Answer 1

You could try something like this.
/**
* Allow access to own content only
*/
function my_authored_content($query) {
//get current user info to see if they are allowed to access ANY posts and pages
$current_user = wp_get_current_user();
// set current user to $is_user
$is_user = $current_user->user_login;
//if is admin or 'is_user' does not equal #username
if (!current_user_can('manage_options')){
//if in the admin panel
if($query->is_admin) {
global $user_ID;
$query->set('author', $user_ID);
}
return $query;
}
return $query;
}
add_filter('pre_get_posts', 'my_authored_content');
This will only let admin and the author see the content.
You can either add it to the main functions file or turn it into a plugin.

Answer 2

To create it as a plugin:
Create a new file
add the code from here: http://pastebin.com/rfMLM0BU
save it as my-authored-content.php
upload it to your plugins directory.
Hope this helps you! :-)

For me works this:
function mymo_parse_query_useronly( $wp_query ) {
if(isset($wp_query->query_vars['post_type']) && $wp_query->query_vars['post_type'] == 'attachment'){
if ( !current_user_can( 'level_5' ) ) {
$wp_query->set( 'author', get_current_user_id() );
}
}
}
add_filter('parse_query', 'mymo_parse_query_useronly' );
I use this for uploaded profile picture for the user profile in front end
