Real-time comparison and defending method of input data and hardware thereof

Abstract

The invention provides a real-time comparison and defending method of input data and hardware thereof. The method comprises the following steps: firstly, an input device connected with the hardware is utilized to input data into the hardware; the data are recorded and transmitted to the application program of an operating system; the data are processed by the application program to generate result data; a control application program is utilized to receive the result data and name the result data as data to be tested, and the data to be tested are passed back to the hardware; then the reversalprocessing unit of the hardware is utilized to carry out reversal dismantling operation on the result data; and finally, the comparison unit of the hardware is utilized to compare the data and the data to be tested, so as to achieve the aim of utilizing the hardware at real time to judge whether the data results are damaged or not.

Description

technical field [0001] The invention relates to a comparison and protection method and its hardware, in particular to an instant comparison and protection method for input data and its hardware. Background technique [0002] Due to the vigorous development of information industry technology, computers and the Internet have become an indispensable part of people's lives today. Whether it is personal data or company business data, they can be stored through the media of computers and networks. However, due to the popularization of the Internet today, a large number of network hackers have risen, and they have maliciously invaded, destroyed computer systems, tampered with computer internal data and other illegal activities, which have caused considerable harm to computer information security! As a result, many individuals and enterprises have suffered higher and higher losses, so various technologies for maintaining information security and the developed tool software have been...

Problems solved by technology

[0006] Although the characteristics of the hash function can be used to effectively and quickly check which input data has been tampered with, however, the use of this method is not perfect. The program may also be infected, damaged or even tampered with by viruses, causing its function to malfunction and fail to detect abnormalities in the input data, allowing hackers and other criminals to avoid detection and take advantage of the opportunity to invade, destroy and tamper data
