This property is sometimes described as "Fast Key Erasure" or Forward secrecy. There was an evident erasure of black diasporic roots. Instead, generics classes and methods are transformed during compiling via a process termed type erasure. The generic type information is then removed in a process called type erasure. This pathway is employed in the erasure of CpG methylation (5mC) in primordial germ cells. The Dianetics procedure to achieve this erasure is called "auditing". A similar pattern is also used in secure erasure of media.
