Patent number: 10834536Abstract: Estimating a location of a device at a particular point of time may incorporate one, two, or more different location data points. The location data points may be derived from communications networks, where there may be different mechanisms for determining location. As part of the location estimation, each cellular location in a cellular network may have a different error range associated with each cell, for example. The error range for each cell may be generated by collecting precise location data from Global Positioning System or other mechanism with high accuracy, and comparing that data to location data gathered from other sources. A database of error ranges for each cell and each location mechanism may be gathered and used to estimate the actual location of a device for a given time period.Type: GrantFiled: January 5, 2018Date of Patent: November 10, 2020Assignee: DataSpark, Pte. Ltd.Inventors: Ying Li, The Anh Dang

Patent number: 10827308Abstract: Real time status of a device's movements may be determined from a sequence of location observations. The status may be in the form of a state, which may be “stay”, “transit”, “pause”, and “unknown”. A state transition may occur from transit to stay when the device has remained within a predefined radius for a predefined time period. Prior to being labeled a “stay”, a device that may have ceased moving but has not stayed at that location for enough time may be labeled “pause”. For those devices in a “transit” state, a mode of transport may be determined. The real time analysis system may be a low-overhead mechanism by which new location observations may be received and processed. The resulting data may be used by traffic analysts to monitor congestion, for real time traffic data for commuters, and other uses.Type: GrantFiled: February 14, 2018Date of Patent: November 3, 2020Assignee: Data Spark, Pte LtdInventors: Ying Li, The Anh Dang

Publication number: 20200210458Abstract: A dataset's uniqueness level may be calculated by analyzing a dataset to determine a uniqueness level. In cases where the uniqueness level may be too low for a particular purpose, meaning when the dataset may not provide enough anonymity, the dataset may be adjusted by recomputing the dataset with different resolutions of spatial data, temporal data, content data, and relationship data. By adjusting the resolution or accuracy of the data elements, the uniqueness level may thereby be adjusted. An error calculation may be determined by comparing the adjusted dataset to the original data, and the error value may represent the consistency of the data to the original data. The uniqueness level may be used as an assurance level of anonymity, which may be advertised when a dataset is sold or transferred to a third party for analysis.Type: ApplicationFiled: March 5, 2020Publication date: July 2, 2020Inventors: The Anh DANG, Amy Xuemei SHI-NASH

Publication number: 20200120448Abstract: A visit mobility gene may be generated from analyzing raw location observations and may be made available for further analysis. The visit mobility gene may include summarized statistics about a certain location or location type, and in some cases may include ingress and egress travel information for visitors. The visit mobility gene may be made available to third parties for further analysis, and may represent a concise, rich, and standardized dataset that may be generated from several sources of mobility data.Type: ApplicationFiled: February 17, 2017Publication date: April 16, 2020Applicant: Dataspark Pte, LtdInventors: Ying LI, The Anh DANG

Publication number: 20200112835Abstract: Mobility observations may be analyzed to create so-called mobility genes, which may be intermediate data forms from which various analyses may be performed. The mobility genes may include a trajectory gene, which may describe a trajectory through which a user may have travelled. The trajectory gene may be analyzed from raw location observations and processed into a form that may be more easily managed. The trajectory genes may be made available to third parties for analysis, and may represent a large number of location observations that may have been condensed, smoothed, and anonymized. By analyzing only trajectories, a third party may forego having to analyze huge numbers of individual observations, and may have valuable data from which to make decisions.Type: ApplicationFiled: February 17, 2017Publication date: April 9, 2020Inventors: Ying LI, The Anh DANG

Publication number: 20200107163Abstract: Sequences of location data points can be broken down into travel periods and stay periods through historical analysis of location data points. The noise and inaccuracies of location data points gathered from communications networks, such as mobile telephony networks, makes it difficult to accurately estimate when a user has stayed or dwelled at a particular location. The stay analysis may generate clusters of sequential location coordinates and may identify data points that appear to show movement but are likely to be noise, which can be artifacts of the communications network. Further, stay or travel sequences may initially be defined using thresholds of time and distance. Such thresholds may vary from one location to another and may be gathered and optimized over time.Type: ApplicationFiled: February 14, 2018Publication date: April 2, 2020Inventors: Ying LI, The Anh DANG

Patent number: 10453335Abstract: A traffic routing and analysis system uses data from individual cellular or mobile devices to determine traffic density within a transportation network, such as subways, busses, roads, pedestrian walkways, or other networks. The system may use historical data derived from monitoring people's travel patterns, and may compare historical data to real time or near real time data to detect abnormalities. The system may be used for policy analysis, predicted commute times and route selection based on traffic patterns, as well as broadcast statistics that may be displayed to commuters. The system may be accessed through an application programming interface (API) for various applications, which may include applications that run on mobile devices, desktop or cloud based computers, or other devices.Type: GrantFiled: July 14, 2015Date of Patent: October 22, 2019Assignee: DataSpark, Pte.

Publication number: 20190310342Abstract: A user's location may be estimated by applying a probability function to raw user location data taken from various telephony or wireless systems. The probability function may estimate a user's location based on a training dataset that may be generated a priori to the analysis. A training dataset may be generated or updated by analyzing queries made with global positioning system (GPS) data to extract a device's GPS location. The probability function may be generated in part from physical maps. The estimated location may improve location accuracy, especially when attempting to map a user's location with accuracies that may be much smaller than a cell of a cellular telephony system.Type: ApplicationFiled: December 23, 2016Publication date: October 10, 2019Inventors: Yibin NG, Yunye JIN, Jingxuan WANG, The Anh DANG, Ying LI

Patent number: 10176340Abstract: A system may generate abstracted graphs from a social relationship graph in response to a query. A query may identify a person for which permission has been obtains to collect their data. The abstracted graphs may include summary statistics for various relationships of the person. The relationships may include other persons, places, things, concepts, brands, or other object that may be present in a social relationship graph, and the relationships may be presented in an abstracted or summarized form. The abstracted form may preserve data that may be useful for the requestor, yet may prevent the requestor from receiving some raw data. When two or more people have given consent, the data relating to the consenting persons may be presented in a non-abstracted manner, while other data may be presented in an abstracted manner.Type: GrantFiled: March 13, 2016Date of Patent: January 8, 2019Assignee: DataSpark, Pte.
