Embodiment Construction

[0017] In the media cleaning standard (NIST 800-88) of the National Institute of Standards and Technology (NIST 800-88), purging data is a data security erasure standard that can resist laboratory-level attacks. However, the present invention achieves the requirement of NIST 800-88 standard for erasing data by using the basic input and output system unit to read the address of the data erasing command (Secure Erase Command) and erasing the data in the data storage unit according to the data erasing command. In order to make the content of the present invention clearer, the following examples are listed as examples in which the present invention can actually be implemented.

[0018] figure 1 It is a flowchart of a data clearing method according to an embodiment of the present invention, wherein the method is applicable to an electronic device, and a clearing command is used to clear data of a data storage unit in the electronic device. And, the clearing command is stored in a ...

Abstract

The invention relates to a data eliminating method and an electronic device for the same. In the method, data of a data storage unit are eliminated by eliminating instructions, and the eliminating instructions are stored in a block of a memory. The data eliminating method comprises the following steps of generating a triggering event; reading the address information of the block of the memory from a basic input and output system unit so as to obtain the address of the block of the memory; reading the eliminating instructions from the block of the memory according to the address of the block of the memory; transmitting the eliminating instructions to the data storage unit; and eliminating the data in the data storage unit according to the eliminating instructions by using the data storage unit. The electronic device comprises the basic input and output system unit, a processing unit, a peripheral chip unit and the data storage unit. By using the data eliminating method and the electronic device, the data can be strictly protected further, and the risk of data outflow is reduced.

Description

【Technical field】 [0001] The present invention relates to a data processing method, and in particular to a data security clearing method and its electronic device. 【Background technique】 [0002] In today's technologically advanced era, electronic devices storing various data have become an indispensable information processing tool in people's lives. In particular, computer systems can meet all the needs of people in work, travel and entertainment. More and more people use computer systems to process various data. For example, data such as personal financial details, financial account passwords, private documents and photos, business documents, and intelligent creations can all be stored in the hard disk of the computer system. [0003] However, with the improvement of computer crime skills and numbers, users will face the threat of leakage of personal privacy data and leakage of confidential documents. Therefore, how to prevent others from arbitrarily opening, tampering o...
