Abstract: A condition data acquirer acquires first data (condition data) of a plurality of items related to a test process of a plurality of semiconductor chips. A test result acquirer acquires second data (test result data) indicating test results of the plurality of semiconductor chips in the test process. A decision tree generator generates a decision tree with each item of the condition data as a feature amount and the test result data as a target value. An analysis result outputter outputs, as an item having a large influence on the test results, information of a feature amount having a relatively high importance in the decision tree.

Abstract: A condition data acquirer acquires first data of a plurality of items related to a test process of a plurality of semiconductor chips. A test result acquirer acquires second data indicating test results of the plurality of semiconductor chips in the test process. In a region in which a plurality of items of the condition data are arranged on one axis and a plurality of values of the respective items is arranged in a direction orthogonal to the axis, a graph generator generates a graph image in which corresponding values are connected by lines over the plurality of items for each group of a plurality of semiconductor chips having the same test environment. The graph generator changes a form of the lines for each group in the graph image according to a ratio of the semiconductor chips whose test results have been failed in each group.

Abstract: An authentication terminal comprising an authentication apparatus authenticating an authentication subject, an artifact operating in accordance with an input signal and a signal processing section is provided. When an authentication result in the authentication apparatus is passed, the signal processing section inputs an input signal without including information of the authentication subject in the artifact and outputs an output signal in accordance with an operation result of the artifact as the authentication result.

Abstract: An authentication system comprising an authentication terminal and an authentication server is provided. The authentication terminal comprises an authentication apparatus authenticating an authentication subject, an artifact operating in accordance with an input signal and a signal processing section inputting an input signal without including information of the authentication subject designated by the authentication server in the artifact and outputting an output signal in accordance with an operation result of the artifact as an authentication result when the authentication result in the authentication apparatus is passed. The authentication server authenticates the authentication subject based on the output signal.
