Method, system, and storage medium to safeguard files from unauthorized copying

A system for preventing a file to be protected, from being copied, comprising:

• a host, installed with a prevention of replication application, for enabling or disabling a setting procedure, processing the file to be protected, and defining a supplementary protective zone after processing the file to be protected;
• and
• a storage medium, in a communication connection with the host, the storage medium having a firmware and at least one storage region, the firmware allowing the prevention of replication application to set the supplementary protective zone and a data blocking procedure, the at least one storage region for storing the file to be protected;
• wherein, the host notifies the firmware of the storage medium, of a predetermined logical block address corresponding to the supplementary protective zone by means of the communication connection, so as to complete the setting procedure for preventing the file to be protected, from being copied, and when a data access address read by the host from the storage medium comprises the predetermined logical block address, and the firmware executes the data blocking procedure that is pre-stored, so as to prevent the file to be protected, from being copied by the host.

A storage medium for preventing a file to be protected, from being copied, suitable to be in a communication connection with a host installed with a prevention of replication application;

• the host enabling or disabling a setting procedure by the prevention of replication application, processing the file to be protected, and defining a supplementary protective zone after processing the file to be protected;
• the storage medium comprising:
• firmware, for allowing the prevention of replication application to set the supplementary protective zone, and a data blocking procedure;
• and
• at least one storage region, electrically connected to the firmware, for storing the file to be protected;
• wherein, the anti-copy application of the host notifies the firmware, of a predetermined logical block address corresponding to the supplementary protective zone by means of the communication connection, so as to complete the setting procedure for preventing the file to be protected, from being copied;
• when a data access address read by the host from the storage medium comprises the predetermined logical block address, the firmware executes the data blocking procedure that is pre-stored, so as to prevent the file to be protected, from being copied by the host.
