FIDO, international standard for convenient universal biometric authentication.



swIDch Auth Package provides groundbreaking FIDO-based authentication functions that resolves the issue of vulnerability posed by ID and password methods. Utilizing authentication based on user’s biometrics (e.g., fingerprints, faces, etc.), you can expect a secure environment of the highest standard from simple log-in functions to electronic signatures.
Devices capable of recognizing biometrics (e.g., fingerprints, faces, etc.) provide more convenient and quicker
authentication. User biometric information is neither sent nor saved to the server, making it more secure.
On the mobile device screen, users can verify themselves using a registered pattern.

Without the need for a complex password, users can verify themselves by setting a 4-digit or 6-digit simple PIN number.
PC Log-in
If generated QR codes from PC log-in screens are scanned using mobile device cameras or the code is
inputted, the PC will be logged in.
Digital Signature
Using FIDO transactions, we provide encryption and digital signature PKI functions within the mobile
environment such as data integrity encryption/decryption and user and data authenticating electronic
signatures. (PKCS #7 standard digital signature)
Private Key
Implementing a private key system based on FIDO authentication technology, we create a PDF digital signature
that can be used for electronic contracts and agreements. (PKCS Detached standard digital signature)
They provide FIDO SDK related administrator functions such as user management, service maintenance, and
log management (authentication registration, success, and failures).

mOTP, robust 2FA in cyber security

swIDch Auth Package provides easy-to-use mobile OTP functions for situations that require more powerful authentication in cyber security. Unlike existing OTP, mobile OTP can generate one-time passwords without physical security devices by using a mobile application. Thus, you can build a very powerful identity verification system.
* * * *
Mobile OTP
An OTP (One Time Password) that can be immediately generated from a mobile device without having to carry it around
separately (e.g., physical card types, token types, etc.).
Separate from the ID and password, it is an additional authentication (2FA/MFA) method that uses a new password each time.
PIN Linkage
We verify the PIN registered by the user before generating the OTP and use its encryption value as the linkage
information to generate the OTP to enhance security.
Transaction OTP
After generating an OTP linked to financial transaction information such as payee information, account number,
remittance amount, etc., we can respond to memory hacking or MITM (intermediate attack) in a much safer manner.
