# Capabilities ### Liveness **Objective**: verify whether the user is real and alive at the moment of the selfie capture. **Possible responses**: * `YES` — user alive. * `NO` — failed liveness attempt. {% hint style="info" %} To use Liveness in by Client, the Unico SDK implementation is mandatory. {% endhint %} ### Identity Verification **Objective**: ensure that the face being submitted belongs to the holder of the identification document number. **Possible responses**: * `YES` — face corresponds to the holder of the identification document number. * `NO` — does not correspond to the holder of the identification document number. * `INCONCLUSIVE` — insufficient evidence to determine whether the face corresponds to the holder of the identification document number. {% hint style="info" %} If the response is "inconclusive", we can orchestrate with the Risk Score and return a probabilistic response. {% endhint %} ### Behavior Alert **Objective**: complement identity verification with behavioral analysis to detect identity-associated risk. **Possible responses**: * `YES` — signs of fraud associated with this face. * `INCONCLUSIVE` — no signs of fraud associated with this face. ### Risk Score **Objective**: used together with Identity Verification if its result is "INCONCLUSIVE", generates a probability score to assess whether the user's face matches the holder of the identification document. **Possible responses**: * **Positive Score (+10 to +100)**: High probability of being the real holder. * **Zero Score (0)**: Registration error. A new capture is required. * **Negative Score (-10 to -100)**: High probability of *not* being the real holder. | Classification | Score | Recmmendation | | :------------: | :------------------: | :------------------------------------------------------------------------------------------------------------------------: | | Negative | Between -40 and -100 | We recommend denying the registration. | | Negative | Between -10 and -39 | We recommend that the client evaluate the risks involved to make a decision. | | Neutral | Zero Score | We recommend denying the registration and requesting the user to perform a new capture with the actual CPF holder's photo. | | Positive | Between +10 and +49 | We recommend that the client evaluate the risks involved to make a decision. | | Positive | Between +50 and +100 | We recommend approving the registration. | ### Validation (1:1) **Objective**: confirm whether the current face is identical to the face used in a reference process. **Possible responses**: * `YES` — the face is the same one that was used in the reference process. * `NO` — the face is not the same one that was used in the reference process. ### Intelligent Revalidation **Objective**: evolution of 1:1 validation, indicated for scenarios where biometrics are not mandatory, combines **metadata** and/or **authenticated passkey** with the biometrics already performed, approving about **70% of cases automatically** and directing the remaining ones to traditional validation by **selfie.** **Possible responses**: * `YES` — indicates that the user performing the transaction is the same one who completed the validation in the process used as reference. * `NO` — indicates that the user performing the transaction is not the same one who completed the process used as reference. {% hint style="info" %} This capability is available only through the by Unico integration method. {% endhint %} ### Reuse and document capture **Objective**: request, store and reuse documents. We offer the possibility of reusing users' personal documents (*Brazilian passport, CIN, RG and CNH - digital and common*), reducing the friction of this process which usually has high abandonment. And if we do not have the documents in the database, it is possible to capture them. **Possible responses**: * **Classification**: indicates which type of document was identified. * **Data extraction (OCR)**: consists of extracting the document data from an image. * **FaceMatch**: consists of comparing the selfie face with the document face. * **CPF Match**: consists of searching the specified document for a given CPF. ### Electronic signature **Objective**: allow a user to sign digitally using biometrics (selfie), for processes that require a qualified signature. **Possible responses**: * Binary of the signed document. {% hint style="info" %} This capability is available only through the by Unico integration method. {% endhint %} #### Serpro similarity return **Objective**: specific functionality for payroll-deductible credit operations (INSS) or others that require comparison with Serpro's databases. **Possible responses**: * **Score between 0-100**: when Serpro finds the face); * **Score -1**: when Serpro does not find the face; * **Score -2**: when there is an error in the integration with Serpro and we cannot return the similarity score. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://devcenter.unico.io/unico-idcloud/product-guides/getting-started/capabilities.md?ask= ``` The question should be specific, self-contained, and written in natural language.
