Core Viewpoint - The app "Neon-Money Talks," which had previously been removed due to serious security vulnerabilities, has quietly reappeared on the Apple Store in the U.S., raising concerns about user privacy and data security in the context of monetizing voice data [1][3]. Group 1: App Overview and Business Model - "Neon-Money Talks" gained popularity by offering users $0.15 for every minute of voice calls, potentially allowing users to earn up to $30 daily, which attracted significant downloads [3]. - The app's business model involves paying users small amounts in exchange for their voice data, which is then sold to AI training companies, exemplifying a "privacy for cash" approach [3][4]. Group 2: Security Concerns - Reports revealed that the app's backend server lacked adequate data access restrictions, exposing users' sensitive information, including call recordings and phone numbers, leading to a complete lack of privacy [3][4]. - Following the exposure of these vulnerabilities, the app's founder announced a server shutdown and the app's removal, claiming a comprehensive security audit was underway [3]. Group 3: Market Trends and Similar Apps - The resurgence of "Neon" is not an isolated incident; numerous similar apps promoting "AI monetization" and "voice monetization" can still be found in the U.S. App Store, indicating a growing trend [4]. - In domestic app stores, similar applications like "Make Money Chatting Talkroom" promise users earnings for chatting, reflecting a consistent business model with "Neon" [4]. Group 4: User Perception and Risks - Despite the risks, the return of "Neon" has garnered a welcoming response from some users, highlighting a dangerous trend of underestimating the value and risks associated with personal data [5]. - Users often overlook the significant disparity between the compensation they receive and the actual value of their data in the AI industry, where a 10-minute call recording can be worth many times more than what users are paid [5]. Group 5: Regulatory and Compliance Issues - Experts have identified three major compliance issues with "voice monetization" apps: inadequate data collection practices, insufficient protection of biometric information, and unclear data governance and responsibility [6]. - The lack of proper consent and adherence to data protection laws raises serious concerns about user rights and data security [6].
