Introduction

Shigeyuki Kawana is an influential inventor based in Tokyo, Japan, known for his substantial contributions to the field of technology and IC card systems. With a remarkable portfolio of seven patents, Kawana has made significant strides in addressing security concerns related to data integrity and access management.

Latest Patents

Among his recent innovations, Kawana has developed an IC card system designed to prevent unauthorized data alteration. This innovative system incorporates an IC card that internally stores two different Personal Identification Numbers (PINs). The authentication process involves collating these PINs, which determines the operational status of the IC card. A successful match of the first PIN allows data input, while a match of the second PIN enables data transfer. This dual-layer security effectively safeguards important data when handled by multiple users, ensuring that alterations remain authorized and controlled.

Another noteworthy patent concerns the intricacies of the IC design itself. It details a process where an IC, featuring EEPROM technology, is fabricated on a semiconductor wafer. The design includes exposed address and data pads that allow for comprehensive testing of the IC. Following successful tests, the wafer is diced into IC pellets, after which the pads are disconnected to enhance security. Finally, these pellets are wire-bonded, sealed, and integrated into an IC card body, forming a crucial component of many electronic systems.
