"Hey, Xiao Wu, how's the situation? Has it been verified? Is the system really cracked?"
Hearing Luo Kai's anxious voice on the phone, Wu Hao smiled and comforted: "Director, we are still verifying it. Don't worry, our system is not that easy to crack."
"Be sure to verify it clearly 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 designed to carry out attacks. Not only can it steal various data of relevant fighter aircraft, it can even cause the entire fighter system to fail and paralyze. This
It will undoubtedly be a fatal blow to both fighters and pilots.
Wu Hao naturally knew that this matter was of great importance, so he hurried back.
Looking at the enlarged fuzzy code on the big screen, Wu Hao frowned, then turned to the technician sitting in front of the computer and said, "What is your laptop username?"
"Ah, uh, four fires!" The technician was stunned for a moment and quickly replied.
Wu Hao nodded and said: "Coco, connect to the computer with the username Sihuo."
"Sending a connection request, waiting for the other party's consent."
Wu Hao heard this and turned to look at the technician, who quickly clicked to agree.
"Capture the video played on the desktop and analyze and restore the information in the paused screen."
"The video capture is complete and restoration is in progress." Coco's words came from the speaker. Immediately, changes appeared on the big screen. On the blurry pause screen, blue subtitles suddenly appeared one after another, and then a line
Lines can be restored quickly and clearly.
"Sir, this is a string of artificial intelligence code!"
Wu Hao looked at the restored code on the screen and thought for a moment, then smiled: "Coco, call up the intelligent voice assistant system template 0019 and compare it with the current code."
"Calling out, comparing in progress!"
After the words fell, the large screen was divided into two parts. One part showed the restored code in the still picture, and the other part was the rapidly flashing code line interface.
The conference room was very quiet. Everyone was sitting there staring at the screen and looking at the flashing code, hoping that the results would come out soon.
Wu Hao smiled when he saw this, then took out a cigarette and lit it: "Relax, it's not a big deal. Our system can't be broken by anyone."
"Haozi, are you sure?" Zhang Jun said to him with a hopeful face.
Wu Hao smiled and nodded: "Yes, there are some, but just to be on the safe side, let's do a comparison and analysis."
"That's it!" Zhang Jun and everyone breathed a sigh of relief after hearing this, and then continued to stare at the big screen, hoping to get accurate results.
However, the atmosphere was a little more relaxed than before, at least the muscles on everyone's faces were not so tense.
"After comparing the information data, a total of thirteen similar content fragments were found, with the highest similarity being 31.2% and the lowest being 4.5%."
"How much?" Wu Hao still said something, but Zhang Jun stood up excitedly and said loudly.
"Coco, repeat the result." Wu Hao smiled.
"Okay, information data comparison..."
"How is this possible? I obviously feel that it is our code. Why is the similarity so low?" Zou Xiaodong showed an unbelievable expression.
"Feeling?" Wu Hao looked at him and said dissatisfiedly: "You can't just rely on feeling to do anything. You have to provide evidence. Looks don't mean they are."
"Coco, show the most similar content for comparison."
"Okay, sir." Two pieces of code were displayed on the screen, one was the restored code, and the other was the original code in their smart voice assistant.
Wu Hao walked up to the crowd and pointed out: "These two pieces of code may seem similar, but in fact 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 similar code to this code, but it is different from hers."
"So, she forged it." Zhang Jun said excitedly.
Wu Hao nodded and said with a smile: "I'm sure this is what she forged."
"But what about the demonstration video that follows? The intelligent voice assistant in it performs almost the same as the English version we are developing and testing." Zou Xiaodong still didn't feel relieved.
"Since this code is fake, then the following content must also be fake." Wu Hao then said: "Keke, extract the last audio of this video, analyze the sound attributes, and determine whether it is a natural human voice or an intelligently synthesized voice.
.”
"Okay, the video audio track has been extracted and analysis has begun!" A sound track was displayed on the large screen, and on the track was a linear pulse-encoded sound pattern that went up and down.
As the linear pulse coding sound graphics in the audio track are enlarged, the details are gradually revealed. Above the audio track, another audio track is immediately displayed. This is the linear pulse coding sound graphics generated by Cocoa to imitate the sound in the video.
.
There is also an audio track below, but this audio track is messy. It is a real person's pronunciation extracted from the database by Coco.
Through a series of comparison annotations, it can be seen that the details of the sound track of this video are very different from the image details of the imitated sound track automatically generated by Cocoa above.
On the contrary, it is closer to the audio track and image of the real person below. This means that the conversations between Zhou Yiying and the so-called English version of the smart voice assistant shown at the end of this video are all fake videos performed by real people.
"I'm just telling you, how can our system be cracked so easily by others?" Zhang Jun patted his plump thighs and said excitedly.
Dong Yiming also breathed a long sigh of relief, and then smiled: "Okay now, respond quickly and release the news before dawn in Europe and the United States."
"Mr. Wu, I'm sorry, we didn't arrive in time..." Zou Xiaodong was about to explain to him, but he stopped him with a wave of his hand.
"Don't panic about anything at any time, just face it calmly. Fear will only make you lose control, but calmness can help you find the key to victory."
Having said this, Wu Hao said to everyone: "This is a lesson, I hope everyone can seriously learn from it and sum up the experience.
There will be a lot of things like this in the future. If every thing scares us and turns every tree and tree into a panic, then everyone in our room will be scared to death. Even if we are not scared to death, we will be exhausted."
