Turing Forbidden Zone

The supervisor of the Southern Cross Bank is named Richard Grinder.

When he was just 40 years old, he became the security director of this multinational bank, which is indeed unique.

Especially vigilance on safety issues prompted him to choose to completely isolate himself from electronic products until the end of the last 2-hour dangerous period.

2 hours left.

It was 10:10 am Beijing time, a morning destined to be unusual.

The students of University D found that Shi Ye did not come to class on time, which was very rare for him.

After school time, Chu Yingzong excitedly waited outside, but Shi Ye was nowhere to be seen.

He grabbed Wang Gu: "What's going on, I haven't seen Shi Ye for several days!"

Wang Gu said tremblingly: "Brother Ye hasn't returned to the dormitory for 3 or 4 days. It seems that he has something to do when he goes out. He should ask the teacher for leave."

Chu Yingzong then asked a few more students, but they didn't expect them to look at each other, and they didn't know what Shiye was doing.

"...Where can I go? Why didn't I even say a word?"

Chu Ying walked out of the teaching building, glanced at the sky in confusion, and lowered her head to send text messages on her mobile phone.

[Chu Yingzong: Where are you? 】

[Chu Yingzong: Are you awake?Is there any danger? 】

[Chu Yingzong: I'm going to call the police. 】

[Chu Yingzong: Answer me. 】

The message arrived on Shiye's cell phone.

It was placed in the corner, and the screen occasionally lit up once or twice, which did not catch the owner's mind.

This is in a dark room, the headlights are not turned on, and only the cold light of the screen reflects the empty scene.

A one-stop server stands in the center of the room, and the data cables connected to it are messy and messy, connected to Shiye's notebook.

Meanwhile, Shi Ye was sitting in front of the notebook, browsing all the social information on the page about security director Richard Grinder.

On Facebook, Richard Grinder has his own label, which includes some of his own Moments content, and others @ his news, and his name was even included in the promotion of Southern Cross Bank.

From a close-up picture, it can be seen that Richard Grinder has a typical Latino appearance and a pair of dark green eyes.

The high-definition cameras of modern cellphones are powerful enough to snap 2000-megapixel photos, recreating the exact face of the executive — including his eyes — on the web.

in the field of cryptography.

Iris recognition is considered to be an expensive, high-security, but slightly less-accurate authentication device. It mainly recognizes the features on the human iris, converts them into two-dimensional Gabor wavelets to subdivide and reorganize, and compares them. certified.

But no matter what the algorithm behind it is, the initial acquisition is to scan the iris of the human body through infrared rays to complete the first step.

……

At 10:19 Beijing time, Shi Ye got the Grinder's iris image through a high-definition original film on social networks.

In the process of searching for photos, he made more discoveries.

One of Facebook's features is to automatically recognize faces in photos uploaded by users and add corresponding name tags to the faces.

And 67 days ago, in a picture of a completely unrelated person, Grinder was walking not far away in the background—thanks to Facebook’s face recognition technology, he was accurately labeled as Richard Grinder, Appeared in Shiye's search range.

According to the time on the original stamp of the picture, it can be seen that the Grinder passed by at 3 pm.

In the photo, Grinder is still straightening his tie with one hand, so he should have just left the house.

Judging from the news data on the official website of the Southern Cross, Grinder did not take a vacation that day, and there was a press conference at 3:30 pm in which he participated.

Since Grinder is not in the car at 3:[-], but is walking, it means that his starting point is not far from the destination bank.

Calling up Google's traffic records on this day every night, it is easy to see the traffic conditions at that time and the map around the bank-the neighborhood is a well-known wealthy area.

But Grinder's name didn't appear when searching for the corresponding property. It seems that he doesn't live here, and he may have a lunch break at a friend's house that day.

Beijing time 10:41.

Shi Ye completed the writing of the crawler script.

All homes within a 10-minute walk from the original photo's GPS location were included in the review.

Thanks again to the well-developed social network, these residents have a residential circle of friends.

The crawler script scraped all the social content of all residents in the last 3 years in just 3 minutes, but did not find any related content of Grinder.

This is strange.

But it's not enough for Shiye to give up.

Shi Ye patiently and meticulously flipped through the photos of the day, and finally noticed a woman named Lilith.

She posted a circle of friends at 1 p.m. that day. In the photo, she took a selfie in front of the bathroom mirror, in a very sexy pose.

But of course this is not the point, the point is: the toilet seat was turned up.

According to her past content, she is currently single and living alone.

There is no male resident in the house, but only the male will need to turn the toilet seat up.

Shi Ye's script picked up all the public photos of Lilith.

In a photo taken 109 days ago, she posted a photo of her drunkenness. The house was in a mess, and at least twenty beer bottles were tilted on the table.

Shiye zoomed in on the picture and found a gold watch in the messy crevice of the sofa - Grinder once wore this watch at a press conference 32 days ago.

Continue to zoom in on the picture, and you can see the delicate reflection of each beer bottle in the morning light in the original high-definition film.

