Description

field of technique

The present invention refers to the IoT and the blockchain field and concerns a system which interfaces the Ethereum Blockchain level with the user, enabling its functionalities. prepared for the distribution, certification, archiving and verification of news.

Known art

The Blockchain? a revolutionary technology that has had a significant impact on commercial relationships, radically innovating the world of transactions.

In the last decade ? the epochal change has been highlighted, net of the aspects to improve that characterize the current phase of development.

? there is no doubt that this technology constitutes an innovative factor capable of affecting the existing political, economic and social structures.

In particular, after our country?s accession to the Blockchain Partnership, signed in Brussels on 27 September 2018, the Ministry of Economic Development, following a public call, launched the ?Group of high-level experts for the elaboration of the national strategy on technologies based on distributed ledgers and blockchain?, in the context of a multi-stakeholder process, aimed at implementing the development of innovative policies capable of promoting the development of Blockchain technology at a national level

The fixed points and the certainties of the use of this technology are the origin, the immutability, the consensus and the purposes. Well, ? an? opportunity? for many and not only for the world of commercial transactions: it allows you to range from the tracking of copyrights, to patents, to the multifaceted case history of the Internet of Things, to the Supply Chain, and thanks to this technology - the relationship from producer to consumer is strengthened - allowing, in particular, the defense of ?Made in?. The new frontiers also ensure innovative applications in the healthcare field or within the Public Administration. Think of the certifications, as in the case of identity cards, the land register, the vehicle register. It would also be an ideal choice for electronic medical records, which could initially concern a clinical center and then extend nationally or even internationally. Blockchains ? a type of distributed database which is used to replicate, share and synchronize distributed data across devices located in different geographical locations such as pi? sites, countries or organizations. The property? master of the Blockchain ? that there is no central administrator or centralized data storage mechanism.

Rather, it originated as a system not controlled by a single node or a group of nodes. Fundamental element to achieve this result? the so-called ?Consensus Algorithm?. It ? an alternative trust mechanism that replaces trust in a third party with trust in a decentralized protocol and algorithms.

Therefore, considering that you can not? be sure of the complete correctness and good faith of the applicants for entering data in a block, ? All information must be reviewed and confirmed before being accepted. This review and the criteria by which ? carried out ? the basis of the consent following verification of the correct construction of the block and of the transactions.

The transactions that make up the blockchain are grouped, in fact, in blocks and each block (except the first block) refers to or ? connected to a previous block in the chain. Computer nodes maintain the blockchain and cryptographically validate each new block and thus the transactions contained in the corresponding block.

There are several methods to reach consensus in the Blockchain: the two main algorithms are Proof of Work (PoW) and Proof of Stake (PoS).

The main feature of blockchain technology is, therefore, the possibility to distribute the network control of the devices, maintaining the objective tracking of all the transactions carried out through a verification protocol called ?proof-of-work? (POW): i.e. an economic measure to discourage attacks or other abuses of the service, by imposing some work on the service requester, usually understood as computer processing time.

On each node of the Blockchain P2P network? present the same distributed register that ? a database distributed in a replicated way, which archives, in a permanent and continuous way, a list of blocks. Each block contains information and points to the previous block in the list.

A peculiar connotation of these schemes? their asymmetry: the work must be moderately complex when building the block, but easy to control for the other nodes. This test? also known as ?CPU cost function?, ?client puzzle?, ?computational puzzle? or ?pricing function? of? unit? of processing that participates in the blockchain.

For example, the Blockchain technology underlying the BitcoinTM cryptocurrency uses a ?computational puzzle? called ?Hashcash? sent to all the nodes of the network, which all execute it in parallel with a considerable expenditure of energy, to then decide, on the basis of the first node solving the ?computational puzzle?, who is the node entitled to add a block to the network, guaranteeing its safety.

However, there are several less energy-consuming alternatives to the Bitcoin puzzle, such as for example the ?Challenge Response?, which provides for a direct link between the proposer and the provider of the computing service, or the ?Proof of Stake?, which bases the consensus distributed on parameters explicitly known to all members of the network, such as seniority? of service, committed amount and/or randomness.

Bench? the idea of applying the blockchain technology to contract the offer of services is not new, all the algorithms are then rendered in modality? centralized, through the activation of architectures of ?deep learning? on the cloud with the same needs? computations and big data access described above.

The use of Ethereum Blockchain technology? consists of a worldwide peer-to-peer server network in which ? managed a single distributed register on the basis of specific consent logics and capable of executing the so-called Smart Contracts (Computer Code written in a high-level and turing complete language). The latter give the Ethereum Blockchain the characteristics of a ?decentralized world computer?.

Ether, however, ? the cryptocurrency used in Ethereum which allows to reward the nodes, which deal with entering new operations in the distributed ledger in an organic, correct and consensus-based way.

