Preeti celebrated her birthday with her family. She was excited to share the moments with her friend Himanshu. She uploaded selected images of her birthday party on a social networking site so that Himanshu can see them. After few days, Preeti had a fight with Himanshu. Next morning, she deleted her birthday photographs from that social networking site, so that Himanshu cannot access them. Later in the evening, to her surprise, she saw that one of the images which she had already deleted from the social networking site was available with their common friend Gayatri. She hurriedly enquired Gayatri "Where did you get this picture from?" Gayatri replied "Himanshu forwarded this image few minutes back". Help Preeti to get answers for the following questions. Give justification for your answers so that Preeti can understand it clearly.
How could Himanshu access an image which I had already deleted?
Himanshu could have downloaded or saved the image on his device before Preeti deleted it from the social networking site. Once someone downloads or saves content shared with them, they possess a local copy that remains unaffected even after the original uploader deletes it from the platform.
Can anybody else also access these deleted images?
Yes, anybody else can access these deleted images if the saved copy is shared with them. Since Himanshu had already saved the image, he could forward it to others like Gayatri. Any person with whom the image is shared can view and further share it.
Had these images not been deleted from my digital footprint?
No, the images were not completely deleted from Preeti's digital footprint. A digital footprint refers to the data traces we leave online. Once content is uploaded and shared, copies can be made and circulated by others. Even after deleting from the original platform, the image continues to exist in the digital world through copies saved and shared by others, making complete erasure impossible.
Explanation
This case study illustrates the concept of digital footprint and the permanence of online content. Students must understand that once something is shared online, control over that content is lost as others can download, save, and reshare it. The textbook uses this scenario to teach students about responsible digital behavior and the implications of sharing personal content online.
