Identity Authentication - Definition, Working & More

What is Identity Authentication?

Identity authentication is the process of confirming that a person or organization is who they say they are. Before providing access Identity authentication confirms credentials like passwords, fingerprints, or multi-factor authentication (MFA). It plays an important role in safeguarding networks, systems, and private information. 

How Does Identity Authentication Work?

Identity authentication works through a series of steps to ensure secure access:

1. Credential Submission

The first step of identity authentication is to provide user credentials like username, password, or biometric data (fingerprint, facial recognition, etc.) to the system. Once these credentials are verified the user will get the access they want.

2. Verification Process

Once the credentials are given to the system, they will be mapped with the data stored in the database records. The identity data is matched through secure databases that store encrypted identity information.

3. Multi-Factor Authentication (Optional)

A lot of systems use multi-factor authentication (MFA), which is an additional step in the identity authentication process. This requires the user to provide extra verification steps like an authentication app or a one-time passcode (OTP) texted to their mobile device.

4. Access Granted/Denied

After all the credentials including the additional authentication factors are submitted and verified, the system will grant access to the user. Access is refused if there is a discrepancy, and the system may ask for additional verification or block the attempt.

5. Audit Trail

Systems that intend to ensure compliance and keep track of access for security monitoring purposes can maintain a track of identity authentication attempts.

Benefits of Identity Authentication

Identity authentication provides several critical advantages:

1. Enhanced Security

Identity authentication in systems will enable businesses to reduce the possibility of breaches and cyber-attacks. This will help the business prevent unauthorized access to sensitive data.

2. Regulatory Compliance

With identity authentication, organizations can strictly follow industry standards. These regulations like GDPR, HIPAA, and PCI DSS mandate strict identity verification protocols.

3. Trust and Reliability

Identity authentication encourages a safe workplace for everybody. The guarantee that only authenticated users can see the confidential data, makes it trustworthy between clients, partners, and employees.

4. Mitigation of Fraud

With proper identity authentication methods, the chances of identity theft, phishing, and other forms of fraudulent activities can be drastically reduced.

Common Use Cases for Identity Authentication

There are several sectors and industries in which identity authentication can be applied:

1. Internet Banking

In the banking sector, financial and transactional information is highly sensitive. Authenticating identity with multi-factor authentication ensures that only authorized account holders and personnel can have access to these pieces of information.

2. Healthcare Systems

Identity authentication is used in the healthcare sector to authenticate staff and patient’s identities. It helps hospitals and clinics to safeguard personal health information and stay compliant with HIPAA rules.

3. E-commerce

Identity authentication can be implemented within the e-commerce industry to verify the identities of customers during transactions. This helps online retailers protect payment data and prevent fraudulent purchases.
