively analyzes a wide range of information, including user posts, real-time chat content, neighborhood verification information, and even mobile device information, to precisely detect fraud risk patterns. This smart AI guardian, upon detecting suspicious activity, immediately assesses the risk level and sends a warning signal to professional monitoring personnel. Thanks to this, even potential fraud attempts that were easily missed by existing systems can now be identified early and proactively addressed. This is considered a significant advancement that raises the paradigm of fraud prevention by a step. Chatroom safety features have also been significantly strengthened. Now, bank account numbers or phone numbers that have been previously abused for fraud are automatically deleted as soon as they are shared in the chat window. Furthermore, attempts to bypass detection through clever number conversion or writing them in Korean are also thoroughly blocked, and a strong warning notification indicating that the information is risky is displayed to the other party, prioritizing user protection. A system to prevent account rental fraud has also been added. If a user logs into a Daangn account from a new device, an immediate notification is sent to the user via text message, AlimTalk, and email. This aims to prevent illegal activities by clearly warning that account rental can be subject to legal penalties. A Daangn official stated, "Creating an environment where users can trade with peace of mind is our top priority," and emphasized, "We will actively utilize advanced technologies, including AI, to eradicate fraud attempts and build a safer, more trustworthy platform." Furthermore, they expressed a firm commitment, stating, "Fraud is a clear criminal act, and Daangn will respond strongly to any fraud attempts in accordance with a zero-tolerance policy." In addition to this, Daangn already operates various safety measures such as sending warning messages upon requests for advance payment, blocking phishing site URLs, and Daangn Pay's secure payment and compensation system, making every effort to protect users. This enhancement of the AI-based system is an extension of these efforts and demonstrates Daangn's continuous commitment to providing an even more seamless security environment.
