Maki Enterprise has released a new security solution that lets users emp0loy an iPod as a digital "key".

The new PodSmith software (OS X) employs a user's iPod as a key for security and for various synchronization features. It means users can set their Mac up in order that it can only be accessed when a user connects a pre-defined iPod to the machine.

The news emerges as analysts surf a philosophical wave that warns extensive use of iPods and other forms of hard drive may threaten data security in some companies.

PodSmith features include:

Screen lock
You can lock and unlock the screen by unmounting and mounting your iPod.

File lock
Specified folders or files can be locked by unmounting the iPod.

Files protection
Disable all applications except those you specify.

PodSmith works with any iPod model, including iPod Shuffle and requires Mac OS X 10.3 or later. The software is available for trial use from the company.
