Title: Junko Sasaki: Innovator in Data Transmission and Program Authorization

Introduction

Junko Sasaki is a prominent inventor based in Kawasaki, Japan. She has made significant contributions to the fields of data transmission and program authorization. With a total of 3 patents to her name, her work has had a notable impact on technology.

Latest Patents

One of her latest patents is a program use authorization method. This method involves preparing first and second codes specific to each program. The first code is encrypted to generate a first encrypted code, which encrypts the second code to create a second encrypted code. The second encrypted code is then stored in a memory medium. An install key, which the user must input, is created by combining the first and second codes. To authorize installation, the first code in the input install key is converted into the first encrypted code in the medium. A computer, on which the program is installed, obtains the first encrypted code and generates the second encrypted code by encrypting the second code contained in the install key based on the first encrypted code. The computer then reads the second encrypted code stored in the medium and compares both codes to provide installation authorization.

Another significant patent by Junko Sasaki is related to the control of command transmission and reception in a data transmission device. This data transmission system includes first data terminal equipment, a first modem, a transmission line, a second modem, and second data terminal equipment connected in series. To send a control command to the second modem, the first modem interrupts the path of transmission data from the first data terminal equipment to the transmission line. The first modem then sends the control command to the second modem. When the second modem detects the control commands, it interrupts the path of receiving data from the transmission line to the second data terminal equipment to prevent a deadlock in the data transmission system.
