How can I have my abstract at the titlepage in LaTex?

Question

My LaTex file:

\maketitle
\begin{abstract}
   For over a century, fingerprints have been an undisputed personal identifier. 
   Recent court rulings have sparked interest in verifying unique...
\end{abstract}

I would like to a similar titlepage as here.

My document class is article. This is the beginning of my file.

The abstract appears on its own page because you've specified the titlepage option to the article document class:

\documentclass[12pt,a4paper, titlepage]{article}

If you remove this option (or specify notitlepage), then the abstract will appear on the first page, together with the article title, author, and date:

\documentclass[12pt,a4paper,notitlepage]{article}

Then, if you want the first section of the article to start on a new page, you should add a \clearpage command:

\clearpage
\section{First Section}
