Devices, systems, and methods for performing particularized encryption of confidential information within real-world data files that are subsequently stored within a cloud environment are described. Specific rules/logic are executed in a local computing environment to identify the type(s) and/or magnitude(s) of confidential information contained within each real-world data file. The identified type(s) and/or magnitude(s) of confidential information is thereafter specifically encrypted using various encryption processes. Once encrypted, the data is packaged and stored within a cloud environment without the need for further encryption at either the local computing or cloud environments.

Systems, methods, and devices for securing data stored in a cloud environment

A solution to resolve ambiguous merchant data in connection with processing a cashless transaction request in a real-time manner. Provided according to the present disclosure are a system and method including a binary-searchable non-transitory computer-readable medium is configure to store a first set of unambiguous merchant identification data having plural data entries therein, each entry corresponding to a merchant. A binary search of the first set of unambiguous merchant identification data is carried out using search keys based upon the ambiguous merchant identification data to determine whether one or more entries of the first set satisfies at least one of a second set of partial match criteria for comparing the ambiguous merchant identification data with the first set of unambiguous merchant identification data. An entry of the first set of unambiguous merchant identification data is assigned to correspond with the ambiguous merchant identification data where at least a predetermined number of the second set of partial match criteria are met.

Instantaneous merchant information retrieval for financial transactions

A solution to disambiguate ambiguous merchant data in connection with processing a cashless transaction request in a real-time manner. Provided according to the present disclosure are a system and method including a binary-searchable non-transitory computer-readable medium is configure to store a first set of unambiguous merchant identification data having plural data entries therein, each entry corresponding to a merchant. A binary search of the first set of unambiguous merchant identification data is carried out using search keys based upon the ambiguous merchant identification data to determine whether one or more entries of the first set satisfies at least one of a hierarchical second set of partial match criteria for comparing the ambiguous merchant identification data with the first set of unambiguous merchant identification data. An entry of the first set of unambiguous merchant identification data is assigned to correspond with the ambiguous merchant identification data where at least a predetermined number of the second set of partial match criteria are met.
