Options for Sharing Confidential Data

• Cornell’s Dropbox service, dropbox.cornell.edu, is approved for sharing confidential information, since it is owned by Cornell and designed with confidential sharing in mind. Also, remember that the files you download from Cornell’s Dropbox can be saved in hidden cached areas on your computer if you’re not careful.
• Limited direct access to the approved location where the data is stored may be another acceptable method. Contact your local technical support team or the IT Service Desk for additional assistance.

Before using any IT tool to send, store or share institutional information, review the Regulated Data Chart.
