Abstract: The present invention relates to a method for providing a mixed reality service by a server and a system for performing the same, the method comprising the steps of: generating a mixed reality conference room for arbitrary three-dimensional modeling data; receiving tracking information collected by at least one terminal participating in the mixed reality conference room; generating a virtual image for the three-dimensional modeling data and at least one object, on the basis of the tracking information; and transmitting the virtual image to the at least one terminal, wherein the tracking information includes space identification information of a reality space of each terminal and motion information of each terminal, and the virtual image is synthesized with a reality image in the at least one terminal so as to be displayed as a mixed reality image.

Abstract: A dust collector separates dust from the gas including the dust such as smoke discharged from a coffee roasting machine. The dust collector uses a water spray. The dust collector can prevent blockage of nozzles of a upper water supply line and a side water supply line by arranging the upper nozzle and the side nozzle, which spray water, to be faced to each other within the body of the dust collector. Water flows along the side within the inlet which is slant downward, which allows the gas to flow into the body of the dust collector, and a separate assistant water supply line is connected to the inlet.

Abstract: A system and method is provided for performing callbacks in a commercial transaction processing system. The system includes a transaction processor to receive a transaction request from a user. The transaction request includes an amount to be transferred between a user account and a first bank account associated with a first bank. A second bank is coupled to the transaction processor to transmit an instruction to the first bank to transfer the amount between the first bank account and the user account. The second bank receives a response from the first bank indicating whether the amount can be transferred, and selectively generates a callback message based on the response from the first bank. The transaction processor further determines whether to update the user account to reflect the amount to be transferred based, at least in part, on the callback message.

Abstract: A system and method is provided for managing roles-based access to resources arranged in a hierarchy. A hierarchical roles-based access control system receives a request from a user to access a particular resource. The system identifies a set of permissions for the user based on user identification information provided with the request. Specifically, each permission in the set is associated with a respective resource and one or more actions that the user is authorized to perform on that resource. The system then determines a hierarchical lineage for the particular resource in relation to each resource associated with the set of permissions, and determines whether the user is authorized to access the particular resource based, at least in part, on the hierarchical lineage.

Abstract: A system and method is provided for detecting fraud during merchant on-boarding. A transaction processing system receives a payment request from a merchant and retrieves merchant metadata associated with a merchant profile based on the payment request. The system determines an initial risk score for the transaction based, at least in part, on the merchant metadata. The risk score may then be dynamically adjusted based on the received payment request and the merchant metadata. The system may further determine, based on the risk score, whether to notify a system administrator of a high risk transaction, request a review of the transaction by the system administrator, and/or decline the transaction.

Abstract: A system and method is provided for detecting fraud during merchant on-boarding. A transaction processing system receives signup information from a merchant requesting to create a new merchant profile. The signup information may include input data specifying a bank account of the merchant and metadata associated with a device used to submit the input data. The system then compares the signup information with merchant information stored in a merchant database and selectively identifies the new merchant profile as fraudulent based, at least in part, on the comparison. For some embodiments, the system may identify the new merchant profile as fraudulent if the bank account specified by the input data matches bank account information associated with an existing merchant profile or a known fraudulent profile.

Abstract: A linguistic phrase including a plurality of adjacently positioned characters arranged in a first sequence may be displayed. A first command may be received to obscure the linguistic phrase by separating the plurality of adjacently positioned characters into constituent characters In response to receiving the first command, the constituent characters may be displayed separate from each other to obscure the linguistic phrase. A second command may be received to combine at least two of the constituent characters to form a particular linguistic phrase including a number of adjacently positioned characters arranged in a particular sequence. Validity of the particular linguistic phrase may be evaluated. Upon determining that the particular linguistic phrase is valid, the particular linguistic phrase may be displayed including the number of adjacently positioned characters arranged in the particular sequence.

Abstract: A delivery box system for delivering an article is providing, including a navigation device for sending and receiving reservation reguests and information, payment information, navigation execution ID information and position information of a particular related delivery box from a central computer of a central management center. The navigation device automatically calculates navigation information based on the navigation execution ID information, as well as guides the deliveryman from the present position thereof to the particular related delivery box based on the position information of the related delivery box received from the central computer.
