Embodiment 1

[0068] An information processing method is provided in Embodiment 1, which is applied to an electronic device including a hard disk device and a software system, the software system includes a BIOS (Basic Input Output System), and the hard disk device includes A serial peripheral interface memory, that is, a ROM using SPI (SerialPeripheral Interface—Serial Peripheral Interface) technology, that is, SPI ROM. Because the sending interface and the receiving interface of the SPI interface have their own data channels and flow control status information channels, data can be transmitted quickly and accurately. SPI ROM is used to store data related to the BIOS system of electronic equipment, such as: system upgrade data, system configuration parameters, etc. The electronic device may be a desktop computer, a notebook, an all-in-one computer, a tablet computer and other electronic devices, which will not be listed one by one in this embodiment.

[0069] Please refer to figure 1 , a...

Embodiment 2

[0095] Please refer to Figure 5 , the embodiment of the present application also provides an electronic device, including:

[0096] Housing 501;

[0097] The serial peripheral interface memory 502 is set in the housing;

[0098] a storage unit 503, arranged in the housing, for storing at least one program module;

[0099] At least one processor 504 is arranged in the housing, and the at least one processor obtains and runs the at least one program module to obtain at least one security data when starting the basic input and output system of the electronic device, The at least one security data is data related to security verification during the startup process of the basic input output system; the at least one security data is stored in the first preset storage space of the serial peripheral interface memory; The first preset storage space is latched so that the first preset storage space is switched to a locked state, wherein when the first preset storage space is in the ...

Embodiment 3

[0118] Please refer to Figure 6 , the embodiment of the present application also provides an electronic device, including:

[0119] The first obtaining unit 601 is configured to obtain at least one safety data when starting the basic input and output system of the electronic device, the at least one safety data is data related to safety verification during the starting process of the basic input and output system;

[0120] The first storage unit 602 is configured to store the at least one security data in a first preset storage space of the serial peripheral interface memory of the electronic device;

[0121] The first processing unit 603 is configured to perform latch processing on the first preset storage space, so that the first preset storage space is switched to a locked state, wherein, when the first preset storage space is locked state, the first preset storage space prohibits reading and writing data.

[0122] Optionally, the first acquiring unit specifically includ...

Abstract

The invention discloses an information processing method and an electronic device. The information processing method comprises the steps of obtaining at least one piece of security data when a basic input output system of the electronic device is started, wherein the at least one piece of security data is the data related to security verification in the starting process of the basic input output system; storing the at least one piece of security data in a first preset storage space of an external interface memory; and latching the first preset storage space, thereby switching the first preset storage space to a locking state, wherein when the first preset storage space is in the locking state, data is forbidden from reading from or writing in the first preset space. According to the method provided by the invention, the technical problem that in the prior art, the cost required by a mode for storing the security data in the electronic device is relatively high is solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] Currently in the era of rapid development of electronic technology, electronic devices such as desktop computers and notebooks have been fully popularized. In the existing technology, users will set some security data in electronic devices to confirm access rights to electronic devices, such as: electronic devices Power-on password, electronic device administrator password, system startup password, basic input and output system startup password, etc. These security data are usually stored in a dedicated chip on the motherboard of the electronic device, so that when the user turns on the electronic device, the electronic device can call The safety data is verified for safety. However, since a chip for storing security data must be specially provided on the motherboard, the cost of the ele...
