Method for secure deletion of data, firmware component and use of a firmware component

摘要

#CMT# #/CMT# The method involves requiring deletion and/or determination of a preset portion of a machine storage system. The requirement and/or the determined portion are transmitted to a firmware component over a firmware interface. A computer system is started (21) such that a system firmware of the computer system is executed (22). The firmware component is stored with a program code for secure deletion of data by the system firmware. The preset portion of the storage system is determined and deleted (27) by executing the code within the firmware based on an operating system of the computer system. #CMT# : #/CMT# An independent claim is also included for a firmware component for a computer system. #CMT#USE : #/CMT# Method for secure deletion of data e.g. document with confidential personal or financial data and outsourcing data, from a computer system. #CMT#ADVANTAGE : #/CMT# The method ensures simple, effective and secure deletion of the data from the computer system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart illustrating a method for secure deletion of data from a computer system. 21 : Step for starting computer system 22 : Step for executing system firmware of computer system 24 : Step for starting operating system of computer system 25 : Step for storing and executing program code 27 : Step for deleting preset portion of storage system.
