IC Chip Authentication for Mobile Web Browsers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing terminals, such as mobile phones, face limitations in accessing IC chip data due to resource constraints, requiring users to manually enter IDs and passwords for authentication when using browsers to access content, which is cumbersome and burdensome for both users and service providers.
Innovation Solution
An information processing apparatus and method that employs an IC chip with a first application capable of reading and encrypting user data, generating signature data, and a second application that transmits this data to an information providing server for authentication, allowing browsers to access restricted content without direct IC chip access, using a common encryption key for secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a browser is used to access Web content from an information providing server, then resource constraints are addressed and Web content accessibility is improved, but manual authentication entry becomes necessary increasing operation complexity
Solution Approach 1:
The user ID is read from the IC chip in advance and stored in the terminal device before browser access is needed. This preliminary action eliminates the need for manual authentication entry when the user later accesses Web content through the browser, as the authentication information is already prepared and available.
Solution Approach 2:
The terminal device acts as an intermediary between the IC chip and the information providing server. It reads the user ID from the IC chip and automatically transmits this authentication information to the server during Web content access, mediating the authentication process without requiring direct user intervention or manual entry.
2Adaptability or versatility
If the information providing server manages multiple authentication credentials (user ID from IC chip, ID and password, subscriber ID), then authentication flexibility is improved, but system complexity increases
Solution Approach 1:
The terminal device is designed with multi-functionality to handle different authentication methods. It can read user ID from IC chip, store it locally, and automatically use it for Web content authentication. This universal capability allows the system to flexibly support multiple authentication credentials while simplifying the user experience through automatic selection and management.

AI summary
An information processing apparatus according to the present application includes a first application allowed to access the IC chip, including an IC chip in which predetermined data is recorded, an IC chip reading unit that reads the data recorded in the IC chip, and a signature data generation unit that generates signature data by performing encryption processing on the recorded data read by the IC chip reading unit and a second application not allowed to access the IC chip, including a server access unit that requests acquisition of content from an information providing server by receiving the signature data and the recorded data from the first application and transmitting the signature data and the recorded data to the information providing server that provides predetermined content.
