Queensland police fear criminals will use high-tech encryption software on Microsoft's new Windows 7 to bury pornographic images and files deep within computer networks. “"My understanding is that Windows 7 has more encryption functions in it, which is problematic for us [police]." The programs BitLocker, which was featured in Windows Vista, and BitLocker To Go - were designed to help users encrypt files easily. "All that needs to be done by the user is to right-click the device in the Windows 7 operating system and pick the BitLocker option from the menu that is popping up," Microsoft says on its website. While Microsoft affirms the "unbreakable" nature of its new encryption technology, the company disputes claims that criminals would successfully use the programs to lock out police and other law-enforcement agencies,” said Detective Superintendent Brian Hay from Queensland's Fraud and Corporate Crime Group.
