PHP Fileinfo extension must be installed/enabled to use Intervention Image

I've used intervention image package in Laravel 5 project. It is working in local server. Now when I uploaded in shared server via cpanel, I am getting error:

MissingDependencyException in ImageManager.php line 123:
PHP Fileinfo extension must be installed/enabled to use Intervention Image.

Server has PHP Version 5.6.19
