People like to meet other people to socialize. To this end, some people use online
matchmaking services, such as “OkCupid,” to find new friends or to find a date for
a Friday night. Online matchmaking services can match one user to another user
using matchmaking algorithms. These matchmaking algorithms use information gained
about the users, e.g., from responses to a set of questions, as well personal
information entered by the users, such as location, age, sex, religion, etc. One
significant problem with such online matchmaking services is that the fields in
which users enter personal information are open-entry fields, which enable users to
enter personal information that is either exaggerated or misrepresented.
