Java card based security application module

The amount of data we have is getting higher along with the growing technology.Internet and other digital media make it possible to share data faster and easier, as amanner of this, it is needed to protect some data. There are wide variety of softwareon the market specialized on data protection, but it is proven by research that themost powerful technique is using an external hardware module.The smart card is one of the most feasible hardware which can be used as suchmodule. Java cards would be the best choice, because of the ability of applicationdevelopment in it and also it is possible to get engineering samples with smallamounts.This study gives information about infrastructure of such a personal securityapplication module.
