Description

Improved self-destructive documentation for information security and privacy

The fear of data privacy and identity theft is becoming more and more common, and as a result millions of people whose personal or corporate information is stolen or abused suffer unspeakable pain and loss each year. However, while online hacking, phishing, and other computer-assisted theft of personal information have become newspaper headlines, much of that information still remains in the printed material found in trash cans, commonly known as dumpster diving. By extracting personally identifiable information (PII) from communications, it is being stolen in the old way.

Numerous items delivered through typical mailboxes, some of which are requested, others beyond individual control, contain a lot of information on the public side, from names and addresses to other more personal information not intended for public disclosure. In addition, the information contained in medical mail and prescription containers is highly confidential and can be abused. Currently, such articles do not have a quick and simple way of ensuring that such information is destroyed, and the use of information stolen from discarded mails and others remains a major problem, and the present invention provides a solution to this.

In addition, data theft and espionage are becoming more and more common in the industry. Even in offices with strict environmental controls such as a secure intranet and without file storage facilities on sensitive equipment, the need for handwritten notes and temporary memos remains a weak link in non-secure systems.

There are a number of solutions to protect such personal information, but most of them often require separate equipment, such as shredding of paper, or in general, simple paper shredding, the use of concealed stamps and markers, or otherwise. Likewise, it can lead to incomplete deletion of information. In addition, the ability to manufacture and distribute solutions is critical to its usefulness in a highly competitive and cost-sensitive market. Further improvements to the present invention allow for simple mass production using current manufacturing equipment and techniques. Currently available solutions lacking practicality in the real world do not address urgent needs. The inventors disclose herein destructive (e.g., self-destructive or self-destructive) documents, and provide a series of solutions to the theft of personal, medical-related and industrial information, resulting in affordable affordability. , Provide a superior level of manufacturability, privacy and protection.

The present invention provides a series of solutions to the theft of personal, medical and industrial information. In summary, the present invention includes a printable surface referred to as a coversheet. Using a pattern of cuts or perforations, the coversheet is divided into a series of separable island cutouts and residual frameworks, thereby maintaining the integrity of the page, but with the presence of cuts or perforations. Thus, each cutout can be separated from the page with minimal force. To separate the cutout, two additional sheets, including a separation unit, a separator, and a topsheet, are placed on top of or below the coversheet. The separator sheet has a series of small holes arranged to lie over the cutout of the coversheet, and the topsheet is attached to the cutout of the coversheet through the hole in the separator, and in some embodiments, such cutouts are in place. Can help fix it. The separating portion and the topsheet are attached to each other at their periphery and have tabs positioned at one or both ends, a removal tab on the separating portion, and an initiation tab on the topsheet. The separator can also be attached to the coversheet at its periphery to keep the separator unit in place. In order to destroy the document, the separating unit is first freed from the cover sheet using a removal tab, thereby causing the perforated cutout to be detached from the cover sheet, due to attachment to the top sheet. Then, the topsheet is separated from the separating portion using an initiation tab. Since the attached cutout is larger than the hole in the separating portion, the shear force breaks the fixed joint that holds the topsheet to the cutout, and the individual cutouts are separated as a chad. Each chad contains a portion of the original document information and ensures complete removal of the data of the original document. In some embodiments, the coversheet is completely perforated and the cutout is held in place by being attached to the topsheet.

In some embodiments, separation of the coversheet cutout will expose information contained in one or more of the other layers. In some embodiments, the coversheet is attached to an adhesive backing sheet with an optional separating liner, so that the coversheet can be attached to the article as desired. In all embodiments, the present invention allows the printing surface to be destroyed and all readable characters to be removed. Additional details and implementations are described below.

The present invention includes the following elements:

One or more perforated cover sheets,

One or more separator sheets

One or more topsheets.

The present invention also,

May include one or more optional backing sheets, which may include an optional associated release liner in the case of adhesive,

Each of these is described in more detail below, and descriptions of specific preferred embodiments are given below. For the sake of brevity, it is used in the singular form in context to refer to the aforementioned elements, but this may include one or more of the mentioned elements where appropriate.

