Systems and methods for automatically securing and validating multi-server electronic communications over a plurality of networks

Abstract

In one embodiment, a method includes receiving, from a user device, a first request for a privacy transaction card comprising a plurality of transaction metadata strings associated with a pending transaction between the user device and a first merchant server, analyzing, using a machine learning model, the transaction metadata strings in the first request to determine a risk assessment score for the first request, the machine learning model being trained to determine risk assessment scores based on multiple second requests stored in a privacy transaction database, determining whether the risk assessment score for the first request exceeds a specified risk threshold associated with the pending transaction, generating, upon determining the risk assessment score is below the specified risk threshold, a privacy transaction card comprising a unique privacy payment card number associated with the user device and the first merchant server, and transmitting, to the user device, the privacy transaction card.
