Penn State College of Information Sciences and Technology joined up with Unisys to initiate digital footprint education for the area high school students. https://ist.psu.edu/newsevents/?pageID=736&HeadlineID=2088 It makes sense that top Penn State students in the college of IST would have an effectively persuasive persona for high school students to start taking their digital footprint more seriously.
Holton Arms School website adds a comment to parents related to the digitatl footprint of their children. Education of parents on this issue, seems another important part of the increasing footprint awareness. https://www.holton-arms.edu/uploaded/technology/2010-2011_Student_Laptop_Program-_Returning_Students.pdf
This site provides a good visual of just how pervasive a digital footprint is http://www.skuggen.com/2010/05/how-to-clean-up-your-digital-footprints/
The view you are presenting about digital footprints is only 1/3 of the story.
What you generate about yourself – as per your diagram, is the part of your digital footprint that you are in control of.
What others say about you is another 1/3 of your digital footprint and this is not in your control
What data says about you and your interactions makes up the final 1/3
together, these data sets make up your digital footprint
