Dark data refers to the vast amount of information that organizations collect, process, and store but do not actively use or analyze. This data is often hidden within databases, logs, emails, archives, and other digital storage systems. While it has the potential to provide valuable insights, dark data remains untapped, largely because organizations either overlook it, lack the tools to process it, or do not recognize its potential value.

Key characteristics of data data include:

1. Unstructured Nature: Dark data often exists in unstructured forms, such as text documents, images, and videos, making it challenging to analyze with traditional data processing tools.
2. Volume and Variety: The sheer amount and diversity of dark data can be overwhelming, as it encompasses everything from unused client interactions to forgotten log files.
3. Storage and Maintenance Costs: While dark data is not actively utilized, it still incurs costs for storage, security, and maintenance, potentially creating inefficiencies for organizations.
4. Potential Risks: If not managed properly, dark data can pose risks, such as exposure of sensitive information or regulatory non-compliance, especially if it includes personal or confidential data.
5. Untapped Value: Although it is unused, dark data may contain valuable insights that could drive business decisions, improve operations, or lead to innovations if properly analyzed.