The first element of the invention comprises one or more coversheets. The coversheet is typically a piece of paper, plastic, polymer, cloth, metal, or other suitable material. One surface includes a recordable or printable surface, on which handwriting, printing, graphics, mailings and other information may be input. In some cases, text may be applied to the coversheet through one or more overlying layers using thermal printing. In some cases, both surfaces may be writable. Coversheets are cut into a series of island contours or "cutouts" using methods, such as die or laser cutting, well known in the art and commonly used in the production of stickers, adhesive labels, stamps, toilet paper, etc. Or perforated. The coversheet can be slightly perforated, or can be freely altered to a fully perforated cutout and held in place by being attached to the topsheet, so that significant force is required to remove the cutout. The cutout may be of the same or different shape and size, and its patterning on the coversheet may be uniform or random, and may cover all or part of the coversheet. The dimensions, size, and shape of the cutout will vary depending on the font type, font characteristics, and font size, document format, etc., and can be selected to maximize data masking. It is possible to optimize these parameters using typical encryption methods for masking the information, thereby ensuring that the information will become uncertain after destruction and that it cannot be reassembled forensically. After separation of the cutout, the portion of the coversheet that remains is known as the residual framework. In some embodiments, the coversheet is attached to the underlying adhesive or non-adhesive backing sheet with an optional separating liner. In some embodiments, the backing sheet is transparent. When the backing sheet is not present, cutting or perforation will be common, so the cutout is substantially separated from the coversheet, but the integrity of the page is preserved, and each cutout has minimal force due to the presence of perforations. Can be separated from the page using only When a backing sheet is present to further support the cutout, an incision/perforation can be made so that the cutout is more easily separated from the backing and coversheet, leaving a residual coversheet grid attached to the lower backing sheet. In some embodiments where a backing sheet is used, the coversheet may resemble a perforated sticker, and the lower surface of the coversheet is the upper surface of the lower backing sheet, formulated as a separating layer, as further described below. And covered with an adhesive that can form a detachable joint. In some embodiments, the coversheet further comprises one or more tabs at one or each end, such tabs may serve to fasten the coversheet ends, and finger retaining portions to help separate the layers from each other ( It can act as a finger hold, or it can be gripped to easily pull the coversheet. The tabs may be of any shape and structure suitable for gripping, and may include flat, reinforced sections incorporated into the coversheet. It may additionally include a mechanism for securing the free end.

A second element of the invention comprises one or more separator sheets, or separators, comprising a pattern of small holes overlapping each cutout on the coversheet. These holes can be of any shape and size and can be placed over the cutout to cause the topsheet to spot adhere to the cutout. Separators are generally transparent, but not always, and after the topsheet and cutout are separated from the coversheet, they act to cut the connection between the topsheet and the cutout, releasing them as a chad. The separation may be the same size as the topsheet or less, but in any case, at least large enough to cover the attachment to the cutout. The detachment may be permanently or temporarily attached at one or more locations and at one or both sides, thereby forming an attachment with the topsheet and/or coversheet retention framework. In some embodiments, the separation may not have a peripheral attachment and may be held in place by a bonding between the topsheet and coversheet cutout. The separator generally has a removal tab at one or more ends, and such removal tabs may be grasped to aid in document destruction and separation from other elements of the invention. The tabs can be of any shape and structure suitable for gripping, and can include flat, reinforced sections incorporated into the separation. In a preferred embodiment, the removal tab is disposed at the end opposite the release tab and can be offset relative to the topsheet or coversheet. It may additionally include a mechanism for securing the free end.

The third element comprises one or more topsheets, which topsheets at least completely cover each hole on the separator and are secured to each cutout through the holes of the intervening separator. Such attachment may be through any suitable means and may include point attachment or other attachment, fusion or any chemical or mechanical bonding method. Such attachment can be of any size, shape and number, so that the cutout is securely fixed to the topsheet through the hole, without attachment to the intervening separator. The topsheet will typically be a sheet of any suitable material, and will typically be transparent, but not always. The topsheet, similar to the tabs described above, further includes one or more release tabs at one or each end, and such release tabs act as finger retaining portions to help detach the topsheet from the other layer. In a preferred embodiment, the release tab is disposed at the end opposite the removal tab and can be offset relative to the separator or coversheet. Pulling the topsheet from the separator using the release tab breaks the bond to the cutout, causing it to separate as a chad. In some embodiments, the topsheet is attached directly to the coversheet retention framework at the periphery, and the detachment is held in place by a fixture between the topsheet and the cutout. In some embodiments, the coversheet is completely perforated and the cutout is held in place by a fixation to the topsheet layer.

