ONEDROP
OneDrop is a digital healthcare solution designed to support the prevention, improvement, and management of diseases. By integrating smartphones with biosensors and IoT devices, it enables users to easily and reliably measure blood components and perform molecular diagnostics. Based on Bluetooth Low Energy (BLE) communication, the system is designed to collect and analyze real-time data while securely storing it through a cloud-linked architecture.
Additionally, it offers more precise and personalized health management services through machine learning-based pattern recognition and advanced diagnostic algorithms.

CHALLENGES
- Device Accuracy and Compatibility: Ensuring accurate measurements and stable BLE connections across various sensor devices is technically demanding.
- Regulatory Compliance: Must meet stringent healthcare data regulations (e.g., HIPAA, GDPR) to protect user privacy and enable broader deployment.
- User Engagement: Sustaining long-term user interest requires intuitive UX design and clear, actionable insights from the system.
- Data Security and Trust: Handling sensitive health data necessitates robust encryption, secure cloud infrastructure, and transparent policies.
SOLUTIONS
- Seamless BLE Integration: OneDrop ensures stable and low-energy communication between mobile devices and biosensors, enabling real-time health monitoring.
Cloud-Based Data Storage: Health measurements are securely stored in the cloud, allowing users to access historical data across devices and enabling data synchronization.
Personalized Health Insights: By applying machine learning, the platform delivers tailored recommendations based on individual health patterns, improving user engagement and preventive care.
Multi-Profile Support: The system supports managing multiple patient profiles within a single account, making it ideal for caregivers and family use.
FEATURES
- User Registration and Login (including SNS Login): OneDrop allows users to create an account easily using their email or phone number, and also supports quick login via social media accounts such as Google, Apple, or Kakao. The authentication system ensures user data is securely managed, and account access is seamless across devices.
- BLE (Bluetooth Low Energy) Communication: The platform connects to biosensors and medical IoT devices via BLE technology. This low-power communication method ensures stable, real-time data transmission between the user’s smartphone and health monitoring devices.
- Blood Component Measurement: Through connected biosensor devices, OneDrop enables users to measure various blood components such as glucose levels, proteins, and other molecular indicators. The measurement process is guided through the app, with clear instructions and automatic data retrieval.
- Data Storage and Management: Every health measurement collected is securely stored in a cloud-based system. Users can access and manage their historical health records anytime, with data presented in charts and summaries for better understanding. The system also enables syncing across devices and ensures that even offline data is safely updated when reconnected to the network.
- Patient Information Creation and Management: OneDrop allows users to create and manage detailed patient profiles, whether for themselves or for family members. Each profile includes personal data, health history, and related medical notes.
- Healthcare Solution and Smart Recommendations: Using machine learning algorithms, OneDrop analyzes health data over time to identify patterns and detect potential risks early. Based on this analysis, the system provides personalized health insights and lifestyle recommendations—such as adjusting diet, increasing physical activity, or consulting a physician."
