Print bibliography, anonymising the authors

I have a pretty weird request. I would like to print a bibliography (using biber and biblatex) but I'd like to remove all the author information. That is, I'd like to print a bibliography, without identifying any of the authors. What's the easiest way to do that?

The following removes all name fields from all .bib entries

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=numeric, backend=biber]{biblatex}

\DeclareSourcemap{
\maps[datatype=bibtex]{
\map[foreach=setnames]{
\step[fieldset=\regexp{\$MAPLOOP}, null]
}
}
}