Fundamental ? l?address in Ethereum, i.e. the address of a memory variable through which ? possible to make different types of transactions and to which ? associated with an amount in cryptocurrency that can be used to remunerate the Blockchain for the operations requested with the transaction itself. The address? usable only through the use of a private key uniquely associated with it.

Therefore, the Blockchain in its various implementations (Ethereum, Corda, Cardano, Algorand etc. ) makes available to the digital and therefore to companies, organizations, citizens and communities a series of advantageous and virtuous modules.

It?sa so-called exponential digital technology that will be? more and more functional to the evolution of ecosystems towards a sustainable, safe, circular and reliable social economy.

The relevance of this method highlights the nature of an instrument ?which can? democratize data and enhance trust and transparency?, as it ?reinforces citizens' autonomy? and improves ?transaction cost efficiency by eliminating intermediaries and intermediary costs, as well as increasing transaction transparency?.

Blockchain isn't it? yet simple and easy to use. There is a significant problem of skills and systems that are unable to operate and use the Blockchain.

The capacity? to be able to enter the information inside blocks with the possibility? to certify its origin and verify its content allows the use of this technology also in the context of the creation and dissemination of news, in order to stem the growing phenomenon of so-called ?Fake news?.

The definition FakeNews, false news or ?hoax?, indicates articles and news that contain invented, misleading or distorted information. The articles and news items are published with the deliberate intention of misinforming or spreading ?hoaxes? through traditional means of information or via the Internet, through social media (source Wikipedia) or other digital platforms.

AND? more easy to spread the fakeNews on online sources and social media where everything is more? liquid and less controllable. These sources represent more and more ?the?environment? where the news is born and read. Just think that in the age range? between 18 and 24 years, 70% of the news was read on the internet (Source ?REPORT NEWS SURVEY 2017?) Reuters.

In Italy, between 2019 and the beginning of 2020, AGCOM estimated that the percentage of fake news compared to the total number of online news produced, on average, was ? equal to 6.5%, with peaks reaching 7.9%

Fighting the phenomenon of online fakenews? become of fundamental importance for individuals and for democracies. The main problem ? that of? identification of paternity? and reliability? of the news and their traceability?, in this direction pu? the use of the blockchain is useful.

On the distributed register, in fact, each element ? characterized by traceability and immutability.

In this way it is therefore possible to identify the author of the news, verifying the content and also certifying its reliability, and allowing traceability? of the news itself.

None of the findings identified and analyzed to date involve the use of blockchain technology for the detection, creation, sharing, archiving and certification of news.

The purposes? aforementioned can be guaranteed through an interface through which to independently verify the origin and content of the original data through the use of cryptographic algorithms and blockchain.

Description of the invention

The present found ? an integrated solution to solve the above problems in a simple, transparent and reliable way.

The system object of the present invention, in truth?, offers the possibility? to create, distribute and certify the news in an integrated way, together with the identity? of the author and the time data of publication of the same.

Detailed description of the invention

This invention will come now illustrated purely by way of non-limiting or binding example, according to a preferred embodiment, with reference to the figures which illustrate some embodiments.

In the following description, for the purpose of explanation and not limitation, specific details are indicated, such as particular nodes, entities? functional, technical, protocols, etc.

In other cases, detailed descriptions of methods, devices, techniques, etc. are omitted.

A system and method is described that interfaces with blockchainethereum and communicates with the user for the implementation of various modules.

An intermediate layer is created between the users and the blockchain technology. According to one of the configurations, pu? also be interfaced with other IT platforms also already? operational.

The technological architecture of the platform will advantageously be modular.

According to one of the possible configurations, after having downloaded and installed the application, the User accesses by selecting the methods of use: as Author (Writer-Mode) or as Reader (Reader-Mode)(fig.1).

In the case of Writer Mode, the Onboarding function (authentication) is performed.

In the Reader module the user can instead activate only the verification function.

The Writer (Author) module, in its authentication function, has 3 phases (fig.2).

A first phase, Step 1, consists of the User entering his/her personal data via the interface, saving it and accepting the Privacy Conditions. In the second phase, Step 2, does the User create his own identity? digital on the Blockchain, the application requires the User to upload an identity document and generating a Private Key that the same uses as the Password for authentication and for enabling the certification of the single piece of news by means of the process which is the object of the present invention.

L?l?Identity? Digital Decentralized (DID) is generated by the protocol through certification through the use of the Digital Signature issued by an Authority Certified (Qualified Trust Service Provider ETSI EN 319 401).

The creation of an? identity? decentralized digital communication by a digital signature holder user allows, in fact, to create a two-way, strong, unassailable link between the user, digital signature holder, and identity? decentralized digital realizing, in practice, the?Identity? Certified Decentralized Digital (PID), and leveraging a legacy tool (digital signature).

