On the Minimum Cost of Information Erasure for Stationary Memoryless Sources
Naruaki Amada, Hideki Yagi (Univ. of Electro-Comm.) IT2018-17
Abstract (in Japanese) (See Japanese page) 
(in English) In order to erase data including confidential information stored in the storage device, overwriting an unrelated and random sequence is usually performed, which prevents the data from being restored. Recently, the problem of minimizing the cost for information erasure when the amount of information leakage of the confidential information should be less than or equal to a constant asymptotically has been proposed by T. Matsuta and T. Uyematsu. Whereas the minimum cost for overwriting has been given for general sources, a single-letter characterization has been given for stationary memoryless sources only for which confidential information and the data stored in the device are the same. In this paper, we provide a single-letter formula of the minimum cost for overwriting for stationary memoryless sources for which confidential information and the data stored in the device may be different. We calculate the minimum cost for a source and show the relation between the amount of information leakage and the minimum cost for overwriting.
