Checking Liveness and Face Biometry
To check liveness and face biometry, you need to upload media to our system and then analyze them.
Here’s an example of performing a check:
Kotlin
Java
analysisCancelable = AnalysisRequest.Builder()
// mediaToAnalyze is an array of OzAbstractMedia that were captured or otherwise created
.addAnalysis(Analysis(Analysis.Type.BIOMETRY, Analysis.Mode.SERVER_BASED, mediaToAnalyze))// or ON_DEVICE if you want the on-device analysis
.build()
//initiating the analyses and setting up a listener
.run(object : AnalysisRequest.AnalysisListener {
override fun onStatusChange(status: AnalysisRequest.AnalysisStatus) { handleStatus(status) // or your status handler
}
override fun onSuccess(result: RequestResult) {
handleResults(result) // or your result handler
}
override fun onError(error: OzException) { handleError(error) // or your error handler
}
})
analysisCancelable = new AnalysisRequest.Builder()
// mediaToAnalyze is an array of OzAbstractMedia that were captured or otherwise created
.addAnalysis(new Analysis(Analysis.Type.QUALITY, Analysis.Mode.SERVER_BASED, mediaToAnalyze)) // or ON_DEVICE if you want the on-device analysis
.build()
//initiating the analyses and setting up a listener
.run(new AnalysisRequest.AnalysisListener() {
@Override
public void onSuccess(@NonNull RequestResult list) { handleResults(list); } // or your result handler
@Override
public void onError(@NonNull OzException e) { handleError(e); } // or your error handler
@Override
public void onStatusChange(@NonNull AnalysisRequest.AnalysisStatus analysisStatus) { handleStatus(analysisStatus); } // or your status handler
})
To delete media files after the checks are finished, use the
clearActionVideos method.To add metadata to a folder, use the
addFolderMeta method.Kotlin
Java
.addFolderMeta(
mapOf(
"key1" to "value1",
"key2" to "value2"
)
)
.addFolderMeta(Collections.singletonMap("key", "value"))
In the
params field of the Analysis structure, you can pass any additional parameters (key + value), for instance, to extract the best shot on the server side.mapOf("extract_best_shot" to true)
To use a media file that is captured with another SDK (not Oz Android SDK), specify the path to it in OzAbstractMedia:
val file = File(context.filesDir, "media.mp4") // use context.getExternalFilesDir(null) instead of context.filesDir for external app storage
val media = OzAbsractMedia.OzVideo(OzMediaTag.VideoSelfieSmile, file.absolutePath)
If you want to add your media to the existing folder, use the
setFolderId method: .setFolderId(folderId)
