Patent number: 11528202Abstract: A packet flow monitoring device, a packet data extraction device, an extraction data aggregation device, and a program for efficiently and highly accurately monitoring a packet flow in a video or audio communication system constructed by an Ethernet (registered trademark) frame or IP packet network. This packet flow monitoring device includes: a packet data extraction device that replicates all passing packets that pass through one or a plurality of specific network switches on the network and extracts and aggregates some predetermined pieces of information in the replicated passing packets to form and output an extraction data report packet; and an extraction data aggregation device that receives the extraction data report packet, analyzes the extraction data report packet so as to aggregate the predetermined pieces of information in the replicated passing packets included in the extraction data report packet for each packet flow, and records the aggregated information as aggregation data.Type: GrantFiled: October 24, 2019Date of Patent: December 13, 2022Assignee: INTELLIGENT WAVE INCInventors: Tomofumi Koyama, Masahiro Kawaragi, Takuya Kurakake, Masaki Tsuji, Ryo Hasegawa, Keiichiro Katsuta, Naoya Suzuki

Patent number: 8104678Abstract: A payment approval system and a method for approving a payment for credit cards are provided for providing efficient processing while maintaining accuracy in detection of fraud usage of credit cards with an IC chip. Fraud parameters obtained by modeling a pattern of fraud usage is stored in the IC chip equipped in the IC credit card to use for payment approval to achieve improved reliability of offline approval. When offline approval process finds a possibility of fraud usage, online approval for more detailed statistical analysis processing is requested to a host computer. When update information of the fraud parameter used for the judgment is transmitted together with the request for approval and the newest fraud parameter created by analyzing the newest transaction trend etc.Type: GrantFiled: November 28, 2007Date of Patent: January 31, 2012Assignee: Intelligent Wave, Inc.Inventors: Susumu Yoshikawa, Masayuki Ise, Daisuke Sato

Patent number: 7386506Abstract: A fraud score calculating program primarily for use in determining the possibility of credit card fraud can calculate a score reflecting the reliability of a model created based on Bayesian theory. Various factors are extracted from authorization data, and cases are selected for various combinations of the factors. A fraud score is calculated for each case, and a result of score calculation is specified using at least one of the calculated scores. The result of score calculation may be an average of a plurality of the calculated scores. When each score reflects reliability, the result of score calculation may be the largest of the calculated scores.Type: GrantFiled: December 30, 2003Date of Patent: June 10, 2008Assignee: Intelligent Wave Inc.Inventors: Osamu Aoki, Mikinori Seita

Patent number: 7216128Abstract: A data merging program causes a computer to perform a step of selecting a first cell as a starting point of merging; a step of comparing a first numerical value, which is recorded in the first cell, with a preset reference value; a step of, if the first numerical value is smaller than the reference value, calculating a total value of the first numerical value and a second numerical value recorded in a second cell adjacent to the first cell in the same column; a step of comparing the total value with the reference value and, if the total value is smaller than the reference value, setting a third cell into which the first and second cells are merged and recording the total value in the third cell; and a step of selecting the third cell as a new starting point of merging.Type: GrantFiled: December 30, 2003Date of Patent: May 8, 2007Assignee: Intelligent Wave, Inc.Inventors: Osamu Aoki, Mikinori Seita

Publication number: 20040236696Abstract: A fraud determining system adds, to authorization data concerning a present use, history information, such as a difference in time of use or monetary value between the authorization data and authorization data concerning an immediately previous use. When a determination as to whether the present use involves a fraud is made on the basis of the authorization data concerning the present use, it is possible to determine whether or not the present use is irregular from the history information. The result of the determination is reflected in a score, and therefore, the score can be calculated with high reliability.Type: ApplicationFiled: December 30, 2003Publication date: November 25, 2004Applicant: INTELLIGENT WAVE, INC.Inventors: Osamu Aoki, Mikinori Seita

Publication number: 20040225473Abstract: A fraud score calculating program primarily for use in determining the possibility of credit card fraud can calculate a score reflecting the reliability of a model created based on Bayesian theory. A model which is stored in a fraud detection model database 120 obtains new authorization data and continues learning as the number of data samples increases. Calculation of the score is performed by a calculation logic provided in a scoring subsystem 110. The sample number data for a case corresponding to the authorization data are obtained from the model, and the probability of the occurrence of fraudulent use is calculated. The reliability of the model is also calculated on the basis of, for example, the number of the registered samples, and a fraud score is calculated using both the calculated probability of the occurrence of fraud and the calculated reliability of the model.Type: ApplicationFiled: December 30, 2003Publication date: November 11, 2004Applicant: INTELLIGENT WAVE, INC.Inventors: Osamu Aoki, Mikinori Seita