A fourth optional element of the present invention includes a backing sheet and an optional separating liner. By including a backing sheet, the document of the present invention can be reinforced or, if desired, attached to the article. The backing sheet includes an upper surface to which the cover sheet can be attached. Characteristically, the top surface has the properties of a separating liner, i.e., HDPE, LDPE and PP plastic resins that can cover all or part of the backing sheet and reliably but temporarily bond to the bottom surface of the coversheet. Such as polyolefin, silicon, polyvinyl alcohol or other suitable ingredients. This aids in adhesion to the coversheet, but allows separation of the subsequent perforated cutout from the top surface of the backing sheet. In some embodiments of the present invention, the backing sheet does not have an adhesive applied to its lower surface, and acts to reinforce the overlapping cover sheet by bonding to it. In another embodiment, the lower surface of the backing sheet includes a second adhesive surface that can be attached to a postal matter or other surface, and is generally protected by a separating liner. In some embodiments, the lower surface may be coated with an adhesive, with or without an optional release liner, and may be attached to mail or other surfaces by any of those techniques known in the art. For example, the lower surface may comprise a simple sticker, typically with a pressure sensitive adhesive covering the surface. The adhesive is protected by a release liner to protect the adhesive before the label is applied, as is common in the sticker industry. Characteristically, similar to the top surface of the backing sheet, the separating liner is made of silicon, polyvinyl alcohol or other suitable ingredients to reduce the tackiness of the surface and to allow it to be reliably but temporarily bonded to the second adhesive coating surface. And a top surface coated with. An attached separation liner can be peeled off from the backing sheet to expose the adhesive application lower surface, thereby aiding in adhesion to mail or other surfaces. Alternatively, the adhesive on the lower surface of the backing sheet may not be covered and may require activation by water, light, temperature, or other means known in the art, in which case the optional separating liner is omitted. Can be.

The exact selection or combination of materials used in the construction of the present invention will depend on the specific application and implementation. Suitable materials are known or will be known to those skilled in the art, and those excluded from the list are not related to their importance in the present invention. In any case, suitable materials and methods are well known in the art, and the following is intended to illustrate, without limitation, the selection of materials that may be used. Typically, the coversheet, backing sheet and separating liner are composed of paper or cardboard, such as pulp or other fibrous products of any wood known in the art. In some embodiments, these elements are made of cloth or other woven material. Alternatively, plastics and other organic polymers can be used. In certain applications, metal foils and alloys may also be advantageous. In certain applications, thermally active materials and thermal printing can be used to print through the overlying layer. Thermal printing can be used to generate a printed image by selectively heating a coated thermochromic paper or thermal paper, and to create an image on a sheet through an overlying or underlying layer. The coating changes color in the heated area, creating an image of one or more colors. Alternatively, heat transfer, laser, inkjet or any other form of printing may be used. Text and images can be applied before, during, or after a roll-to-roll combination of layers, and depending on the embodiment, can appear on both sides of any layer. The top sheet may also be composed of the above-described material, and may be the same or different material as the cover sheet. Likewise, the separators and tabs may be constructed from the various materials listed above. In many applications, one or more layers will consist of a transparent material. Desirable materials can be stored and used in roll form to aid in easy manufacture.

The adhesive can be of any type commonly used in the production of stickers and labels. For example, the adhesive can be permanent, peelable or very sticky. The adhesive chosen for each surface will be best suited for the task at hand. For example, a relatively strong bond is required between the backing sheet and mail to ensure fastening, while a relatively weak bond is required between the backing sheet and the cover sheet to aid in easy separation of the cutout when pulling the topsheet. Can be used. Any materials and methods known in the art that produce a secure bond of the bottom surface to the mail and a releasable bond between the top surface and the coversheet are contemplated within the scope of the present invention.

