High-Level Design(HLD) for Authentication System Design

High-level design provides a indepth overview of the overall system architecture, which describes the interaction between major components. It mainly focus on the system’s structure, major modules, and the flow of data. Key components in the high-level design of an authentication system are described as follow:

Let’s understand High Level Design of the Authentication System :

1. User Registration Section:

• Data Acquisition
  • User provides registration information.
  • System acquires and validates user data.
• Pre-processing and Feature Extracting
  • Raw user data undergoes pre-processing for normalization and cleaning.
  • Features are extracted for use in the registration process.

2. Login Section:

• Data Acquisition
  • User provides login credentials.
  • System acquires and validates user login data.
• Pre-processing and Feature Extracting
  • Raw login data undergoes pre-processing for normalization.
  • Features are extracted for authentication.

3. Real-Time Authentication Section:

What is a model?
A “model” refers to a representation or set of parameters that characterize a specific user’s behavior or characteristics. These models are generated based on the registered user data and are stored in a database for real-time use during the authentication process.

• Model Generation
  • Models are generated based on registered user data.
  • Model parameters are stored for real-time use.
• Model Database
  • The database stores generated user models.
• Classifier (if True)
  • Classifier determines if the user is legitimate.
  • If classified as true, user is authenticated.
  • System welcomes and grants access to the authenticated user.
• Classifier (if False)
  • If classified as false (imposter), the system initiates imposter rejection.
  • Appropriate actions are taken to prevent unauthorized access.

Keeping your important digital information safe is like building a strong foundation, and the key to that is a good security system. This article will help you understand how to make a robust security system step by step. We’ll start with figuring out what you want to protect and what you want to achieve. Then, we’ll talk about the detailed design aspects, like how the system works at both the small and big levels, the structure of the database, using smaller specialized services, and making sure the system can handle more load without slowing down.
