5 Who Uses Webcams?

6 How Do People Spy with Webcams? Many Trojan horses and other malware programs can be used to take remote control of a computer and turn on webcams unnoticed According to Mike Geide, senior security researcher at cloud security company Zscaler, "there are several exploit kits out there that include rootkit functionality that allow (people) to interact with the operating system however they want, and that includes turning on specific services or running applications in the background that would include applications to report Webcams, record audio, or turn on a built-in internal microphone.” “Games” that mislead users into clicking a link that can remotely control a user’s webcam and microphone Some security software cannot counter or acknowledge the hijacking I SEE YOU!

7 Recently in the News Recently, the School District of Lower Merion in Ardmore, Pennsylvania, was alleged of violating a student’s privacy via Webcams. The district issued laptops to high school students as part of a technology initiative, and did not notify families the laptops were equipped with Webcams that could be turned on remotely.

8 Two Sides of the Story Reasons People Agree with the Law Suit: Reasons People Disagree with the Law Suit: Feel violated and uninformed Feel actions were unconstitutional Feel School district abused its power Feel privacy has been compromised See no benefit of a class action suit Concern over financial impact school will face (will lead to cutbacks, layoffs) Feel teacher had good intentions * Although most parents disagree with the school district using webcams to spy on students, most parents do not want a lawsuit filed. Nearly 500 parents from the district have organized a petition opposing the lawsuit. These parents say they are angry about the webcams, but are concerned about the financial impact of a class- action settlement. *

9 Why I am Against School Districts Using Webcams to Spy

10 What is Being Done at Lower Merion School District? Since the national coverage of this story, as well as the parental and community outcry, the school district has disabled its remote monitoring capabilities al together. A motion was filed, and presumably will pass, that is designed to keep any pictures that were gathered through the district’s accessing of students’ laptop computers out of the hands of the public. Carol Cafiero, one of two Lower Merion school officials responsible for using the technology, has been under FBI interrogation, with a deposition scheduled Friday, April 9. Family of student who was spied on and falsely accused of selling and using drugs are still pushing for their potentially devastating lawsuit against the school district. Many parents and community members are organizing to protect the teacher and the school district fearing the financial burden a court case would cause this school, which happens to be facing another lawsuit in the context of racial discrimination.