The exact selection or combination of perforation techniques used in the construction of the coversheet will depend on the embodiment and may be applied before, during, or after the roll-to-roll combination of layers. In some cases, the coversheet will be slightly perforated so that the cutout is firmly attached to the coversheet and a shear force is required between the separator and the coversheet to aid removal. At the other end of the spectrum, the coversheet can be completely perforated so that the cutout is separated from the coversheet for all purposes and held in place by its fixation to the topsheet. This can be achieved using laser cutting during the conversion stage of the roll-to-roll process after the combination of layers and point attachment of the cutout to the topsheet.

The principle advantage of the present invention over current technology is the combination of simplicity and security features provided. Since such an advantage is included in the present invention and does not require separate equipment, the cost is increased to a minimum and there are no additional ongoing costs or requirements. As explained in most cases, the following character breaks, in each of the separate cutouts (chads), in the residual framework, are broken into physically distinct parts. After document destruction, each discrete portion contains a component of characters that cannot be identified by itself, and double security due to the combination of features mentioned herein.

Importantly, the present invention provides a significant improvement for ease of manufacture using current technology over other solutions in the art. Typically, label manufacturers use roll-to-roll processing, also known as reel-to-reel processing or R2R, and a continuous sheet of flexible material (referred to as a web) rolled for more convenient handling and transportation. Use Accordingly, materials such as paper, cloth, plastic film and foil of various weights and lengths may be used in processing machines such as printing presses, laminating, coating and/or cutting/perforating machines to produce intermediate or final products. I can. In this case, each layer of the label is included in a roll, and the layers are combined and manipulated in a process known as transformation. Separate rolls of each layer are provided by machine and bonded as defined by the embodiment using chemical, mechanical, thermal, adhesive or other means. The use of layers allows for customization of label implementations such as pre-printing, the use of thermally active materials for later information application, and the selection of different materials and clarities for different layers. do. Upon completion, depending on the application, the combined layers can be re-reeled to produce an output roll or can be further processed on the same or different machine. Typical conversion techniques include die cutting, laser cutting or other suitable perforation/cutting techniques, and thermal printing or conventional printing. Typical finishing techniques include techniques well known in the art, such as sliting, sheeting, fan-folding, scoring or other processes to provide custom finished labels. Compared to other solutions in the art, the present invention has the advantage that all elements can be included on rolls, can be processed through currently used equipment and are economically competitive in the label manufacturing industry. The roll of each inventive element can be customized with the final printing and perforations already applied, so that the rolls can simply be combined and then cut or processed for dispensing. Alternatively, the input may be blank, or may be prepared for custom data entry and/or perforation during or after the layer combining process. This gives flexibility for a variety of solutions. In order to use other materials such as tape or filament, solid tabs and cutting devices require special machinery and expertise that are not currently on the market.

The small hole 19 in the separating part allows the top sheet 5 to be directly bonded to the cover sheet cutout below, for which reference is made to the insertion diagram (Fig. 1(e)). The separation may be interposed therebetween and held in place by a topsheet-cutout bonding, or may be bonded to the periphery of the topsheet 5 and/or the remaining framework 6 of the coversheet, and various layers can be detached. It may be characterized by one or more release tabs 8 to enable it to be made. In Fig. 1(b), the mailing label 1 is shown attached to the box 12. In Fig. 1(c), the top sheet 5 and the separating portion 7 were removed from the box using the separating tab 8. As the topsheets are dot-attached to the cutout 4, they are separated from the perforated coversheet, leaving a residual framework 6 attached to the box. In Fig. 1(d), the document destruction is completed by detaching the top sheet 5 from the separating portion 7 using the separating tab 8 so that the cutout is separated as the chad 14.

