Access files in storage folder only through Auth Middleware and Token based authentication

I have following folder in my Laravel website.

/storage/Asset/Media

This folder can have info like below

/storage/Asset/Media/1/abc.png

/storage/Asset/Media/2/abc.png

Here 1 or 2 is the folder names.

I have following code to secure the folder so that nobody can access the folder without authentication

Route::group(['middleware' => ['web', 'auth']], function () {
    Route::get('/storage/Asset/Media/{ID}/{eded}', array(
        'as' => 'Files',
        'uses' => 'User\Account\Media\MediaController@DownloadMedia',
    ));
});

so in this way nobody can access the files until user's session is not expired in a browser.

Issue is in Android, so now nobody can access the files due to Auth Middleware.

Can somebody suggest the approach such that, files can be accessible only via Token Based Authentication and also using Auth Controller?
