NSA and CIA 'Kill People Based on Metadata' of Files, How to Self-Defense?
In general, there is 'data attached to data (metadata)' in the data that is overflowing with the world, such as the shooting date and shooting equipment for photos, and the creator and organization name for documents. Darknetlive, who writes articles about the dark web, introduces how to manage such metadata well and prevent exposure of personal information as much as possible.

In 2014, at a symposium at Johns Hopkins University, Dr. David Cole, professor of constitutional law at Georgetown University, and Michael Hayden, former director of the National Security Agency (NSA) and Central Intelligence Agency (CIA), said, ' We discussed the appropriate balance between individual privacy and national security.

Among them, Dr. Cole said, ``You can know everything about the owner with just metadata,'' and Mr. Hayden agreed with this, saying, ``That explanation is absolutely correct.We kill people based on metadata. That's it,' he said. As this statement shows, it can be said that metadata contains a lot of personal privacy information, so much that a person who is good at collecting information can control the owner's life and death.
Darknetlive says, ``I don't think there is a way to completely bypass the data collection technology of big agencies like intelligence agencies, but there are some valuable tools that can handle metadata at a rudimentary level.'' and introduced a tool for managing metadata.
