SIM: Security Identity Mobility

Week 25, 2011

At the beginning the SIM was just what its name implies, an easy means to identify the subscriber. Over time mobile communication became more complex as new functions have been added.

Our handsets are now full of various apps, and each application brings its own requirements in terms of security. The SIM is the way to handle all these requirements.

Now, with the advent of social networks access from mobile phones, SIM cards play a role in privacy, as they bring the means for the user to decide to whom and how he will share his personal information.

At the same time mobile wallets are emerging in multiple countries. For instance, Everything Everywhere, Telefonica UK and Vodafone UK announce the launch of a joint venture to propose a SIM based mobile wallet to their subscribers (cf. Focus). This, along with the NFC deployment planned by Orange UK and Barclaycard (cf. Smart Insights Weekly #11-21) will ensure a global roll out of NFC in the UK. And, again, the SIM, in a new incarnation is providing the base for secure mobile payments.

Even if the embedded SIM (cf. SIW #10-47) threat is not warded off yet, the physical SIM still has a bright future.
