Hu Yifei arrived at the technical section of the Public Security Bureau, Captain Li and the chief of the technical section were smoking in the corridor at the door, and when they saw Hu Yifei, the two joked and said, "Let a high-tech billionaire come to repair our computer, this time it's too face-saving!" "Don't forget to pay your salary!" Hu Yifei simply followed the words of the two and joked to himself. [Full text reading]

"If anyone's wages are missing, then I don't dare to owe Mr. Hu's wages. You belong to the big names, although there is no shortage of money, but if you are owed wages, I estimate that the tabloid reporters can tear down the wall of our city bureau! The chief of the technical section smiled and asked Hu Yifei to come in and speak.

The three of them went into an office, and inside was a workbench with five or six monitors, large and small.

"That's the working platform for that blurry image recognition system! , the head of the technical department introduced Hu Yifei to "These software vendors are very treacherous, and they are afraid that the software will be cracked, so they don't send us to install the program." Want to buy his software,... It must be bought with software and hardware. Oh, it's this table, and it's flown in from the Netherlands! The section chief shook his head, very helpless.

Hu Yifei smiled: "I've never seen such a domineering teaching dealer!" ”

"There is no way, at present, there are only two sets of fuzzy video identification software that is generally recognized in the world and can be directly used as forensics, one is designed in the United States and the other is designed in the Netherlands." The section chief turned on the computer in front of him and continued, "People do their own business, so they dare to be domineering. At the beginning, we talked about the condition that the installation program should be complete, and the system environment was built by ourselves, and people did not refuse, but the asking price was 540,000 US dollars, and it was a fixed price. We don't have so much money in the bureau, so we have to settle for the next best, Tian Wan, and buy two sets of overall systems. As I spoke, the computer booted up, and after entering the desktop, the video recovery software immediately run, but soon a prompt box popped up, saying that it lacked the necessary files required for the running environment and could not be started.

Hu Yifei glanced at it and said, "Look at the prompt, it should be a set of anti-cracking and anti-reverse editing and interpretation monitoring system running in the system, and now the files of the monitoring system are damaged and cannot be started, which causes the video recovery software to fail to start."

This set of video recovery software, when it is launched, may be pre-analyzed in the operating environment, and it will only run if the anti-cracking mechanism is activated. ”

The section chief coughed twice and said, "I guess that's what happened!" If a system is so complicated, can it not go wrong in three days? ”

Hu Guifei smiled, he had already roughly guessed the reason, it must be that after the software was bought, the people in the technical department tried to crack it, and wanted to transplant this set of software, but they didn't get the anti-cracking system set up by the other party, but they were solved by this anti-cracking system.

Since the software vendor is sold together with the hardware, the other party's anti-cracking system must be based on the hardware, and if you want to crack it, it is so easy, and even the software in front of you can only run on this computer, and if you change it to any other computer, it will not be able to run, because this radish can only be planted in this pit.

"Xiao, Hu, look at it, is there a way to make it run again?" Captain Li looked at Hu Yifei.

Hu Yifei shook his head, "It's too difficult, I'm afraid I have to ask the software vendor to send someone to fix it!" ”

The section chief and Captain Li glanced at each other, both with sad faces, they cracked other people's software, how could the software vendor be willing, the maintenance cost was naturally more ruthless than the previous time, and after coming, it was even more aggressive and sneering, if he said it, the people who could be ashamed of the technical department couldn't eat for three days, and the old face burned like a monkey's buttocks.

"Isn't there any other way?" Captain Li asked, "The maintenance fee we have sent in the past two years is enough to buy a new system, and then send it and the city bureau will close it directly!" Hu Yifei pondered for a moment and said, "I'll try my best, but I can't guarantee that it will be done!" ”

"Anyway, it's already broken, and the dead horse is treated as a live horse doctor, you can just get it with your hands!" The section chief looked indifferent, he had prepared for the worst, he really couldn't, he applied to the bureau, and introduced another system from the United States, anyway, he would never let the Dutch software vendor repair it Captain Li also said, "That's it, you don't have to worry, just get it, it's okay to dismantle this machine!" ”

Hu Yifei smiled helplessly, and said in his heart that it has been broken, so you dare to say that, if the system is normal, I want to touch it, and you are afraid that you will not be willing. At the moment, he shook his crotch very handsomely, put the p tool kit in front of him, opened it and flipped it over, pulled out a disc, and the whole set of actions was done in one go. The line is smooth, and it is worthy of doing this business. The kit on his body is still the equipment he used to use when he was in Weilan, but unfortunately he hasn't worked by himself for nearly half a year, and when he came out today, he casually flipped through it and turned it out again.

