Mitsuhiko Nozawa proposed a user authentication system using only image data from a normal camera. It uses face recognition to verify a user, and then hand tracking to input a password. The system combines pretrained models for face feature extraction and hand tracking. While this approach avoids costs associated with other biometric authentication methods, its main issues are the time required for password input and potential exposure of passwords to observers. Future work could focus on addressing these problems.
Automated attendance system based on facial recognitionDhanush Kasargod
A MATLAB based system to take attendance in a classroom automatically using a camera. This project was carried out as a final year project in our Electronics and Communications Engineering course. The entire MATLAB code I've uploaded it in mathworks.com. Also the entire report will be available at academia.edu page. Will be delighted to hear from you.
Face recognition is a biometric technology that goes beyond just detecting human faces in an image or video. It goes a bit further to determine whose face it is. A face recognition system works by taking an image of a face and predicting whether the face matches another face stored in a dataset (or whether a face in one image matches a face in another).

This application was design with help of OpenCv and C#.
Facial recognition (or face recognition) is a type of bio-metric application that can identify a specific individual in a digital image by analysing and comparing patterns.
Face recognition software is based on the ability to first recognize faces, which is a technological feat in itself. If we look at the mirror, we can see that your face has certain distinguishable landmarks. These are the peaks and valleys that make up the different facial features.
This application take picture of your face and after storing it.
Then it start identifying all face which are store in database.
Humans often use faces to recognize individuals, and advancements in computing capability over the past few decades now enable similar recognitions automatically. Early facial recognition algorithms used simple geometric models, but the recognition process has now matured into a science of sophisticated mathematical representations and matching processes. Major advancements and initiatives in the past 10 to 15 years have propelled facial recognition technology into the spotlight. Facial recognition can be used for both verification and identification.
A Survey on Security for Server Using Spontaneous Face DetectionIJERA Editor
In today’s computerized world, cyber crime has increased. The web network of www also increases day by day. So the protection of software and data in our computers has become very important. For this purpose we are developing the “Server Security System” with the help of some technologies such as GPRS, TCP-IP, SMTP, and MIME. In our project we are developing a system such that we get the image of an unauthorized person or user. To do this we are using a webcam. We send a mail to the authorized person's GPRS phone. For this purpose we use a mobile it can be any mobile. In parallel we are changing the password by generating a random string & then Shutting-Down the computer remotely. By using java programming we can create such applications which will help us to stop the cyber crime. It is not visible to new user so that he is unaware from this software so this will definitely helpful to make them fool.

May internship challenge: User Authentication System only using image data: Combination of face image recognition and hand tracking
1. Internship Challenge Presentation:
User Authentication System only using image data:
Combination of face image recognition and hand tracking
Author: Mitsuhiko Nozawa
Date: 2021/06/21
2. Agenda
1. Overview - brief explanation about application
2. What is Authentication System?
3. Proposed Method
4. Experiment result
5. Problem of Proposed Method
6. Future Work
3. Theme:
❏ User Authentication System with Face Recognition and Hands Tracking
Application function:
❏ Using face image, verify whether user is registered or not
❏ After that, receive password by hands tracking and do authentication
Use case:
❏ Office entrance, etc...
motivation:
❏ Face recognition is researched very active, but I felt that real-world application in authentication
system seemed is not so prevailed.
❏ Inspired from ReID
Overview (brief explanation about my app)

4 5 6
7 8 9
4. Role
❏ judge if a person is part of a particular group
Prevailed form
❏ ID・Password
❏ Card Key
❏ Biometric Authentication
Why do you need it?
❏ Demand for restricting the use to registrants only
❏ For example, the company has a lot of confidential information, and if There are no restrictions of
entering office, the information will be leaked.
Problem
❏ ID・Password:management cost per each member
❏ Card Key :risk of lost, a little contact
What is Authentication System ?
5. Biometric Authentication
❏ Do authentication with biological unique feature by each person
❏ ex) Vein authentication, Fingerprint authentication、Face authentication
❏ Used for unlocking smartphones
Among them, Face authentication has become major recently.
❏ FaceID of iPhone
❏ FaceID is used in smart phone application of financial institution
But for those face authentication, 3D features(depth) got from sensor camera are used.
And sensor camera is expensive compared to normal camera.
What is Authentication System ?
6. Initial my application Idea:
❏ Face Authentication System only using image data got from normal camera
Advantage:
❏ no risk of lost, comparably inexpensive, completely contactless
Threat:Spoofing
❏ picture, movie, dummy from 3D printer(This breaks iphone’s FaceID)
❏ It is very difficult to solve this problem in only image data situation (a cat and mouse game)
・I gave up doing authentication only using face image, and determined to use other unique information
❏ eye tracking:risk of spoofing from movie
❏ gesture:it seems difficult to recognize complex gesture
❏ password input from hand tracking → algorithm is easy, easier method is better
Conclusive my application Idea:
❏ Face recognition and Hands Tracking Password Authentication System only using image data
Proposed Method(Application Idea)
7. Face Recognition
❏ Get features of input user and registered users from pretrained feature extractor
❏ Calculate cosine similarities of each pairs of input user and registered users
❏ If maximum similarity exceeds threshold, input user is regarded as registered user who has maximum one
❏ Otherwise input user is regarded as not registered
❏ Training of feature extractor:Deep Metric Learning (arcface)
Proposed Method(Implementation)

9. Hand Tracking Password Authentication
❏ I have no time to originally construct model…
❏ So, I use MediaPipe Hands library created by google
❏ First, create circle mask which has one character in input image
❏ Get coordinate of index finger location from model
❏ If the coordinate is in particular circle, return its character
Proposed Method(Implementation)
10. Hand and Hand Skeleton detecting model created by Google.
This model is assumed to work in mobile device, so fast and light.
This model has 2 stages to output final results
1. Detect Palm from input image and crop image using bounding box
2. from cropped image, predict 21 hand skeleton point
I use number 8. INDEX_FINGER_TIP to create password.

Dataset:
❏ CASIA WebFace(for train):10,575 identities 494,414 images
❏ LFW(for test):5749 identities 13,233 images
Metric
❏ Calculate AUC from all image pairs ( 2-combinations of a set N , match or not)
Training Strategy
❏ All images are cropped (112, 112) by using MTCNN face detector
❏ Batch size is 512
❏ ResNet50 is adopted as backbone model
❏ 5% of training data is used for validation data
Experiment
13. Experiment Results
I can’t perfectly reproduce the experiment results of paper
Possible causes:
❏ need more data
❏ program has bug
❏ backbone model is not sufficient
optimizer lr scheduling loss function AUC
exp_000 SGD 0.1 Multi Step [20, 28] Cross Entropy -(too bad)
exp_001 Adam 5e-4 Multi Step [20, 28] Cross Entropy 0.827
exp_002 Adam 5e-4 no scheduling Cross Entropy 0.616
exp_003 Adam 5e-4 no scheduling Class Weighted Cross Entropy 0.633
14. ● Hand Tracking Password Authentication takes long time
❏ The more users that use it at the same time, the more the cost increases.
● Other people can watch Password while the user is using the system
❏ keep private from other people to watch when using application...
● The input user wearing a mask, glasses and so on 😷
❏ save multiple image per user
❏ use data augmentation to wear such ornaments to input user when registering
Problems of Application
15. ● I proposed user authentication system only using image data with face recognition and hands tracking
● This application solve some existing problems
❏ risk of lost
❏ sensor camera cost of face recognition
❏ spoofing
● But there are 2 severe problems
❏ Time cost of password input
❏ Password exposure
● So if you don't have a lot of users and you can keep private from other people, the application will work
well.
