摘要
The present invention provides a qualification screening system which is capable of performing qualification screening on a device under qualification screening using a status of information to be updated that is retained by the device under qualification screening without having to know concrete procedures or methods for updating such information. A qualification screening device estimates the status of information to be updated that is retained by the device under qualification screening from a time at which an information update program that updates the information to be updated, which is independent of update procedures or methods, was activated and update processing was last updated, and compares the information with a time of a scheduled issuance of information to be updated, retained in qualification screening condition information of the qualification screening device itself, to perform qualification screening. A common time at which information exchange was performed between the qualification screening device and the device under qualification screening is used as reference in order to perform an effective comparison using time information among devices that are not synchronized.
