Program Code – Python in Biometric Security Systems
import cv2
import numpy as np
from skimage.metrics import structural_similarity as ssim
# This function will read an image from the file system
def read_image(image_path):
return cv2.imread(image_path, cv2.IMREAD_GRAYSCALE)
# This function will calculate the Structural Similarity Index (SSI) between two images
def compare_images(imageA, imageB):
score, _ = ssim(imageA, imageB, full=True)
return score
# This is the main function that simulates a biometric security system using facial recognition
def biometric_security_system(image_path, reference_image_path):
# Load the images to compare
image = read_image(image_path)
reference_image = read_image(reference_image_path)
# Check for similarity between the current and reference images
similarity_score = compare_images(image, reference_image)
# If the similarity is above a certain threshold, grant access, otherwise deny
access_granted = similarity_score > 0.8
return access_granted, similarity_score
# Sample usage
if __name__ == '__main__':
access, score = biometric_security_system('face_to_authenticate.jpg', 'reference_face.jpg')
if access:
print(f'Access Granted. Similarity Score: {score:.2f}')
else:
print(f'Access Denied. Similarity Score: {score:.2f}')
Code Output:
Access Granted. Similarity Score: 0.85
Or, it could say:
Access Denied. Similarity Score: 0.75
depending on the SSI score comparison.
Code Explanation:
The provided program simulates a biometric security system that uses facial recognition to authenticate users. Let’s dissect this code piece by piece:
- Imports: The code uses OpenCV (cv2) for image handling and scikit-image (skimage) for the structural similarity (SSI) comparison. The SSI is a metric to measure the similarity between two images.
- Read Image Function:
read_image(image_path)takes in one parameter, the path to the image, and returns the image in grayscale. Grayscale is used because for biometric comparison, color data is often superfluous. - Compare Images Function:
compare_images(imageA, imageB)computes the SSI score, determining how similar two images are. The closer the score is to 1, the more similar they are. - Biometric Security System: This is the core function. It takes two images:
image_path(the face to authenticate) andreference_image_path(the stored face used for comparison). It reads both images in grayscale and then compares them using the SSI metric. - Authentication Logic: If the similarity score is above a preset threshold (0.8 in this case), access is granted. It’s important to note that the threshold value is determined empirically and should be set based on the security requirements.
- Test Run: Under the
if __name__ == '__main__':clause, the system is put to the test with sample images. Based on the SSI comparison, an access message is printed, providing a user-friendly output displaying whether access is granted or denied and the corresponding SSI score.
The architecture of this biometric system is quite straightforward: it compares two images for similarity and decides on access based on the similarity score. Real-world systems would involve more complex algorithms and security measures, but this offers a simplified version that hinges on the core concept of image-based biometric authentication.
