Blockchain Can Protect Your Personal Data In Contact Tracking Systems


In the fight against the Covid-19 pandemic, contact remains an effective weapon. His account involves many suspicions about security and privacy. DLT can help with these skills. Pandemic coviD-19 continues to be a serious threat to social and economic life. Although vaccinations have started in the population, far from social experience and limited access to abstinence, they remain the most expensive and practical among men.

In particular, instantaneous contacts seem to the best tool for breaking and taxing regulations in the context of barriers to work. The success of the system that you follow depends on the percentage of attacks that offset by them. The more people use the contact type system, the more likely it will to avoid their business. Resistances, however, pertain to security and privacy.

Contact Tracking App, Blockchain A Privacy Solution

However, the solutions proposed thus far have, in large part, due to inconsistency in acquiring, restoring, and vigilant the health of related relations, which could lead to excessive government surveillance. Public utility impedes the private life of the Blockchain. Indeed, the lack of existing contact systems today arises essentially from the lack of public security of their information and the risks that in the future this information could be used for diverse and unknown purposes.

In this regard Apple Inc. and Google Inc. They committed to developing technology to assist health authorities to monitor citizens through the kinship detection system. This solution involves various types of privacy and information security. The potential access to health information by these Big Players is another way of resisting citizens.

It is therefore clear that it is necessary to ensure the implementation of these instruments. It is necessary that citizens, through adoption tools, address their concerns so that they may enrolled in the confidentiality, integrity, and availability of personal information collected by many residents. At this time, there is a technology barrier that could provide practical and extensive access to the implementation of a contact system, while protecting personal information, privacy and interoperability security.

Blockchain Technology Is Applied To Contact Tracking


The model, which is a central obstacle to the system, allows the public to able to overcome and manage their private lives, helping to create a climate of trust and transparency essential to the success of accounts Blockchain. contact. to follow. Contact systems can provide on-road security solutions to the technological obstacle, including the fundamental features of decentralization, privacy and immutability.

It would be a decentralized contact tracking platform based on building technologies. Institutions, public and private, and citizens have able to share and verify their identity without revealing their identity. Let us think about the public substructure to which all public and private resources connected. With the patient’s consent, all cases of positive new care pertaining to the mentioned virus reviewed daily by various health care systems.

The test results were secured with the patient’s private identity and a registered public key. All citizens, therefore, must adhere to the context of the application, information exchange, and event-related registry, including the location of the user and their relationship to the subjects whose public key is connected. with a positive test. Under this situation, the system automatically sends a risky contact notification (thanks to smart contract implementation).

Such a system, backed by handicap technology, would, on the one hand, allow citizens to experience positive contact with their subjects, without which it may possible, whether for themselves, for others, or for their health. In each member they know the identity of the natural persons; on the other hand, it would allow local health units and local authorities to effectively advise on the spread of infection without the risk of duplication or inaccurate reported information.

Summary Of The Characteristics Of Blockchain Technology


We talking about a technical conclusion, one of the applications of DLT (Distributed Ledger Technology). DLT technologies supported by distributed system readers, which can read and changed by all participating networks, which called “nodes”. Each computer participates in a network that manages a distributed copy of the cursor specified in the “node”. In such a system context, any activity that a change in the archive is recognized, approved, and confirmed by various nodes.

The procedures for receiving consent and record structure applicable to various DLT technologies. The enclosure is, therefore, a distributed system (public or private) with the structure of a clause (hence the name ‘block’ and ‘chain’, which operate in an equal manner without authority and authority.

Encryption Protocols

Another fundamental notation barrier to the technology is the adoption of sophisticated encryption protocols, which ensure the anonymity of businesses in which they engaged. These protocols allow for a higher level of confidentiality of information. The UN governs the identities of subordinates through information systems and first-hand witness. This enables the programmer to demonstrate information without using the specified information.

This allows verification of communications between projects and businesses to kept private. In a technologically based technology, the data that involved is essentially two parts: the public key and the digit padding.

The public key, which always responds to only the user’s private keys, used in keys unless the user has at least one open key. Therefore, the public key can linked not only with the natural person, but also with an entity or object (for example a mortgage swab kit) to detect the production chain.

In the context of using RSA algorithm (a crypto-system based on public keys and private keys), although in some situations it can explore the identity of the user with the private key, these extraordinary circumstances that require an application. individual tools and resources (such as digital forensic and analytics tools). Therefore, the public key is only a fragment of information that shows the specific features of the user (for example Covid19 positivity) on a particular day without revealing the identity of that user.


There is no mathematical algorithm that allows you to transform a text of arbitrary length into a series of numbers and letters with a defined size, which is always the same. This feature allows you to print “type” or “composite” print, which is not enough information to convert to the original text as the output has a predefined length and therefore corresponds to a finite number. immense sums of money can exchanged. In accordance with what has stated in Part 136 under this unidirectional link, in no way to print, acquire originals in any way or acquire information, such personal information cannot viewed as personal information, but generally. anonymous information.


Therefore, even if no reliable technical information can obtained from anonymous technical difficulties, it may assumed that the use of such systems permits a higher level of use in any context of de-identification. and the other parts of the cloister and the third part.