Is then generated certificate of identity? digital in pdf format.

Personal data and documents are also archived in a certified, irrefutable and time-stamped manner on an integrated system consisting of the Blockchain and IPFS (InterPlanetary File System).

The integrated system stores all application data related to Identity

The third phase, Step 3, consists in the generation, by a specific Smart Contract, of a Unique Token identifying the Author (Author-Token) by automatically activating the newAuthors function of the Smart Contract by the Application.

In particular, according to this configuration, the Application sends a blockchain transaction executing the addNewAuthor function to the Smart contract.

By executing the function, a unique key/cryptographic token is generated by the smart contract that identifies the Author and a new record is created in the mapping authors Token creating a one-to-one link between identities digital author and author token.

According to one of the possible configurations, a cryptographic token associated with the user is released, generated using the SHA256 hashing function operated on a string of 10 random alphanumeric characters (alphabet of 36 characters) for a total of possible strings equal to 36 raised to 10.

In some examples, the token is associated with a graphic seal that identifies the author (fig.3).

At this point the? Author ? been entered in the Register of Authors, an archive present both in the application (Personal Data Author) and in the appropriate Smart Contract (Token-Author).

At the end of the issuance of this Token and the making available to the Author of the Token itself, the Onboarding Process ends.

The writer module, according to one of the configurations, can? also present the? Writing Area? function through which to generate and certify the article (fig.4).

The user can proceed with the drafting of an article/news using common editing and text drafting systems preferred by him.

For example, a PDF or Microsoft Word document? can? be loaded as content that will? widespread, once the content ? been created or uploaded to the publisher's computer system.

Through the ?Insert/Insert new article? function, the user can? insert the full text of your article in a special editing area using a drag-and-drop or copy and paste operation.

According to one embodiment, the application processes the text of the article entered in the editing area and extracts, through the SHA256 cryptographic algorithm, the Fingerprint and the loading timestamp.

In particular, according to this configuration, the Application sends a blockchain transaction executing the addNewArticle function to the Smart contract.

The Smart contract performs the newArticle function and, as a result, stores the Fingerprint in an internal archive (articles) and generates a Unique Token associated with the article (Article-Token) which identifies the article itself, thus creating a link one-to-one between the article and its Author.

The author, at this point, shares the News so? prepared on the media and certifies its News also on Blockchain by affixing its signature to this operation using the Private Key of its Identity.

Finally, in some examples, through a specific function, ? Is it possible to create, through a special graphical interface, a final certification seal that the author can? affix to the article before distributing it and sharing it on the various digital and social media outlets (fig.5).

The generation of the seal takes place via a private cryptographic key associated with the user and recourse to the identity digital. According to a possible configuration, the system pu? associate each news item generated with a status that identifies its Quality Class? of? article (eg. Platinum, Gold, Silver, Bronze, Garbage) and reputation of? author, providing a rating system according to the quality? and reliability? of the news.

According to an implementation of the present configuration ? Is it also possible to obtain a ranking system of the author linked to the quality? and reliability? of their articles.

The quality? of the news? verified directly by the smart contract by comparing its correspondence with the certified one present in the archive.

The rating of the author? calculated according to the following formula:

Where:

Q? the vector of qualities? of each article written by the author

K? the vector of punctual correction factors per item

N ? the total number of articles written by the author According to one of the possible configurations, this invention in the Reader module presents the article verification function.

The verification system is used, through an interface (for example, a web interface), to verify the author of the content and the content consumed by the end users.

This function can be used by all users regardless of authentication.

The Verification function allows a User to verify compliance? of an article you are reading. For compliance? of an article means l?identicit? of the content of the news you are reading with that certified by the Author.

According to one embodiment, through a script (javascript embedded in the graphic icon), contained in the seal, ? possible with a specific click on the latter (for example by means of a hypertext link), to receive on your application the text of the article to which this seal ? affixed, the author token and the associated article token (fig.6).

In particular, according to this configuration, the Application sends a blockchain transaction executing the checkConformity function to the Smart contract.

The Smart contract compares the fingerprint of the article received on the application following the click on the seal and the fingerprint that the author of the article had originally stored in the Smart contract/Blockchain.

The association of cryptographic keys allows the user who is reading a news with a special seal to verify that both the author and the content of the article are authentic (eg the content of the article has not been altered).

In particular, the verification process operates through the extraction of the full text of the article, of the Author Token and of the Article Token present on the Blockchain, and determination of the Fingerprint of the article on the device; a Blockchain transaction is then sent with which ? the checkConformity Function of the Smart Contract is activated and the determined fingerprint, timestamp and Article Token are transmitted.

Through the timestamp you can? also trace the exact moment in which the author of the content certified the latter on the Blockchain.

