The Live Broadcast Teaches Lockpicking, The Police Pay Attention To Me!

I got a positive answer from Chen Yong.

Su Chen smiled slightly.

"Okay, let's get started!"

After speaking, Su Chen put his ear close to the safe, lightly touched each button of the anti-theft lock with his hand, and began to debug one by one.

Afterwards, Su Chen stretched out his finger, facing the phone screen and explaining to the netizens.

"Family, everyone is optimistic. The feature points of our human fingerprints are classified into: terminal points, bifurcation points, bifurcation points, isolated points, ring points, and short lines; and the ridges of fingerprints are the ridges corresponding to the feature points of fingerprint points. Wire."

"The ridge line corresponding to the feature point is represented by the sampling point on the ridge line."

"The sampling point of the fingerprint sensor is represented by the distance between the point and the corresponding feature point, the straight line connecting the point and the corresponding feature point, and the angle between the direction of the corresponding feature point."

"So we say that everyone's fingerprints are unique. Without fingerprints, it is almost impossible to open the fingerprint lock."

"And our common fingerprint identification system is called 'optical fingerprint identification system', which uses light reflection imaging to identify fingerprints. This type of fingerprint module has certain requirements for the temperature and humidity of the use environment; the fingerprint identification button on the mobile phone, In fact, it is a capacitive fingerprint module, which uses the silicon crystal element and the conductive subcutaneous electrolytic solution to form an electric field, and the fluctuation of the fingerprint will cause different changes in the pressure difference between the two, so that accurate fingerprint determination can be realized."

Su Chen talked eloquently, and all the netizens adored him.

[Can it be understood that to learn how to pick a lock well, one must also learn biology and physics well. 】

[Upstairs, remind you, there is also mathematics! 】

[Why do I feel that the distance between me and the lock is getting farther and farther. 】

...

"The anti-theft lock on the safe we ​​see now uses the most advanced biometric radio frequency fingerprint identification system. The accuracy of this device is very high."

"It emits a small amount of radio frequency signal through the sensor itself, penetrates the skin layer of the finger to control the inner layer of the texture, and obtains the best fingerprint image."

"The identification principle of the fingerprint sensor only responds to the human skin, so this radio frequency technology is widely used in the identification system of the police."

【ah? ? ? Only reacted to the dermis, so how to find that person now? 】

[This degree of difficulty is really too high! 】

[I am very worried that the anchor will not be able to complete the task. 】

...

Facing the speculation of netizens, Su Chen was very calm.

In fact, from the moment he touched the fingerprint lock just now, he had obtained all the superpowers to open the lock.

His brain was running fast.

Regardless of the way the fingerprint is collected, the collected information is not a picture of the fingerprint, but a string of codes calculated by a special algorithm.

Just like fingerprints are arranged and combined to form a corresponding barcode. If the reverse comparison is performed, it can be calculated whether the two fingerprints come from the same person. Generally, there are four steps.

From fingerprints to fingerprint feature points to fingerprint feature maps to a string of digital symbols.

Su Chen watched the keypad on the fingerprint device with his eyes, and scanned the fingerprint keypad on the fingerprint combination lock.

Immediately, he quickly completed the collection of fingerprints on the fingerprint device.

Su Chen began to input digital language in his brain based on the fingerprint features extracted from the fingerprint device, and then programmed and analyzed.

In Su Chen's mind, a powerful algorithm appears overwhelmingly, like a stream of current, to mathematically convert the collected fingerprint endpoints, bifurcation points, bifurcation points, isolated points, ring points, short lines, etc., and Save them one by one in the database in Su Chen's mind.

After just a few minutes, Su Chen has calculated the corresponding fingerprint model in his brain.

Su Chen opened his eyes.

Go back to the front of the safe.

Re-gazing at the fingerprint buttons on this safe with eyes and matching with pupils.

Sudden!

A surprising scene appeared!

The reaction blue light on the fingerprint sensor button starts to flash layer by layer!

With a bang, the door of the safe opened automatically!

Impressively placed inside are pictures of a beautiful woman and a handsome man.

[Fuck! real! It can be true!]

[The anchor did not use any tools or electronic equipment. 】

[I can see clearly. 】

[Boss, absolutely boss! 】

[I suspect that the anchor is an artificial intelligence. 】

The broadcast room suddenly boiled.

then.

[Wait, the man in the photo doesn't look like Mr. Chen! 】

[Let me take a look at it, Mr. Chen is green? 】

[It's the boy who did it! 】

[The color on the top of Mr. Chen's head has changed a little at this time! 】

[Green Green Grassland? 】

...

Facing the ridicule from netizens, Chen Yong was numb.

At this time, his face was blue and purple.

Some become angry from embarrassment.

He never expected that his wife, whom he loves so much, would be forced to do such a thing by himself.

It was also seen by netizens all over the country.

Chen Yong really wants to cry but has no tears.

at this time.

Su Chen closed the safe that had just been opened and closed it again.

? ? ?

Chen Yong looked at Su Chen in bewilderment.

At this moment, Su Chen didn't speak, but put his hand on Chen Yong's shoulder and patted him lightly.

"The anti-theft lock is easy to open, but the heart lock is difficult to open."

"Throw away this safe!"

"It's like opening your own heart lock!"

...

Chen Yong's consciousness gradually came to his senses.

I heard Su Chen say that.

He looked directly into Su Chen's eyes and remained motionless.

Suddenly, he seemed to be enlightened.

"Su Chen, thank you! Helped me unlock my heart!"

Chen Yong held Su Chen's hands tightly in gratitude.

He turned his head and shouted towards the door.

"Come on! Throw me this safe!"
