Escrow enables LuxSci SecureLineTM users to send secure email messages to anyone with an email address.

  1. The recipient gets a notice of the waiting message in his/her INBOX
  2. S/he clicks on a link in the notice to get to the Escrow Portal
  3. S/he either answers a question or enters a password for identity verification
  4. The recipient then can access the message, download it, reply, save it, and delete it.

The message remains available to the recipient until s/he deletes it, until it expires (you as the sender determine when that happens), or until the sender retracts it.

Verifying Recipients

The Escrow service verifies the identity of the recipient before it provides access to the waiting message. This is to help ensure that only the intended person can access the message content.

There are two methods of verification available: "SecureSend Login" and "Question and Answer".

Verification by Question and Answer

When a recipients tries to access an Escrow message:

  • S/he is prompted to answer a security question provided by the sender
  • If s/he can answer the question correctly, s/he is taken to view the message

Use of "Question and Answer" requires the sender to prepare the questions ahead of time and ensure that the recipients will be able to answer them. Recipients must be able to answer the questions and they may be different for different messages.

Verification by SecureSend Login

The first time a recipient tries to access an Escrow message:

  • S/he is taken through the steps to register for a SecureSend Account
  • This includes sending a confirmation email to his/her email address
  • S/he clicks on a link in the confirmation email to verify that s/he has access to that email account
  • S/he is taken to view the waiting message

Subsequently, when the recipient tries to access an Escrow message, s/he is simply prompted for his/her current SecureSend password.

Using "SecureSend Login" requires no setup on the part of the Sender, no special communication between the sender and recipient, and a couple of extra steps to access the first message. However, access to subsequent messages and messages from multiple senders is simplified over "Question and Answer".

SecureLineTM Escrow Features for Senders

LuxSci SecureLineTM Users sending messages via Escrow:

Meets HIPAA Requirements
Optionally protect email message subjects
Most secure email portal pick up services use the actual email subject in the email sent informing people of the waiting message. This is very usable, but risky if your users may enter sensitive information in the subject. With SecureLineTM Escrow, you can optionally specify a fixed subject, such as "You have been sent a secure email message," for these messages, mitigating this risk.
