    摘要: A purchaser apparatus stores “anonymous order information including an order ID and purchaser identity verifying information” and “purchaser identity proving secret information”. A shop apparatus stores “anonymous order information including an order ID and purchaser identity verifying information”. If necessary, a purchaser sends a request including an order ID and zero knowledge proving information that a purchaser knows the purchaser identity proving secret information, from a purchaser apparatus to a shop apparatus. A shop apparatus verifies the zero knowledge proving information, based on purchaser identity verifying information retrieved from an order ID included in the request. Therefore, the unlinkability for past use is eliminated if necessary, and inconvenience caused by the unlinkability is eliminated.

    摘要: Disclosed are an etching solution for a substrate and a substrate-etching method, which can prevent the contamination of a substrate, particularly a semiconductor substrate, with metal impurities. The etching solution comprises a dicarboxylic acid represented by the general formula (1) or a salt thereof and 20% (W/W) or more of an alkali metal hydroxide. The substrate-etching method comprises the step of etching a substrate with said etching solution. (wherein T1 and T2 independently represent a hydrogen atom, a hydroxyl group, a carboxyl group or an alkyl group having 1 to 3 carbon atoms, or T1 and T1 together form a bond; and R1 to R4 independently represent a hydrogen atom, a hydroxyl group, a carboxyl group or an alkyl group having 1 to 3 carbon atoms, provided that, when T1 and T2 do not together form a bond, any two of T1, T2 and R1 to R4 represent a carboxyl group, and any one of the remainder represents a hydroxyl group, and the others independently represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and when T1 and T2 together form a bond, any two of R1 to R4 represent a carboxyl group, and the others independently represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms.)

    摘要: A source of MPEG2 video data is connected with a dedicated AV device or personal computer by means of an IEEE 1394 interface. A transmission unit in the source has an IEEE 1394 encryption unit and a sending I/F unit. A reception unit varies between the dedicated AV unit and the personal computer. In the reception unit of the dedicated AV device, a receiving I/F unit and a decryptor are integrally incorporated into one semiconductor chip and an MPEG2 decoder is incorporated into one semiconductor chip. In the reception unit of the personal computer, the receiving I/F unit is formed of one semiconductor chip, and the decryptor connected to the I/F unit through a bus, and the MPEG2 decoder are formed of one semiconductor chip. Thus, data before decryption will not appear on the bus, which prevents MPEG2 video data from being taken out of the computer for illegal copying purposes. In addition, the reception unit is made to have a different physical configuration depending on whether it is to be mounted in the dedicated AV device or the personal computer. This will prevent the reception unit (including the decryptor) of the dedicated AV device from being connected in the personal computer in place of its associated reception unit (excluding the decryptor).

    摘要翻译: MPEG2视频数据源通过IEEE 1394接口与专用AV设备或个人计算机连接。 源中的传输单元具有IEEE 1394加密单元和发送I / F单元。 接收单元在专用AV单元和个人计算机之间变化。 在专用AV设备的接收单元中,一个接收I / F单元和解密器被整合在一个半导体芯片中,并且MPEG2解码器被并入到一个半导体芯片中。 在个人计算机的接收单元中,接收I / F单元由一个半导体芯片形成,并且解码器通过总线连接到I / F单元,并且MPEG2解码器由一个半导体芯片形成。 因此,解密之后的数据不会出现在总线上,这样就不会将MPEG2视频数据从计算机中取出来进行非法复制。 此外,接收单元根据是否要安装在专用AV设备或个人计算机中而具有不同的物理配置。 这将防止专用AV设备的接收单元(包括解密器)代替其关联的接收单元(不包括解密器)连接在个人计算机中。
