Checking Liveness and Face Biometry
To check liveness and face biometry, you need to upload media to our system and then analyze them.
Below, you'll see the example of performing a check and its description.
1
let analysisRequest = AnalysisRequestBuilder()
2
// create one or more analyses
3
let analysis = Analysis.init(
4
media: mediaToAnalyze, // mediaToAnalyze is an array of OzMedia that were captured or otherwise created
5
type: .quality, // check the analysis types in iOS methods
6
mode: .serverBased) // or .onDevice if you want the on-device analysis
7
analysisRequest.uploadMedia(mediaToAnalyze)
8
analysisRequest.addAnalysis(analysis)
9
// initiate the analyses
10
analysisRequest.run(
11
statusHandler: { state in }, // scenario steps progress handler
12
errorHandler: { _ in }
13
) { result in
14
// receive and handle analyses results here
15
}
To delete media files after the checks are finished, use the
cleanTempDirectory method.To add metadata to a folder, use
AnalysisRequest.addFolderMeta.let analysis = Analysis.init(media: mediaToAnalyze, type: .quality, mode: .serverBased)
var folderMeta: [String: Any] = ["key1": "value1"]
analysisRequest.addFolderMeta(folderMeta)
...
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.let analysis = Analysis.init(media: mediaToAnalyze, type: .quality, mode: .serverBased, params: [“extract_best_shot” : true])
To use a media file that is captured with another SDK (not Oz iOS SDK), specify the path to it in the OzMedia structure (the
bestShotURL property):let referenceMedia = OZMedia.init(movement: .selfie,
mediaType: .movement,
metaData: ["meta":"data"],
videoURL: nil,
bestShotURL: imageUrl,
preferredMediaURL: nil,
timestamp: Date())
If you want to add your media to the existing folder, use the
addFolderId method:let analysis = Analysis.init(media: mediaToAnalyze, type: .quality, mode: .serverBased)
analysisRequest.addFolderId(IdRequired)
