Capture fingerprint from Android or iOS application but compare in the cloud

"Every biometric authentication device and application performs 4 major functions: image capture, feature extraction, template creation and storage, and comparison."

This project is about identifying unconscious people in emergency incidents, where they cannot provide information to specialized first-aid staff. In such cases, this staff (e.g. doctors) might need access to an emergency dataset of the patient.

I have a database and a web app in the azure cloud platform. Part of the project is an identification system based on fingerprint recognition. I am not familiar with mobile development and I would like to ask you if it is possible to create a mobile app with the following operations:

1. image capture
2. feature extraction
3. template creation

But, I need to put the storage of the templates in the cloud. Thereafter, I have to do also the comparison in the cloud. I have already a web platform for handling the database and I can make a web service to communicate with the mobile application but I am new to biometric authentication and mobile development. Any help will be appreciated...
