The dark data definition, as per Gartner Inc, is the information that is gathered, analysed, and stored during routine company operations but is not used. Dark data make up a significant component of the vast and complicated realm of big data.

Given that businesses often acquire, tag, bookmark, and retain data to gain insights, a sizable amount of it ends up as dark data. Because these data are left unused, over time, they start to lose their freshness.

What is Dark Data?

Dark data is processed data that businesses gather and keep but do not use for operational purposes. According to consulting and market research firm Gartner Inc., 'dark data comprises information assets that an organisation collects, processes, and keeps. This data is stored in the context of the company's ordinary business activities but often fails to employ it for other purposes.'

According to a research study conducted by IBM, nearly 90% of data collected by companies is left unused. It is very typical of most companies to analyse data that is used for transactional purposes. The remaining data are left untouched or minimally used. The data stored in these corporates are managed and maintained at a significantly high expense.

Dark data might include a variety of insights, like which marketing materials a particular customer responded to, how they responded to a survey, or how they reviewed a business or product on social media. Dark data may also contain past purchases from clients, the frequency of website visits, the geographic distribution of clients, etc.

Uses of Dark Data

A company will frequently hide data for practical reasons. By the time the data can be cleaned, it may already be too old to be relevant or useful. In this situation, records might be interpreted erroneously, supposed incomplete or outdated, stored on antiquated hardware, or include missing or outdated data.

Dark data is becoming more frequently linked to operational and big data. Examples include customer call detail records that contain unstructured consumer sentiment data, server log files that could show website visitor activity, and mobile geolocation data that might reveal traffic patterns.

This kind of dark data may be leveraged to generate new revenue streams, get rid of waste, and cut expenses. Therefore, cloud computing is being used by many businesses with dark data for regulatory requirements, detecting interesting dark data points, and connecting them to potential business uses.

Identifying Your Dark Data

It is important to reduce the load of dark data that is being stored in your system. You can identify your dark data by following these steps:

Outdated data: Data that has not been updated for a while is probably starting to become outdated. You can either update these data or simply remove them.
Least popular data: A low approval rating suggests that the information source is not well-known or dependable. Determining which pipelines, tools, and applications are providing the most output is the best practice for you.
Missing data source: An asset is no longer of any use when there are no data pipelines reading from or writing to it. You must analyse if any downstream or upstream application is still using that data.
Poor quality data: Poor quality datasets, such as empty or duplicate entries, erroneous patterns, and incomplete data, will produce insights that are insufficient or inaccurate. You can either update these data or can remove them.
Unwanted data: There are many tools to find data copies that are no longer needed, but are taking up space. You can use these tools to remove these unwanted data.
Unclassified or untagged data: Analyse your unclassified and untagged data to see whether they contain any sensitive information. Data breaches may be caused by missing data policies or by failing to identify sensitive data.

How to Manage Dark Data?

While businesses must and will continue to actively gather data, it is crucial to not disregard the free information that is already out there! It is obvious that to get intriguing and unexpected outcomes, it is necessary to be more inventive by posing fresh questions about the same old facts.

The present open scientific movement has sparked a nearly constant creation of cutting-edge projects and technologies that make up the open research infrastructure of today. There are many solutions available for the management of dark data. Some of them are as follows:

Artificial intelligence (AI) and machine learning are two examples of technologies that can assist firms in finding, managing, safeguarding, and gaining a complete view of their dark data. Additionally, firms that manage data can benefit from AI and machine learning to identify compliance and security concerns resulting from their dark data assets and take action to address any exposure.
By revealing the places and origins of stored data, data mapping can enhance this strategy. Data reduction can also be beneficial since it can reduce the amount of information that is kept and ensure that any information that is kept is suitable for the purpose for which it was acquired.

How to Implement Dark Data Management?

1. Establish the importance of dark data for your company

You must first explain why dark data is important to your company. In other words, what specific advantages do you aim to achieve by managing your dark data?

Reducing storage costs can be the solution for certain companies. Others can define it as increasing performance or discovering new information in their data. Before you begin, it is critical to have a clear understanding of why you're creating a dark data management plan.

2. Discover your dark data

You may locate and organise your dark data using data discovery tools, which will make the process simpler. You can rapidly determine which data is used and which data is dark with the use of these tools.

You should keep track of any data that might be governed by laws or regulations Other sorts of dark data cannot be managed in the same way as regulated data.

3. Create a retention strategy

The next step after identifying your dark data is to create a retention policy. How long you store your dark data and when you remove it, will be governed by this policy.

When creating your retention policy, keep the following things in mind:

The value of data: Different dark data types may have varying degrees of value. You should take the worth of the data into account when establishing a retention policy.
Data sensitivity: Dark data could occasionally include private information. Other sorts of dark data cannot be managed in the same way as this data.
Storage costs: Dark data storage may be expensive. The cost of retaining the data should be taken into account when establishing a retention policy.
Legal prerequisites: Dark data may occasionally be subject to legal regulations. Other sorts of dark data cannot be managed in the same way as this data.
Create a data management strategy: Creating a data management strategy that outlines each phase is the last stage for your dark data management. This plan will outline not only your dark data but your overall data management strategy

You can think of the data management strategy as a road map for handling your dark data. It should outline every action you are going to take for handling your data, from gathering it to deleting it.

You should keep in mind that the data management strategies should always be customised to meet the unique needs of your company. Dark data management is not a problem with a universal answer. Each company will have its bunch of data management strategies that may or may not work for your company.
