Chapter 139: False alarm 1

Hey, Xiao Wu, how's the situation? Has it been verified that the system has been deciphered? "
Hearing Luo Kai's anxious voice on the phone, Wu Hao smiled and comforted: "Director, we are still verifying. You can rest assured that our system is not so easy to crack."
"Be sure to verify and give me a reply as soon as possible," Luo Kai said seriously on the phone.
This matter is indeed important. Once it is confirmed that their system has been deciphered, the military may have to re-examine the technology they are currently developing for the sake of information security.
If the other party really masters the source code of this system, it means that relevant viruses can be targeted for attack. Not only can it steal various data of related fighters, but it can even disable the entire fighter system, which will undoubtedly be a fatal blow to fighters and pilots.
Wu Hao naturally knew that this matter was important, so he hurried back.
Looking at the enlarged fuzzy code on the big screen, Wu Ha frowned, then turned to the technician sitting in front of the computer and said, "What is your laptop user name?"
"Ah, uh, four fires!" The technician stunned and quickly returned.
Wu Hao nodded and said, "Coco, connect to the computer with the username Sihuo."
"Sending a connection request, waiting for the other party to agree."
Wu Haowen turned his head to look at the technician, who quickly clicked to agree.
"Capture the video on the desktop and analyze and restore the information in the paused screen."
"The video capture is complete and the restoration is in progress." Coco said from the speaker. Then there was a change on the big screen. I saw the blue subtitles suddenly appear on the blurred pause screen, and then quickly cleared line by line.
"Sir, this is a string of artificial intelligence code!"
Wu Hao looked at the restored code on the screen for a moment, and then smiled: "Coco, call up the intelligent voice assistant system template 0019 and compare it with the current code."
"Recalling, comparing!"
The voice fell and the big screen was divided into two parts. One part shows the restored code for the still picture, and the other part is a fast flashing code line interface.
The meeting room was quiet, everyone was sitting there staring at the screen and looking at the flashing code, hoping to get the results early.
Wu Hao smiled when he saw this, and then he took out a cigarette and said, "Everybody relaxes, it's not a big deal. Our system is not broken by anyone who wants to break it."
"Hirko, are you sure?" Zhang Jun said expectingly at him.
Wu Hao nodded with a smile: "I have some, but I will compare and analyze it for your insurance."
"That's it!" Zhang Jun and the others heard that he was relieved, and then continued to stare at the big screen, hoping to get accurate results.
However, the atmosphere has been lessened than before, at least the muscles in everyone's faces are not so tight.
"Compared with the information data, a total of 13 similar content fragments were found, with a maximum similarity of 31.2% and a minimum of 4.5%."
"How much?" Wu Hao still uttered, Zhang Jun stood up and exclaimed loudly.
"Coco, repeat the results." Wu Hao smiled.
"Okay, information data comparison ..."
"How is this possible? Obviously I feel like our code. Why is the similarity so low?" Zou Xiaodong showed an incredible expression.
"Feeling?" Wu Hao looked at him dissatisfied. "What you can't do by feeling alone, you have to come up with evidence, like it doesn't mean that.
"Coco, put the most similar paragraph out for comparison."
"Okay, sir." The two code sections are displayed on the screen, one is the restored code, and the other is the code originally in their smart voice assistant.
Wu Hao came to the front and pointed at the crowd: "The two pieces of code seem similar, but they are completely different things.
The string of code she showed is just a very common piece of code in ordinary neural network systems. We also have a similar piece of code, but it is not the same as her. "
"So, this is her forgery." Zhang Jun said excitedly.
Wu Hao nodded and smiled: "It is certain that she faked it."
"But what about the later demonstration video, the intelligent voice assistant in it behaves similarly to the English version we are developing and testing." Zou Xiaodong's heart still did not let go.
"Since this code is false, then the following content must be false," Wu Hao said immediately. "Coco, extract the final audio of this video, analyze the sound properties, and determine whether it is natural human voice or intelligent synthesized speech. . "
"Okay, the video track has been extracted, and the analysis is started!" A sound track is displayed on the big screen. The track is a linear pulse coded sound pattern with ups and downs.
As the linear pulse-coded sound pattern in the audio track zooms in, the details are gradually revealed. Above the audio track, an audio track is displayed, which is a linear pulse-coded sound pattern generated by Cocoa to mimic the sound in the video.
There is also an audio track below, but this one is rather messy, and it is a real human voice tuned from Coco's database.
Through a series of comparison annotations, it can be seen that the details of this video sound track are very different from the details of the imitation sound track image automatically generated by the cocoa above.
On the contrary, it is closer to the image of the sound track of a real person below, which means that the dialogue between Zhou Yiying and the so-called English version of the intelligent voice assistant shown behind this video are all fake videos from live performances.
"I'll just say, how can our system be so easily cracked by others." Zhang Jun patted his fat thigh excitedly ~ EbookFREE.me ~ Dong Yiming also breathed a sigh of relief, then smiled: "This is all right, respond quickly, and release the news before dawn in Europe and America."
"Mr. Wu, I'm sorry, we didn't make it in time ..." Zou Xiaodong was preparing to explain to him, but he stopped by waving his hand.
"Don't panic at any time, just face it. Fear will only make you lose your squareness. Calmness will let you find the key to success."
Speaking of this, Wu Hao said to everyone: "This is a lesson, and I hope everyone can seriously learn from their experience.
There will be many such things in the future. If everything surprises us, if everything is a soldier, then everyone in our house must be scared to death. Even if you are not scared to death, you have to be exhausted. "
