摘要： PROBLEM TO BE SOLVED: To make it possible to request a signature from a signer even when the signature environment of each signer is diverse, as well as enable signing by a signer to be made under the condition intended by a signature requester.SOLUTION: If a signer is an inside user, a request of a signature on a signature server side is made to a computer which the signer uses, or if the signer is not an inside user, an inquiry is made to the computer which the signer uses to know whether use of the signature server is needed. If the inquiry is responded to the effect that the signature serve is used, the computer which the signer uses is accessed to acquire the signature environment of the signer and, if the acquired signature environment is found to be inappropriate, the acquired signature environment is normalized. If the inquiry is responded to the effect that a signature is executed on the signer side, a request of signature execution on the signer side is made to the computer which the signer uses and, if the signature environment is found to be appropriate or the signature environment has been normalized, a request is made that a signature be executed on the signature server side.
摘要翻译：要解决的问题：即使每个签名者的签名环境是多样的，也可以从签名者请求签名，并且能够由签名者在签名请求者预期的条件下进行签名。解决方案：如果签名者是内部用户，则签名服务器端签名的请求是对签署者使用的计算机进行的，或者如果签名者不是内部用户，则对计算机进行查询签名者使用它来知道是否需要使用签名服务器。如果对使用签名服务的效果进行了询问，则访问签名者使用的计算机来获取签名者的签名环境，并且如果发现所获取的签名环境不合适，则所获取的签名环境被归一化。如果询问对签名者签名的效果作出响应，则签署人使用的签名者签名执行请求被发送给签署者使用的计算机，并且如果发现签名环境是合适的或者签名环境已被归一化，请求签名服务器端执行签名。版权所有（C）2013，JPO＆INPIT
