6.19.0

This version includes updates to the facial extraction and liveness check engines. Starting with this version, Intel FMA3/AVX instructions are no longer needed, so the versions have been discontinued windows_fma3 and linux_fma3. For security reasons, Ubuntu24 has been set as the minimum Linux version to run the SDK on-premise. Support for image formats has also been added JPEG2000, both in the extraction engine and in the liveness check engine.

A coercion detector to the liveness check engine as experimental functionality. It is designed to detect cases where weapons appear in the image or where the subject's eyes are being forced open. This can be obtained through the method SelphIDNoLiveDetails::GetCoercionScore(), which will return a value between 0 (no coercion) and 1 (coercion present with 100% certainty). This functionality will not affect liveness check diagnostics in any way (Live, NoLive). For now, we offer it for informational purposes only.

Finally, new environment variables have been added to the rest service, which map the existing variables in config.json.

Added

• Coercion detection in the liveness check engine.

• SelphIDNoLiveDetails::GetCoercionScore().

• Support for JPEG 2000 images in the extraction and liveness check engines.

• New environment variables for the C++ Rest Api service:

  • FACEPHI_SELPHID_REST_PORT

  • FACEPHI_SELPHID_REST_NUMBER_OF_THREADS

  • FACEPHI_SELPHID_REST_CONNECTION_TIMEOUT

  • FACEPHI_SELPHID_REST_KEEP_ALIVE_REQUEST_NUMBER

  • FACEPHI_SELPHID_REST_CLIENT_MAX_BODY_SIZE

  • FACEPHI_SELPHID_REST_LOGGER_PATH

  • FACEPHI_SELPHID_REST_LOGGER_FILE_PREFIX

  • FACEPHI_SELPHID_REST_LOGGER_LEVEL

  • FACEPHI_SELPHID_REST_LOGGER_ROTATION

  • FACEPHI_SELPHID_REST_LOGGER_MAX_FILES

Improved

• New facial extraction engine, without the instruction set fma3.

• New liveness check engine, without the instruction set fma3.

• Improved support for detecting closed-eyes and occlusions in the liveness check engine.

Removed

• Versions fphi-selphid-sdk-linux64_fma3 and fphi-selphid-sdk-win64_fma3, since the new biometric engines do not use the extended instruction set.

• Java and .NET programming examples.

API contract updates

After the updates introduced in this version, the API contract has been revised accordingly. A new field has been added coercionScore to PassiveLivenessResult::noLiveDetails in:

• /api/v1/selphid/passive-liveness/evaluate

• /api/v1/selphid/passive-liveness/evaluate/token

{
  "diagnostic": "Live",
  "noLiveDetails": {
    "mainCause": "Unknown",
    "fPadStatus": "Passed",
    "fPadScore": 0.9,
    "fMadStatus": "Passed",
    "fMadScore": 0.8,
