## Title
Location based secure data device

## Abstract

In providing secure data access, a secure data device receives a data access request to access secured data stored in a storage of the secure data device. A location module of the secure data device calculates a current location of the secure data device. A secure data module of the secure data device compares the current location and a pre-stored location stored in the secure data device. Upon determining that the current location matches the pre-stored location, the secure data module retrieves the secure data from the storage and processes the secure data. The processed secure data is sent as available data in response to the data access request. Upon determining that the current location does not match the pre-stored location, the secure data module retrieves the secure data and processes the secure data in a manner that renders the available data unusable.

## Background
BACKGROUND OF THE INVENTION
Field
This invention relates generally to security, and more specifically, to a secure device storing data.
Related Art
People have been storing important or valuable objects and documents in sentry boxes, safes, safe deposit boxes, or safe rooms. These containers provide strong physical protection to prevent theft of the content inside the containers. They are often secured physically to a fixture or building structure. Better locks, improved materials and more secure procedures have been developed over time. However, things are changing in past several decades, particularly changes regarding the important and valuable content people want to protect.
More and more information and documents are now created and stored digitally. Many important documents like birth certificates, vehicle registration, passwords, wills, medical records, personal financial records are now in digital form. Many electronic documents or assets are valuable, such as family photos, manuscripts, writings, and digital paintings. These important or valuable electronic objects or documents cannot be stored or secured in the same manner as with a sentry box or a safe deposit box. Today, we store them in a network computer in a public or private network provided by a service provider, or store them in our computers. The safety provided by a sentry box or a safe deposit box is not available for these computers. Once a computer is stolen or hacked, the information stored in the computer is subject to theft.
It would be desirable for a bank, for example, to allow Mary to store her electronic will that can only be accessed in the bank. In another situation, John has many online accounts and creates an electronic document file storing all the passwords of the accounts. John stores the password file in his laptop computer. John wants to be sure the password file will be safe. John wants his laptop computer to only be able to review the password file while located in his home office. In a similar way, John owns a jewelry shop and maintains an important client list. John wants the client list be accessible only in his shop. This way, John can prevent any employee in his shop from accessing the client information even if the client list document file is stolen and taken outside the shop.
In a different situation, Mary's employer allows Mary to use her mobile phone to access corporate financial documents. The employer requires the financial documents only be accessible by her mobile phone when Mary is in the office.
The above scenarios illustrate the need to provide security for electronic data using location information.
BRIEF SUMMARY OF THE INVENTION
According to one embodiment of the present invention, in a method for secure data access, a secure data device receives a data access request to access secured data stored in a storage of the secure data device. A location module of the secure data device calculates a current location of the secure data device. A secure data module of the secure data device compares the current location and a pre-stored location stored in the secure data device. Upon determining that the current location matches the pre-stored location, the secure data module retrieves the secure data from the storage and processes the secure data.

In one embodiment, secure data device 300 converts secure data 602 using current location 331 or pre-stored location 335. In one embodiment, secure data device 300 uses current location 331 or pre-stored location 335 as secure key 122, and uses secure key 122 to convert secure data 602. In one embodiment, secure data device 300 combines secure key 122 and current location 331 or pre-stored location 335 to generate a different secure key and uses the generated secure key to convert secure data 602. In one embodiment, current location 331 is not the proper location in which to access secure data 602; as a result, the generated available data 622 does not show a piece of data expected by the requester 101. In this embodiment, generated available data 622 may not be legible, may contain patterns not recognizable by requester 101, may not be displayable, or may contain audio/video not decipherable by requester 101. In one embodiment, generated available data 622 may contain benign information misleading requester 101 that requester 101 has proper access to secure data 602.
In one embodiment, secure data module 303 presents available data 622 on an output peripheral of secure data device 300 such as a display, an audio speaker, a light indicator, or any output module. In one embodiment, secure data module 303 presents available data 622 onto a network module of secure data device 300, a data interface connector such as a USB interface, a HDMI interface, a DVI interface, a Firewire interface, or other interface allowing data 622 to be transferred via the interface.
