Abstract: | The government has plans for electronic ID cards, passports and vehicle identification. In industry, smartcards, intelligent
tickets, RFID and active tags are increasingly available at low cost. Technology that was not originally designed for identification
and tracking is now being used in that role. Wi-Fi tags are now available, and a number of technology vendors provide Wi-Fi
location-based services. We are seeing a proliferation of user and object identifiers (more correctly termed ‘identifying
tokens’) that can be read at a range. Barriers between the physical and information world are disappearing and contactless
identifiers promise great benefits for their users. Identifiers can be read at high speeds and low cost without human intervention.
The convergence of technologies causes an increased number of players to rely on identifiers that are reused in multiple domains
and contexts. The result is that the user loses control over their identifiers, and security and privacy vulnerabilities affect
the value of the identifiers to applications. In this paper, we describe what we mean by identifier security, and discuss
the options available to the system designer to mitigate the security and privacy risks. We remark on the lack of a common
regulatory framework for the control of identifiers, and suggest that technology should be used to provide the first and best
layer of defence. |
