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

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• receive, at a privacy transaction platform server, via a communication network, from a transaction network server, a transaction approval request for a transaction associated with a user device and a requesting server, the transaction approval request comprising a plurality of proffered transaction strings and one or more proffered server properties associated with the requesting server;
• retrieve, from a database associated with the privacy transaction platform server, a privacy transaction record associated with the user device comprising a plurality of tagged transaction strings associated with a provider server and one or more provider server properties associated with the provider server;
• determine whether there is a transaction string match between the plurality of proffered transaction strings and the corresponding plurality of tagged transaction strings;
• determine whether there is a server match between the requesting server and the provider server based on a validity metric for the transaction approval request, wherein the validity metric is determined based on an analysis of the one or more proffered server properties and the one or more provider server properties, and wherein a server match exists based on the validity metric exceeding a specified confidence threshold;
• and
• transmit, responsive to determining that there is a transaction string match and a server match, via the communication network, to the transaction network server, a validation response to the approval request configured to complete the transaction between the user device and the requesting server.

A system comprising:

• one or more processors;
• and a non-transitory memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:
• receive, at a privacy transaction platform server, via a communication network, from a transaction network server, a transaction approval request for a transaction associated with a user device and a requesting server, the transaction approval request comprising a plurality of proffered transaction strings and one or more proffered server properties associated with the requesting server;
• retrieve, from a database associated with the privacy transaction platform server, a privacy transaction record associated with the user device comprising a plurality of tagged transaction strings associated with a provider server and one or more provider server properties associated with the provider server;
• determine whether there is a transaction string match between the plurality of proffered transaction strings and the corresponding plurality of tagged transaction strings;
• determine whether there is a server match between the requesting server and the provider server based on a validity metric for the transaction approval request, wherein the validity metric is determined based on an analysis of the one or more proffered server properties and the one or more provider server properties, and wherein a server match exists based on the validity metric exceeding a specified confidence threshold;
• and
• transmit, responsive to determining that there is a transaction string match and a server match, via the communication network, to the transaction network server, a validation response to the approval request configured to complete the transaction between the user device and the requesting server.
