hello webmasters, i have an app idea am currently trying to put in place, pls i want to know if its possible to have an app installed to mobile device and that app to be able to restrict that phone to only one user, my app would require a phone number during registration but i want where the user cant change the sim to register another account on same app and phone. thanks. hope i was able to pass the message properly

It's possible and it's not possible. Let me explain why...

There are ways to be able to track users. Some of which are through:

1. IP addresses: If you use IP, the person can always change their IP address. There are IP resellers all over the place
2. Emails: We know one perosn can have 1 million Email addresses if they want to. So this is a no no.
3. Cookie system: You can store cookies on people's system to know whenever they access your site. But they can always use another phone to register for a new account
4. Etc


So, i think the best way to go about it is to use some form of unique identification such as an international passport, National ID card, BVN and other forms of unique identification. That way people cannot cheat the system and even if they intend to cheat, the stress in doing so will discourage them. I don't think they want to go through the stress except your app is some form of money multiplier app.

Well, since it's a mobile app, it is very possible. Every mobile phone has a unique IMEI number (except clones & IMEI hacks) which you can use to identify a device. Just keep track of this number and you have device level authentication.

Never really thought of this and now i'm seeing the OP's question in a different light.

thanks boss, i just saw this method on quora as well, will look to exploit it.............to bother you one last time do you think its that easy for an average nigerian app developer to develop this functionality into an app? am asking because am looking to setup a startup to build my app, and am looking to hire a full time staff developer as i dont have knowledge on coding. so i want to know if this function can be done easily. thanks again

Very well yes. It's not difficult to implement this specific feature. You can even eliminate most of the threats from clones and IMEI hacks by using a combination of the IMEI & user's phone number, retrieved directly from the SIM rather than have the user input it but this will probably not work on some older devices.
Combining both approaches with SMS auto verification will give you a pretty strong identfication system.