The diagram on the second page shows a further implementation of a device useful for information protection of mail. 2A shows an exploded view of the mailing label 1. The embodiment comprises a thermally activated perforated coversheet consisting of a residual framework 6 and a cutout 4, an optional separating liner 11 that can be attached to a package, container or mail 12 as described above. Having, and a backing sheet 10. In this embodiment, an intervening separator sheet 7 is disposed between the cover sheet and the top sheet 5. Small holes 19 in the separating section (see inset (see Fig. 2(e))) allow the topsheet to be directly joined to the fully perforated cutout to hold them in place. The separator also features one or more tabs 8 which are temporarily bonded to the periphery of the residual framework 6 and/or topsheet 5 and allow the various layers to be detached or separated. In Fig. 2(b), the mailing label 1 is shown attached to the box 12. In Fig. 2(c), using the first separation tab 8, the cover sheet 2, the separation part 7 and the top sheet 5 having the cutout 4 and the residual framework 6 are It has been removed from the box and a backing sheet 10 is attached to the box.

As the print is distributed over the entire surface of the document, by removing the cutout and the information printed thereon, the print remaining on the residual document framework becomes incomprehensible. The security document of the present invention is suitable for all types of confidential information.

The diagram on the fourth page shows an implementation example of a device used for protection of prescription and medical information. The label of the present invention is affixed to the prescription container 15. This embodiment is for separating and destroying the cover sheet 2 including the residual framework, perforations 3 and cutouts 4, as well as the top sheet 5 and the separating portion 7, and the label. It includes the elements listed above, including one or more tabs 8. This embodiment is useful for all labeled medical products, including hospitals, laboratories, blood banks, inpatient and outpatient prescriptions, law enforcement statements, and all other cases where medical information may be at risk.

The diagram of FIG. 5 on the fifth page shows the use of multiple label panels 17 integrated into a single sheet 16. The elements of the invention have been described above and include a perforated coversheet 2 and cutout 4, a separator 7, a tab 8 and a topsheet 5. As the backing sheet and separating liner 11 are perforated at the edges of each panel, the labels can be applied independently in each case. In the figure, six panels each containing a duplicate copy of the label are shown as one sheet. In the lower right, a panel with a set of replica labels 17 is shown partitioned from the sheet 16. Each panel may include one or multiple topsheets such that separation of the topsheet results in destruction of information from only one portion of the panel, but leaving information on the bottom portion undamaged for later purposes. Thus, each topsheet can be used independently to separate the cutout from one or more portions of the coversheet, while leaving adjacent characters intact for later use.

The diagram of Figure 6 on page 6 shows the mass production of the present invention using current commercial technology. When using roll-to-roll manufacturing, the top sheet 5, the separator sheet 7, the cover sheet 2, and the backing sheet 10 with the separator liner 11 are suitable adhesives or Combined together, using fusion techniques (20). After the combination of the layers, other conversion techniques can be used including thermal or conventional printing and/or die or precision laser drilling (21). The final step involves finishing 22, where the rolls can be divided, cut, or otherwise processed to produce the final embodiment. Depending on the implementation, the coversheet 2 may be pre-printed with information, or a thermally active surface may be used so that the information can be applied to the label during conversion 21 or later. In some embodiments, the backing sheet 10 and/or the separating liner 11 are omitted.

Description of implementation

It will be understood that the drawings, embodiments, and implementations described herein are for illustration only, and various changes or changes taking them into account will be presented to those skilled in the art and are included within the spirit and scope of the present application and the scope of the appended claims. The following examples are provided for illustrative purposes, but do not limit the claimed invention, and none of the limitations implied in the exemplary embodiments should be considered limiting of the claims. All publications, patents, and patent applications cited herein are incorporated herein by reference in their entirety for all purposes.

As the invention includes certain optional elements, the invention can be adapted to each desired use. The backing sheet and associated separating liner are optional elements of the present invention, and their inclusion or exclusion in each embodiment depends on the selected application. In addition, the topsheet and separator may be placed under or over the coversheet, and numerous mechanisms for attachment of the topsheet, separator and/or tab are contemplated.

