Information
The annual 315 party came as scheduled, exposing many industry shady scenes. Let the people once again see the ugly prototypes of these black industries. Among them, the probe box's ability to obtain personal privacy has aroused heated discussion. Today we will talk about what blockchain technology can do to protect our rights.
This year’s 315, the main exposed issues are: the black industry of medical waste, dangerous hot strips, "make-up" eggs, wicked intelligent harassment calls, how can qualification certificates be so attached, unhygienic hygiene products, after-sales service routines Duo Mingxiu can't hide from fraud, is electronic cigarette really healthy, bank card flash payment function saves the hidden dangers of theft, and shady online loans.
Behind these livelihood issues, it shows that the illegal activities of manufacturing and selling fake and shoddy goods are still not effectively contained, and personal privacy information can be easily leaked. Is there a solution to the blockchain?
Blockchain + medical waste treatment
In the exposed cases of the black medical waste industry chain, we have seen that dilapidated factories in Henan, Shandong, Shanxi and other places are filled with medical waste such as infusion bottles, infusion bags, and medical waste such as disposable syringes. The bosses of these factories process medical waste with drug residues into shredded materials without relevant qualifications. The shredded materials will be directly made into plastic mesh bags, vegetable nets, washbasins, plastic bags, foam floors, and other materials by downstream companies. Sex drinking cups, etc., and even children’s toys contain 70% to 80% of recycled materials.
Medical waste is a huge hazard. According to Wang Hui, Director of the Information Division of the Health and Family Planning Supervision Center of the National Health and Family Planning Commission, at the "2018 Medical Industry Blockchain Technology Application Forum", the medical waste cases handled by the health supervision department are about 20,000 per year. Cases, accounting for more than 70% of the total number of infectious disease prevention and control supervision cases.
The treatment of medical waste has multiple links (including department classification, packing, temporary storage, in-hospital transfer, centralized storage, out-of-hospital transfer, terminal disposal), and multi-party coordination (the personnel involved include: ward nurses, nursing workers, and hospital temporary storage personnel , Transportation personnel, destruction point personnel), very suitable for the application scenario of multi-role subject such as blockchain.
At present, the health supervision department has designed a "medical waste supervision system" for multiple links and multiple roles. The bottom layer of this system adopts the public chain of DPoS+PBFT consensus mechanism, which has strong fault tolerance and stable consensus. The key node data of the medical waste treatment process is uploaded to the blockchain for storage. The data uploading process adopts local real-time uploading. At the same time, the uploader, uploading time, uploading place (data such as GPS or mobile base station) are attached to ensure the operation of the chain itself. Truth believable.
Uploading regulatory information from the source of the information on the chain can maximize the objectivity and authenticity of the information. On-chain supervision makes full use of the distributed and non-tamperable ledgers of the blockchain, and solves the problems of information asymmetry and trust among multiple participants, making supervision more evidence-based and processing more targeted.
Blockchain + food safety
"It's delicious, refreshing, a little sweet, a little spicy, and chewy." When the primary school student was asked why he likes spicy sticks, he gave this answer.
However, the secret behind the fragrant taste and stimulating taste of spicy noodles is the spicy eyes: the food production workshop can be entered without any disinfection measures, and the puffed noodle balls on the production line splash around on the floor of the production workshop. The dust on the floor is intertwined with the oil oozing out of the machine. The mixing barrel is also full of oil, and there is a pool of water a few meters away from the mixer. There are black stains everywhere on the wall of the pool. The white bucket and the side of the bucket in the pool are covered with thick dirt. A drop of water is constantly seeping from the rusty interface of the faucet and falling into the bucket below.
As the host said: Food is divided into staple food and snacks, but food safety is absolutely not a priority. In terms of ensuring food safety, in addition to the need for relevant departments to continuously increase supervision, the introduction of new technologies is also very important.
