Leveraging the YouTube Faces Database for Deep Hashing Model Training in Earth ID

Abstract

This whitepaper explores the use of the YouTube Faces Database in training the Deep Hashing model for Earth ID, a decentralized, video-based identity verification system. We discuss how this public dataset can be leveraged to enhance the performance of the Deep Hashing model, contributing to a more secure and efficient identity verification process.

1. Introduction

Earth ID is a pioneering technology that combines artificial intelligence, video processing, deep hashing, and cryptography to provide a secure, decentralized identity verification system. A critical component of Earth ID is the Deep Hashing model, which maps video frames to a unique binary code for each user. This paper discusses the use of the YouTube Faces Database in training this model.

2. YouTube Faces Database: An Overview

The YouTube Faces Database is a public dataset designed for studying the problem of unconstrained face recognition in videos. It contains 3,425 videos of 1,595 different people, providing a diverse range of data for facial recognition tasks. The database also provides descriptor encodings for the faces appearing in these videos, using well-established descriptor methods.

3. Feature Extraction

The first step in training the Deep Hashing model is feature extraction. The YouTube Faces Database, with its diverse range of faces and expressions, serves as an excellent resource for this purpose. The model is trained to extract features from video frames that capture the unique characteristics of a person's face.

4. Hashing

Once the model has been trained to extract features, it can be further trained to map these features to a binary code using a deep hashing technique. The goal is to learn a hash function that preserves the semantic similarities among the videos, ensuring that the same person is always mapped to the exact same binary code, regardless of variations in the video.

5. Liveness Detection

The videos in the YouTube Faces Database can also be used to train a liveness detection algorithm. This involves analyzing the video stream for signs of liveliness, such as natural motion or challenge-response tasks, to prevent spoofing attacks.

6. Model Validation and Benchmarking

The YouTube Faces Database can be used to validate the performance of the Deep Hashing model. This could involve dividing the database into a training set and a test set, training the model on the training set, and then evaluating its performance on the test set. The database's benchmark tests can also be used to compare the performance of the Earth ID model with other models.

7. Conclusion

The YouTube Faces Database is a valuable resource for training the Deep Hashing model in Earth ID. By leveraging this dataset, we can enhance the performance of the model, contributing to a more secure and efficient identity verification process. As we continue to develop and refine Earth ID, we look forward to exploring other ways to leverage public datasets to improve our technology.

8. Future Work

While the YouTube Faces Database provides a valuable resource for training the Deep Hashing model, there is always room for improvement. Future work will focus on exploring other datasets and developing techniques to further enhance the performance of the model. We also plan to investigate ways to incorporate other types of biometric data into the model to further enhance the uniqueness and security of the generated hash.