Example 1: This example provides a solution to the theft of personal information from discarded mail and containers and uses a topsheet, with a separator sheet disposed between the coversheet and the topsheet. As shown in Fig. 1(a), the present invention provides a mailing label comprising a thermally active coversheet, and a backing sheet having a separating liner, which can be attached to a package, container or mail. A separator is placed over the coversheet, and such a separator covers the recordable portion of the coversheet and has a small hole aligned above each of the cutouts, temporarily attached to the coversheet residual framework below, in all or part of the perimeter. do. A removal tab located at one end of the separating portion allows the separating portion/topsheet sandwich to be detached from the coversheet, thereby causing the cutout fixed to the topsheet to be removed from the coversheet. A top sheet of at least the same size as the separating portion is positioned on the separating portion, and the separating portion is offset relative thereto to facilitate access to the protruding separating tab. The topsheet is fixed to the cutout of the coversheet through small aligned holes in the intervening separator, and temporarily adhered to the lower separator at all or part of the periphery. In this embodiment, using thermal printing, characters can be applied to the coversheet through the topsheet and the separator above. Alternatively, in the absence of a backing sheet, the character can be applied to the lower surface of the coversheet, and the present invention inserted into the transparent mailing pouch character side is seen. After removing the separating portion, the top sheet and the attached cutout from the cover sheet using the removal tab, the label is broken by pulling the tab to separate the top sheet and the separating portion. A shear force is created and the cutout cannot pass through the small hole in the separation, so the joint to the topsheet is broken and the cutout falls off as a random chad. As the document information is now destroyed by the coversheet residual framework and numerous shades, the remaining prints become incomprehensible.

Example 2: This example provides a solution to the theft of personal information from discarded mail and containers and utilizes a top sheet, with a separation portion disposed between the cover sheet and the top sheet. As shown in Fig. 2A, the present invention provides a mailing label comprising a thermally active coversheet, and a backing sheet having a separating liner, which can be attached to a package, container or mail. A tab located at one end of the coversheet allows the coversheet, separator and topsheet sandwich to be separated from the adhesive backing sheet and packaging. Above the cover sheet is located a separation portion, such a separation portion covering the recordable portion of the cover sheet and has a small hole aligned above each of the cutouts. The cutout, after layer combination, was completely perforated using laser cutting and held in place relative to the topsheet by point attachment. The separating portion may be temporarily bonded to the underlying cover sheet residual framework at all or part of the periphery. Above the separating portion, a topsheet, fixed to the cutout through an aligned separating portion hole, is positioned, and the topsheet may additionally be temporarily fixed to the lower separating portion at all or part of its periphery. The topsheet is at least the same size as the separator, and is often offset relative to it to provide easy access to the protruding release tabs. In this embodiment, using thermal printing, characters can be applied to the coversheet through the topsheet and the separator above. Alternatively, in the absence of a backing sheet, the character can be applied to the lower surface of the coversheet, and the present invention inserted into the transparent mailing pouch character side is seen. After removing the separator, topsheet and attached cutout from the coversheet using the removal tab, the label is broken by pulling the tab to separate the topsheet from other layers. A shear force is created and the cutout cannot pass through the small hole in the separation, thereby breaking the fixed joint to the cutout and they fall off as random chads. As the document information is now destroyed by the coversheet residual framework and numerous shades, the remaining prints become incomprehensible.

