How do I securely transmit data like feedback from a client's machine? When I use an e-mail address with authentication they can compromise my account however non-authenticated sending is not allowed due to possible spam abuse and impersonation. Also SMTP could be blocked so it's not 100% reliable.

Another way would be to upload data onto my webserver using FTP but again, they will be able to compromise my FTP credentials.

I'm out of ideas, how is this supposed to be implemented in an easy way with proper security measures against exposing your credentials or not using any? I like the e-mail idea but it doesn't seem directly feasible.

    Why would they use **your** credentials? Why not create credentials unique to the client? – Brett Walker Jun 15 '15 at 13:30
  • @BrettWalker: I only have 1 FTP account because it's a free hosting service... Garry: How does this solve the problem? I still have to include credentials – BullyWiiPlaza Jun 16 '15 at 09:19
  • You cannot create your own FTP Server? If you want to receive data from many clients securely then you need to have more control of the receiving point. – Brett Walker Jun 16 '15 at 11:18
  • @BrettWalker: Well, I don't know. I'm using `Cuccfree` if that matters. Can something good be done with this in term of sending and receiving the data? – BullyWiiPlaza Jun 16 '15 at 16:39
