Avoid duplicate file uploads - Rails 4

In Rails 4.0 Project, I am using multiple file upload plugin. Right now it is working via ajax request. Now, I want to avoid duplicate file upload and it should show proper validation message. Also as soon file upload page needs to refresh. How can I validate duplicate files and refresh the page?

Reference : http://hayageek.com/docs/jquery-upload-file.php#multi

Paperclip gem version is

paperclip (3.5.2, 2.3.11, 2.3.8)

In views,

<%= simple_form_for(@file, :as=>"file", :url=>create_files_path, :html=>{:multipart => true, :autocomplete=>"off"}) do |f| %>
  <%= f.input :document, :as=>:file, :label =>false, :required => true %>
<% end %>


<script type="text/javascript">
  $("#file_document").uploadFile({
   url:"<%= create_files_path %>",
   multiple:true,
   showDone: false,
   showProgress: true,
   showError:true
 });
</script>

Based on @Bjoernsen comment on MD5 digest I found this blog post which is also comparing files on S3. I believe this is also how git works using SHA-1 hashes.

Again, Thanks to @Bjoersen for pointing it out. I learnt something.
