Model Card

1. Model Overview

FaceAuthenticator.keras is a deep learning model developed by Prathmesh Patil for classifying facial images as real or fake. The model uses the VGG16 convolutional neural network (CNN) architecture to extract visual features and distinguish between authentic facial images and potentially manipulated or synthetic images. The model is designed for experimental applications in facial image classification and deepfake detection.

3. Intended Use

Direct Use

The model can be used to classify facial images into real and fake categories. It is intended for experimentation, educational purposes, and prototyping computer vision applications involving facial image authenticity.

Downstream Applications

Potential applications include:

• Deepfake detection prototypes.
• Facial image authenticity analysis.
• Computer vision research and experimentation.
• Integration into web applications and image analysis tools.
• Development of educational projects involving CNN-based image classification. The model may require additional training, calibration, and evaluation before being adapted to a specific application.

Out-of-Scope Use

The model is not intended to serve as a standalone identity verification or access-control system. It does not establish a person's identity or determine whether an individual is authorized to access a system. It should not be used as the sole basis for security-critical decisions, identity verification, or other high-impact applications.

4. Training Data

The model was trained using a dataset containing facial images categorized into real and fake classes. The dataset follows the directory structure below:

dataset/
├── dataset-metadata.json
├── train/
│   ├── fake/
│   └── real/
├── train.csv
├── valid/
│   ├── fake/
│   └── real/
└── valid.csv

The training and validation datasets are organized to support supervised binary image classification. Detailed information about the dataset's origin, size, demographic composition, and collection methodology has not been specified.

5. Training Procedure

The model uses the VGG16 architecture to learn visual features from facial images and classify them into the designated categories. Reported training configuration:

• Architecture: VGG16
• Training Epochs: 10
• Learning Approach: Supervised learning
• Task: Binary image classification
• Reported Accuracy: Approximately 82% The reported accuracy should be interpreted in the context of the dataset and evaluation procedure used during development. Independent testing is recommended to assess generalization to unseen images and different data distributions.

6. Performance and Evaluation

The model achieved an approximate accuracy of 82% during its reported evaluation. Performance may vary depending on image quality, image preprocessing, compression artifacts, facial occlusions, and differences between the training data and real-world inputs. Further evaluation using independent test datasets and metrics such as precision, recall, F1-score, and a confusion matrix would provide a more comprehensive assessment of model performance.

7. Limitations and Potential Risks

The model has several limitations that users should consider:

• Dataset dependency: Performance depends on the quality, diversity, and representativeness of the training data.
• Generalization: The model may perform differently on images from sources or domains not represented during training.
• Image quality: Low resolution, compression, poor lighting, and occlusions may affect predictions.
• Potential bias: Underrepresentation of particular demographic groups or image-generation techniques may lead to uneven performance.
• Prediction reliability: An individual prediction may be incorrect, even when the model performs well overall.
• Evolving manipulation techniques: New image-generation and manipulation methods may reduce the model's effectiveness over time. The model's predictions should be treated as estimates rather than definitive proof of image authenticity.
