Data security and data sharing product knowledge between organizations using blockchain technology.

. The digital world has developed very rapidly in the last 10 years. Data and information are everywhere and are already in digital form so that they can be accessed anytime and anywhere. Exchange of information, products, and knowledge also occurs between companies or organizations. This paper uses the Systematic Literature Review (SLR) application to determine the extent to which trends in the use of blockchain technology are applied, especially for data security such as data, information, and knowledge belonging to organizations—applying blockchain technology to share information with internal organizations or between organizations. Researchers found that data security with blockchain technology has been widely applied in various industries.


Introduction
The world has entered the era of the digital era where people in the world have developed in a new way where there is a worldwide connected internet network, digital devices, digital applications/platforms, and also social media, making it easier for people in the world to carry out all activities such as working and studying., carry out business activities and others.According to the World Bank, based on ITU (International Telecommunication Union) data, the portion of internet users in the world was around 49 percent of the population in 2017; the portion increased rapidly compared to two thousand, which was only around 6.7 percent.Similarly, Internet World Stats estimates that the share of internet users in the world will be 64.2 percent of the population in the first quarter of 2021.The estimated number of internet users is more than five billion, an increase of about 1,300 percent compared to two thousand.
Meanwhile, Indonesian internet users in the early 2000s were only around two million.They have experienced a significant increase in 2011, with the number of users up to forty-three million.Internet users in Indonesia in 2021 have increased, reaching 202.6 million.An increase of about 15.5 percent from the beginning of 2020.
Digitalization or digital transformation is a system update process in that companies follows Industry 4.0 rules.This process aims to increase user value and creation while at the same time providing more accessible and faster services for the company's internal parties, between companies, the government, and target consumers (B2B, B2C, and B2G).The positive impact of Digital Technology is to facilitate communication, facilitate literacy and make it easier to find information, such as making it easier to get certain services over long distances, for example, shopping online, ordering train tickets online, and others.In addition, it saves time and can be done anytime and anywhere-quickly finding.and getting information via internet access.However, there are also negative impacts.
The increase in the number of internet users in the world cannot be separated from the increasing number of threats or cyber-attacks.Especially for Indonesia, BSSN.(The National Cyber and Crypto Agency) informed that in 2018 there had been 12.8 million cyber-attacks.And then in 2019 there was a surge, namely to 98.2 million cyber-attacks, then in 2020 there were cyber-attacks with a total of 74.2 million attacks.(Project Report from Honeynet, BSSN).Any organization's data, information and knowledge must be stored in a manner sufficient to prevent theft or misuse by unauthorized persons.

Knowledge Management
The ability for knowledge management is very important in today's industrial world.The creation and diffusion of knowledge has become a very critical factor for enhancing competitiveness.Knowledge is now considered a very valuable intellectual asset.At the same time, knowledge assets are increasingly being valued as intellectual assets [1].However, so far it has also been supported by technology that is advancing very rapidly, especially digital technology in general.Industry 4.0 demands further attention to how knowledge is created by whom, for what purpose, and with what results [2].

Knowledge Sharing Using social media and Technology.
Organizations share product knowledge using tools such as Twitter, Instagram, YouTube, Facebook, and others.Defines social media "as a group of internetbased applications built on ideological foundations and web 2.0 technologies which enable the creation and exchange and sharing of User Generated Content [3].
The advancement of the Internet has shifted the focus of end users from passive consumers of web content to active user participation where they are given the opportunity to control, collaborate, create, communicate, and share content by using the web as a medium of communication [4].
As a typical form of presentation and application of technology implementation in Web 2.0, social media (mobile) relationships are made between various agents (individuals, groups, organizations, and existing institutions) with the help and support of technology and various Internet platforms (mobile) that have been growing rapidly to this day.As the Internet has developed into a more social and communicative place, more and more unwanted security issues (especially data security) and risks of privacy data theft have emerged.Concerns about ethical issues such as participant knowledge and consent, data privacy, security, confidentiality, data integrity, and the availability of various Internet platforms persist within the social media ecosystem.Given the emergence of issues of trust and risk in the digital world coupled with the increasing use of social media and the multiple identities, roles, groups, and associated behaviours, investigations of social security and vulnerability in men are more sophisticated and challenging than ever before.With the increasing use of mobile tools and applications over the past few years, it is important for every business organization to have best practice clear social media policies to maintain the security and security of credible and enduring social profile data [5].

