A Study on Establishing an Independent Adult App Distribution Channel and Biometric-Based Precision Verification Biosystem Free from Mainstream App Stores

1. Research Background and Problem Statement

In the current mobile application ecosystem, applications rated for adults (19+) (such as dating apps, anonymous communities, and adult content) are bound by the strict review policies and youth protection guidelines of the Google Play Store and Apple App Store. At the same time, they remain constantly exposed to minors' unauthorized bypass and exposure risks due to the vulnerabilities of superficial, one-time initial identity verification (e.g., mobile carrier name theft or using parents' accounts).

The traditional centralized app market system has structural limitations relying entirely on the unilateral policies of mega-platforms. Public agencies and judicial authorities also remain limited to a "reactive response" framework where investigations begin only after actual illegal acts or crimes occur. To resolve these structural contradictions, this study proposes a "standalone adult app distribution biosystem" that completely separates 19+ apps from mainstream app store networks and integrates designated professional certification authorities (such as medical institutions or official certification centers) alongside biometric technology, thereby establishing a proactive security infrastructure.

2. Structural Limitations of Current App Store Adult Content Distribution and Verification Systems

Loopholes in the Initial Verification Process: Current mobile adult verification primarily relies on mobile carrier identity verification or ID card OCR scans. However, once an account is created, there is a total lack of continuous monitoring mechanisms to control situations where another person (such as a minor child) shares the device or hijacks the session.
The Two-Sided Nature of Platform Review Policies: While the app store's strict blocking policies serve as a minimum defense against illegal and harmful content, they paradoxically trigger a "balloon effect" that drives youth toward underground bypass routes (such as unauthorized web browser-based sites).
Limitations Centered on Post-Incident Punishment: Because investigations by public agencies such as the police can only intervene after a report or damage occurs, the absence of a technical and structural preventive system that fundamentally blocks minors from signing up has emerged as a major social issue.

3. Proposed Model: Independent Adult App Distribution Channels and Biometric Precision Verification Biosystems

The core model proposed in this study completely isolates 19+ applications from mainstream app store ecosystems such as Google and Apple, constructing a closed, independent digital distribution network (Dedicated Adult App Storefront) linked with offline adult specialty stores, designated medical/health institutions, or official certification centers.

       │ (User device integration)

[Standalone Adult App Store (Closed Channel)]
       │ (Download & real-time continuous biometric authentication active)
       ▼
[Secure Adult-Only Service Usage]

Dedicated Storefront (Closed App Market): Unlike open markets accessed by the general public, this establishes an independent digital distribution platform accessible only through a dedicated client by users who have completed adult verification.
Medical Institution and Official Center-Linked Biometric Registration: Moving away from conventional non-face-to-face bypass verification methods, the initial right to use the app is granted by registering precision biometric data (such as facial skeletal structure and iris complex biometric data) through offline, face-to-face interactions at designated official institutions (e.g., public health centers, designated medical institutions, official certification centers) to definitively establish adulthood.
On-Device Continuous Biometric Verification: While using the app, the smartphone's front-facing sensors and NPU are utilized to match whether the actual device user is the registered adult in real time, applying a robust security layer that instantly terminates the session if a minor or unauthorized third party is detected.

4. Technical Implementation Strategies and Security Architecture

Privacy-Preserving On-Device Processing: Biometric data is designed to be processed and matched exclusively within the user device's hypervisor or Trusted Execution Environment (TEE) without being stored on a central server, ensuring immediate deletion after verification to comply with personal information protection laws and global privacy regulations.
Integration of Multi-Factor Assurance: Moving beyond simple image recognition, liveness check (real-time biometric reaction detection) technology is introduced to fundamentally block bypass attempts using photographs or deepfake videos.
Inter-Server Communication Encryption and Integrity Verification: End-to-End Encryption (E2EE) is applied during packet transmission between the independent app store and the client to prevent forgery, tampering, and packet sniffing.

5. Expected Effects and Academic/Policy Significance

Fundamental Blocking of Minor Access: By resolving blind spots in existing app stores and combining face-to-face authentication with continuous biometric monitoring, the exposure rate of minors to harmful apps converges close to 0%.
Resolution of Platform Regulatory Risks: It distributes legal sanctions and social responsibilities faced by IT companies and app developers while establishing a sound digital ecosystem order.
Transition to a Proactive Administrative Paradigm: It can serve as foundational academic data for evolving public safety systems—previously dependent on reactive investigations—into a technology-based "proactive public security model."
