A method of checking a sheet as to forgery thereof, the sheet being provided with an electronic circuit chip from or in which information can be read out or written and having visible information. The method includes a step of encrypting the visible information of the sheet and storing the encrypted visible information in the electronic circuit chip, and a step of determining discriminatively the authenticity of the sheet by comparing the visible information of the sheet with the information stored in the electronic circuit chip.

Method of checking authenticity of sheet with built-in electronic circuit chip

A non-contact identification semiconductor device is provided with a semiconductor chip including a receiving circuit that receives an inquiry to the non-contact identification semiconductor device, a memory that stores identification information of multiple bits and a sending circuit that sends the identification information. An antenna coupled to said semiconductor chip receives the identification information from said semiconductor chip and transmits the identification information outside of said non-contact semiconductor. The long side length of the semiconductor chip is not greater than 0.5 mm in plane dimension, and the identification information is stored by a pattern printed by an electron beam.

Semiconductor devices and manufacturing method therefor

This Application is intended to provide a method for effectively protecting paper or film-form media against forgery. This can be achieved by, for example, embedding in a paper or film-form medium a thin semiconductor chip up to 0.5 mm square, equipped with an antenna, and characterized in that the side walls of the semiconductor chip are formed using oxide films, and in that multiple such semiconductor chips are separated by etching. Limiting the size of these semiconductor chips to 0.5 mm or less enables improvement against bending and concentrated loads, and separating the semiconductor chips by etching results in semiconductor chips free from cracking and breakage. Also, the oxide films constituting the side walls of the semiconductor chips prevents short-circuiting at edges during connection to the respective antennas. Thus, simplified processes can be adopted.

A method of checking sheets as to forgery thereof, the sheet being provided with an electronic circuit chip from which information can be read cut or written and having visible information. The method includes a step of encrypting the visible information of the sheet and storing the encrypted visible information in the electronic circuit chip, and a step of determining discriminatively the authenticity of the sheet by comparing the visible information of the sheet with the information stored in the electronic circuit chip.

A client is connected to a server for providing electronic commerce services in electronic commerce. An order is transmitted for a product in response to an input by a user to the server through a communications network. A trading identifier associated with the order and data on the contents of the order is received from the server, which is stored in a storage device. Associated trading processing information includes a present status of processing for processing initiated for the order, a present status of processing for delivery of the product corresponding to the order, a present status of processing for payment processing for the trading, and the trading identifier. During updating, a trading identifier is compared with trading identifiers included in the stored trading processing information, and a warning is output if they are not coincident. Updated trading processing information is added to the trading information stored in the storage device if they are coincident. The present status of processing for the processing initiated for the order, processing for delivery of the product corresponding to the order, and processing for the payment processing for the trading are managed until the order processing, delivery, and payment processing are completed.

In a judgement support system and method, essential items to be necessarily judged and optional items to be optionally judged by a user are displayed on a menu screen, thereby allowing a judgement through intuitive knowledge of the user. After judgement results of all essential items have been inputted, the system is allowed to stop its operation. When a judgement result is inputted, an evaluation of the judgement is outputted in accordance with a predetermined rule. The evaluation includes updating a judgement item. For example, an essential judgement item is added. The menu screen is dynamically changed during judgement.

Judgement support system and method

A method of supporting decision-making for predicting future time-series data by using measured values of time-series data stored in a storage and knowledge stored in a knowledge base. The knowledge is related to interpretation and prediction of the time-series data. A plurality of time-series data stored in the storage device is prepared in an order of time-serial points corresponding to the time-series data. Knowledge which includes reference to the time-series data using a relative time interval from the time-series data is stored to the knowledge base. One the time-serial points of the time-series data is designated. Thereafter, the relative time interval in the knowledge is subtracting from the designated time-serial point to determine the time-serial point corresponding to the time-series data, and the future time-series data is inferred by using the knowledge and the time-series data.

Method of supporting decision-making for predicting future time-series

Fuzzy knowledge stored in a knowledge base is written into a memory. When fuzzy reasoning is executed by a fuzzy reasoning unit based on the content of the memory, a control unit in a central processing unit may modify the knowledge base in the memory. The control unit is programmed such that after it has modified the knowledge base in the memory, it causes a reasoning execution unit to repeatedly and automatically execute predetermined fuzzy reasoning by the number of times corresponding to the number of input data. The control unit also modifies the knowledge base and causes the reasoning execution unit to execute the fuzzy reasoning. By reading out the knowledge base in the memory, it is possible to verify the validity of the fuzzy knowledge without executing the simulation of the fuzzy reasoning. The fuzzy reasoning course of the reasoning execution unit may be stored in another memory. In this case, the control unit may display the fuzzy reasoning result on a display device in an expression easily understandable by a user, based on the content of the other memory.

Method and apparatus for fuzzy knowledge reasoning

A method of supporting the decision-making on the basis of a table type data is disclosed, which comprises the processes of defining a knowhow relating to the interpretation of the table type data, storing the knowhow in a storage unit, effecting the reasoning by application of the knowhow thus defined, and evaluating the knowhow thus defined. (a) Information is applied by way of an input unit for starting any of the process of defining a knowhow, effecting the reasoning by application of the knowhow and ending the system process, (b) the information thus inputted is discriminated to execute a corresponding process of operation, and (c) if the corresponding process of operation is other than ending, the process is returned to step (a).

In a production system having a memory for storing a group of rules each comprising a condition part and a conclusion part, inference means for inferring by using the group of rules and a working memory, whether a condition part is true or false in the working memory is determined, and if it cannot be determined, a rule having a conclusion part as to whether the fact is true or false is searched, and the conclusion part of the searched rule is used for backward reasoning. If the rule is not found by the search, an inquiry is made to a user.

Inference method

An information processing system which has a portion for storing metaknowledge and a portion for utilizing the metaknowledge stored in said storage portion. In newly acquiring knowledge, the utilizing portion utilizes the metaknowledge stored in said storage portion. A knowledge input prompting function that works to utilize the metaknowledge makes reference to metaknowledge in the metaknowledge memory function, looks for knowledge that is lacking, and prompts the input thereof. An input knowledge checking function which also utilizes the metaknowledge makes reference to metaknowledge to look for constraint related to the input knowledge, and evaluates whether it is satisfied or not. These utilization functions make it possible to keep the justification and consistency of knowledge acquired.
