## 3 Data and Information  
In this section, a study by [PERSON] [7] discussed data confidentiality, looking at analysis of how data are managed and how users intended to protect the data. It is said that a tremendous amount of data about individuals including their demographic information, internet activity, energy usage, communication patterns, and social interactions was constantly being collected by national statistical agencies, survey organizations, medical centres, and social networking companies [7]. The approaches discussed here argued that users had a problem when it came to ensuring the link between the privacy of the data against any relational data that a company privately or publicly held. For example, the use of social networks and how a large number of people were linked together through various social media platforms such as Facebook and Instagram. Through means of social media, it allows malicious actors to trawl public information, and gain information readily across the internet. In this way, data can be easily leaked out through individual people within the social media network. Malicious actors also choose to link people and information and obtain data over time [7]. Users are not aware of how the data are being distributed and used, and consequently also not aware of what information is made public or not. Users of social media tend to want to share topics and pictures freely, and easily thus forgetting the privacy issues that arise around this sharing. These users forget to look at their own privacy settings and fail to update them from time to time. In data management, it is always useful to be aware of personal information and public personal information (PPI), and how social media and the internet translates to this. In a study by [PERSON], [PERSON] et al. (2020), a different notion to the above was researched on user awareness and consciousness of personal information on social media and how these participants were aware of the scope of public personal information (PPI) [8]. The [PERSON] study suggested that there was a concern for these social media users over the potential misuse of their personal information and data, which is closely related to individual privacy. Further, [PERSON] adds to the policy perspective of the UK General Data Protection Regulation (GDPR) which defines personal data as any information relating to an identified or identifiable natural. Data of this nature need management. According to [PERSON] [3], data management:  
\"...consists of the practices, architectural techniques, and tools for achieving consistent access to and delivery of data across the spectrum of data subject areas and data structure types in the enterprise, to meet the data consumption requirements of all applications and business processes.\"  
Technologists and inventors build tools to help society manage data and share data that are input into the internet. With the help of technology giants such as Microsoft, Apple, IBM and Cisco to name a few, there is a choice of tools and environments to make day-to-day management of data, easy and manageable. Through this infrastructure, these tools with the right software and devices around it, allow various levels of access and protection depending on the nature of the data being managed. The awareness of users utilising these devices is equally important in this management of data. The more connected to the internet society becomes, the more \"back doors\" are potentially opened. Malicious actors will always find a way to gain access to data they can sell on. This can leave data vulnerable in terms of others getting hold of it and how the malicious actors can take it. In practice, it is not possible to build a completely secure system. [PERSON] [9] explains that the internet is changing methods of computing rapidly,and possibilities and opportunities for malicious intrusions are very high and can cause high risk.
