A lecture on "Forensic science, biometrics and speaker recognition -- An introduction"

On this day I gave a two-hours lecture on "Forensic science, biometrics and speaker recognition -- An introduction". Around 35 students joined the class. There were lots of questions and discussions coming from the students related to all three topics, forensic science, biometrics and speaker recognition.

In the first hour, I finished my presentation. In the second hour, the students were divided into small groups containing 4--5 persons. I ask them to imagine: What if they are a biometrics expert and they are about to make a biometric system. What kind of systems will they build? 

Here are several interesting answers from the students: 

1. Fingerprint recognition for attraction ticketing in theme parks, 

2. Handwriting recognition for the students joining the national admission test for universities in Indonesia to capture cheaters, 

3. Facial recognition for smartphone (something that's already exist, I believe), 

4. Multi-modal recognition (fingerprints, iris, speech and/or facial images) for citizen identification in the national election, 

5. Iris, speaker or face recognition for access control at important buildings and/or rooms (this idea is not new, there are many examples found in sci-fi movies or drama),  and 

6. Biometrics (any kind) to access the information related to personal health track record.
