What Is Metadata ?

[0:00]One of the most important concepts of the digital world is data and data security. Now, the circulation within the business world, shares made through social media, personal data and more are housed in the digital world. Interviews with many digital communication tools, the daily flow of billions of data also pose some risks. Protecting these data both where they are stored and during transfer has become one of the most important topics of ensuring data security throughout the world. When we look at the overall structure, the data concept also has many lower and upper headings. The topic we will talk about today is the concept of metadata. Metadata, in other words, is data about data that defines a system source or elements of data. We can call metadata a kind of digital letter information. For example, we can say that all data except the subject line of emails, the length of conversations, the location information at the time of communication, who you are communicating with, in short, the messages or conversations, are covered by metadata. A little metadata can help you have very critical information about a person's life. For example, someone texted a guy an ecologist from 14:42 to 15:26 on Monday and then called the family planning center at 16:14. After an eight-minute voice call, he sent a message to a group of university students. There is a lot of metadata information in this sentence. Information about the day and time, who was contacted, how many minutes of calls were made, as well as detailed metadata information. One important issue that should be addressed here is the safety of metadata. Many social media platforms, social communication tools share information that conversations are encrypted from end to end. But here is the part about the content of the conversations that are encrypted. Therefore, metadata is in an open position to transportation. This, in turn, brings serious risks. Now, let's give another example to better understand metadata. Let's go. We have something with a doc extension. That's metadata. We can access information such as who created the doc extension data, which version was used when it was created, which template was used, who changed it last, what program it was written and on what date it was written. This, in turn, shows a weakness in the sense of cybersecurity. Another issue that we need to address here is that everything that is digital contains metadata. So, this topic is PDF only comma. It shows us that there is metadata in shares such as videos, images that are in a digital environment, not data such as DOC.
