With wide deployment(s) of flash drives being used in various environments (secured or otherwise), the issue of data and information security remains important. The use of biometrics and encryption is becoming the norm with the need for increased security for data; on-the-fly encryption systems are particularly useful in this regard, as they can transparently encrypt large amounts of data. In some cases a secure USB drive may use a hardware-based encryption mechanism that uses a hardware module instead of software for strongly encrypting data. IEEE 1667 is an attempt to create a generic authentication platform for USB drives. It is supported in Windows 7 and Windows Vista (Service Pack 2 with a hotfix). 
Over the last year, from the first half of 2012 to the first half of 2013, compensation among all occupations combined grew just percent, partially reversing the percent decline from the first half of 2011 to the first half of 2012. Across occupational categories there was little variation (ranging from growth of percent over the last year in construction and service occupations to a percent increase in installation and maintenance). However, this modest acceleration in real compensation stems partly from a deceleration of inflation that is unlikely to continue.
