Abstract
Disclosed is a file security method for reinforcing file security, which includes: by a first communication device, detecting an access to a file stored in a virtual drive; by the first communication device, requesting a decryption key of the file to a second communication device and receiving the decryption key; and by the first communication device, decrypting the access-detected file by using the decryption key.
Claims10
A file security method for a system in which a first communication device wirelessly communicates with a second communication device and allows a user of the second communication device to access a virtual drive on the first communication device when the second communication device is located within a predetermined distance from the first communication device, the method comprising:
- when it is determined that the second communication device is located within the predetermined threshold distance from the first communication device, processing, by the first communication device, to grant the user an access to the virtual drive on the first communication device,
- subsequently, when it is determined that the second communication device is located outside the predetermined threshold distance from the first communication device, processing, by the first communication device, to block the user from accessing to the virtual drive on the first communication device,
- wherein processing, by the first communication device, to grant the user an access comprises:
- receiving an instruction from the second communication device and activating the virtual drive according to the instruction;
- providing a list of files stored in the virtual drive to the second communication device for the user's selection of at least one file on the second communication device;
- in response to the user's selection of at least one file on the second communication device, sending a request to the second communication device for a decryption key of the at least one file;
- and
- in response to the decryption key from the second communication device, decrypting the at least one file and displaying data of the at least one file on the first communication device for the user to view the displayed data on the first communication device.
A communication device of a system in which the communication device wirelessly communicates with another communication device and allows a user of the communication device to access a virtual drive on the other communication device when the communication device is located within a predetermined distance from the other communication device, the communication device comprising:
- a storage configured to store a decryption key of a file stored in the virtual drive;
- and
- a drive control module configured:
- to determine whether the communication device is located within a predetermined threshold distance from the other communication device,
- when it is determined that the communication device is located within the predetermined distance from the other communication device, to send an instruction to the other communication device to activate the virtual drive on the other communication device,
- subsequent to activation of the virtual drive on the other communication device, to receive, from the other communication device, a list of files stored in the virtual drive and to present the list of files on the communication device for the user's selection, and
- subsequent to the user's selection of at least one file from the list, send a decryption key of the at least one file from the other device such that the other communication device decrypts the at least one file and displaying data of the at least one file on the first communication device for the user.
