## Abstract

The present invention relates to systems and methods for matching and collecting user data and/or user device data within a current Internet access session of a user for use by user notification systems that generate, distribute and display informational messages over the Internet. The system comprises a source data reception unit configured to receive a source IP address and a source user device port matched with the translated IP address and with the translated port of the operator or the provider from the NAT service, and a data matching unit configured to match user data and/or user device data from all available sources, including but not limited to operator or provider databases, using the received source IP address and the received user device port. Advantageously, the invention provides delivery of informational messages based on collected/matched user data and/or user device data provided according to the present system to the maximum number of real identified users.

## Claims

### Claim 1

A system for matching and collecting user data and/or user device data within a current Internet access session of a user, the system interacting with an operator device or a provider device and configured to operate outside an operator network perimeter or a provider network perimeter and used for a user notification system that generates informational messages in real time, the system comprising:
a query reception unit configured to receive a user data query from the user notification system, the user data query containing a translated IP address and a translated port of the operator or the provider,
a query direction unit configured to direct a query containing the translated IP address and the translated port of the operator or the provider to a service of the operator device or the provider device, the service comprising the NAT service carrying out network address translation (NAT),
a source data reception unit configured to receive a source IP address and a source user device port from the NAT service, the source IP address and the source user device port being matched with the translated IP address and with the translated port of the operator or the provider, wherein the source data reception unit configured to receive a source IP address and a source user device port from the NAT service using a NetFlow or IPFIX protocol,
a data matching and collection unit configured to match user data and/or user device data from all available sources, including but not limited to operator or provider databases, using the received source IP address and the received source user device port, and to collect the matched data user data and/or user device data from said available sources; and
a collected data directing unit configured to direct the collected matched user data and/or user device data to the user notification system.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the data matching and collection unit is configured to determine a unique user identifier (UID) and to determine data corresponding to the UID based on the source IP address and the source user device port.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the data matching and collection unit is configured to match the data matched using the source IP address and the source user device port stored in a first database with data stored in a second database.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the available sources include various means and enterprise information systems (EIS), including but not limited to: browsers, download managers, mobile and desktop applications, customer relationship management (CRM), data management platform (DMP), deep packet inspection (DPI).
