Title:
A device, a system, a method, and a computer program which eliminate data stored in memory storage
Document Type and Number:
Japanese Patent JP6093014
Kind Code:
B2
Abstract:
An approach for erasing data being stored in a data storage apparatus is provided, which may be provided e.g. as an apparatus, as a method, as a system or as a computer program. A sequence of uncompressible data is obtained fulfilling predetermined criteria, which includes a statistical measure indicative of compressibility or uncompressibility of the sequence of uncompressible data meeting a predetermined criterion, wherein the sequence of uncompressible data is divided into one or more blocks of uncompressible data, the sum of the sizes of the one or more blocks of uncompressible data being larger than or equal to the storage capacity of the data storage apparatus. The one or more blocks of uncompressible data is provided to the data storage apparatus for storage therein to overwrite the data currently stored in the data storage apparatus.
