We have all seen them, these tiny storage devices used for computers, cameras, mobile phones, MP3 players, game controllers, and more. Memory cards are known for being convenient, fast, and loaded with capacity, but just how much security do they offer? The truth is that USB memory cards are designed with what is known as “full disk encryption”, which works with computer software. As a result, only authorized people can access stored data. Unfortunately, this drive is accessible in a small number of computers. On the other hand, a type of compatible encryption software has been created to resolve the problem.

Now, many of the new memory cards are designed so the user’s identity is confirmed with biometric fingerprinting. In place of information being protected with a password, a person’s fingerprint is validated simply by using a software driver.  Additionally, some memory stick manufacturers are currently helping to control access to sensitive information by using encryption keys on the computer itself. For this to work, the memory card would need to be plugged into the USB port. Overall, SDHC memory cards, micro-sd memory cards, and others are secure. However, because these devices are small and portable, there is an increased risk of them being lost or stolen. For this reason, many larger corporations have steered away from using them and even everyday users need to be extra careful.
