Description
TECHNICAL FIELD The subject disclosure relates to an identity document data protection tool, a passport and a method of protecting data of an identity document.
BACKGROUND ART Identity fraud and theft is a serious form of crime that is receiving more and more attention. Personal data are stolen by criminals and misused for financial gain. For example, goods can be bought by criminals under the name of another person. In order to reduce the chance of becoming the victim of this type of fraud, it is advisable to be careful when exchanging personal data with third parties.
During holidays and business trips it is often necessary to identify yourself. For example, hotels often want to copy guests! identity documents, such as a passport. However, for identification it is not necessary to share the most basic information such as the national identification number (NIN), in the Netherlands known as citizen service number (CSN) and in Dutch burgerservicenummer (BSN), and passport photo, even if this is stated on an identity document. It is desirable to protect this sensitive information and to prevent its disclosure to third parties.
To prevent identity fraud, passport covers have been developed to hide fraud-sensitive information, such as national identification number, passport photo and document number, but still allow the necessary information to be displayed for identification purposes. A problem with these passport sleeves is that they clearly show that information is hidden. In order to ensure that all the essential information for a company to prove the identity of a person receiving a service or product, e.g. a hotel or rental business, is included on the copy, a receptionist will simply remove the identity document from the sleeve, copy it, and slide it back into the sleeve.
EP3400826A1 describes a passport cover for securely covering a passport. The passport cover comprises a first cover part with a first inner wall and a second cover part with a second inner wall. The first inner wall and/or the second inner wall comprises a transparent area to display a first type of information and an opaque area to conceal a second type of information. An inlet allows placing of the passport into the passport cover. A sealing unit is provided to close the inlet, and the sealing unit is configured to be held in a closed sealing position by a tamper evident seal. An advantage of the cover is that one can see when the passport has been removed from the cover. However, when the passport has been removed from the cover, a new tamper evident seal has to be used to hold the sealing unit in a closed sealing position.
SUMMARY OF INVENTION It is an object of the present technology to provide an improved identity document data protection tool, which overcomes at least one of the disadvantages of the tools described above. According to an aspect of the subject technology, this object is achieved by an identity document data protection tool having the features of claim
1. Advantageous embodiments and further ways of carrying out the present technology may be attained by the measures mentioned in the dependent claims. An identity document data protection tool according to the subject technology comprises a sheet attached to a non-stick liner. The sheet is configured to be attached to a specific type of identity document comprising at least one unique visible data element. Portions of the sheet are provided with copy protection elements such that a main part of the at least one unique visible data element can be captured by an image capturing device and a remaining part of the at least one unique visible data element cannot be captured by the image capturing device when the sheet is attached to the specific type of identity document. The concept of the present technology is that the person-related information that may be used in identity fraud is partially protected so that this information is not completely present on the copy, but that there is enough information visible so that the person who wants to make a copy of an identity document does not tend to remove the sheet before copying, because he or she cannot see all the information that he or she considers necessary. This can be done, for example, by covering only a limited number of characters of the citizen service number and/or some parts of the passport photo with the sheet.
In an embodiment, a first unique visible data element is depicted twice on the identity document by a first and a second representation of the first unique visible data element and wherein the portions of the transparent sheet prevent capturing of corresponding parts of each representation of the first unique visible data element. This property ensures that it is not possible to combine the information from the two representations on the identity document in order to derive the complete information. In a further embodiment, the first and second representation of the first unique visible data element have a dimensional ratio and wherein on the transparent sheet the portions of corresponding parts of the first and second representation have a corresponding dimensional ratio. For example, when a photograph is on the identity document in a large and small format, this feature ensures that almost the same part of both photographs is visible and hidden.
In an embodiment, the first representation of the first unique visible data element is visible on the front side of the identity document and the second representation of the first unique visible data element is visible on the back side of the identity document and the identity document data protection tool further comprises another sheet. The portions with copy protection elements on both sheets are located on substantially the same location. The locations of the portions are such that when one of the sheets is attached to the front or backside of the identity document the portions prevent capturing of a similar part of the first representation or the second representation. This feature has the advantage that a user cannot make a mistake when attaching the two sheets to both sides of the identity document. In both cases, the same information or characters of an information item are hidden on both sides.
