Abstract
Systems, devices, and/or computer-implemented methods for secure offline data storage are provided herein. More particularly, a system is provided that permits access to a data storage device when offline from various components of the system. Furthermore, the disclosed system may permit the re-setting of authentication passwords/PINs for the data storage devices, even when such data storage devices are offline from other components of the system.
Claims9
A data storage device comprising:
- a secure memory configured to securely store data, wherein said data storage device is a portable data storage device, and wherein said secure memory of said portable data storage device comprises a flash drive or a hard drive;
- a keyboard configured to receive password inputs from a user;
- a processor;
- and
- a communications port configured to connect said data storage device with a host device,
- wherein said data storage device is configured to connect with a remote device over a communications network,
- wherein said data storage device is configured to selectively be in either an offline mode or an online mode, wherein when in the offline mode said data storage device is permitted to connect in data communication with the host device without being in communication with the remote device over the communications network,
- wherein when in the online mode said data storage device is required to be in communication with the remote device over the communications network before said data storage device is permitted to connect in data communication with the host device,
- wherein when in the online mode said data storage device is associated with an offline occurrence value indicative of a number of occurrences that said data storage device is permitted to connect in data communication with the host device while said data storage device is offline and unable to connect with the remote device over the communications network,
- wherein said data storage device is configured to determine, based on the offline occurrence value, whether said data storage device is permitted to connect in data communication with the host device,
- wherein said data storage device is configured to modify the offline occurrence value upon each occurrence of said data storage device being in data communication with the host device,
- wherein said data storage device is configured to be selectively activated in a standalone mode, wherein when the standalone mode is not activated, said data storage device is configured to restrict data communication with the host device even if said data storage device is permitted to be in data communication with the host device based on the offline occurrence value,
- wherein said data storage device is configured such that if the data storage device receives more than an initial number of permitted mismatched password inputs from the user, said data storage device is powered off,
- wherein said data storage device is configured such that if the data storage device receives more than a maximum number of permitted mismatched password inputs from the user, data stored on said data storage device is deleted or made inaccessible.

A computer-implemented method for authorizing a data storage device to be in data communication with a host device, said method comprising the steps of:
- providing the data storage device, wherein the data storage device is a portable data storage device and includes a secure memory comprising a flash drive or a hard drive, and wherein the data storage device further comprises a keyboard configured to receive password inputs from a user, wherein the data storage device is configured such that if the data storage device receives more than an initial number of permitted mismatched password inputs from the user, the data storage device is powered off, wherein the data storage device is configured such that if the data storage device receives more than a maximum number of permitted mismatched password inputs from the user, data stored on the data storage device is deleted or made inaccessible,
- wherein the data storage device is configured to connect with a remote device over a communications network,
- wherein the data storage device is configured to selectively be in either an offline mode or an online mode, wherein when in the offline mode the data storage device is permitted to connect in data communication with the host device without being in communication with the remote device over the communications network,
- wherein when in the online mode the data storage device is required to be in communication with the remote device over the communications network before the data storage device is permitted to connect in data communication with the host device,
- wherein the data storage device is associated with an offline occurrence value indicative of a number of occurrences that the data storage device is permitted to connect in data communication with the host device while the data storage device is unable to connect with the remote device over the communications network;
- coupling the data storage device with the host device;
- receiving a password via the data storage device;
- determining, based on the offline occurrence value, whether the data storage device is permitted to connect in data communication with the host device,
- wherein the data storage device is configured to be selectively activated in a standalone mode, wherein when the standalone mode is not activated, the data storage device is configured to restrict data communication with the host device even if the data storage device is permitted to be in data communication with the host device based on the offline occurrence value;
- authorizing the data storage device to be in data communication with the host device, and modifying the offline occurrence value.