Blockchain traceability is an important technical means to solve food safety. In recent years, the scale of applications has also been expanding. From the early IBM to the later JD, Ant Financial, ZhongAn Technology, etc., there are cases in this respect. .
For example, the fresh food traceability system previously cooperated by Tsinghua University and Yonghui Supermarket starts with fresh food breeding, processing, storage, distribution, and receipt, and uses blockchain technology to improve food safety. ZhongAn Technology’s step by step chicken project, an anti-counterfeiting traceability solution based on blockchain + Internet of Things, can ensure that all the data generated by each chicken from the chicken to the chicken, from the chicken farm to the table, is true Record, truly realize the anti-counterfeiting traceability of each chicken. Ant Financial's blockchain traceability helps authentic honey out of the mountains.
However, the time stamp capital Zhang Yuxin stated that blockchain traceability technology cannot prevent the production of counterfeit and shoddy goods, and the authenticity of on-chain data cannot be identified unless there are additional offline linkage measures. The most reasonable scenario of traceability technology still needs to go to the source, upstream of the industrial chain. The more upstream the contact, the more difficult it is for fraud.
Fan Jingang, general manager of China Food Chain, believes that technology alone cannot solve fraud. First of all, anti-counterfeiting technology must be used to maintain authenticity and reduce human intervention. Then put these anti-counterfeiting and fidelity information on the chain to ensure consistency between the chain and the chain, and the information traceable to the blockchain can be truly and accurately transmitted to each link of the industrial chain.
Usually, the objects of blockchain traceability are high-value commodities. Is it worth using the blockchain for the five-cents per bag of spicy strips?
In this regard, Zhang Yuxin believes that what is worthwhile is that food is directly related to human health, and of course there is a need for traceability. What's not worthwhile is that spicy strips are not rice after all, and there are many alternatives. Small-brand spicy strips factories don't have extra money to buy a blockchain BaaS system to trace the source.
Blockchain + data privacy protection
In a sales office, a salesperson can directly make harassing calls to unknown mobile phone users near the store with a simple operation on the mobile phone with a probe box.
What is even more amazing is that with such a device, you can further obtain various private data of the user, including gender, age, occupation, income, mobile phone equipment used, what keywords have been searched online, what apps are commonly used, and whether Children, education level, etc.
The secret lies in: ①When the user’s mobile phone turns on the WiFi function, it will send a signal to the surroundings to find the wireless LAN. After the probe box finds this signal, it will further obtain the user’s MAC address and convert it into a mobile phone number. ②The mobile phone number is matched with the big data in the background of the system to obtain the user's private information. These private information mainly come from various APP software installed on the user's mobile phone. When the user installs the APP, he is required to open various permissions. The user's mobile phone imei, MAC address, mobile phone number and other information will be sent to the APP back-end server. If the APP server sells these data to other institutions, the user's information will naturally It leaked.
Facing criminals using high-tech methods to collect personal privacy data, attorney Qiu Baochang of the lawyers of the China Consumer Association said that in the era of digital economy, businesses can collect personal information without users knowing it, and some of this information is not. The anonymization process is used for commercial purposes. The protection of personal information is particularly important, and it is necessary to use updated means to strengthen the protection of personal information.
Huang Minqiang, the founder of Gongxinbao, believes that the protection of personal information privacy can be achieved with the help of blockchain: "Under the centralized method, the storage, exchange and calculation of user data are solved in a centralized platform, and the platform can get it. The user data is sold, and the data may flow into the black market. Using a decentralized method, the data can be stored on the chain under the premise that the user authorizes the data, and the user decides whether to give the data to the application side. And the dataWhen authorized to the application side, it is used, exchanged, and calculated in a trusted environment (such as a scheme using cryptography, MPC, homomorphic encryption or TEE). "
You can also isolate the information from the outside world through privacy encryption technology, and only you and the person who has the relevant view key can decrypt the information. However, the most important thing is to popularize relevant knowledge to users.
