Abstract: The disclosure describes an apparatus having programmed instructions that when executed cause the apparatus to receive, via a communication network, information regarding suspicious fraud activity at a first location involving a plurality of transaction cards; monitor changes over a first time interval to received information regarding suspicious fraud activity at the first location; and identify a point-of-compromise (POC) location based on monitored changes surpassing a threshold indicating suspicious fraud activity at the first location over the first time interval.

Abstract: A method comprises storing a plurality of entity profiles; applying a predetermined first set of rules to a plurality of attribute-value pairs of the plurality of entity profiles; identifying a first set of entity profiles that satisfy the predetermined first set of rules; identifying a second set of entity profiles that satisfy the predetermined second set of rules; and updating a first attribute-value pair of the first and second sets of entity profiles by adding a first label to the first attribute-value pair responsive to determining the first set of entity profiles and the second set of entity profiles share a common entity profile.

Abstract: A method comprises storing a plurality of accounts; and generating a hierarchical data structure from the plurality of accounts by: identifying a first set of accounts and a second set of accounts responsive to the first set of accounts and the second set of accounts satisfying a first set of rules; linking the first set of accounts to a first entity profile and the second set of accounts to a second entity profile; and responsive to the first plurality of profile attribute-value pairs and the second plurality of profile attribute-value pairs of the second entity profile satisfying a second set of rules, linking the first entity profile and the second entity profile to a household entity profile by inserting a household identifier into a household attribute-value pair of each account of the first set of accounts and the second set of accounts.

Abstract: A method for synthesizing sucrose-6-ester includes: (a) in the presence of a polar aprotic solvent, contacting an organic phosphine compound represented by formula I with sucrose and an organic tin compound; (b) removing water to obtain a reaction liquid containing a tin-sucrose adduct; and (c) contacting the reaction liquid containing the tin-sucrose adduct with an acid anhydride compound to prepare a sucrose-6-ester. In formula I, R1, R2, and R3 each are a linear or branched alkyl having 1 to 20 carbon atoms, a cycloalkyl having 3 to 10 carbon atoms, or an aryl having 6 to 10 carbon atoms; moreover, the R1, R2, and R3 are identical groups, partially identical groups, or different groups from each other. According to the method, the reaction conversion rate and selectivity are greatly improved; moreover, it is easy to realize industrial application.

Abstract: Disclosed are a method, a system, and a non-transitory computer readable medium for identifying data entries associated with an entity. A first rule is applied on a plurality of data entries associated with a plurality of entities to obtain a first set of data entries from the plurality of data entries. Each data entry includes corresponding attributes. The first rule is to search for data entries with a first group of attributes. A second rule is applied on the plurality of data entries associated with a plurality of entities to obtain a second set of data entries from the plurality of data entries. The second rule is to search for data entries with a second group of attributes. A third set of data entries associated with a single entity is obtained based on the first set of data entries and the second set of data entries.