In an alternative embodiment, wherein the identity document comprises a front side and a back side with a first unique visible data element on the front side and a second unique visible data element on the back side, the sheet comprises a front side cover sheet section, a back side cover sheet section and a folding structure between the front side cover sheet section and the back side cover sheet section. The front side cover sheet section comprises at least one copy protection element to cover partially the first visible data element and the back side cover sheet section comprises at least one copy protection element to cover partially the second visible data element. The folding structure enables to align the sheet on the identity document and to fold the sheet around an edge of the identity document.
In an embodiment, one side of the transparent sheet is covered with a silicone adhesive layer. Silicone adhesive enables easy application on a smooth surface. It maintains consistently low adhesion over long periods and therefore provides easy removal and replacement when required without damaging the identity document.
In an embodiment, at least one side of the transparent sheet is covered with a silicone polymer based adhesive layer. Silicone polymer based adhesive enables easy application of the tool on a smooth surface in a non- permanent way that allows removal. It maintains consistently low adhesion over long periods of time and therefore provides easy removal and replacement when required without damaging the identity document and/or the tool.
In an embodiment, the copy protection element of at least one of the portions of the sheet is a non-transparent ink layer. Printing is an easy and inexpensive process to make portions of the sheet non-transparent.
In an embodiment, the unique visible data element is a string of characters having a background colour. A portion of the sheet prevents capturing at least one character of the string of characters and has at least at its edges a colour corresponding to the background colour of the at least one character. This feature masks that one or more characters of a string of characters on the identity document are hidden by the sheet.
In an embodiment, at least one of the portions of the transparent sheet is obtained by applying light-reflecting particles in and/or on the transparent sheet. When a copy is made with a scanner, the light reflection of the particles will cause the image at that location to be overexposed, making the underlying data not visible on the copy.
In an alternative embodiment, at least one of the portions of the sheet is obtained by attaching non-transparent stickers on the sheet. In the context of the present application, a sticker is non-transparent when an image capturing device is not able to capture the information part of the identity document covered by the sticker. The non-transparent sticker may be a metal sticker.
In an embodiment, at least one of the portions of the transparent sheet is obtained by applying a different refractive index at locations of said at 5 least one of the portions. In this way it is possible that there is no viewing angle under which all the information on the document is visible at the same time, while it is possible to see all the information by varying the viewing angle.
In an embodiment, the specific type of identity document comprises multiple pages, and the transparent sheet with portions has to be attached to a side of a page of the specific type of identity document comprising the at least one unique visible data element, the identity document data protection tool further comprises an instruction sheet with an adhesive layer configured to be attached on a page located opposite the page on which the transparent sheet has to be attached. By explaining on the opposite page in the identity document why certain parts have been made invisible, the chance that the sheet will be removed during copying or passport-checking is reduced. The explanation may be given in a number of languages.
In a second aspect, there is provided a passport comprising a sheet configured to overlay a page of the passport comprising at least one unique visible data element. Portions of the sheet are provided with copy protection element such that a main part of the at least one unique visible data element can be captured by an image capturing device and a remaining part of the at least one unique visible data element cannot be captured by the image capturing device when the sheet is overlaying said page of the passport comprising the at least one unique visible data element.
In a third aspect, there is provided a method of protecting at least one unique visible data element on an identity document, the method comprises the actions: - providing an identity document data protection tool described above; - removing the sheet from the non-stick liner; and - attaching the sheet to the identity document such that a main part of the at least one unique visible data element can be captured by an image capturing device and a remaining part of the at least one unique visible data element cannot be captured by the image capturing device.

Fig. 2A schematically shows an embodiment of an embodiment of an identity document data protection tool according to the subject technology; Fig. 2B schematically shows application of the identity document data protection tool shown in Fig. 2A; and, Fig. 3 schematically shows a passport with a data protection sheet integrated in it.
