About Dropbox

The Caltech SURF Payroll Dropbox allows you to securely send files to Caltech Student-Faculty Programs.

After 96.0 hours, Dropbox will delete your uploaded file, and the URL will become invalid.

Conceptual design

We made Dropbox to satisfy the following requirements:

• Should not require the use of a special client.
• Should be unattractive as an illicit file distribution center.
• Should not require people to have local accounts or to authenticate at all.
• Should be usable under all operating systems.
• Transferred files should be accessible only to the intended recipient.
• Should clean up after itself.
