Scrambler of information stored on magnetic memory media

Abstract

A device for scrambling the information held by magnetic memory storage media and rendering the information inaccessible. The portable device provides a passage through which a magnetic memory storage medium, also known as a diskette, passes in such proximity to magnetic material so that the magnetically sensitive components of the memory storage medium are thereby disordered by the force of the magnetic field emanating from the magnetic material.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the security of information stored on magnetic memory storage media from unauthorized use, specifically a device to permanently prevent the unauthorized access to information stored in memory by said media. The invention is a device for scrambling the information stored by magnetic memory storage media and rendering the information stored by said media inaccessible. The portable device provides a passage through which a magnetic memory storage medium passes in such proximity to other magnetic material so that the magnetically sensitive components of the memory storage medium are disordered by the force of the magnetic field emanating from the other magnetic material.

1. Background Information

Magnetic memory storage media, commonly and hereinafer referred to as diskettes, are typically used as vehicles to transfer information from one computer system internal memory storage drive to another computer system internal memory storage drive. Once the transfer of information from a diskette onto the second computer system internal storage device is completed, the information remains stored on the diskette. Diskettes are also typically used to store information copied from an internal memory storage drive in order to back-up the information in the event the information stored internally is lost, destroyed or otherwise rendered inaccessible. In either event, the information stored on the diskette can be either casually or intentionally accessed by unauthorized persons. The information can be accessed from the diskette with or without the use of the underlying control program or a program converter. Therefore, when an information transfer to or from a computer system internal memory storage drive by diskette is completed, or before any diskette storing confidential information is disposed, the information stored on the diskette needs to be rendered inaccessible for security reasons before the diskette is either lost, misappropriated, or disposed which would leave the information on the diskette accessible either by personnel, the public or other unauthorized parties.

Once information is stored on a magnetic memory storage medium, and the purpose of the storage is completed, the diskette is typically then either transferred, left unattended, or discarded with minimal or no security measures taken to guard the stored information against unauthorized access to the stored information. Examples of existing security measures for information on diskettes include limited access to the area of the physical storage of the diskette, and physical destruction of the diskette. Customarily, no security precautions are taken prior to further handling or disposal of diskettes.

Another perceived security option to supposedly protect information on diskettes is deleting information files on diskettes by computer system control programs. However, such action demands interruption of work, insertion of the diskette into the computer system, selection of control programs, selection of information storage files, engagement of the diskette drive mechanism, then removal of the diskette. Also, these procedures do not "clean" the memory storage sectors on a diskette but only mark them as being unused. The supposedly deleted information files can be reconstructed or rejuvenated by other computer system control programs.

These security lapses are solved by the invention.

DISCLOSURE OF INVENTION

Brief Summary of the Invention

The preferred embodiment of the invention quickly and permanently disrupts and disorders the magnetically sensitive components of the memory storage medium (diskette) so that any information stored by said medium is scrambled and rendered inaccessible. The device is portable and convenient to use, taking approx. 2 seconds to scramble information on an entire diskette. The device expediently and permanently enables an effective precaution to ensure that no information is accessed, transferred or absconded via discarded or carelessly handled diskettes.

Also, the device allows the scrambled diskette to be used again by a computer system to store information. For example, a manager could scramble confidential information, then give the diskette to support staff to use again without the risk that staff will access the theretofore confidential material on the diskette before re-use. The device also results in cost savings by not having to acquire new diskettes for those diskette consumers who would otherwise choose to destroy or discard the diskette at this point for security reasons. The device also saves wear and tear on the diskette drive of the computer system for those who would otherwise elect to engage the diskette drive mechanism to supposedly delete information files. For diskette users seeking an environmentally sensitive alternative to the disposal of plastic diskettes, the device will allow diskettes to be repeatedly recycled with each successive last user scrambling the diskette with the invention. In any event, the ease of such a security action enabled by the device program will encourage diskette users to become more security conscious by easily, swiftly, effectively and permanently scrambling information stored on diskettes.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Detailed Description

Referring now to the drawings in detail, the frame (FIG. 1A) provides enough volume 1 so as to allow the magnetic material (FIG. 1B) to fit inside the frame. After the magnetic material is inserted into the frame a cover (FIG. 1C) is placed over the top surface area of the magnetic material. The purpose of said cover is to prevent erosion of the magnetic material by the friction of the passing diskette and to prevent particles of magnetic material from attaching to or collecting on the diskette. The cover must be sufficiently thin and of material so as to not significantly suppress the magnetic field. Assembly is completed by placing and affixing the top with downward extending perpendicular sides (FIG. 1D) which sides are also the sides of the passage space 2 over the frame, magnetic material and cover, leaving only enough passage space 3 (FIG. 2) to allow a diskette 4 to be inserted into the space and to pass through the space (FIG. 3).

FIG. 4 illustrates a partial cross-section of the device and FIG. 5 is an isolated close-up view showing the layering of the cover 5 on the magnetic material 6 below the space 7. The frame and top can be fabricated from a wide range of materials including plastic, wood and metals.

OPERATION

The diskette is manually inserted into the space and pulled out the other side of the space with the entire diskette having been caused to make contact with and slide over the cover and pass through the magnetic field emanating from the magnetic material. Once the diskette exits the space after making contact with and sliding over the cover and having passed through the magnetic field emanating from the magnetic material, the magnetically sensitive components of the diskette are disordered thereby scrambling the information stored on the medium due to the effect of said magnetic field.

SCOPE

Although a particular and preferred illustrative embodiment of the present invention has been described herein with reference to the accompanying drawings, the present invention is not limited to this particular embodiment. Various changes and modifications may be made thereto by those skilled in the art without departing from the spirit or scope of the invention. For example, the invention can be affixed to a container to collect and store the diskettes after they pass through the invention.

Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
