Locked IP

When you send email with INTERDUBS then you can add a tracking code to the link in the email. This allows the connection of email recipients and page visitors. This information can for instance be displayed in the log screens.

It is possible to lock the recipient of an email to use the same IP address for visits. This option can be found on the second email screen below the text of the actual email.

When the person clicks on the link in the email and opens the page for the first time this system will note the IP address that the visitor uses.

Future visits of this link will have to originate from the same IP address. Should the same link sent in that email get accessed from a different IP then the visit will be declined.

Each email gets a unique link. You still can have multiple visitors for a page. But people can not forward links. That link can only be used on that IP address.

Limitations

Currently the lock ip feature does not automatically disable the client forward screen. Lame - but we are looking to gather some feedback and experience and will finish this accordingly.

People working at the same company often share an IP address that they outside world gets to see. In these cases people CAN share a link among each other as long as the originating IP is the same. eG they do so within their office.

Sometimes IP addresses change. In these cases the same person will no longer be able to access the content that they used to.

The IP lock is done in a matter that will prevent 99% of all people from being able to forward matters. It is possible that skilled people craft their way around this feature. It is conceivable that they circumvent the lock. It is not as secure as other INTERDUBS security measures.
