System and computer-implemented method of permitting or arbitrating encrypted electronic transactions to occur among an intermediary and an author in an electronic data system only when an interaction occurs between the author and a candidate who was exposed by the intermediary to data published by the author. The author publishes criteria about a candidate, and the candidate posts information about the candidate, which is ingested and married to personally identifiable information about the candidate. A score is calculated indicating a correlation between the candidate and the published criteria, and an intermediary exposes the candidate to the criteria, which is tracked. When the candidate completes an interaction with the author, an encrypted transaction is permitted to occur between the author and the candidate through a proxy, without the author knowing the identity of the intermediary who facilitated the introduction.

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing blockchain-based trustable transaction services. One of the methods includes: storing order data of an order between a buyer and a seller on a blockchain of a blockchain network, the order data including one or more payment conditions, verifying that the buyer has a trustable automatic payment service guaranteed by a buyer financial institution, generating a smart contract for the order based on the order data on the blockchain, and executing the smart contract to automatically instruct the buyer financial institution to make a payment of the order for the buyer to the seller according to the trustable automatic payment service in response to determining that a payment condition for the payment specified in the smart contract is met based on order status data uploaded to the blockchain.

An online concierge system allows users to order items from a warehouse having multiple physical locations, allowing a user to order items at any given warehouse location. To select a warehouse location for a warehouse selected by a user, the online concierge system identifies a set of items that the user has a threshold likelihood of purchasing from prior orders by the user. For each of a set of warehouse locations, the online concierge system applies a machine-learned item availability model to each item of the identified set. From the availabilities of items of the set at each warehouse location of the set, the online concierge system selects a warehouse location. The online concierge system identifies an inventory of items from the selected warehouse location to the user for inclusion in an order.

An online concierge system maintains historical orders received from a user that include one or more items. For items included in one more historical orders, the online concierge system determines an interval between orders including an item, providing an indication of a frequency with which the user orders the item. When the online concierge system receives a request to create an order from the user, in response to an amount of time between a most recently received order including the item and a time when the request was received is within a threshold duration of the interval between orders including the item, the online concierge system selects an item from a category including the item. The selected item may be the item or an alternative item in the category. Subsequently, the online concierge system displays an interface for the user that is prepopulated with information identifying the selected item.

Systems and methods for facilitating proposals and donations of objects is provided. The method includes transmitting object information from a donor device to be presented in a catalogue of a objects offered for donation and shared with a plurality of prospective donees. Thereafter, receiving a plurality of proposals for acquisition of the object from the plurality of prospective donees, wherein the system is configured to concurrently transmit all of the plurality of proposals to the donor device. The donor using the donor device selects a proposal from the plurality of proposals based on the preference of the donor. The object information may include a plurality of terms and conditions, wherein the terms and conditions are stipulations for a prospective donee in order to acquire the donated object. Advantageously, donations services including loan agreement, shipping arrangements, appraisal may be efficiently formalized using the systems and methods.

In an approach to provide contact-less shopping assistance to a user, a computer implements a method for receiving customer authentication data from a user and associating the customer authentication data with a tagged wearable device and a tagged mobility device with the user. The method further includes receiving an indication the user is wearing the tagged mobility device, and that the user is entering a shopping facility using the tagged mobility device. The method further includes receiving a user instruction to capture an image causing the tagged wearable device to capture the image, identifying a bar code in the image, determining an item based on the bar code and transmitting an action instruction to the tagged mobility device to retrieve the item and secure the item. The method further includes receiving an indication that the user has completed the task and delivering the item to the user.

Provided is a system for providing removals simulation using VR and AR and brokering real estate therethrough, and the system includes: a background providing unit which extracts background information inside a real estate object provided by a real estate provider and presents the background information to the real estate customer; and an AR providing unit which overlaps props information of a real estate customer on the background information of the real estate object so as to be arbitrarily arranged by the real estate customer, wherein the real estate customer can simulate by overlapping props information on the background information, when the simulation is determined, the determined information is transmitted to a number of moving service servers, and thus provides an advantage in that a number of moving centers can propose moving costs to the real estate customer in a reverse auction manner based on the props information.

A population activity mapping method may include detecting a plurality of wireless mobile devices within a geographic region. Individual wireless mobile devices may include a processor, a user interface, a transmitter and a receiver. The detecting operation may be performed by use of a wireless access point, a GPS satellite, and/or a base station, and may be performed at least two different points in time. Input data may be provided based upon the detecting operation. A distance and speed at which the mobile devices travel within the geographic region may be discerned dependent upon the input data. The discerning operation is performed by at least one processor of a computer network. A time and/or location at which salable output is to be made available and/or an amount of salable output to be made available may be determined dependent upon the discerning operation.

Example embodiments provide a system that uses a conversational agent to collect information and publish the information on a network. A computer-implemented conversational agent establishes a communication session with a user and receives conversational information via a simulated conversation between the user and the computer-implemented conversational agent via the communication session, whereby the conversational information comprises information to be published. The computer-implemented conversational agent also receives, via a graphical user interface, an upload of an image that is associated with the information to be published. The computer-implemented conversational agent then causes publication of the information to be published and the uploaded image.
