Question: Given the following context:  Mike Regan is a self-made aviation tycoon who lives in a state-of-the-art smart house full of modern technology with his wife Rose and 17-year-old daughter Kaitlyn. Mike's company is developing an app called "Omni Jet" which will increase business while the company raises much-needed financial capital with a stock offering. However, it requires U.S. Securities and Exchange Commission approval. At the company, Mike meets Ed Porter, a 28-year-old information technology consultant and calls him to fix his home's Wi-Fi signal, which his daughter complains is slow. Porter also upgrades the Global Positioning System in Mike's car and claims that he also worked at the National Security Agency and had taken part in a military exercise in Kandahar. Porter meets Kaitlyn and starts a relationship with her through social media, but Mike fires him after Kaitlyn invites Porter into the house; this ends his promising career at the company. Devastated, Porter begins to remotely access Mike's private data and his house as he covertly monitors them through the security cameras and devices all over the house. He also spies on Kaitlyn and secretly records her masturbating in the shower. Porter sends fake emails to Mike's clients and the SEC, threatening the company's survival. He also takes full control of the house's technology, which leaves the family terrified. He uses a spoof email to send Rose fake mammogram results, saying that she tested positive for breast cancer. Rose is extremely distressed, but her test results were actually negative according to her attending physician. After Mike becomes aware that Porter has done this, he attacks Porter and threatens to kill him if he does not stay away from his family.  answer the following question:  What is the last name of the person who records someone masturbating in the shower?
Answer:
Porter
