# GBDS 5 - What's New?

### New Features

* Fusion (1:1 and 1:N) decision by biometry and mismatch
  * If micro service and libmultibio returns MISMATCH, exception and group is BIOMETRIC\_MISMATCH automatically
  * If no match is returned by fusion, API and Trust will assume NO HIT
* Now group pending can be configured to go to analysis or be directly treated
  * `TRUE`: group treatment can go to pending status, according to user permisisons over all group organizations
  * `FALSE` : group treatment is always final, regardless user permissions over all group organization
* A new validation mechanism was introduced for biometric image used in Liveness search to ensure no data was altered during transmission. This mechanism applies **exclusively** to requests made to the endpoint **POST /v2/people/searches** with search type set to **LIVENESS**.
  * Payloads (specifically the `content` of biometric images) in version 2 are now validated using a cryptographic HMAC signature.
* Added verify post match for updates processed on GBDS.
  * Update fusion rules now apply to enrolls that turned int update
* Now "get group" returns a flag indicating if the group is treatable by the user (user has to have the appropriate permissions)
* Added new behavior rules
  * Biometric Target - [Documentation](https://gitbook.griaule.com/configuracao-do-gbds/target-biometrico)
  * Biographic Target - [Documentation](https://gitbook.griaule.com/configuracao-do-gbds/target-biografico)
  * Lights Out Analysis - [Documentation](https://gitbook.griaule.com/configuracao-do-gbds/analise-de-lights-out)
  * Key Validation - [Documentation](https://gitbook.griaule.com/configuracao-do-gbds/validacao-de-chaves)

### Improvements

* Start and stop scripts updated
* Now delete person endpoint forces memory deletion without having to verify if the person is active and non erased
* New version of face quality extraction available
  * Fixes a problem where flags like busyBackgroundInCropped were being translated to faceLeft
* Native libraries libmultbio and matcher multbio updated to 0.3.4, fixing memory overhead problems and crashes
* Prioritization now is only available for groups in analysis, pending, refused created or ready to send
* Native library Facepad urgraded to 2.3.1, which is used on liveness analysis
* Matcher update
  * New face quality analysis for UPDATE, which now can return face UNCERTAIN
* Support for **new** extractors
  * Face templates simplification are no longer made on transactions/people
  * Finger templates are no longer mande on people
  * Quality control and sequence control are made using multibio comparison
* Ginger extractor updated to 2.3.0
* Query performance for list groups have been improved
* TRUST queries optimizated for:
  * get next biometric
  * get next group
  * count done/remaining groups
* Now when a group is refused, it becomes linked to all the exception groups who were responsible for the refusal - [more details](https://gitbook.griaule.com/configuracao-do-gbds/tratamento-recusado)

### Bug Fixes

* Fixed bug where update transactions in profiles that were created a long time ago were taking too long
* Fixed a bug where Trust was using biometrics from rejected transactions on Enroll Unify treatments
* Verify and update 1:1 searches now uses correctly ALL\_INDEXES and SAME\_INDEX during its execution
* Fixed a bug REFUSED status changes were not validating the user permissions
* \[TRUST] Fixed a bug where refused **enrolls** were being sent as updates
* Fixed a bug where listing people with endDate filter would return error 500
* Now if the setting for BoB (Best of Biometrics) use in an update is absent, it is set to true automatically
* Fixed a bug where UPDATE exceptions treated with only its reference being kept were getting lost
* Now listing people with "include anomalies = false" returns correctly only people not related to an anomaly
* Fixed bug where the search result was changing depending on the number of candidates
* Fixed a bug where wasn't possible to delete a person when this person was reactivated using a trusted update
* Fixed a bug where update transactions received from an update caused by the enroll of a person with non-deduplicated keys were being sent as enroll transactions instead of update
* Fixed a bug where update exceptions generated by two profiles with the same face and different fingers couldn't be treated
* Fixed a bug where refused transactions were being sent as updates instead of enrolls after reject treatments
* Fixed a collateral bug from updates with the same face and different fingers (5.1.12) where it wasn't possible to generate biometric targets nonconformities.
  * from fusion decision "UNCERTAIN" to target "BIOMETRIC", both enroll and update
  * from fusion decision "MISMATCH", treted as "NO\_HIT", to target "BIOMETRIC", only update, when one modality is "HIT" and the other is "NO\_HIT" with no uncertain biometric
* Fixed a bug where the forced BoB wasn't working properly for TrustedUpdate transactions on ETR and Print
* Fixed a bug where a failure would occur during a refused resend if the template experienced an error during extraction
* Verify post match is not performed for enroll anymore, since it could modify the fusion decision