Embodiment 3: This embodiment provides a solution to the theft of corporate information, e.g. communications generated within a controlled work environment. As shown in Fig. 3(a), the present invention includes a cover sheet having a suitable recordable surface, a separator and a top sheet, and one or more tabs. In some embodiments, the cutout is held in place by being completely perforated from the coversheet using laser cutting after the combination of the layers and attached to the topsheet. An intervening separator sheet is placed between the cover sheet and the top sheet and is permanently attached to the residual framework around the periphery. After the text is added, the document can be destroyed by pulling the tab of the separator. As the separation is bonded to the coversheet, and as the cutout is already laser cut from the coversheet, the shear force generated by pulling the tab causes the fixed joint between the topsheet and the cutout to be cut, and the cutout as a separate chad. It is separated and the information on the document 1 is destroyed. In an alternative embodiment, the separator is temporarily bonded to both the coversheet and topsheet, and the cutout is the coversheet so that the separator and topsheet provide support for the perforated coversheet and the page maintains integrity and usability prior to separation. Is only slightly perforated from When breaking, pulling the separating portion and cover sheet tab pulls the separating portion/top sheet away from the cover sheet, and since the top sheet is fixed to the cutout through a hole in the separating portion, the perforated cover sheet due to the shear force generated The cutout is detached from Next, pull these two layers away using the tabs on the topsheet and separator. Since the hole in the separation portion is smaller than the cutout, the junction between the topsheet and the cutout is cut, and the cutout falls off as a separate chad. As the print is distributed over the entire surface of the document, by removing the cutout and the information printed thereon, the print remaining on the residual document framework becomes incomprehensible. In some embodiments, the label may include a single panel with one or more instances of the invention, or may have multiple panels each featuring zero or more instances of the invention. The panels can be bonded or present as individual components. By providing a fast, simple and integrated system to remove all identifying information from confidential documents, the present invention provides enterprises with a way to protect the information of the enterprise or its customers from acquisition and abuse. Ease of use and compliance are maximized, as no separate equipment is required and destruction can be achieved at the current location. The label of the present invention is easily manufactured using currently available technology, and is not limited to letters, documents, notes, memos, drawings, graphics, sketches, graffiti, graffiti, cards, sheets, rolls, rims and images. It is suitable for all forms of confidential communication, including.

Example 4: This example provides a set of solutions to theft of personal, industrial and medical information. As described above, the present invention includes a cover sheet, a top sheet, a separator and an adhesive backing sheet, the backing sheet to be attached to any article containing personal medical information, e.g., a package, container, document or mail. I can. This embodiment includes all of the elements of Example 2 and allows removal of the entire label from the medical container. In an alternative embodiment, the backing sheet and separation liner can be omitted, and the coversheet is attached directly to the container such that the coversheet residual framework remains attached to the container after document destruction. In some embodiments, the release tab can be a reinforced extension that is integrated into the topsheet and lies flush with the coversheet, thereby providing a uniform surface for printing after being attached to the container. In a preferred embodiment, the topsheet is offset relative to the coversheet, thus allowing easy access to the tabs. In a further preferred embodiment, the label may comprise a single panel with one or more instances of the invention, or may have multiple panels each characterizing zero or more instances of the invention. Panels may be contiguous or present as individual components. After the advancement of genetic science and the subsequent introduction of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 (HIPAA), the need for better patient information security is greater than ever. This embodiment is particularly suitable for use in the protection of prescription and patient information on medications, containers, labels, prescriptions and other articles containing such sensitive medical information.

Example 5: This example provides an overview for making the present invention on a commercial scale using currently available technologies. Roll-to-roll processing is commonly used in the manufacture of labels and is readily used for the present invention as shown in FIG. 6. Separate rolls of each layer are provided by machine and bonded as defined by the embodiment using chemical, mechanical, thermal, adhesive or other means. After bonding, depending on the application, the combined layers can be re-reeled to produce an output roll or can be further processed (transformed) on the same or different machine. Typical conversion techniques include die cutting, laser cutting or other suitable perforation/cutting techniques, and thermal printing or conventional printing. Typical finishing techniques include techniques well known in the art, such as sliting, sheeting, fan-folding, scoring or other processes to provide custom finished labels. In some embodiments, the coversheet is pre-printed, while in other embodiments, a roll of thermally active material is used so that the information can be applied at a later time. In some embodiments, a backing sheet with a separating liner is omitted. In some embodiments, the topsheet and separator may be supplied as a transparent roll. In some embodiments, after the cutout is secured to the topsheet, the coversheet is completely perforated using a precision laser. Compared with other solutions in the art, the present invention has the advantage that all elements can be included on a roll, can be processed through currently used equipment, and are economically competitive in the label manufacturing industry. Rolls of each inventive element may be custom prepared for lamination of the final product, or may be blank and prepared for perforation and custom data during or after the lamination process. This gives flexibility for a variety of solutions. In order to use other materials such as tape or filament, solid taps and cutting devices require special machinery and expertise that are not currently on the market.
