Background
The main task of electronic devices such as computers and servers is to process and store data, and the demand for data security is particularly high in some special industries, such as military, national defense, and business confidentiality. Under certain specific conditions, data needs to be rapidly and physically destroyed, and the data stored in the hard disk after being destroyed can not be recovered permanently, so that the aim of protecting data security is achieved. Data is mainly stored in the hard disk, so data destruction generally refers to destroying data in the hard disk.
The current solutions are:
1. and reserving destruction voltage at certain PIN PINs of the hard disk, outputting the destruction voltage by the system when the destruction is needed, and burning the memory chip by the hard disk by using the voltage so as to achieve the purpose of data destruction.
2. The destruction is usually triggered by the provision of a destruction button, which when pressed or pressed for a long time, outputs a destruction voltage for destruction.
3. In the destroying process, the destroying indicator light is turned on, and the indicator light is turned off after the destroying is finished so as to confirm that the data destroying is finished.
The current solution has the disadvantages that:
1. a person who does not know the characteristics of the computer may inadvertently press the destruction button, destroying the data without the need to urgently destroy the data, resulting in erroneous destruction. Although the destruction button is identified with a protective cover or warning, this problem cannot be completely avoided.
2. Whether the person who has the authority to issue the destroying instruction or not, the destroying is started only by pressing the destroying key, so that data are lost.
3. If the key body is destroyed in an emergency, the data cannot be destroyed, and serious loss is possibly caused.
4. The destruction indicator is not intuitive enough that an unfamiliar operator may not observe it and thus cannot confirm whether the data has been successfully destroyed.
5. The destruction control mode is single, and different customer requirements are difficult to adapt.
6. The physical destruction needs larger power consumption to burn the chip, so the required voltage ratio is higher, generally more than 24V. Most electronic devices do not have high voltage inside, which results in difficulty in implementation.
