Its game changing traceability and security features deserve thorough investigation to determine which privacy solutions can be developed.
With the emergence of artificial intelligence and the popularity of Internet of things (IOT), in some cases, customers may enter a repair shop with the shortest waiting time to repair the tire, and automatically go through the registration / checkout process.
This can be done with a smartphone or better, such as talking to a car.
The mechanics have already taken out the tires to be used and prepared them, and even prepared a cup of coffee – just the way customers like it.
This level of luxury concierge service may make automobile manufacturers stand out from the competition; However, personalized services like this need a lot of data, which naturally leads to privacy issues.
According to the IBM Institute of business value, if a car brand is more secure and private, 62% of consumers will give priority to the brand. In 2014, the alliance of automobile manufacturers recognized the need to solve the problem of privacy first, and issued the “principles of privacy protection for automobile technology and service consumers”（ Joanne Molinaro, left)
These principles require alliance members to abide by the following principles: (a) transparency（ b) Selection（ c) Respect the background（ d) Data minimization（ e) Data security（ f) Integrity and access（ g) Accountability.
Blockchain is a decentralized digital ledger used to record transaction information across multiple computers.
What is the role of blockchain in privacy discussion? Blockchain has been touted as a panacea to solve various problems of big data, including traceability, “hacking” and human error.
In many ways, blockchain functionality may also provide solutions to privacy issues.
Take the principle of “integrity and accessibility” adopted by the alliance as an example: “the participating members promise to take reasonable measures to maintain the accuracy of the covered information, and promise to provide reasonable means for ship owners and registered users to review and correct personal subscription information…”
The virtual invariance of the data stored on the blockchain can ensure that the data will not be modified or otherwise become inaccurate. Any “corrections” that need to be made will be accurately reflected as modifications to existing data that cannot be deleted.
As a matter of fact, data invariance is one of the many aspects of blockchain that can not be broken. It is also another principle of the alliance: “the participating members promise to implement reasonable measures to protect the covered information from unauthorized access or use.”
When the signs of blockchain technology and powerful encryption technology confuse (if necessary) the participants and the terms of the transaction, blockchain may provide the most powerful solution to solve the network security problems that continue to disrupt business operations.
However, it is the invariance of blockchain data that may cause problems.
Once written to the blockchain, the data will stay on the blockchain forever. One of the principles of the alliance’s statement is to ensure that its members retain “the information they cover for no longer than they need for legitimate business purposes.”.
The European general data protection regulations also require that personal data should not be kept longer than necessary for its processing purposes. How can blockchain be consistent with consumers’ right to delete data?
Data invariance is a function of decentralization. Therefore, in order to provide the “Delete button” on the blockchain data, the blockchain needs to reduce decentralization（ Jeff cable, left)
These blockchains are called “licensed” blockchains or “alliances”, in which the nodes are not anonymous, access to the blockchain needs the consent of other participants, and the data may be easier to change. However, as decentralization decreases, so will all its benefits, namely security.
Since there are fewer and fewer nodes responsible for maintaining data integrity and security, attacks on data will become more vulnerable. However, most people agree that the traceability and security features of blockchain changing the rules of the game deserve a thorough investigation to see what privacy solutions can be developed to solve this problem.
At the same time, of course, the most important feature of all privacy is still consent. We can all choose not to give up our data, even if it means that the next time we have a flat tire, we have to drink pure black coffee instead of morning lattes.
