Captchasonic

CaptchaSonic是一種聲波和超聲波替代現有的captcha系統。

Captchasonic is a Captcha system alternative using ultrasound communication between a web component and a mobile application.

The purpose of this free tool is to eliminate or limit the actions of spammers and robots in web pages and forms.

Instead of having to decipher a graphic captcha on the same page in which there is the stage of validation,

we provide an unique tool to achieve the same goal.

Our application is based on three mains steps:

1-Push the web component to emit an ultrasound

2-Launch on the smartphone the Captchasonic application

3-If authentication is correct then the process is validated on the website

The related SDK technology can be tested and downloaded on Captchasonic website:
