Captcha or similar validation technique in ionic app

Ionic Framework ionic-v3
1

I’m trying to add captcha to ionic 2 app using angular2-recaptcha.

First I created CAPTCHA sitekey of reCAPTCHA Android and added my package name, but it gives me the error “ERROR for site owner: Invalid domain for site key”.

Second try was made by using reCAPTCHA v2 with configuration of not to match the origin, and faces the same error “ERROR for site owner: Invalid domain for site key”.

How to use Captcha in ionic 2 app, or is there any similar technique provided by ionic which I can use to validate human or robot?

Why you don’t use a mathematic equation like : 5 + 2 = ?