He compared them one by one, and found a fingerprint on the neck of one of the beer bottles, which was obviously from a male finger.

Through the precise operation of image processing software, the fingerprint in this photo can be removed from impurities, noise interference, flattened into two dimensions, and then reproduced as a usable fingerprint.

At 11:14 Beijing time, after the iris, Shi Ye obtained the fingerprints.

Next you will need a sound and a password.

It's completely unnecessary to try to call the Grinder's phone number.

Security directors at this level will not accept any external risks at this time.

Shi Ye didn't know that Grinder had actually thrown his phone into the pool, but he wasn't even going to try it.

The voiceprint recognition system used by Southern Cross Bank comes from an American company that specializes in voiceprint recognition technology.

Shiye patiently browsed the features of this product, and saw that their voiceprint recognition accuracy rate is as high as 99.1%, but to achieve this accuracy rate, users need to say some unique words, the most typical example is: "I It's xxxx."

Because each person's voiceprint will change according to the actual situation, to improve the accuracy of voiceprint recognition, we need some languages ​​that are as stable as possible and have more personal characteristics.

Right now, Shiye is looking for the Grinder's audio.

There are many videos of Grinder on social networks, and obviously in the news, but within a short period of time, he couldn't find a sentence of "Hello, my name is Grinder"-he didn't need to introduce himself like this in public.

Time and night's exploration has come to a brief standstill here.

……

Beijing time at 11:36 am.

Chu Yingzong had already strolled all the way to the gate of the police station. He was seriously thinking: Did Shiye faint somewhere?Was robbed?Lost and lost?

I heard that some people with Asperger's disease really have severe road blindness...

Just a second before Chu Yingzong made up his mind, his cell phone vibrated suddenly.

[Shi Ye: I have a question. 】

Chu Yingzong: "..."

crackle.

Big veins burst out on Chu Yingzong's temples, and he viciously poked his phone screen with his fingers, as if he had a deep hatred for it.

[Chu Yingzong: You still know how to reply to messages! ! ! ! ! ! ! 】

[Chu Yingzong: Where did you die! ! ! ! !Do you know that I am super worried! ! ! ! ! ! ! ! ! ! 】

[Shi Ye: There was a man who would sleep at a woman's house during his lunch break at work, and would drink with her until dawn.However, this woman is very careful when posting on Moments, and he will never appear.In addition, her source of income as a teacher should not be enough to cover her rent. 】

[Chu Yingzong:? 】

[Chu Yingzong: What do you mean, adopting a mistress? 】

【Shi Ye: You're right.She is his mistress. 】

[Chu Yingzong:? ? ? ? ? ? ? 】

A question mark appeared above Chu Yingzong's head, and then it gave birth to more small question marks.

The world is confused.

--What's the meaning?What is Shi Xiaoliu asking?Does it have anything to do with them?He wants to keep a mistress?Or is he hinting at something?

Chu Yingzong:? ? ? ? ? ?

……

11:46 Beijing time, 23:46 New York time.

Richard Grinder, security director of Southern Cross Bank, was lying comfortably by the pool, holding a glass of lemon wine in one hand and resting his chin in the other.

- With all his own electronic devices gone, it was a perfect vacation with absolutely no one to bother them.

He looked at the wonderful body of his beloved mistress, Lilith, taking a dip in the pool.

The sound of rushing water sounded.

Lilith came ashore with a smile, the sight of the beauty out of the bath is really fascinating - he laughed.

She proudly kissed him on the cheekbone, then put on a bath towel and walked to the seat beside her.

Lilith picked up her champagne-colored phone and was about to take a selfie when she suddenly received an Internet call.

"Hello?" She answered the phone.

The voice of the man at the other end was a bit vague: "Hello, this is Nan'an Property Company. We are going to carry out a disinfection treatment on the whole community tomorrow morning. Is it convenient for the owner?"

Lilith said, "Ah, wait a minute."

She walked over, handed the phone to Grinder, and then leaned flatly and charmingly beside him, scratching his chest muscles with the wet ends of her hair.

Grinder was fascinated by her beauty, put one arm around her, and unconsciously answered the phone with the other.

He heard the man over there say, "Hello."

He subconsciously replied: "Hello, thisisRichard Grinder." (Hello, this is Richard Grinder.)

Click.

The phone was hung up abruptly, and no more words were spoken.

Two seconds later, Lilith was suddenly pushed away and fell off the beach chair, screaming.

However, Grinder wasn't in the mood to feel pity and pity at this time. Cold sweat broke out on his forehead, and he subconsciously took out his phone from his trouser pocket, only to remember that it was still lying at the bottom of the swimming pool.

Grinder stood up abruptly, regardless of his half-naked body, he ran out with all his might.

——Now he only regrets that he doesn't have electronic equipment, and he can't contact his deputy security director in time!

Grinder ran wildly, while yelling: "Security! Security! Contact my deputy supervisor immediately and tell him that my voiceprint has been leaked! My voiceprint!!—"

"Go and check our server immediately, hackers are attacking it!"
