Secure USB flash drives protect the data stored on them from access by unauthorized users. USB flash drive products have been on the market since 2000, and their use is increasing exponentially. As both consumers and businesses have increased demand for these drives, manufacturers are producing faster devices with greater data storage capacities.An increasing number of portable devices are used in business, such as laptops, notebooks, universal serial bus (USB) flash drives, personal digital assistants(PDAs), advanced mobile phones and other mobile devices.
Companies in particular are at risk when sensitive data are stored on unsecured USB flash drives by employees who use the devices to transport data outside the office. The consequences of losing drives loaded with such information can be significant, and include the loss of customer data, financial information, business plans and other confidential information, with the associated risk of reputation damage.


Compromised systems:The security of encrypted flash drives is constantly tested by individual hackers as well as professional security firms. At times (as in January 2010) data on flash drives that have been positioned as secure were found to have a bug that potentially could give access to data without knowledge of the correct password.
Flash drives that have been compromised (and fixed) include:
SanDisk Cruzer Enterprise
Kingston DataTraveler BlackBox
Verbatim Corporate Secure USB Flash Drive
Trek Technology ThumbDrive CRYPTO
All of the above companies reacted immediately. Kingston offered replacement drives with a different security architecture. SanDisk, Verbatim, and Trek released patches.
