Reborn Tech Maniac

Chapter 355 Started to take on big projects
Tang Huan was a little embarrassed by what he said, so he stood up quickly and planned to leave.

"Your proposal to build China's Silicon Valley is very good. I will urge the relevant departments to conduct research as soon as possible."

"When I came back this time, I also brought some original English materials related to the industry, which can be regarded as first-hand information, and should be of some reference value." Tang Huan added before leaving the house.

It was indeed getting late, and Tang Huan was a little hungry. After eating a few pieces of pastries, he asked the waiter to bring him another bag, and threaded his fingers through the hemp rope on it with a characteristic of the times.

After getting into the car, Tang Huan thought for a while, then went straight to Zhao Yazhi's residence.

"Why are you here?" Zhao Yazhi, who was attracted to open the door by the knock, asked in surprise.

"I'm worried that you're not used to it, so let's take a look." Tang Huan put down the bag of pastries and took off his cold coat.

"I'm not that squeamish. I've already discussed it with the team. Tomorrow they will start discussing sportswear sponsorship. I just happened to visit the historic sites here. I think I will be able to return to Xiangjiang years ago."

It can be seen that Zhao Yazhi is very interested in this trip to Yanjing, and the ideal of traveling hidden in his heart has been indulged by Tang Huan to become stronger and stronger.

"Since the arrangements are made, then you can do your own work. I have various entertainments, so I can come over to take care of you at night." Tang Huan smiled and poured half of the enamel jar of boiling water.

"No one is right." Zhao Yazhi scolded, picked up a piece of pastry from the pastry bag she untied, and stuffed it into Tang Huan's mouth.

"You want to murder your husband." Tang Huan complained vaguely while chewing.

"Hurry up and drink some water." Zhao Yazhi picked up the enamel jar with a smile, blew on it gently, and brought it in front of Tang Huan.

Tang Huan gave up contentedly when most of the pastries were eaten.

"It's so late, and you still eat so much, you're not afraid of gaining weight." Zhao Yazhi joked after putting away the enamel jar and the remaining pastries.

"I can't help it, life is hard, I'm busy day and night, if I don't eat more, I'll have the strength to work later." Tang Huan chuckled.

……

The next day, Tang Huan and his uncle Han Anyuan met and went to Baiyi Road, which was the construction site that developed into Zhongguancun Street after a few years in the original time and space.

When I came last time, it was still under construction, but it is winter in the north, and outdoor work has long since stopped.

It is for this reason that the construction period is slower than the construction of Treasure Hospital in San Francisco.

In addition to the first $2000 million in funding, Tang Huan has successively added some additional funds.

Of course, the relevant departments in Hai_dian have made adjustments in land planning. The hotel and office buildings that were originally planned have become a small technology incubation area.

That is to say, because Yanjing has not developed yet, Tang Huan got the core land of Zhongguancun for nothing.

The person in charge of the construction unit pointed to a 12-story office building in the north and introduced, "This place should be ready for use around the National Day this year."

After Tang Huan asked his subordinates to take a few photos, he smiled at his uncle Han Anyuan, "When chatting with people from the scientific research institutions under the Chinese Academy of Sciences, you can use it as an attractive condition."

At noon, Tang Huan naturally wanted to sit down with the contractor and the officials of Hai_dian to eat, brag, and make friends.

Uncle Meng Qingguan also came over to join the dinner, and said something that made Tang Huan feel a little nervous.

China's Yinhe No. [-] was developed under the leadership of the National Defense Science and Technology University, and the official color is very strong; Tang Huan's research and development route for his Fangyuan supercomputer is a private cooperation, which will be built by several private technology companies. Finish.

The reason why it was so troublesome, instead of simply bringing in a complete system, was because Tang Huan wanted to leave a way out for himself, and also wanted to use this process to bring in a group of talents.

This model has been implemented very well in Singapore, so Tang Huan is very confident that he will succeed in one fell swoop. According to the plan, the final results should be produced before this year's National Day.

But it is precisely because of such a clear roadmap that everyone has disputes about where to put the supercomputer.

China's National Supercomputing Center was not built until the 21st century in the original time and space. Naturally, this concept has not yet emerged.

Therefore, all parties involved in the cooperation feel that they have the reason and ability to arrange a proper place to take care of the supercomputer.

In essence, these private technology companies are backed by top domestic universities, scientific research institutes and other institutions, which can be said to be in deep water.

Therefore, when Tang Huan heard Meng Qingguan say that the parties in the dispute wanted to find himself to be the referee, he repeatedly waved his hands, "I'm just a businessman who buys products. I don't want to get involved in such offending things."

"It's good that you understand the twists and turns. Anyway, through this series of cooperation, you have established a good relationship with various units, so there is no need to wade into this muddy water."

……

In fact, through the trust he gained from operating in mainland China, Tang Huan has already begun to get in touch with official projects with large profit potential, such as the third census that will officially start on July [-] this year, and the ongoing research and discussion For the resident ID card project, his company has to provide supporting hardware and software systems.

Since the founding of the People's Republic of China, two censuses were held in 1953 and 1964 respectively. Eighteen years have passed since today. China's population has grown from nearly 18 million in the last census to more than one billion now.

Therefore, high-level decision-makers are eager to know what indicators such as gender composition, age composition, ethnic composition, education level, urban-rural distribution, etc. have changed in such a large population.

Different from previous statistical methods, the computer was listed as a trustworthy tool for the first time, and Tang Huan naturally participated at the right time, and the analysis and processing of data are the strengths of his products.

Listening to Ni Guangnan's report on these tasks, Tang Huan was very satisfied, and then commented with some satisfaction, "Our Chinese card technology is becoming more and more mature and perfect. Even if the company has the opportunity to compete, but with this advantage alone, we will crush them."

