In the vast digital universe we inhabit, every file we create, share or store carries with it an invisible but surprisingly revealing load of information. This data about data, known as metadata, is the backbone of digital information organisation and management.
With tools like Metashield, you can manage and protect this sensitive information hidden in your files.
What is metadata?
Imagine that every digital file is like a book: the content would be the text you read, while the metadata would be the cover page, table of contents and copyright information. This ‘data about data’ provides context and makes it easier to manage, search and understand digital information. Metadata is, in essence, structured information that describes, explains and locates information resources.
There are different types of metadata that serve specific functions. Descriptive metadata includes information such as file title, author, creation date and keywords. On the other hand, structural metadata describes how a digital resource is organised, while administrative metadata provides technical and management details, such as file format and copyright.
What information is contained in metadata
Depending on the type of files, metadata can include a wide range of information. For example, in the metadata of a digital photo you may find EXIF data that reveals the camera used, exposure settings and GPS coordinates.
For documents, the author, the date of modification or creation, and the number of revisions are often recorded. For audio files, ID3 tags provide details about the artist, album and genre.
What metadata is used for
Metadata has significant practical applications in a number of fields. In digital forensics, it is crucial for revealing valuable information about the creation, modification and transmission of files. They can help reconstruct events and establish timelines in criminal investigations.

They also play a vital role in digital rights management by protecting intellectual property through copyright and licensing details. On the other hand, descriptive metadata is essential to improve the visibility of web content in search results.
But it is not all advantages. It can also reveal sensitive personal information and become a potential source of security vulnerabilities if not properly managed.
How to remove metadata with Metashield
Plus, you don’t need complex installations to use it, just upload your files from anywhere to start managing your metadata. And if you are an advanced user, Metashield also offers an API that allows you to integrate its functionalities in other processes.
But let’s take an example. Imagine you are about to share an important document with a client. Before sending it, you upload it to Metashield and the tool reveals that the file contains metadata with revision history, internal comments and your location. With a few clicks, you can edit the metadata, remove this sensitive information with personal data and make sure you only share what you want to share.
The future of metadata and digital privacy
As the world becomes increasingly digitised, metadata is becoming more and more important. From the development of artificial intelligence that feeds on this data to improve its algorithms, to semantic systems that promise to revolutionise the way we organise information, it is clear that metadata will play a crucial role in the technological future.
In this context, tools such as Metashield become indispensable. They not only protect our privacy but also give us control over our digital footprint. As we move into an increasingly interconnected future, managing metadata properly will be an essential skill to navigate the digital seas safely.
Metashield is one of the many digital solutions we are developing at TU to face the future with the best tools. Visit our website and take a look at them all. We are absolutely sure you will find them very interesting.
