Active and controllable hard disk data deletion method and device without operating system

Abstract

The invention discloses an active and controllable hard disk data deletion method and device that does not require an operating system. Through the scheme of the invention, the security chip and the positioning chip can be combined without an operating system to regularly detect whether a geographical location has occurred. Location-sensitive high-risk events, when a location-sensitive high-risk event is detected, the operating system-independent hardware-level file system parsing algorithm is used to locate the sector where the high-security data is located, and directly analyze the high-security data without an operating system. The sector encrypts and permanently deletes the key, and directly rewrites the random number multiple times on the sector to achieve high-security data deletion in multiple states of power-on / sleep / power-off, thereby realizing the loss of secret-related computers, The data will be automatically deleted when the personnel carrying the secret computer is coerced by force or the personnel of the secret unit are taken away from the secret computer, so as to ensure the security of the secret data.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an active and controllable hard disk data deletion method and device that does not require an operating system. Background technique [0002] The loss of high security level data will bring serious consequences. In order to ensure the security of high security level data, the state has formulated a strict confidentiality system. Make sure to carry it with you when you secure your computer. However, a strict confidentiality system cannot replace confidentiality technology. In special circumstances, data with high security levels may still face a huge risk of leakage. Some scenarios include: [0003] (1) The internal personnel of the unit intentionally or unintentionally take the classified computer out of the secret room; [0004] (2) Staff members who go out with classified computers are coerced by force; [0005] (3) Loss of a confidential computer that was carri...
