What is Digital KYC (Know Your Customer)? How is digital KYC implemented in cryptocurrency exchanges and financial software? Detailed guide and solution recommendations.
Digital KYC (Know Your Customer) is the process of verifying customers in a digital environment by financial institutions and cryptocurrency exchanges. In this guide, we will examine in detail what digital KYC is and how it is implemented in cryptocurrency exchanges and financial software.
Digital KYC is the complete digitalization of the customer identity verification process. Unlike traditional KYC processes, artificial intelligence, machine learning, and biometric verification technologies are used instead of physical document submission.
# Example: Reading ID document with OCR
from pytesseract import image_to_string
from PIL import Image
def extract_id_info(id_image):
# Extract text with OCR
text = image_to_string(Image.open(id_image), lang='eng')
# Parse identity information
id_info = {
'name': extract_name(text),
'id_number': extract_id_number(text),
'birth_date': extract_birth_date(text)
}
return id_info
Digital KYC systems calculate a risk score for each customer:
| Risk Factor | Weight | Description | |------------|--------|-------------| | Identity Verification Success | 30% | Document and selfie verification result | | Address Verification | 20% | Address proof and geographic location | | Financial History | 25% | Credit score, banking history | | Suspicious Activity | 15% | Watchlists, sanctions lists | | Device and IP Analysis | 10% | VPN, proxy, suspicious device |
Cryptocurrency exchanges are required to implement KYC to comply with legal regulations:

const kycService = new KYCService('your-api-key', 'your-api-secret');
const result = await kycService.verifyUser('user123', {
