摘要： A time stamp generating system has a time distribution server for generating time data depending on time and a user PC for holding time certification objective digital data. The time distribution server generates time data corresponding to a time point and distributes the time data. The user PC calculates time stamp generating data by using the time certification objective data as an input, acquires the time data generated by the time distribution server, and processes the time data on the basis of the time stamp generating data to obtain a time stamp.

摘要： According to the present invention, techniques, including a method and system, for restoring and/or validating data and/or associated signature log entries are provided. One embodiment of the present invention provides a method for validating a restored message, having an entry generated in a signature log for a message, where the entry includes cryptographic information associated with the message; Next, when said message is lost, the restored message is generated responsive to a request; and the restored message is validated using the signature log. In another embodiment a method for validating a selected log entry by using a signature log having a plurality of recorded log entries is provided. The method includes: computing a cryptographic value for the selected log entry; and determining if the cryptographic value is part of another recorded log entry.

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.
摘要翻译：本发明提供一种用于识别购买从其产生非法拷贝的内容的购买者的方法。提供者系统使用购买者系统的公钥加密由购买者购买的内容，并将加密的内容发送给购买者系统。购买者系统通过使用其自身的私钥来创建内容的数字签名，并将创建的数字签名嵌入到接收的内容中。当发现非法副本时，提供者系统将嵌入在非法拷贝中的数字签名作为数字水印进行验证，以识别购买从其中产生非法拷贝的内容的购买者。

摘要： An original signature can be verified even if a signed image data is properly altered in its portion. The digital image data is divided into a plurality of configurational elements, and each of the feature values of the elements are calculated, so that the signature is created by combining the feature values. In case the configurational elements are to be deleted, they are substituted by substitutive data, and only the feature values are stored. The verification is created by using the stored feature values as the substituted elements and by using the calculated feature values as the remaining elements, so that the signature is verified with the signature attached to the digital image data.
摘要翻译：即使签名的图像数据在其部分中被适当地改变，也可以验证原始签名。数字图像数据被分成多个配置元素，并且计算元素的每个特征值，从而通过组合特征值来创建签名。在配置要素被删除的情况下，它们被代用数据代替，只存储特征值。通过使用存储的特征值作为替代元素并通过使用计算的特征值作为剩余元素来创建验证，使得签名被附加到数字图像数据的签名来验证。

摘要： A method of communication involving processing by instruction using one or a combination of information units, when a user instructs a terminal to display contents and procedure of a communication, or to totalize the contents of the communication, or when a manager terminal instructs a field of the communication to provide a function of the communication corresponding to an object or stage of the communication. Information units forming the contents of the communication include cards, and information units forming premising information of a communication and a basis of the communication include boards. An information unit comprises a board identifier and attribute information for specifying a function of a board, such as a relationship between the board and cards. To provide a communication function corresponding to an object and stage of the communication, a template conforms to the object and stage so a manager can select and utilize the template.
