Abstract: In one embodiment, a method includes transmitting, by a privacy component, to a first server, a privacy communication request consisting of device data and server data associated with a second server, receiving, by the privacy component, from the first server, a privacy communication string tagged to the second server, wherein the privacy communication string and a privacy communication string record are generated in response to the privacy communication request identifying the second server based on the server data, transmitting, by the privacy component to the second server the privacy communication string, configured to be transmitted to the first server as an approval request, identifying the second server as a requesting server associated with the secure exchange, and receiving, by the privacy component, from the second server, an indication that the approval request was validated based on the requesting server matching the second server identified in the privacy communication string record.

Abstract: In one embodiment, a method includes receiving, at a first server, from a privacy component on a user device, a privacy communication request including device data for the user device and server data for a second server communicating with the user device, generating a privacy communication response to be transmitted by the second server to a third server, the privacy communication response including a privacy communication string tagged to the second server and a privacy communication string record identifying the second server, transmitting, to the privacy component, the privacy communication string, receiving, from the third server, an approval request for a secure exchange associated with the privacy communication string, the approval request identifying a requesting server associated with the secure exchange, analyzing the approval request to determine whether there is a match between the requesting server and the second server, and transmitting, to the third server, a validation response.

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.

Abstract: In one embodiment, a method includes receiving, at a privacy transaction platform server, from a transaction network server, a transaction approval request associated with a user device and a requesting server including proffered transaction strings and proffered server properties associated with the requesting server, retrieving a privacy transaction record associated with the user device including tagged transaction strings and server properties associated with a provider server, determining that there is a transaction string match between the proffered transaction strings and the corresponding tagged transaction strings, determining that there is a server match between the requesting server and the provider server based on a validity metric for the transaction approval request exceeding a specified confidence threshold based on an analysis of the proffered server properties and the provider server properties, and transmitting, to the transaction network server, a validation response approving the requested

Abstract: In one embodiment, a method includes receiving, at a privacy transaction server, from a user device, a privacy transaction card creation request including merchant metadata for a first merchant server, generating a privacy transaction card associated with an issuer server, storing, in a privacy transaction database, a privacy transaction card record for the privacy transaction card, including tagged card data identifying the first merchant server, transmitting, to the privacy component, the privacy transaction card, receiving, from the issuer server, a transaction approval request associated with the privacy payment card, the transaction approval request including transaction metadata identifying a second merchant server, retrieving the privacy transaction card record, analyzing the transaction metadata and the tagged card data to determine whether there is a match between the first merchant server and the second merchant server, and transmitting a transaction approval response indicating whether the transact

Abstract: This disclosure relates to methods and systems for automatically securing and validating multi-server electronic communications over a plurality of networks, without requiring additional physical or programmatic infrastructure on the intermediary servers. A processor-executable component can be transmitted from a first server to a compute device, where it generates a pair of asymmetric cryptographic parameters. The first server uses one of those parameters to verify subsequent communications from the component and respond with tagged privacy communication strings, which the component can provide to a second server as part of a secure communication exchange. The first server can then receive secure communication exchange approval request from a third server and analyze the request to determine a validity metric.

Abstract: Provided are methods for preparing a biological sample for analysis for the presence of a virus, or an exosome or other extra-cellular vesicle, by matrix assisted laser desorption ionisation time of flight mass spectrometry (MALDI-ToF MS). The preparation involves mixing the sample with at least one cationic viral envelope/vesicle disruptor compound, or at least one disulphide reducing agent, or a combination thereof; and at least one mass spectrometry grade solvent. Also provided are methods for analysing a biological sample for the presence of a virus, or an exosome or other extra-cellular vesicle, using MALDI-ToF MS once prepared.

Abstract: The method describes rapid screening of whole blood samples, pin prick and blood spot cards, subjected to MALDI-ToF Mass spectrometry. The spectra is generated and compared to those from normal healthy controls. Characteristic spectra are indicative of the presence of a hemoglobinopathy and the method can be used to screen/diagnose all sickle cell diseases, alpha and beta Thalassemias.