In particular, according to the present configuration, the Smart Contract through the article Token (sent by the Application via TX with author token and fingerprint) traces the Fingerprint of the original article and compares it with the Fingerprint of the full text acquired as described in the previous point (comparison algorithm).

In fact, has the system archived the binomial Hash (fingerprint) <->identity? in the Smart Contract? digital in a Table inside the Smart Contract and therefore not modifiable by external threats. This Table associates for each Hash (fingerprint) of original certified Digital Content the identity? digital that certified it.

According to an example application, at the outcome of the comparison made during the verification phase, based on the automatic and non-alterable result of the comparison, the Smart Contract returns the result to the application which can be positive or, in case of non-match, negative.

In the event of a positive outcome, the User will be sure that the text of? article ? actually compliant with what? that the Author had written and that he had registered on the Blockchain. If not, two functions will be activated automatically:

1) Alert for the User that he is reading a non-compliant article.

2) Will the Smart Contract provide? also to update the status of the article, downgrading it by one Quality Class.

According to this function, the Application sends a blockchain transaction for the execution of the setStatus function to the Smart contract which, based on gaming logics, will provide to decrease the score of? reliability? of the News (e.g. Platinum, Gold, Silver, Bronze, Garbage).

The one-to-one association given by the issuance of Author Tokens and Article Tokens, the comparison of cryptographic fingerprints and the consequent evaluation of the reputation and reliability ranking of the author and of the reliability and authenticity of the of the article? secured through the implementation of the following smart contract

contract SC_FakeAway {

mapping(address=>uint256) authorsTokens; //Table of Author Tokens

mapping(address=>uint256) articlesTokens; //Item Token Table

struct Article {

uint256 author;

//Returns the quality status? of a specified Item

}

//Check for compliance of an Article

}

}

From what is described in this paragraph it emerges how the module presents a correlation of different and integrated tools: IT tools, purposely created in an original way on the basis of this protocol, operational actions carried out in the said sequence by the users.

The terms used in the present application are used only to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as "comprises" or "have" are intended to designate the presence of features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, but one or more other characteristics. It is understood that the presence or addition of elements, numbers, phases, actions, components, parts or combinations thereof, does not preclude the possibility in advance. Terms such as first and second can be used to describe various items, but items should not be limited by terms.

Every time that ? described in this document that a given element ? present in "certain embodiments", "various embodiments", "certain embodiments", "certain exemplary embodiments", "an exemplary embodiment", or whenever any other similar language is used , it should be understood that the given element ? present in at least one embodiment, although not necessarily present in all embodiments. Consistent with the foregoing, whenever this document describes that a "pu?", "pu?" or "could" be performed, that a function, element or component "can?", "can?" or "could" be included in or ? applicable to a given context, that a given element "pu?", "pu?" or "may" possess a given attribute, or whenever a similar phrase including the term "pu?", "pu?" or "could"? used, it should be clear that the given action, feature, element, component, attribute, etc. ? present in at least one embodiment, although not necessarily present in all embodiments. The terms and phrases used in this document and their variations, unless expressly indicated otherwise, are to be interpreted as open rather than limiting. As examples of the above: "and/or" includes all combinations of one or more? of the associated listed items (e.g., a and/or b means a, b, or a and b); the singular forms "a", "an" and "the" should be read as meaning "at least one", "one or more?" or similar; the term ?example? ? used to give examples of the topic under discussion, not an exhaustive or limiting list thereof; and if an element ? described as "optional", that description should not be taken to imply that the other elements are also not optional.

While process steps, algorithms, or the like, including without limitation, may be described or claimed in a particular sequential order, such processes may be configured to operate in several orders. In other words, any sequence or order of steps that can being explicitly described or claimed in this document does not necessarily indicate a requirement that the steps be performed in that order; rather, the steps of the processes described here can be performed in any possible order. Also, some phases may execute simultaneously (or in parallel) despite being described or implied to be non-simultaneous (for example, because one phase is described after the other phase). Furthermore, the illustration of a process by its representation in a drawing does not imply that the illustrated process is exclusive of other variations and modifications to the same, it does not imply that the illustrated process or any of its steps are necessary, Although they have been shown and detailed various embodiments, the claims are not limited to any particular embodiment or example. None of the foregoing descriptions should be read as implying that any particular element, step, interval or function is essential. All structural and functional equivalents to the elements of the above-described embodiments that are known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be understood. Also, isn't it? It is necessary for a device or method to address every problem that the present invention seeks to solve, why? it can be understood from the invention. No embodiment, feature, element, component or step in this document ? intended to be dedicated to the public.

Likewise all modifications or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being within the scope of the present invention.

Advantages and features of the present invention and a method for obtaining them will become apparent with reference to embodiments described in detail together with the accompanying drawings and claims.

Therefore, it should be understood that the embodiments described above are illustrative and not limiting in all respects.
