Abstract: A secure electronic messaging system includes processors coupled to a network, and constituent applications, services, and processes configured to securely exchange messages between participants such as hosts and recipients, and to protect personally identifying information (PII). The system and processor(s) are configured to generate a deanonymization probability (DP) for an anonymized dataset (ADS) responsive to a query received from the network, and to generate the ADS with pseudoidentities of recipients, when the DP does not exceed a predetermined DP threshold (DPT). The system thereby reduces the probability that the ADS and or pseudoidentities can be deanonymized, and thereby enables secure message exchanges between the participants, while protecting and without sharing the PII of participant identities. When DPs exceed the DPT, the system generates error messages, and or alternative queries that generate ADS s with DPs that do not exceed the DPT.
