BioID is a Biometric identity system including identity services based on .NET Core, .NET Framework, and Python. On the other hand, it also provides facial recognition service which allows you to upload your customer picture(s), and recognize them (on video, stream, image) automatically with high accuracy by using State of the Art algorithms. Read the document for more information.

Business Context

Conceptual Model

OS, SDK, library, tooling and prerequisites

Infrastructure

• Windows 10 - the OS for developing and building this demo application.
• CUDA 10.1 - a parallel computing platform and programming model that makes using a GPU for general purpose computing simple and elegant.

Back-end

• .NET Framework 4.x - .NET Framework
• Python 3.7.4 - is a programming language that lets you work more quickly and integrate your systems more effectively.

Front-end

• jquery 3.4.x - JavaScript runtime built on Chrome's V8 JavaScript engine.
• typescript - a typed superset of JavaScript that compiles to plain JavaScript.

High level software architecture

There are several individual services and infrastructure components that make up this app:

No.	Service	Description
1.	SSO (.NET Core)	Authenization and token.
2.	BioID (.NET Framework)	UI and API used to manage dataset, devices..
3.	CoreService(Python)	Detect faces, calculate distances, extract features.
4.	VideoConsoleExecute (.NET Framework)	Video maker.

## Technology

RetinaFace

• RetinaFace is a practical single-stage SOTA face detector which is initially introduced in arXiv technical report and then accepted by CVPR 2020.

• You can read more here

ArcFace

- Data :

• Refine the largest publicly available training data, MS-Celeb-1M, in both automatic and manual way.

- Network :

• Taking VGG2 as the training data, the authors conduct extensive contrast experiments regarding the convolutional network settings and report the verification accuracy on LFW, CFP and AgeDB.

- Loss :

• The authors propose a new loss function, additive angular margin (ArcFace), to learn highly discriminative features for robust face recognition.

- Performance :

• The proposed ArcFace achieves state-of-the-art results on the MegaFace Challenge, which is the largest public face benchmark with one million faces for recognition.

InsightFace

• InsightFace provides a complete implementation of both RetinaFace and ArcFace with a lot of pre-trained models.
• More information here

Installation

Step 1:

• Install Visual Studio, Python 3.7.4, CUDA 10.1

Step 2:

• Install all required package in CoreServices\FacialRecognition\requirements.txt

Step 3:

• Open BioID.sln with your VS. Then build VideoExecuteConsole to BioID.Admin\App_Data. You must put Certificate file to BioID.Admin\App_Data too.

Step 4:

• Run terminal python manage.py runserver --nothreading in CoreServices\FacialRecognition\Source.

Step 5:

• Configure information in Web.config.

Step 6:

• Run BioID.Admin and enjoy!

System advantages

Face Detection

• Very high accuracy.
• It can avoid the light and distance effects.
• Work well even the face is not frontal.

Face Recognition

• Don't like the other algorithm which is almost based on 128-d features (FaceRecongition, FaceNet...), we provide a very strong features extraction tool based on 512-d features per face.
• We just need 1 frontal face per user for the dataset.
• Our tool can avoid light effect well. (But good light effect still better)

Known issues

• Insight face works on mxnet. Unfortunately, mxnet isn't support multithreading. So, we need to lock the Thread, but it will slow our process down.
• Even Insight face is a very strong features extraction tool, it's performance not good as expect (800ms/image with CPU; 300ms/image with GPU).
• The project works on .NET so It's limited to Windows OS.

In the future

• Optimize facial recognition process.
• Update new technology while it's available.
