The state's health insurance exchange transmitted pregnancy and domestic abuse data during a marketing campaign.

Abstract:

Excerpt:

In addition to demographic information including gender, the site also shared details with LinkedIn when visitors selected their ethnicity and marital status, and when they told coveredca.com how often they saw doctors for surgery or outpatient treatment.

LinkedIn, like other large social media firms, offers a way for websites to easily transmit data on their visitors through a tracking tool that the sites can place on their pages. In LinkedIn’s case, this tool is called the Insight Tag. By using the tag, businesses and other organizations can later target advertisements on LinkedIn to consumers that have already shown interest in their products or services. For an e-commerce site, a tracker on a page might be able to note when someone added a product to their cart, and the business can then send ads for that product to the same person on their social media feeds.
