Digital Identity
 A concept that links a „token“ from the
digital/syntactical world to an object in the
real/semantical world
 Accompanied by a set of properties and
attributes
Mobile Identity
 GSM provides the foundation for a mobile identity
 Subscriber Idententity Module (SIM)
 A mobile identity in this definition is inherently
related to the mobile network operator business
 Represents contract between subscriber & network
operator
 Authorizes subscribers to use the network
 Lets subscribers authenticate themselves
 863.6 Mio GSM subscriptions (IDs) (05.2003)
 More countries with SIM infrastructure (197, May
2003) than with McDonald’s (119, Aug 2003) and more
than UN member states (191, Aug 2003)
SIM within the Network
Mobile Situation providing Attributes
 Mobile networks are able to determine
– The identity
– The position of the user
– The time of usage
Who?
Where?
 That information can be extended
When?
multilaterally by using databases
 Example result: „Customer is 29 years old, student,
in the downtown of Munich, at holiday...“
 The available user’s situation is valuable when it
comes to ad-hoc relationships between customers and
service providers

Current Approach for
M-Commerce Business Models


Mobile Network Operators provide their customers with mobile
portals as access concept for mobile services.
Revenue models with two revenue sources:
– Mobile Data (Internet Service Providing)
– M-Commerce Services (by Service Providers)


Only services providing immediate value for customers.
Services with primary value for Service Providers are currently
not feasible (Advertising, Customer Loyalty Programs etc.).


Size of the German market for mobile telecommunications was
€ 18,4 billion in 2002 [RegTP]
There are more mobile than fixed lines
Penetration rate in December 2002 was 71,7% [RegTP]
Saturation of the market can be observed
Investments in future mobile infrastructure for 3G und wLAN
(licence, capital costs, infrastructures, devices etc.)

Sponsoring Mobile
Customer Relationships

Sponsoring data transmission costs by the service provider is
currently not possible
– Each usage is related with costs for the customer
– Costs are not transparent


Objective: Eliminating data transmission costs for the customer
and transfer them to the service provider
Through mobile initiated business, financing of the data
transmission costs by the service providers shall become possible


Identity-Management-Platform: Self-administration of the
“mobile identity”(personal data and security profile)
Potential customers of enterprises are provided with a free of
charge access to mobile services.
Customers use the mobile portal to choose from a number of
free-of-charge and priced services.
Current business model is extended and not replaced!
Objective: More customers and providers (traffic) on mobile
portals. Charging is done according to the value proposition and
includes customers and Service Providers.
THANK YOU FOR YOUR ATTENTION!
