A DataLock is a hardware security mechanism integrated with portable storage to provide self-contained locking and user authentication capabilities. The drive is self-secured and host independent.

[edit] Technology

The portable storage is integrated with an on-board input mechanism such as keypad used to enter a combination (like a combination lock) or a Personal identification number (PIN). When locked, a DataLock enabled storage device is invisible to its host. With the correct combination, it becomes unlocked to allow read/write access and behaves as a standard USB flash drive. Upon removal, it automatically locks.
Temper resistance is implemented using on-the-fly full disk encryption. When unlocked, all data sent to the drive is encrypted.

[edit] History

DataLock technology IP is own by ClevX, LLC. Corsair Memory was the first to manufacture and launched a DataLock-based drive named Flash Padlock to the consumer retail market at August 2007^[1].

[edit] Benefits

DataLock enabled portable storage provides a unified authentication mechanism for all content and portable applications contained within.

DataLock security is managed by the device and not the host. A DataLock drive does not depend on any host software or a specialized device driver. Once unlocked, the device is accessed as a USB mass storage device class.

Security is cross platform and host independent. Since authentication does not depend on or requires host functions, it works equally well with all operating systems that support the USB Mass Storage Class: for example Windows, Mac OS, Linux, office equipment and embedded devices.

Since no DataLock communication channel exists when locked, it is immune to brute force attack originating from its host.
