Need Help with how to integrate Biometric Fingerprint Authentication using Android External Fingerprint Scanner in your Android App using an External Fingerprint Scanner? I will show you how I did it and I can Help You, Your Company, Organisation or Institution to integrate with the same too !

Background Information

Have you realized in recent times that almost everything you could do on a computer you can now do it on an Android Phone and even do it more conveniently while on the move?

Computing power is gradually moving to hand held devices ( let’s say it aleady did )

A few years ago you needed to check into a Cyber Cafe to check your e-mails. Nowadays you do not have to do that ! Your can check e-mails from your Android Phone.

I have been able to do computer processing tasks like designing data flow diagrams from an Android Phone App which in the yester years would have required me to have a computer at my disposal to execute them.

With Android Phones gaining more computer processing power we expect to be able to run many other computer specialized tasks on our computer hand held devices ( …the Android Phones )

The need for Identity Software Solutions to adapt to the changing modern times and recent technology advancements has created scenarios where businesses and organisations find that there is need to be able to do Biometric Fingerprint Authentication in remote and disparate geographic locations using Android Phones.

I have previously had some of our current clients request for Biometric Fingerprint Authentication integration on their Android Operating Systems platforms after they successfuly integrated with our other Web Browser based Biometric Fingerprint Authentication Software packs

Let’s continue …

This prompted me to develop Jomutech Android Biometric Fingerprint Authentication software application that can be customized and integrated with a variety of database back-ends like Oracle, MSSQL, PostgreSQL, Cassandra, MySQL etc. to meet diverse Android Biometric Fingerprint Authentication integration needs and user requirements.

Jomutech Android Biometric Fingerprint Authentication can be integrated with every other Company, Organisation or Institution’s Android App that needs to be intefaced with Biometric Fingerprint Authentication features.

This page will show you some of the features of Jomutech Android Biometric Fingerprint Authentication Android Software pack in Pictures and explain how they work. I will tell you about the accessories you need for an Android Phone to be able to use it. Toward the end I will also give you contacts you can use to discuss with me your Biometrics integration needs for your Company, Organisation, Institution’s Android Biometric Fingerprint Authenticcation integration.

Accessories you need for Android External Fingerprint Scanner

In order for you to capture fingerprints for purposes of fingerprint enrollment and fingerprint authentication, you will need 2 items. They are;

  1. OTG cable (USB On-The-Go). This is a cable that allows your Android Phone to become a USB host that can read data from a USB peripheral device like a Flash drive, Pointing Device, External Hardisk etc. but in this case you will use it to create a USB connection between your Android Phone and your Fingerprint Scanner / Reader.
  2. Fingerprint Scanner / Reader . You will need a Fingerprint Scanner to capture fingerprint data into the phone. Basically, the OTGcable will be the conduit between your Android Phone and the Fingerprint Scanner.

Recommended Fingerprint Scanner / Reader(s) for Android External Fingerprint Scanner

Not every other Fingerprint Scanner / Reader in the market can work with an Android Operating System. Take note that Android Operating System is a derivative of Linux Operating System

Upto now, there are very many Fingerprint Scanners / Readers which do not work with any other Operating Systems save for Windows only. This implies that they do not yet support Android Operating System and will thus not work on an Android Phone.

As a result of this, you will find that there are few Fingerprint Scanners / Readers that you can rely on to use with your Android Phone to implement Biometric Fingerprint Authentication. The below is a list of Industry tested, reliable and trusted fingerprint devices that work seamlessly with Android Phones. They are arranged in no particular order.1. DigitalPersona 51002. DigitalPersona 51603. DigitalPersona 52004. DigitalPersona 53005. Eikon Touch 5106. Eikon Touch 710

If experimenting is not for you and you simply want a guarantee for what works in the market and you want to set your project milestones on a success trajectory path from the very onset, then these are the Fingerprint Reader / Scanners that will work well with your Android Application’s Biometric Fingerprint Authentication.

Back-End Database, User Particulars and Biometric Data Enrollment

The Back-End Database used is SQLite.

Currently, I save the User Biometric Data and User Particulars in SQLite. A full integration with a Company’s database is required to achieve centralized storage of all Biometric Data and User Particulars from other Mobile Phones enrolling Users’ Biometric Data in remote places and different Geographic regions.

SQLite should be used for temporary storage of biometric data. If this application is integrated with your Company’s database, code can be added that polls and listens for your dedicated network availability and then initiates ( …in the background) automatic sending of biometric data and user particulars captured during user enrollment to your main Company’s server databases like MSSQL, Oracle, MySQL, PostgreSQL etc. for long term archiving.

Fingerprint Authentication

Currently, Fingerprint Authentication retrieves Biometric Data and User Particulars for Android Biometric Authentication from SQLite in the Android Phone. This is so for ease of demonstrating its Android Biometric Fingerprint Authentication features and their functionality.

To make this Android application to be able to perform Biometric Authentication e.g. using Biometic Data captured and enrolled from your Company’s or Organisation’s Android Phones in different geographic regions and places, you will need to integrate it with your centralized and consolidated database to perfom Biometric Authentication from the universal pool of everyone’s enrolled Biometric Data and User Particulars

Installing Jomutech Android Biometric Fingerprint Authentication App

The App will require to be granted the following rights for it to be installed. They afre;

  1. Take Picture and Videos – This will allow the Fingerprint Reader / Scanner to capture Fingerprint images during Fingerprint Enrollment and Fingerprint Authentication. The Fingerprint Scanner behaves in a way like a Camera hence the need for the Android Application to request for this privacy right.
  2. Read the Contents of your SD card – This will allow Fingerprint Reader / Scanner to save Fingerprint images in SD card. I will be removing request for this right as I later decided to save Fingerprint images in the Android Phone’s SQLite databasebefore they are later transfered to the Company’s or Organization’s centralized database.
  3. Full network access – This right will allow your Android Biometric Fingerprint application to synchronize its SQLite database with that of your Company or Organisation.