Ni Guangnan nodded in agreement, and then handed over a notebook, "I recorded some categories of information collected by resident ID cards. The storage space required for 10 billion people is quite impressive when you think about it."

Looking from data items such as name, gender, ethnicity, date of birth, and address to the last 15-digit citizen ID number, Tang Huan couldn't help raising his brows, remembering that in the original time and space, it was impossible to report the loss of the ID card Bad experience.

Seeing that Tang Huan was looking at it seriously, Ni Guangnan continued to add, "We are still discussing whether there should be 'marital status' and 'occupation' on the resident ID card. If there is, the amount of data collected will be even greater."

"The amount of data collected, after corresponding to the inside of the computer, the technical difficulty may not be very high. As for the cost factor, such a major project, it must not be too sensitive." Tang Huan said lightly.

Although tape storage systems still have the advantages of being cheap and reliable, there is no doubt that hard disk storage systems are becoming more and more popular and becoming mainstream.

Cheap products like personal computers have begun to use hard drives, which is a good proof.

For example, the Seagate hard drive carried by the second-generation Fangyuan computer has a size of 5.25 inches and a capacity of 10MB.

In the field of enterprise applications, the 1973-inch hard drive 8FD launched by IBM in 33 occupies an absolute proportion.

In addition, Japanese manufacturers are also catching up in this field. In 1981, Fujitsu manufactured a 446-inch hard drive with a capacity of 10.5MB.

Tang Huan's killer product Fangyuan network server NS-4800 series, which focuses on the financial application field, uses this kind of storage system with a capacity of hundreds of megabytes.

Moreover, with the explosive development of the computer industry, the capacity and cost of storage systems are also rapidly developing in a direction that is beneficial to consumers.

Therefore, Tang Huan was not too worried about the amount of data contained in the project that Ni Guangnan was talking about, but asked another question.

"One of the keys to informatization processing is to uniquely identify objects. Judging from your notes, the information collection scheme for resident ID cards seems to be somewhat deficient in this most basic link."

"No way." Regarding Tang Huan's views, Ni Guangnan was a little disbelieving, "By assigning each person a 15-digit citizenship number, the unique correspondence of the witness card has been achieved, of which the first six represent the number of the household registration area, the middle six The first digit represents the date of birth, and the last three digits represent the sequence number, the male is an odd number, and the female is an even number, I feel that the design is very perfect."

Tang Huan smiled noncommittally, "Let's first confirm one issue, the role of the resident ID card, and what will be the development trend in the future."

After pondering for a while, Ni Guangnan replied firmly, "With the advancement of reform and opening up, the flow of people will definitely become more and more frequent. Compared with the trouble of household registration and introduction letters, the superiority of the resident ID card is irreplaceable. For purposes such as opening a bank account, the resident ID card is bound to be a necessary application condition.”

"That is to say, the role of the resident ID card will only become more and more important." Tang Huan snapped his fingers, "That's the problem, the resident ID card is used more and more frequently, what if it is lost? manage?"

"It's very simple, let's make a replacement." Ni Guangnan replied blurted out.

Tang Huan shook his head with a smile, "Then what if someone finds this resident ID card and uses it in a bank?"

"There are photos on it, and the salesperson of the bank must be responsible for checking the identity card." Ni Guangnan said it as a matter of course.

"Not to mention the quality that can be achieved in photo shooting and the possibility of batch agency business, can you guarantee that this will not happen in reality?"

Tang Huan shook his head disapprovingly, "The data collection plan for this resident ID card only focuses on management factors, but ignores the necessary safety factors, and the answers you gave are all placed in the most ideal situation. The results obtained from the next analysis will inevitably differ greatly from the actual situation.”

Speaking of this, Tang Huan pointed to the 15-digit citizenship number on the notebook and said: "The design of this code also has a big problem. The information it represents is too obvious and orderly. I don't deny that such a design, It will bring great convenience to the actual work, especially the front-line work. But precisely because of this, people with a heart can easily fabricate it. Find a real area number, fabricate a reasonable date of birth, Add a random sequence number and connect the three to get a legal resident ID number, even though it does not exist in the database, it is extremely confusing."

As the debate progressed layer by layer, Ni Guangnan's attitude changed from being confident and righteous at the beginning to being dejected and at a loss for words.

"We are considering the best case in theory, and you are considering the worst case in theory." Ni Guangnan smiled wryly, "But this set of resident ID numbers has already achieved the unique correspondence between people and documents. As for security Perhaps using fingerprints to achieve the unique purpose can be solved, but the problem is that it is not realistic to implement.”

"With a computer, fingerprints can also be stolen in the future. What should I do at that time, cut off the finger and change it?" Tang Huan shook his head dumbfounded, "Your solution is to set a password."

In the original time and space, after the second-generation resident ID card project, which cost a lot of money, was exposed with congenital defects that cannot be reported as lost, it seems that relevant parties are also using fingerprints to make a point.

Now that he has come to this time and space, Tang Huan is too lazy to complain, but he feels that since the company under his name has participated in this project, it is better to think about it in advance and resolve it invisible.

At this time, Ni Guangnan could also see that Tang Huan had his own ideas, but he couldn't get too involved in these domestic matters.

"What do you think is the best way to avoid this security flaw?" Ni Guangnan began to learn from the experience with an open mind, "I can compile a report and report it to relevant parties."

"In my opinion, the solution is very simple. You only focus on the uniqueness of the person and the certificate, but you ignore the uniqueness of the certificate itself. Then just do it from the most basic place, and assign a unique certificate to the certificate." A serial number, such as a combination of eight digits and letters."
