Request Header Parameters

ParameterDescription
X-ACCESS-TOKENstring Please use Token Authentication API to get your access token

Request Parameters

ParameterDescription
signatureIdstring [Optional] signatureId from Get SignatureId API We strongly suggest using signatureId instead of livenessId
livenessIdstring [Optional] an identifier for your user’s face photo from the SDK
resultTypestring [Optional] Refer to resultType
regionstring [Required in Singapore]The region of the service support, format please refer to ISO ALPHA-2/ISO ALPHA-3 Country Code

Notes

  • livenessId and signatureId can not be empty at the same time.

resultType

the preferred format for the liveness image, IMAGE_URL or IMAGE_BASE64. The default will be IMAGE_URL.

Supported Valuesexplained
IMAGE_URLReturns a URL where the customer’s face image can be downloaded, the url will remain valid for only 24 hours.The availability of images in the format of image_url should be impacted and expected slow response when the public network’s situation is not in a good condition.
IMAGE_BASE64Returns the base64 string of the image

Response Description

pricingStrategyalways FREE
messageStatus Code Explanation
datadetectionResult: string The image URL or the image base64
livenessScore :double The score for anti-spoofing, ranging from [0,100], less than 50 means it might be an attack. Please refer to the Note below of given suggestions based on different liveness scores.
auditImageUrl:string The audit image link
imageFarUrl: string Photo taken by user in far stage
imageNearUrl: string Photo taken by user in near stage
farImageTime : long Timestamp of the imageFar
nearImageTime : long Timestamp of the imageNear
attackType: string Refer to attackType
attackSubType: string for future use, currently null.

Note

  • livenessScore
  • If the user’s liveness score is more than 50, that is regarded as normal behavior, and the suggestion is pass.
  • If the user’s liveness score is less than 50, that is regarded as abnormal behavior, and the suggestion is manual check.
  • imageFarUrl: Returns a URL where the customer’s face far view image can be downloaded, the url will remain valid for only 24 hours.The availability of images in the format of image_url should be impacted and expected slow response when the public network’s situation is not in a good condition.
  • imageNearUrl: Returns a URL where the customer’s face near near image can be downloaded, the url will remain valid for only 24 hours.The availability of images in the format of image_url should be impacted and expected slow response when the public network’s situation is not in a good condition.
  • auditImageUrl: Will return audit image in a link, format is zip, need to be configured in SDK first, otherwise it will be null the url will remain valid for only 24 hours.The availability of images in the format of auditImageUrl should be impacted and expected slow response when the public network’s situation is not in a good condition.
