Get Ready to Expose Yourself: Deep Packet Inspection is Back
According to the Wall Street Journal, profiling methods for Internet users are coming back and are more intrusive than ever. Advertisers may begin to use a technology known as “deep packet inspection,” which reads and analyzes the raw packets of your personal data that travel across the internet.

With the information they gather online, advertisers target ads directly to you based on your online history. Have you ever felt like all the advertisements on sites were for services you have used or would use? Well they often are, and with deep packet inspection, they will be even more specific! The use of this technology gives advertisers the ability to show you ads based on extremely detailed information.
