Abstract

Summary of the Invention Even if high-toughness encryption technology is used, it is readable in theory. It is because data is included in a single portable storage device. Therefore if the data is encrypted, it is not secure to carry with the device. And it takes time and labor for data protection not only to encrypt data, but also to decrypt it. This invention offers a function managing data I/O using physical structures and shapes. The core idea of this invention are the following two points: 1) The portable storage device is physically divided like tally, and its data read/write/erasure is controlled by combinations of them. 2) The portable storage device doesn't divide physically like the tally, read/write/erasure is controlled by the rearranged pattern such as Combi-Bolt or Rubik's Cube.
