SafeHouse provides transparent on-the-fly encryption for your notebook or desktop personal computer. Using SafeHouse, you can allocate portions of your existing hard drives to be reserved for encrypted data. SafeHouse encrypted volumes appear on your PC as another Windows drive letter. All encryption is performed automatically and transparently on the fly. You can do anything with a SafeHouse virtual drive that you can do with a normal hard drive; only that with SafeHouse, the encrypted volumes require password authentication before the files become accessible.
