Having been involved in the IT industry for 30 years, Derek has seen the change in perception from what personal computers used to seem safe because people used them in the privacy of their homes, to today when it is easy to trace our activities online. He also notices the courtships and illicit affairs are accelerated by technology.

He also unpacks retro sex, which is a phenomenon of reconnecting with someone you haven't seen in 10-30 years and hooking up with them after reconnecting digitally.

In his career of going through 1000s of phones and devices, he has seen virtually everything.

In digital forensics, everything leaves a trace. You may not be able to recover deleted info but you can usually find a trace.

"If someone is engaging in a lot of misconduct, even if it's not infidelity if it's gambling or poor habits... even if they try to cover their tracks, there is going to be some information."

Derek shares a story about a man who was using prostitutes and found a creative way to issue payment. The women he associated with all had amazon wish lists, and he would purchase the items off their list so the only thing he looked guilty of was having a bad amazon habit.

One of the areas that they look at a lot is video game communities. People who play games online can develop just as strong as a relationship as those in real life. If you're a parent who thinks your kid is too young for a phone, but they have a video game platform with an internet connection and camera, you may need to take a closer look.

Derek talked about online privacy, and what happens when privacy is compromised.
