Header Enrichment using Exomi Mobile Identity
Compared to the widely deployed in-band addition of user identity headers such as PGW/GGSN packet manipulation, WAP Gateways and other header enrichment proxies, the Exomi Mobile Identity solution (XMI) has multiple advantages:
- XMI operates out of band, meaning that it is only consulted when user identity is first established for a session, leading to a massive reduction in capacity requirements compared to in-line traffic analysis and header injection.
- Instead of always pushing the identity through headers whether the service requests it or not, XMI requires services to explicitly request the identity, allowing their behaviour to be tracked and monetized easily.
- The user’s entire browsing traffic does not need to be routed through the XMI system, allowing for distributed data cores, breakout of Internet access closer to the RAN and other network optimizations that are not possible if all user traffic is routed through a traditional header enrichment service.
- XMI is exponentially more secure, with the user’s identity always transferred over SSL-secured and authenticated requests between services and the XMI system. In traditional header enrichment, MSISDNs cannot be inserted into SSL-protected requests, which means that MSISDNs are transmitted to services in an unencrypted format.
- There is no point of failure introduced into the data path by XMI. If for some reason the XMI system were to become completely inaccessible, authentication requests would fail gracefully, but content provider services or mobile browsing would not be otherwise affected.
- XMI supports temporary roaming in a public or home/work WiFi network and other bearers outside the operator’s control, allowing for continued authentication even when the user is not on the operator’s network.
