Is the transfer between JotForm and Google Drive secure?

If I have a user upload confidential information via a pdf and have my jot form set with an encryption code to review submissions, will I have issues with the pdf being auto loaded to a Google Drive folder upon submission?

In other words is the transfer between JotForm and Google Drive secure? How is it secured?

The Google Drive integration is using SSL certificated connection. These communications are encrypted to prevent snooping by a 3rd party. The form uploads are automatically sending to Google Drive submission folder. If you are sure about the Drive folder is private, you can feel relaxed about the data security.