Blockchain Technology
Blockchain is the latest advanced technology which exploits a decentralized network and can be used in various industrial sectors which is highly reliable, costeffective, and fast.Also available for financial services, retail, insurance, coordination, supply chain, and the public sector which is now starting to invest in Blockchain for their business growth.For example, the use of Blockchain to prevent double spending in financial transactions without the need for a trusted authority or central server.It is a decentralized ledger platform that intelligently facilitates verifiable transactions between parties both individuals and organizations.
Smart contracts and cryptocurrencies are the main applications of Blockchain.Smart contracts are selfexecuting contracts.Every transaction on the Blockchain is communicated securely using cryptographic mechanisms such as digital signatures, public and private keys, and hashing algorithms.Here, the privacy of the system is rendered tamper-proof, which makes it very difficult to make changes in the blockchain architecture.These transactions are immutable and highly secure blocks.Miners must perform intensive computations to complete the hash function in block transactions.Miners are rewarded in the form of digital currency for building successive blocks on the network.These blocks are added sequentially to the existing chain, and each user will receive the updated blocks using a peer-to-peer network.Enterprise blockchain requires consensus, source, immutability, and finality.properties in executing smart contracts between various parties in the business chain.As a result, companies can implement new business models with lower costs, time, and risk [6].
The National Défense Authorization Act of 2018, DoD will conduct a very comprehensive study of Blockchain, particularly in cybersecurity topics.There are DoD investments (i.e., research grants and SBIR/STTR awards) that investigate Blockchain for secure messaging in tactical scenarios, additive manufacturing, and supply chain security.On the other hand, there are concerns that malware or other prohibited content, once on the blockchain, will be very difficult to remove.In addition, there are also concerns about the threat to Blockchain by quantum computing [7].
Blockchain is a technology that can be used for storage systems or digital data banks related to cryptography.Its function is inseparable from Bitcoin and other Cryptocurrencies.Even so, there are so many other sectors that can take advantage of technological developments from this Blockchain.Blockchain technology has indirectly made all transaction processes easier where various transactions become more secure and transparent.So that it can minimize the misuse of data, such as corruption or bribery.In addition, we can also use Blockchain in fields other than finance.As a digital ledger that records various transactions, Blockchain has higher security.Everything that is logged cannot tamper with or retrospectively change, this is what makes Blockchain very secure.
With the high growth of medical device providers, many new medical device products are equipped with the latest technology.The purpose of this SLR research is to answer questions regarding the research question: 1) What has been the trend of implementing blockchain technology in data sharing and security over the last four years?2) What industries have implemented blockchain technology, especially for data sharing and security?3) How many publishers and researchers are researching the application of blockchain technology for data sharing and security?4) What types of blockchain technology are often used for data sharing and security?

RESEARCH METHOD
The methodology used to conduct this research is the Study Literature Review (SLR) which includes: several stages: selecting sources of information, determining search keywords and criteria for initiation of inclusion and

Selection of article databases
In terms of setting the number of articles, articles will be retrieved from a set of databases that have been selected.The databases selected for this project are international Scopus publications and Google Scholar.

Search Terms
The search keywords used in the list below are crucial to finding related articles in terms of answering the questions in this research.The search was conducted between January 2019 and June 2022 or 3 years back, and this article has a complete structure consisting of the journal/conference, author identity and other information.To narrow the search to be more specific, Boolean search strings have been used to create keywords to search for.Three keyword patterns (search in title words and keywords) used to answer the research question are: Title Words: Data Sharing, Keywords: Blockchain Title Words: Data Security, Keywords: Blockchain Title Words: Blockchain or Blockchain Technology

Selection of Papers: Inclusion and Exclusion Criteria
Articles found through searches that have been carried out, to be evaluated further to the next stage.Articles are only included in the literature review if they meet predetermined criteria and standards (see Table 1 below).This criterion aims to filter articles that are not related to the research objectives.Articles that do not meet the criteria are not examined further, while articles that pass the selection will take the full text and review it at the analysis stage.It is a requirement that the article has been peer-reviewed.

