Data retention policies must be formulated in the context of the need for �social forgetfulness�, a term which encompasses a fundamental base for most modern societies where individuals are to �forget� past indiscretions having made good their failings. This is particularly important in areas such as bankruptcy, juvenile crime records and credit reporting. The natural follow-up of having constraints on the retention of data is of course the destruction of what is no longer relevant or necessary to be kept.
The thesis will focus not on the actual destruction techniques but on the standard of the destruction i.e. the destruction of data to the point that it is unrecognizable, untraceable and unusable.
