Header Enrichment using Exomi Mobile Identity
Compared to the widely deployed in-band addition of user identity headers such as the PGW/GGSN packet manipulation, WAP Gateways and other header enrichment proxies, Exomi Mobile Identity solution (XMI) has multiple advantages:
- Operates out of band where the XMI 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 it’s requested or not by the service, services explicitly request the identity allowing their behaviour to be tracked and monetized easily
- The user’s entire browsing traffic is 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 which 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 a SSL-secured and authenticated requests between services and the XMI system. In header enrichment, MSISDNs cannot be inserted into SSL-protected requests leading to MSISDNs being transmitted unencrypted to services.
- There is no point of failure introduced into the data path by the XMI. If for some reason the XMI system were to become completely inaccessible, authentication requests will fail gracefully but content provider services or mobile browsing will not be otherwise affected.
- XMI supports temporary roaming to public or home/work WiFi and other bearers outside the operator’s control to allow for continued authentication even when not on the operator’s network.
