# Authentication Score

### What is an authentication Score?[​](https://doc.facesign.in/docs/Recursos/Score%20de%20autentica%C3%A7%C3%A3o#oque-%C3%A9-score-de-autentica%C3%A7%C3%A3o) <a href="#oque-e-score-de-autenticacao" id="oque-e-score-de-autenticacao"></a>

The score is an intelligent method of identifying people in which the probability that the person is authentic or not is evaluated with high efficiency.

From the client's face and CPF, the probability that the person corresponds to the CPF is evaluated. This assessment is made according to the level of knowledge one has of the person's face.

The score is a rating from 0 to 15 where a value corresponding to the assessment made between face and CPF is returned.

As shown in the table below:

|  Score  | Response                 | Action                                                      |
| :-----: | ------------------------ | ----------------------------------------------------------- |
|    0    | Does not match           | Deny registration                                           |
|  1 - 4  | Insufficient Information | Deny registration, request new authentication               |
|  5 - 10 | Sufficient Information   | Attention required, review the quality of the data acquired |
| 11 - 15 | Sufficient information   | All acquired information meets acceptable standards         |
