If you work away from home or the office with sensitive information, you may be concerned about privacy and leaving traces of what you are doing, or leaving important documents on a temporary computer.

Security company Mobiu’s answer to this is the Smart Key, a device that combines the Pin security you might find on a bank card with online storage of documents to bring convenience and peace of mind when working from an unfamiliar location.

The device comes in the form of a 1GB USB memory key and offers 1GB of online storage by default. When connected it requests the user to enter a pin to grant access to a screen from which files can be accessed.

Backups can be created from relevant folders on your computer’s hard disk and when documents are changed on your usual computer they can be refreshed to bring the online copies up to date.

It’s also possible to save multiple versions of your documents so if you make a change you don’t like you can go back. There is no restriction on the size of each file or the number of files that can be uploaded.

When you access a document from a different computer it is temporarily downloaded to the storage on the Mobiu device while you work on it. The Mobiu interface also offers dedicated, secure software to handle common documents.

A word processor, spreadsheet and presentation package are included and offer a wide range of features as well as full support for common files such as those created by Microsoft Office.

It also includes a web browser, archive software and a PDF reader so a wide range of documents can be retrieved and modified without any trace being left on the host computer.

You can even invite other Mobiu Smart Key owners to access your storage at the same time, which makes it an effective way for business users to work on group projects.

The Mobiu Smart Key is very effective if you need security for your documents while on the move. It’s easy to use and offers all the tools required.
