Delete Files So Securely Even Forensic Analysts Can't Find Them Don't Just Erase Messages or Pictures -- Terminate Them Eric Grevstad
Mon 10/14/02 -- Whether you're handing your old PC down to a coworker or about to sell, give away, or throw away a former home computer, the files and programs on its hard disk are still readable by snoops -- even after you delete them. Iolo Technologies LLC's new System Shield wipes, rewipes, and scours away all traces of documents, e-mails, or images that you intended to remain private, preventing identity theft, security attacks, and corporate espionage.
The Personal Edition ($40) blocks software-based file-recovery tools such as undelete utilities and sector, hex, and disk editors; it supports all versions of Windows from 95 and NT through XP and the FAT, FAT32, and NTFS file systems. Besides emptying the Windows Recycle Bin and overwriting deleted files, it purges the files' names from directory structures.
System Shield Professional Edition ($130) adds special functions to meet all published military requirements for secure data disposal, and even protects against forensic hardware-based recovery techniques such as magnetic field residue tracing and tunneling electron microscope inspection.
