Hi,

I am having a debate with my work colleagues about data security on Windows Mobile Devices.  We have just finished the design and implementation of a new security package that allows users to encrypt all PIM and messaging data,including attachments, and secure it with an authentication mechansim.  As well as this you can encrypt files in a the File Browser which can be self extracting for Windows PCs or other Windows Mobile devices.  Also we have remote protection allowing you to SMS your phone and either lock it or wipe all of the encrypted data.  Sim card protection will notify a predetermined number via SMS that the SIM card has been changed, so basically you will receive an SMS from the new SIM card with the IMEI number to prove to authorities what phone account has your device.

The final feature is a virtual disk.  Basically it will appear as an encrypted file in the File Explorer.  My question to my company has been, how many people will actually use this feature.  The only data, apart from the general PIM and Messaging, I have on my phone is a stack of music and also some photos taken with the camera.  I don't want to encrypt any of that.  How many of you have important documents that would benefit from having on the fly encryption in the form of a virtual disk?  It is my belief that most people that have a Windows Mobile device are only a skip, hop and a jump away from their laptop, so there is no need for this function.

Any thoughts?
