Abstract:We describe how the compliance requirements for data retention
from recent laws such as the US Sarbanes Oxley Act may be supported
by a tamper-evident secure storage system based on probe
storage with a patterned magnetic medium. This medium supports
normal read/write operations by out-of-plane magnetisation of individual
dots. We report on an experiment to show that in principle
the medium also supports a separate class of write-once operation
that destroys the out-of-plane magnetisation property of the dots
irreversibly by precise local heating. The write-once operation
can be used to support flexible data retention by tamper-evident
writing and physical data deletion.