Data Analysis
Content analysis was chosen as the analytical method for conducting this research.This study aims to find trends in the application of blockchain technology in terms of implementation in terms of data sharing and data security.Moreover, it is assumed that most of the articles will not deal with easily comparable statistical data.Articles that have been selected through a selection process are translated and categorized into the following categories: Data Sharing, Data Security, and Blockchain.

DISCUSSIONS
This study analyses four hundred papers search results from the Title Paper: Data Sharing or Data Security with the keyword is Blockchain from Google Scholar and Scopus.After that, the next step is to eliminate duplication, where 133 duplicate papers were found, bringing the total paper to 267 papers; from 267 papers, seventy papers were selected that were related to the research question studied.

Trends in the last four years
The first research question, trends in the last four years, was related to the research question "What is the trend of implementing blockchain technology in data sharing and data security in the last four years?".Then from seventy papers, we can see the trend for the past four years (full year) in the table below.Seen in 2019 as eighteen papers and an increase in 2020 and 2021 as 19 and 21 and 2022 is 12 which means that the need for blockchain technology is indeed increasing.

Organization and Industry
The second is about how organizations were related to the research question, "What type of industries have implemented blockchain technology, especially for data sharing and data security?" in total, there are seventy organizations that use blockchain technology in terms of data sharing and data.
After we read more in-depth to see the application of Blockchain for data sharing and data security, here will calculate trends from papers that discuss data security and data sharing using Blockchain and will also explain what types of industries are implementing.
this, trend by year, group by publisher.After 70 papers were studied in more depth and can be seen that the industry trend in the application of blockchain technology for data sharing and data security can be seen as shown in the table below Here, it is seen that the application of blockchain technology for data sharing and data security has been widely used in various industries, from the summary of 21.43% for vehicles, 15.71% for Health Care, 14.29% for medical records, 10.00% for supply chain papers, 2.86% for energy trading, 2.86% for access control papers and others is 1.43%,A total of 29 types of industries that implement data sharing and security using blockchain technology.

Trend by Publisher
The third question is how many publishers publish papers on blockchain technology in terms of implementing data sharing and data security and was related to the research question "How many publishers and researchers are researching the application of blockchain technology for data sharing and data security?"After 70 papers studied in more depth, the publisher trend in the application of blockchain technology for data sharing and data security can see as shown in the table below.Judging from the table above, there are sixteen publishers for papers regarding the application of blockchain technology for data sharing and data security, of which the most are IEEE Explore with 60.00%, Elsevier with 8.57%, Springer with 7.14%, mdpi.com with 4.29% papers, hindawi.comwith 2.86%, Taylor and Francis 2.86% and others 1.43%.

Blockchain Technology Type
The last question is about Blockchain Technology Type and was related to the research question, "What types of blockchain technology are often used for data sharing and security?"After 70 papers studied in more depth, the type of blockchain technology often used for data sharing and data security can see as shown in the table below.

CONCLUSIONS
This systematic literature review at providing an overview of relevant studies regarding trends in the use of blockchain technology for the application of data sharing and data security from 267 selected papers, seventy papers discussing this matter or around 26.21%, and in the last four years (full year) also an average of twenty-two papers that discuss this matter.
There have also been many applications in the industrial world, from 70 papers grouped into 29 industries that have implemented this and the six major types of industries that use it are Vehicles, Health Care, Medical, Supply Chain, Energy Trading, and Access Control, and as well as in 3 years Lastly, there are 16 publishers who have published research on this topic as well and the types of application of blockchain technology have also many variations which are attached to table 6.0 above and from 70 papers conclude that the application of blockchain technology has worked well, according to user needs with good performance.

Limitation and Future Research
The limitation of this study is that only articles from the two databases that have been used.This means there is the potential that the results may vary if additional databases are included in the study.However, because the two databases selected were large and contained most of the published work in the research field, the potential for change was considered small.Future research is expected with more article databases; it is hoped to see if there are implementations of Banks, Education, Small and Medium Enterprise organizations, and Government institutions because there is also an organization that is important to maintain data security.Another issue can research how awareness, insight, and knowledge of the four industries, such as Banks, Education, and small and medium companies, about the need for their data security by using blockchain technology.
