Understanding Data Brokers and Personal Information Cross-Triangulation
Introduction
Data brokers are companies that collect, analyze, and sell personal information about individuals from various sources. This information can be used to create detailed profiles that include sensitive data such as home addresses, purchasing habits, social connections, and more. The practice of cross-triangulation involves combining data from multiple sources to infer additional details about individuals, potentially compromising privacy.
How Data Brokers Collect and Use Personal Information
1. Sources of Data Collection
a. Public Records
- Data brokers access public records such as property deeds, voter registrations, and court documents to gather information.
b. Online Activity
- Browsing history, search queries, and social media activity are tracked through cookies and web beacons.
c. Consumer Transactions
- Purchase history from retailers and e-commerce sites is collected, often through loyalty programs.
d. Surveys and Contests
- Information provided by individuals in surveys, contests, or sweepstakes can be aggregated and sold.
e. Third-Party Data Sharing
- Companies may share customer data with data brokers, including information from apps and services used by individuals.
Cross-Triangulation and Privacy Risks
Cross-triangulation involves combining data from different sources to create comprehensive profiles. This process can reveal sensitive information, including:
1. Home Addresses
- Example: By analyzing property records, social media posts (e.g., photos tagged at home), and delivery addresses from online purchases, data brokers can accurately determine an individual’s home address.
2. Social Connections
