The monitoring system is intended to help the police ensure that
people convicted of hooliganism at football games honor the terms of
their release, and stay away from games. The Dutch police are known
for their use of unconventional means to combat the rising soccer
violence.
After a lengthy period of trials the police chose the Persay system
The system is a step-up on an electronic system already in use in the
Netherlands. It works by randomly calling convicted hooligans at home
during soccer games. The program can identify their voices. It can
support an unlimited range of languages and dialects, as well as
accents, overcoming background noises and ignoring natural
fluctuation in voice.
Persay technology is already used to keep track of people under house
arrest in several countries worldwide, including the United States,
England, New Zealand, and Spain.
Recently the U.S. Homeland Security system adopted the Persay
technology to ease life for immigrants, instead of reporting in
person to visa offices, they can phone in and be identified
bioemetrically.
Persay's solution uses the biometrics of the speaker's own voice and
speech characteristics to authenticate speaker identity.
The Dutch Justice Ministry recently approved the use of Israeli
company Persay's biometric voice verification and authentication
systems to help keep out hooligans from soccer matches.
