Military Technology

Hey, Xiao Wu, how is the situation? Have you verified that the system has really been deciphered? "

Hearing Luo Kai's anxious voice on the phone, Wu Hao smiled and comforted him: "Director, we are still verifying. Don't worry, our system is not so easy to crack."

"Be sure to verify it clearly and give me an answer as soon as possible." Luo Kai said seriously on the phone.

This matter is indeed very 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 has the source code of this system, it means that they can design related viruses to 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 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's your laptop user name?"

"Ah, uh, Sihuo!" The technician froze for a moment, and quickly replied.

Wu Hao nodded and said, "Coco, connect to the computer with the user name Sihuo."

"A connection request is being sent, waiting for the other party to agree."

Wu Hao turned his head to look at the technician when he heard the words, and the technician quickly clicked to agree.

"Capture the video played on the desktop, and analyze and restore the information in the paused screen."

"The video has been captured and is being restored." Coco's words came from the speaker. Immediately, there was a change on the big screen. On the blurry paused screen, blue subtitles suddenly appeared one after another, and then quickly restored line by line.

"Sir, this is a string of artificial intelligence codes!"

Wu Hao looked at the restored code on the screen and thought for a while, then smiled: "Coco, call up the smart voice assistant system template 0019, and compare it with the current code."

"Calling out, comparing!"

The voice fell, and the big screen was divided into two parts. Part of those restored codes that show still pictures,

The other part is the fast-blinking code line interface.

The meeting room was very quiet, and everyone was sitting there staring at the screen and looking at the flashing code, hoping to get the result sooner.

Wu Hao smiled when he saw this, and then took out a cigarette and lit it: "Everyone relax, it's no big deal, our system can't be broken by anyone who wants to."

"Haozi, are you already sure?" Zhang Jun asked him expectantly.

Wu Hao nodded with a smile: "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 an accurate result.

But the atmosphere is a little more relaxed than before, at least the muscles on everyone's faces are not so tense.

"After the comparison of information and data, a total of 13 similar content fragments were found, with the highest similarity of 31.2% and the lowest of 4.5%."

"How much?" Zhang Jun excitedly stood up and said loudly while Wu Hao was still speaking.

"Coco, repeat the result." Wu Hao smiled.

"Okay, information data comparison..."

"How is this possible? Obviously, I feel that it is our code. Why is the similarity so low?" Zou Xiaodong showed an unbelievable expression.

"Feeling?" Wu Hao looked at him dissatisfied and said, "You can't do anything just by feeling, you have to show evidence, like it doesn't mean it is."

"Coco, release the content with the highest similarity for comparison."

"Okay, sir." These two pieces of code are displayed on the screen, one is the restored code, and the other is the original code in their smart voice assistant.

Wu Hao walked up to the crowd and pointed out: "These two pieces of code seem similar, but they are actually completely different things.

The string of code she showed is just a piece of code that is very common in ordinary neural network systems. We also have similar code, but it is not the same as hers. "

"So, she forged it." Zhang Jun said excitedly.

Wu Hao nodded with a smile and said, "I can be sure that this was forged by her."

"But how about the demo video later, the intelligent voice assistant in it is similar to the English version we are developing and testing." Zou Xiaodong still didn't let go of his heart.

"Since this code is fake, then the following part must be fake." Wu Hao said immediately: "Coco, take out the last audio of this video, analyze the sound properties, and judge whether it is natural human voice or intelligently synthesized voice .”

"Okay, the audio track of the video has been extracted, and the analysis is started!" A sound track is displayed on the big screen, and the sound track is a linear pulse coded sound pattern with ups and downs.

Details are gradually revealed as the linear pulse coded sound pattern in the track is zoomed in. On top of the audio track, another audio track is displayed, which is a linear pulse coded sound pattern generated by Coco imitating the sound in the video.

There is also an audio track below, but this audio track is rather messy, and it is the real person's pronunciation drawn by Coco from the database.

Through a series of comparative annotations, it can be seen that the details of the sound track of this video are very different from the image details of the imitation sound track automatically generated by Coco above.

On the contrary, it is closer to the sound track image of the real person below, which means that the conversation between Zhou Yiying and the so-called English version of the intelligent voice assistant shown in the back of this video is all a fake video performed by a real person.

"Let me just say, how can our system be cracked so easily by others." Zhang Jun patted his fat thigh excitedly.

Dong Yiming also let out a long sigh of relief, and then smiled: "That's all right, respond quickly, and release the news before dawn in Europe and the United States."

"Mr. Wu, I'm sorry, we didn't make it 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 your position, and calmness will allow you to find the key to victory."

Speaking of this, Wu Hao said to everyone: "This is a lesson, I hope everyone can seriously learn from the experience.

There will be a lot of things like this in the future. If every thing makes us turn pale with fright, if everything is like an enemy, then everyone in our room will be scared to death. Even if you are not scared to death, you will be exhausted. "
