Files will be downloaded only by determined users and all the users will be able to know, who has access the files and when and if the file has been changed.

Also, the files have to be encrypted.

The block needs the following data: file_id, date_modification, id_user, if the user has accessed the data or not, link to the file.

The languaje will be determined by the programer.
