Discussion 1: Many people believe that the use of biometrics is an invasion of privacy. For example, an eye scanning device records the inner structure of a person's eye and stores that image in a database. Critics worry that databases of human traits used to maintain corporate security may actually pose a privacy threat to individuals, if such data were used in other ways. In your view, are such concerns justified? Why or why not?

Assignment 1: Some common biometric techniques include:

1. Fingerprint recognition

2. Signature dynamics

3. Iris scanning

4. Retina scanning

5. Voice prints

6. Face recognition

Select one of these biometric techniques and explain the benefits and the vulnerabilities associated with that method in 3-4 paragraphs.
