Embodiment Construction
[0070] The technical solutions in the embodiments of the present invention can be used in many general-purpose or special-purpose computing device environments or configurations. For example: in electronic equipment such as personal computers, server computers, handheld devices, portable devices, tablet devices, and multiprocessor devices.
[0071] Please refer to figure 1 As shown, may include but not limited to: first processor 101, second processor 102, storage device 103, I / O control 104, I / O interface 105, communication device 106, antenna 107, power supply device 108 and display screen / touch screen 109 . The first processor 101 and the second processor 102 are two independent processors, respectively connected to other devices in the electronic device.
[0072] Wherein the first processor 101 is used to run an operating system, and the operating system includes a startup program, a data processing program and a driver program. After the operating system is started, th...

The present invention provides a data protection method, device, and electronic equipment, wherein a data protection method includes: a second processor acquires a first input operation and first data; according to the first input operation, generates a the first instruction; executing the first instruction on the first data to obtain the second data; directly sending the second data to other devices connected to the second processor. Since the second processor runs before the operating system enters the startup program, and the second processor is independent of the first processor, when it performs security processing on the first data, it can run independently of the operating system, so that other people cannot rely on open The operating system tampers with the first data obtained by the second processor, thereby improving data security. Further, the second processor directly sends the obtained second data to other devices connected to it, and this sending process does not go through the operating system, so data security is also maintained.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a data protection method, device and electronic equipment. Background technique [0002] With the popularization of electronic devices and the emergence of new electronic devices, such as wearable electronic devices, electronic devices can obtain various types of data, including: physical signs data, geographic location data and multimedia data, etc., and store these data in electronic devices middle. [0003] In order to improve data security and prevent hackers from obtaining it, electronic devices use encryption algorithms to encrypt data before storing it. Before displaying the data, it needs to be decrypted first, and after the decryption is successful, the data is sent to the display for display. [0004] However, at present, the encryption and decryption of data by electronic devices is completed by the operating system, and the operating system is an open system...
