Privacy and Technology: Folk Definitions and Perspectives.

Area of Science:

• Human-Computer Interaction (HCI)
• Social Psychology
• Privacy Studies

Background:

• Existing privacy theories by Westin and Altman provide a framework for understanding privacy beliefs.
• However, these theories may not fully capture the nuances of individual differences across diverse demographics.

Purpose of the Study:

• To explore individual differences in privacy beliefs among young and older adults.
• To relate lay definitions of privacy to established privacy theories.
• To identify how age and gender influence privacy concerns.

Main Methods:

• Conducted focus groups with young adults (18-28) and older adults (65-75).
• Collected individual definitions of privacy.
• Discussed privacy perceptions across six varied scenarios representing potentially invasive situations.

Main Results:

• Both Westin's and Altman's theories partially explained privacy perceptions across age groups.
• Gender differences emerged: males prioritized personal needs/convenience, while females focused on others' rights and safety.
• Older adults expressed greater concern for spatial privacy over information privacy.

Conclusions:

• Individual differences in privacy beliefs are significant and influenced by age and gender.
• Existing privacy theories offer partial explanations but do not encompass all observed variations.
• Tailoring human-computer interaction (HCI) design to specific user populations' privacy expectations is essential.
