4.1 Ethical and Social Issues Around Data Collection

1. Exam Points

• Algorithmic bias may create unfair outcomes for certain groups of users. (identify bias)
• Programs/application may put personal privacy at risk. (identify risks – non-private properties are at risk).
• When design a class, use the private keyword instead of the public keyword properly for protecting privacy.

2. Knowledge Points

• (1) Protect privacy
  • When using a computer, personal privacy is at risk.
  • When developing new programs, programmers should attempt to safeguard the personal privacy of the user.
  • You may use the private property where necessary to protect privacy.
  • Example

    class User{
            private String username;
            private String password;
            // public method implementation not shown
    }
    

• (2) Algorithmic Bias
  • Algorithmic bias describes errors in a program that create unfair outcomes for certain groups of users.
  • Ex. collect data only from premium users for developing new features.
  • Bias may rise when programmers manipulate data in collections to retrieve information using methods.
