Security For Portable Data Storage media

Abstract: Due to the emergence of smart handheld devices, the portable storage market environment is rapidly changing. With the proliferation of these removable media devices there are many problems where personal identifiable information data and corporate confidential affairs are leaked to the public in case of loss, theft, or capture of the portable device. Various kinds of authentication solutions are developed to protect the confidential information against unauthorized access. But after some research, we found that these solutions which were developed to mitigate these threats; have some serious problems as some of them have insecure environment The main objective of this paper is to present the design of an efficient, real-time system to a secure digital flash memory card via hardware. Accordingly, this paper presents a secure user authentication scheme to bypass authentication; enabling the user to block unauthorized access to an entire SD card by establishing a required user authentication for read/write access. To protect the contents from piracy or misuse we provide an application that will encrypt and decrypt the content according to our encryption scheme. Hardware and software security measures implemented in the system defeats any attempts of unauthorized access and maintains ultimate control to protect data and prevent theft. Considering the pitfalls ofexisting security hardware modules we have proposed easy- steps solution which is suitable for most Oss.
