<p>Protect access to all your media files and implement your own custom file access rules using a hook. Works for apache with mod rewrite or nginx with some custom configuration. No Multisite support. This plugin is more or less a development tool for defining your own custom file access rules.</p>
<p>For nginx you will need to modify the config file as nginx does not handle .htacess files. Add the following code:</p>
<pre><code>location ~ "^/wp-content/uploads/(.*)$" {
    rewrite ^/wp-content/uploads(/.*\.\w+)$ /index.php?jvm_protected_media_file=$1;
}
</code></pre>
<h3>Hooks</h3>
<p>Without a custom hook all file access will be disabled. The user will see the 404 page for all requested files. Adding a hook is needed to handle your own file access rules. A simple example that could go into your functions.php:</p>
<pre><code>function my_file_access_rule($file_info) {
    // Implement your own logic here
    $userHasAccess = true;

    if($userHasAccess) {
        // Send the file output if users has access to the file
        JVM_Protected_Media::send_file_output($file_info['path']);
    }
}

add_action( 'jvm_protected_media_file', 'my_file_access_rule');
</code></pre>
<p>The jvm_protected_media_file action has one parameter with the following file information:</p>
<pre><code>Array
(
    [id] => id_of_the_file
    [url] => full/url/to/your/file
    [path] => full/path/to/your/file
    [is_resized_image] => bool (true if the requested file is a image thumbnail or resized version of an image)
)
</code></pre>
<h3>Actions</h3>
<p>Available actions:</p>
<ul>
<li>jvm_protected_media_loaded (fires as soon as the plugin is loaded)</li>
<li>jvm_protected_media_file (fires when a file is requested)</li>
</ul>
<h3>Functions</h3>
<p>To send the output of a file to you can call:</p>
<pre><code>JVM_Protected_Media::send_file_output($fullPathToFile)
</code></pre>

<p>Copy protect PDF. No other WordPress plugin can securely protect PDF from all copy because they only use JavaScript and HTML. The difference with CopySafe plugins is that they provide an “interface” to use a more robust solution that can interact at system level which is where copy needs to be actioned.</p>
<p>This plugin enables the use of copy protected PDF documents in WordPress posts and pages. The resulting embedded PDF object is supported in the ArtisBrowser on all OS including Windows, Mac, iOS and Android mobile.</p>
<p>CopySafe PDF provides the most secure copy protection for PDF both online and offline. This plugin displays PDF created for use online and when domain lock is applied, the PDF file cannot be displayed from anywhere else. With PDF now bound to your web site, you are free to apply DRM rules to control access to the page via your CMS member controls. The ArtisBrowser reports the user’s unique computer signature so that you can convert WordPress into a fully fledged DRM Portal by adding a new field to your member’s table and some script to compare current ID with the one already assigned.</p>
<ul>

CopySafe PDF Protection – Copy Protect PDF

@expensive brick
What a pointless review if not to defame a free service that is provided for users of Copysafe PDF. Yes, this WordPress plugin is provided for free, and yes you need the Copysafe PDF software to take advantage of proper protection. Otherwise you will find that this plugin works perfectly and that you can upload PDF created from the demo version of their software. All you need to do is learn to read and follow the instructions.
Re expense, have a look around and see if you can find a comparable PDF protection solution for less than 10 times the price of this one.



There is no better alternative
