Since Android and iOS 8.0.0, we have introduced the hybrid Liveness analysis mode. It is a combination of the on-device and server-based analyses that sums up the benefits of these two modes. If the on-device analysis is uncertain about the real human presence, the system initiates the server-based analysis, otherwise, no additional analyses are done.
- You need less computational capacity: in the majority of cases there's no need to apply the server-side analyses and fewer requests are being sent back and forth.
- The accuracy is similar to the one of the server-based analysis: if the on-device analysis result is uncertain, the server analysis is launched. We offer the hybrid analysis as one of the default analysis modes, but you can also implement your own logic of hybrid analysis by combining the server-based and on-device analyses in your code.
- Since the 8.3.0 release, you get the analysis result faster, and less data will be transmitted (by up to 10 times): the on-device analysis is enough in the majority of cases so that you don’t need to upload the full video to analyze it on the server, and, therefore, don’t send or receive the additional data. The customer journey gets shorter.
The hybrid analysis has been available in our native (mobile) SDKs since 8.0.0. As we mentioned before, the server-based analysis is launched in the minority of cases, as if the analysis on your device has finished with a certain answer, there’s no need for a second check. This results in less server resources involved.
