A system for performing task execution in a workflow includes a processor device, at least one modular device having a digital microscope that is interchangeably coupled to the processor device, a memory device coupled to the processor device comprising instructions that when executed by the processor device execute a software service, a network interface, and an electronic workflow system coupled to the processor device via the network interface. The digital microscope corresponds to at least one particular task of a workflow to authenticate a workflow item using discrepancy detection, and the software service controls operation of the at least one modular device and generates forensic metadata from task information received by the digital microscope of the at least one modular device for the electronic workflow system.
