  • This invention relates to maintaining the confidentiality of information, and more particularly to an apparatus, method and product produced by such method for ensuring the maintenance of the confidentiality of printed information for the particular purposes described below.
  • U.S. Patent No. 4,912,761 One attempt to resolve this problem, at least from the standpoint of maintaining the confidentiality of documents printed on a facsimile machine, is disclosed in U.S. Patent No. 4,912,761.
  • the apparatus and method described therein is designed to deter the "casual" reader r interposed between the receiver of the transmission, and the intended recipient, from reading the document.
  • the document is divided into two separate documents which are individually unreadable in an easy and straight forward manner.
  • the two separate documents are transmitted in sequence.
  • the portions are then reconstituted at the receiving end by the intended recipient by using a transparency overlay process with the two portions.
  • the patterning at the transmitting end may be accomplished by an optical filtering process or alternatively may be computer generated manipulating a pre-input document to produce the two portions for printing and transmission.
  • This system is, however, intended to deter only the "casual” reader as the separate documents are only unreadable in an “easy and straight forward manner.” Moreover, the system requires scrambling and unscrambling of the original document. As this system only deters the "casual” reader, the need still exists for an apparatus and method which maintains the document in its original form while deterring unauthorized persons from viewing the document from the time it is received at the location of the intended recipient to the time it actually reaches the intended recipient. There also exists a need for an apparatus and method which is adaptable to various office equipment such as photocopiers and printers.
  • confidentiality of printed information contained in a document may be maintained by inserting, enclosing or constructing around the document an envelope or like enclosure and sealing the document in the envelope after the document has been printed.
  • the printed information may be covered by any suitable opaque covering, such as paper, after printing.
  • this invention provides for the maintenance of confidentiality of printed matter contained in a facsimile from the time the document is transmitted from the sender until the intended receiver removes the document from the envelope or other enclosure or covering.

  • the present invention provides, in general, an apparatus and method for maintaining the confidentiality of information contained in a printed document.
  • confidentiality is maintained by sealing the document in an envelope or other suitable covering or package such that the intended receiver of the document may remove the document from the envelope or package without damaging the document.
  • the printed document may be from any source but generally is produced by standard paper handling equipment as well as office equipment such as facsimile machines, photocopiers, computer printers, and the like.
  • the apparatus generally comprises a document confidentiality maintenance device and a controller or control system which automatically controls the functions and sequencing of the document positioner, the document encloser, and the printing device.
  • the confidentiality maintenance device comprises: any form of document printer (e.g. facsimile machine, photocopier, computer printer and the like); a document positioner, which positions the document such that it can be enclosed in an envelope; and a document encloser which encloses the document in the envelope so that the document may be removed from the envelope by the intended receiver.

  • Choice of envelope material is not critical, however, it is a consideration when choosing a means for handling and transporting the material.
  • Various methods of sealing the envelope are suitable for this invention. Although any means to affix paper or other fibrous material together may be employed in practicing this invention, adhesives are preferred. Specifically, heat sensitive and pressure sensitive adhesives are preferred. One such heat sensitive adhesive is available from Imperial Adhesive Corp. of Cincinnati, Ohio, under the trade name "VITEX". VITEX employs a heat activated polymer which is activated between about 160°F and about 180°F. By changing the polymer solution of VITEX, the polymer may be produced to activate at temperatures .as low as about 140°F. Imperial Adhesive Corp. also produces a water soluble latex adhesive which is activated by applying pressure. Either of these adhesives may be employed by the several embodiments described herein. Regardless of the particular adhesive chosen, adhesive may be applied to the envelope material prior to inserting the material into the apparatus or during the operation of the apparatus.

  • Other embodiments of the invention may utilize envelopes which are fabricated by the apparatus of this invention, or by other means, wherein document encloser 18 inserts the document into the envelope instead of fabricating the envelope around the document.
  • the envelope material may be advanced through the apparatus by means similar to the means employed to advance the document paper, as discussed herein.
  • suitable separating means must be utilized. For example, if continuous form paper perforated at pre-set lengths is used, the envelope material may be separated at that point by applying appropriate force to burst the perforation. Of course, no separation means is required if pre-cut lengths of envelope material is used.
  • a suitable means for separating the margins from the envelope material is also a function of document encloser 18.
  • Various means may be utilized for separating the margins depending on whether the margins are detachably connected (e.g. by perforations) to the envelope material. If perforations are present, bursting means may be utilized by applying a force to the detachable connection which is sufficient to detach the margin from the enclosure material without tearing the material. Tractor feeds angled away from the direction of travel of the enclosure material may provide sufficient force.
  • a cutting means, such as a knife may be employed to assist the bursting.
  • other separation means can be employed to separate the margins such as knives or other cutting mechanisms combined with tractor feeds or other devices to carry the margin debris away.
  • Document encloser 18 also may include a label printer for printing information on the envelope.
  • Typical information which would generally be included would be the name of the intended recipient of the document as well as the recipient's address or location. Any other information which is desired to be printed on the envelope may also be included.

  • FIG. 3 The embodiment of the invention depicted in Figures 3, 4, and 5, operates as follows. Individual sheets of printed material ( document ( s ) ) 72 exiting from a printer, such as a facsimile machine, photocopier or computer printer, are deposited on feed chute 20. Sheets 72 slide down web 30 to the point where web 28 comes essentially in contact with web 30 at which point sheets 72 stop and accumulate until the document printing function is complete. Once printed sheets 72 are stacked on web 30, both web 28 and web 30 are advanced by tractor feeds 34 and 36. As the webs advance, label printer 50 prints the desired information on web 28. Webs 28 and 30 are sealed together by a system of rollers 40, 42 and 44, shown in further detail in Figure 5, which press webs 28 and 30 together.

  • the force applied by rollers 40 and 42 is controlled by the spring mechanism shown in Figure 5.
  • the seal on each end of the envelope or package is made by pressure exerted from roller 44. During the time sheets 72 are passing under roller 44, roller 44 is not in contact with web 28. After sheets 72 have passed under roller 44, roller 44 is lowered to contact with web 30 and the requisite pressure required to seal the end of the envelope is applied.
  • the force applied by the center roller may be controlled by the system of springs and electric actuator shown in Figure 5.

  • rollers 40, 42 and 44 press webs 28 and 30 against heater 48, which assists in the sealing of webs 28 and 30. Temperatures and dwell times for such a heating process will vary with the type of thickness of paper and the type of adhesive used. Temperatures of about 160°F up to about 180°F and a dwell time of about 0.5 sec. are typical when Standard Register paper and "VITEX" adhesive is utilized.
