On-demand secure data entry for representative-assisted transactions

A system for on-demand secure data entry for representative-assisted calls, comprising:

• a computer system comprising a memory, a processor, and a non-volatile data storage device;
• a messaging broker operating on the computer system, the messaging broker comprising a first plurality of programming instructions stored in the memory which, when operating on the processor, causes the computer system to coordinate the operation of a plurality of microservices via messaging, each of the microservices comprising a cloud-based service providing telephony functionality, and wherein the plurality of microservices comprises:
• a session worker microservice providing the following telephony functionality:
• during an unsecured call between a customer and merchant representative via a telephony system of the merchant's telecommunications carrier occurring in non-call center environments controlled by the merchant, receive a request to establish a secured, connected call wherein the customer and the merchant representative remain in voice communication with one another while payment information provided by customer is masked from the merchant representative;
• and
• instruct a dual-tone multi-frequency (DTMF) secure call platform to establish the secured, connected call via a series of API calls to third-party control features of the telephony system of the merchant's telecommunications carrier;
• and
• the dual-tone multi-frequency (DTMF) secure call microservice, the DTMF secure call microservice providing the following telephony functionality:
• receive the instructions to establish the secured, connected call and the phone number allocation from the session worker;
• via a series of API calls to the telephony system of the merchant's telecommunications carrier, instruct the telephony system to:
• park or hold the customer-to-representative call;
• place a representative-to-system call to a dialed number identification service (DNIS) phone number through the softswitch;
• transfer the held customer-to-representative call to the DNIS phone number to connect the customer-to-system;
• and
• connect the representative-to-system call and the customer-to-system call via the phone number;
• secure the representative-to-system call after receipt of validation of the system-to-representative call using a first DTMF secure call space;
• secure the customer-to-system call after receipt of validation of the system-to-customer call using a second DTMF secure call space;
• receive one or more dual-tone multi-frequency (DTMF) tones representing digits from zero to nine from the customer-to-system call;
• and
• using the first DTMF secure call space and second DTMF secure call space, block transmission of the DTMF tones to the representative-to-system call while passing through any other audio from the customer-to-system call to the representative-to-system-call.
