摘要： The signer obtains the validity check information on the electronic certificate from the certification authority when it puts the digital signature on data and delivers the signed data, electronic certificate, and validity check information to the verifier. At this time, the certification authority creates validity check information on the electronic certificate in response to a validity check request from the signer and sends it to the signer. The term of validity of the validity check information is defined as necessary. The verifier verifies the signature and, using the validity check information sent from the signer, checks the validity of the electronic certificate.
摘要翻译：签名者在将数字签名放入数据时，从认证机构获取有关电子证书的有效性检查信息，并将签名数据，电子证书和有效性检查信息提供给验证者。此时，认证机构响应于来自签名者的有效性检查请求，在电子证书上创建有效性检查信息，并将其发送给签名者。必要时定义有效性检查信息的有效期限。验证者验证签名，并且使用从签名者发送的有效性检查信息来检查电子证书的有效性。

摘要： Certification and authentication services (electronic information signing and archiving services) are given when electronic commerce is carried out in an open network such as Internet. A system has a service supplying unit and service receiving units which are connected to one another through a communication network. In the system, the service supplying unit transmits contract information including a content of a contract to the service receiving units of the service receivers. Each of the service receiving units having received the contract information prepares one party-signed contract information in which the contract information is digitally signed by the service receiver and transmits the one party-signed contract information to the service supplying unit. The service supplying unit receives the one party-signed contract information transmitted from each of the service receiving units, synthesizes a plurality of received copies of one party-signed contract information into a single document, prepares contract information signed by the service supplier in which the document is digitally signed by the service supplier, and archives the prepared service supplier-signed contract information and transmits such contract information to each of the service receiving units.

摘要： A client-server system is provided in which access to a service by a user can properly be controlled, even if an approval by another user is required for receiving the service. First, the server 2 executes a log-in processing by using a user identifier and password transmitted from the client terminal 2, and a user control file 202. Next, the server 2 executes a service control by using a service supply request transmitted from the client terminal 1 and a service control file 42 provided with the server. When the server determines that an approval by another user is required for providing the service, the server executes the approval request to the client terminal 1 that the concerned user uses. When the reply to the approval request is affirmative, the server executes the processing in accordance with the foregoing service supply request. When the reply is negative, the server informs to the user who made the foregoing service supply request that the approval is rejected.
摘要翻译：提供了一种客户机 - 服务器系统，其中即使需要其他用户的批准来接收服务，用户可以正确地控制对服务的访问。首先，服务器2通过使用从客户终端2发送的用户标识符和密码以及用户控制文件202来执行登录处理。接下来，服务器2通过使用从服务器2发送的服务提供请求来执行服务控制客户终端1和提供有服务器的服务控制文件42。当服务器确定需要其他用户的批准来提供服务时，服务器向相关用户使用的客户终端1执行批准请求。当对批准请求的答复是肯定的时，服务器根据上述服务提供请求执行处理。当答复为否定的时候，服务器向用户通知上述服务提供请求是否拒绝批准。

摘要： This invention provides a method for identifying a purchaser who purchased content from which an illegal copy was produced. A provider system encrypts a content purchased by the purchaser using a public key of a purchaser system and sends the encrypted content to the purchaser system. The purchaser system creates a digital signature of the content with the use of a private key of its own and embeds the created digital signature into the received content. When an illegal copy is found, the provider system verifies the digital signature, embedded in the illegal copy as a digital watermark, to identify the purchaser who purchased the content from which the illegal copy was produced.

摘要： An electronic document authenticity assurance technique and an information disclosure system both of which can compatibly realize the assurance of the authenticity of disclosure documents and the deletion of information inappropriate for disclosure. An electronic document is divided into constituent elements and an electronic signature is affixed to an arbitrary subset of a set including all the constituent elements. Otherwise, an electronic signature is affixed to data obtained by binding each of the constituent elements to information specifying the relationship between a respective one of the constituent elements and the structure of the electronic document. Otherwise, the hash values of the respective constituent elements are calculated and an electronic signature is affixed to data obtained by binding the calculated hash values together. Otherwise, random numbers generated for the respective constituent elements are bound together, then the hash values of the respective random-numbered constituent elements are calculated, and then an electronic signature is affixed to data obtained by binding the calculated hash values together.
