Question

Determine the True or False statement in the following:

1 Fingerprint is more accurate than face recognition authentication.

2 Mathematically it is possible for any hash algorithm to have two different outputs for similar input.

3 Based on something you are authentication type, it is possible for non-authorized person to be authenticated

4  Access control policy is applied after authentication step

Answer 1

1)TRUE

It depends on the requirements.But most of the cases fingerprint sensor is more accurate.

Fingerprint sensor are still better than facial recognition.

Fingerprint authentication is fast,accurate.

2)TRUE

Yes it is possible for one hashing technique called Salting.

Every time the the same input is mapped to a different hash value.

3)TRUE

Suppose the authentication type is finger print,a non-authorized person can somehow steal your finger print and get authenticated.

4)TRUE

Authentication means confirming your own identity while access control means granting access to the system.

In other terms authentication is the process of verifying who you are,while access control is the process of verifying what you have access to.

so,logically Authentication comes first and next Access control
