Gender privacy angular constraints for face recognition

Description

This repository contains code to reproduce the results from our paper "Gender Privacy Angular Constraints for Face Recognition" published in the journal IEEE Transactions on Biometrics, Behavior, and Identity Science in 2024. By applying angular constraints during model finetuning, the project aims to minimize the risk of revealing individuals' gender information, thereby enhancing privacy at the template level of face recognition systems.

Installation

To install the necessary dependencies for this project, use the provided requirements.txt file:

pip install -r requirements.txt

Data and Pretrained Models

The project utilizes datasets such as LFW, AgeDB, ColorFeret, and a sample of VGGFace2 for verification and evaluation of gender privacy. You can download the binary files containing the images for evaluation as well as the pre-trained privacy-enhanced layers for each backbone here.

Training

Ensure that your image dataset is organized in a specific folder structure. The root folder of the dataset should contain subject folders, and within each subject folder, you should place the images belonging to that subject. The subject folders should be named subjectid_gender:

• subjectid: A unique identifier for the subject.
• gender: The perceived gender expression (feminine 1 or masculine 0) of the subject. A sample directory tree could be:

dataset_root/
├── MariaCallas_1/
│ ├── image1.jpg
│ ├── image2.jpg
│ └── ...
├── ElvisPresley_0/
│ ├── image1.jpg
│ ├── image2.jpg
│ └── ...
└── ...

After specifying the training configurations in the file [./config/config.py], run this command:

python finetune.py

Please refer to our paper for the choice of hyperparameters.

Evaluate

python eval/evaluation.py --log_root "path/to/log" --model_root "path/to/model/directory"  --experiment-name "experimentname" --reference_pth "path/to/reference/csv/results" 

experiment-name should refer to the different types of training settings. For instance if you train using only one dataset e.g ColorFeret, experiment-name = OneDataset/ColorFeret. The script evaluate.py will run the evaluations of all the models generated with this experiment setting.
