MyData is a system designed to empower individuals to manage and control their own personal data. The government is promoting the widespread adoption of MyData across finance, healthcare, and public sectors with the aim of strengthening data sovereignty. Through this initiative, citizens can benefit from services such as personalized financial product recommendations and integrated asset management. However, as data usage increases, establishing a secure and trustworthy data environment has become a top priority.
With the widespread use of internet banking and mobile-based financial services, personal data is collected and processed across numerous platforms. This growing complexity also raises the risk of cyber threats such as hacking, man in the middle attacks, and data tampering. Since MyData deals with highly sensitive financial information, robust system architecture that anticipates and prevents security risks from the beginning is essential.
As data breaches become more common, public concern over personal information security is rapidly growing. Information handled by MyData such as credit scores, loan histories, and transaction records is extremely sensitive. Therefore, protecting this data goes beyond technical requirements and plays a key role in building public trust. For companies, implementing strong security measures is no longer optional but a fundamental responsibility in the era of data-driven services.
MyData System Architecture and Security Threats
MyData service flow: User authentication, data collection, processing, and provision
MyData services operate based on user consent. The process typically begins with user authentication, followed by API-based data collection. Collected data is then processed and analyzed internally, and the results are provided to the user. As personal information is transmitted multiple times during this flow, ensuring data security at each step is critical.
Potential threats during actual operation
Various threats may arise in a real operational environment. For instance, access tokens could be stolen through malicious attacks, or user data might be leaked via man-in-the-middle attacks. Improperly configured systems may also allow unauthorized API requests. These risks can undermine the reliability of the entire service, highlighting the need for preventive measures.
Vulnerability in data transmission segments
Among the various components of the MyData system, the segments where data is transmitted between institutions are especially vulnerable. Even with TLS encryption, poor key management or fake certificates can compromise the security. Therefore, building secure servers and conducting regular audits are essential for protecting communication channels.
The Role of Security Servers and Legal Requirements
What is a security server and what role does it play in MyData?
A security server is a technical infrastructure that encrypts data transmitted over the internet to protect it from hacking or leakage. In MyData services, it plays a crucial role in safeguarding sensitive personal and financial information. From user authentication to data consent and API integration, the security server ensures that all exchanges are reliable and protected from unauthorized access.
SSL/TLS encrypted communication and electronic signature integration
MyData services use SSL/TLS protocols to encrypt data during transmission, ensuring safe communication between sender and receiver. This prevents third parties from eavesdropping or tampering with the data. In addition, electronic signature technology is integrated to verify the integrity of the data and confirm the user's consent, reinforcing trust and compliance.
Security guidelines by the FSI and PIPC
The Financial Security Institute (FSI) and the Personal Information Protection Commission (PIPC) provide clear security guidelines for MyData providers. These include mandatory installation of security servers and encrypted communication throughout the data lifecycle. The FSI especially emphasizes technical and administrative safeguards based on electronic financial supervision regulations.
Security server requirements under relevant laws
Under Korea’s Information and Communications Network Act and the Credit Information Act, organizations handling sensitive or personally identifiable information must transmit such data over encrypted channels. Implementing a security server is essential to meet these legal obligations, and failure to do so may result in penalties or administrative sanctions.
Security Server Implementation Cases and Technology Trends
Security server adoption by major financial institutions and fintech firms
Leading commercial banks and fintech companies in Korea have proactively adopted security servers alongside the rollout of MyData services. These systems are designed to securely process sensitive customer data, with integrated encryption (SSL) and digital signature verification mechanisms. Some companies also operate independent authentication servers and Security Operation Centers (SOCs) for real-time threat monitoring and response. Adherence to guidelines set by the Financial Security Institute is becoming increasingly common.
How security servers are applied in financial API integration
In MyData services, APIs must be securely connected from user authentication to data transmission. Security servers use TLS protocols to maintain data integrity and confidentiality, and every API request includes a digital signature to ensure authenticity. OAuth2 tokens are also managed via security servers, creating a layered defense system against session hijacking and man-in-the-middle attacks. These mechanisms form a critical part of safe financial API operations.
Enhanced security technologies: HSM, multi-factor authentication, firewall integration
Hardware Security Modules (HSM) are essential for securely managing cryptographic keys and generating digital signatures. These modules are widely implemented in the MyData authentication process. Coupled with multi-factor authentication methods such as biometrics and two-step verification, they greatly strengthen the overall security posture. Firewalls are also used to segment internal and external networks, controlling access and blocking suspicious traffic. Together, these technologies form a robust protection framework for user data in MyData systems.
The Key to Trusted MyData Services
MyData services handle highly sensitive personal information. For this reason, encrypting the communication channel is essential. A security server acts as a critical protection layer that ensures safe data exchange between users and institutions. Without it, the risk of data breaches significantly increases, directly damaging the service's credibility.
If personal information is leaked or misused, companies face not only legal consequences but also a serious loss of consumer trust. In user-centric services like MyData, data protection determines the longevity of the service. For a more robust security setup, consider visiting 이지론. Therefore, implementing both technical safeguards and a well-managed security framework is essential.
