System for transaction authentication

A system comprising:

• a memory for storing computer-executable instructions;
• and
• a processor for executing the instructions stored on the memory, wherein execution of the instructions results in the processor performing operations comprising:
• instantiating an emulator on a host device having a host operating system and processor hardware implementing a first instruction set architecture, wherein the emulator is configured to emulate, in software, different processor hardware implementing one or more second instruction set architectures not including the first instruction set architecture, wherein each instruction set architecture defines addressing modes exception handling and register sets used for operating specific processor hardware;
• configuring a guest operating system, that executes on the emulator using at least one of the second instruction set architectures of the emulated processor hardware, to communicate through an emulated network interface of the emulator, wherein the emulated network interface is configured to facilitate transfer of data to and from the guest operating system via a network stack of the host operating system;
• configuring the emulator to disengage from the host device such that the guest operating system and applications executing on the guest operating system do not have unauthorized access to software and hardware of the host device;
• and
• receiving input data by a guest operating system process that executes, using at least one of the second instruction set architectures of the emulated processor hardware, on the guest operating system.