Hu Pufei bent down and looked at the computer case, dumbfounded, "What about the disk machine?" "No disc player!" The section chief spread his hands and smiled.

"How do you fix it when someone from a software vendor comes?" Hu Fei asked rhetorically.

"The case is locked with an electronic lock, and when they come, they open the box, connect the external disk drive, and then recover! A section chief.

Hu Yifei vomited blood directly, in order to repair it, the system, he can't do the work of cracking the electronic lock, besides, the electronic lock is not to say that it can be cracked, that thing is connected to the motherboard, the password is entered a few times, and the entire motherboard is locked, and the computer cannot be started.

"Why don't you open the box!" The section chief suggested.

"No need! , Hu Yifei waved his hand, "Without Zhang Butcher, is it possible that you really want to eat hairy pigs?" Hu Yifei didn't know the section chief's worst plan, he was afraid that he would really force the box, in case he couldn't figure out the system, then he would find someone from the software vendor, and it would be a problem whether they would repair it or not.

"Let's open the box!" The section chief once again suggested that Erhu Yifei still didn't care, and said, "Then how did you get the video that you usually need to recover into this machine?" ”

"There are specialized machines to do this job!" The section chief pointed to another very inconspicuous machine next to the workbench, and said, "There is a software on this computer, which can be linked to the video recovery platform, and the two are linked by a private agreement, and only videos and pictures can be uploaded, when we need to recover blurry videos and pictures, we will put the video into this computer, and then upload it to the work platform through this software, and then you can take it on the platform, and then the results returned will also be taken out on this computer." As the section chief spoke, he lit up a small monitor on the workbench dagger, and Hu Yifei realized that there were two computers here.

However, the section chief said again, "Now the Zupin recovery platform cannot be operated, so this computer cannot establish a connection with the working platform!" "It's okay, that's it!" Hu Yifei smiled: "Save me from being rough again!" He has a lot of ways to get his own documents on this workbench, these methods are similar to the way he used sound waves to steal the Golden Dragon file at that time, but since people have a special upload method, Hu Yifei saved a lot of work, and then Hu Yifei copied the tools on his disc to the computer soil, and when he was done, he got out of the way, and smiled at the section chief, "I have to trouble the section chief to upload this tool to the work platform!" The section chief was stunned for a moment, at a loss.

Captain Li laughed, patted the section chief, and said, "Okay, don't pretend, people Xiaohu has already seen through your tricks!" The section chief smiled embarrassedly, very embarrassed, he didn't expect to crack this system, so that Hu Yifei saw through, rubbed his hands at the moment, ran ten software on the work platform, and then ran the software for uploading, after a few seconds, it showed that the connection between the two was successfully established, and the section chief then selected Hu Yifei's tool and began to upload.

Hu Yifei smiled, stood aside, but didn't say anything, just now the section chief finally mentioned this software for uploading, Hu Yifei probably guessed a little, since the people of the Public Security Bureau can break the anti-cracking mechanism on the work platform, it proves that they have a way to bypass the upload restrictions set by the software vendor, and upload the tool used for cracking to the work platform.

After two minutes, after the upload was completed, the section chief said hehe twice, rubbed his hands and stood aside, his face was still a little uncomfortable.

Hu Yifei found his own tool on the work platform, and then ran it, the tool popped up a prompt, Captain Li didn't see what was written on it clearly, Hu Yifei pressed, OK, button, the tool then popped up a progress bar, it seemed to be collecting some information, and when the progress bar came to the end, a prompt box popped up again, Captain Li still didn't see it clearly, Hu Yifei quickly pressed the cancel button, and then the computer began to restart.

"Xiaohu, what do you do with this tool?" Captain Li couldn't hold back his curiosity, so he asked a question to collect information about all the hardware, and then rebuild a virtual hardware environment that was exactly the same! Hu Yifei explained.

"So, what is the cancellation?" Captain Li persevered, "Because the software environment on this machine has been destroyed, there is no need for a virtual software environment!" As he spoke, the computer finished restarting, and the prompt that the image recovery software failed to run popped up again, Hu Yifei clicked it off directly, and said, "Now, as long as the correct software environment is virtualized, this software can run, but it can only be done manually, and it is estimated that it will take some time!" After speaking, Hu Yifei pressed a key, and an operation interface popped up on the screen, which displayed the prompt message that the software had failed to run just now.

Hu Yifei frowned, looking very headache, and said, "I haven't done this work for a long time, start work!" ”
