Retrieve hidden field in form_for

I want to retrieve hidden field in a form for. Here is my form :

<%= bootstrap_form_for :cvs do |f| %>
    <%= f.text_field :nom, label: "Nom du nouveau CV", :required => true %>
    <%= f.hidden_field :cvuse, :value => params[:user] %>
    <%= f.submit class: "btn btn-primary"%>
<% end %>

When I check my server logs I could see my variable passed :

Started POST "/cvs" for 127.0.0.1 at 2015-08-31 14:30:36 +0200
Processing by CvsController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"someCrazyKey", "cvs"=>{"nom"=>"dd", "cvuse"=>"1"}, "commit"=>"Save Cvs"}
Unpermitted parameter: cvuse

Do you know how I could retrieve this variable cvuse. just for precision this form execute the create method in my controller.

Rails 3 without strong params:

params[:csv][:csvuse]

Rails 4 with strong params:

def csv_params
  params.require(:csv).permit(:csvuse)
end

def create
  csvuse = csv_params[:csvuse]
end
