## Abstract

As individuals increasingly employ their wireless devices to engage in different types of activities they face a growing threat from, possibly among other things, identity theft, financial fraud, information misuse, etc. and the serious consequences or repercussions of same. Leveraging the ubiquitous nature of wireless devices and the popularity of (Short Message Service, Multimedia Message Service, etc.) messaging, an infrastructure that enhances the security of the different types of activities within which a wireless device user may participate through dynamically configurable levels of authentication. The infrastructure may optionally leverage the capabilities of a centrally-located Messaging Inter-Carrier Vendor.

## Claims

### Claim 1

A method for enhanced security, comprising:
receiving from a third party a request message, the request message indicative of an activity involving the third party and a mobile subscriber;
performing at least one processing step on aspects of the request message, using at least in part information from the request message and definitional information previously provided by the third party, yielding at least an indication of the need for enhanced security; and
responsive to the indication of the need for enhanced security generating at least one notification message to the mobile subscriber, the at least one notification message indicative of one or more levels of necessary authentication.
