How to Send or Receive Files Securely with LiquidFiles


Admin IT offers the LiquidFiles service as a way to send documents securely as opposed to email attachments. Documents containing sensitive data, also known as Personally Identifiable Information or PII data, should always be sent securely and not as email attachments. The UC Davis Campus IT Security department has identified varying levels of PII data classification. Read their PII classifications here.

Any documents containing any of the following information that needs to be transmitted must be done via secure transmissions such as through LiquidFiles. Documents containing PII data cannot be attached to an email:

  • Social Security number
  • Driver's license number or California identification card number
  • Account number, credit or debit card number, in combination with any required security code, access code, or password that would permit access to an individual’s financial account
  • Medical information
  • Health insurance information

    Where they can send the Requested Files back to the requester.

    A couple of things to note:

    • The Link is one time use only and will expire when the files have been delivered.
    • The user that received the link does not need to register or do anything other than click on the link in the email. Since they received the email with the link, we know that the email address is valid.