DESCRIPTION OF EMBODIMENTS Fig. 1A schematically shows a front view of an identity document
100. An identity document in the present disclosure is any document which may be used to prove a person's identity. Examples of an identity document include, but are not limited to: an identity card, passport, national identification card, regional identification card, and driver's license. The identity document is used to connect a person to information about the person, often in a database. The photo 102, 104 on the identity document 100 and the possession of it by a person is used to connect the person with the document. The connection between the identity document and information is based on personal information present on the document, such as the bearer's full name, age, birthdate, address, an identification number, card number, citizenship and more. A unique national identification number 106 is assigned to each person and is mostly used to define a unique link between a person and a database. A unique visible data element in the context of this disclosure is any of the personal data on the document that is unique to that person and that is perceivable by a human being or device. A QR-code or Bar- code on the identity document which is generated by using personal data may also be a unique visible data element.
Each type of identity document has its own layout. So a passport and driver's license are different types of identity documents. Furthermore, the layout of a particular type of identity document changes over time. The position of for example the photo on a passport and national identification number may be different on subsequent versions of the passport. In the context of the present disclosure, the term “specific type of identity document” refers to an identity document with a known layout. The position of a unique visible data element on a specific type of identity document is fixed for said specific type of identity documents.
Fig. 1B schematically shows a front view of an embodiment of a sheet 200 according to the subject technology. The majority of the sheet is transparent and some portions or regions are provided with copy protection elements such that a main part of the at least one unique visible data element can be captured by an image capturing device and a remaining part of the at least one unique visible data element cannot be captured by the image capturing device when the sheet is attached to the specific type of identity document. The remaining part corresponds to the parts that are covered by the copy protection elements. This is illustrated by Fig. 1C which schematically shows a front view of the identity document shown in Fig. 1A to which the embodiment of the sheet shown in Fig. 1B is attached. An image capturing device may, but is not limited to a scanning device, photocopying machine, a photo camera and mobile phone camera.
Portions 202 protect four small parts of the photograph for photocopying. Portions 204 protect similar parts of a smaller photograph on the identity document for photocopying. The dimensions and position of the portions 202, 204 are chosen such that a human can verify while the sheet is on the identity document whether the person wearing the identity document is the same as the person in the photograph and where the person does not have the need to remove the sheet as there is still a quantity of image data missing. In this embodiment, a first unique visible data element, the photograph is depicted twice on the identity document by a first representation 102 and a second representation 104 of the first unique visible data element and wherein the portions 202, 204 of the transparent sheet prevent capturing of corresponding parts of each representation of the first unique visible data element. The first and second representation 102, 104 of the first unique visible data element have a dimensional ratio. The main difference is the size of the photograph and not the content. On the transparent sheet the portions 202, 204 of corresponding protected parts of the first representation 102 and second representation 104 of the first unique data element have a corresponding dimensional ratio. In this way, similar portions of the same photograph are hidden for copying. Consequently, it is not possible to reconstruct a full photograph by combining the image information from both photographs. In the present embodiment, the portions 202 covering small parts of the large photograph 102 and the portions 204 covering small parts of the small photograph 104 have a similar shape. In another embodiment, the portion 202 and 204 have the same size and are positioned such that the portions 204 cover at least the portions in the small photograph corresponding to the portions of the large photograph that are covered by the portions 202. In another embodiment, the shape and/or the size of the portions 202 and 204 are different, but cover at least some similar portions of the first and second representation of the person by the photograph.
Portion 206 protects a part of the national identification number 106 for copying. This unique visible data element is a string of characters having a background colour. A portion prevents capturing at least one character of the string of characters. The portion may have a colour corresponding to the background colour of the characters that are covered by said portion. In an embodiment, the edges of the regions have a colour corresponding to the background colour of the at least one character. The portions provided with copy protection elements prevent to make a copy of the part of the identity document that is covered by the portions. A copy protection element may be a non-transparent ink layer provided on a transparent sheet by means of a printing process. The ink layer on the sheet makes said portions of the sheet opaque. It might also be possible that at least one of the portions of the sheet is obtained by applying light-reflecting particles in and/or on the sheet. Now, the information covered by the region with light-reflection particles can be seen by a human. However, when making a copy with a scanning device, the light reflecting particles will reflect the light of the scanner. As a result the area of the regions with light-reflection particles will be overexposed so that the data of the identity document that is covered by said regions is not readable on the photocopy of the identity document. In an alternative embodiment, sheet 200 is obtained by providing a transparent sheet to which non-transparent stickers are affixed. In another embodiment, at least one of the portions of the data protection sheet 200 is obtained by applying a different refractive index at locations of said at least one of the portions with a commonly known process. In this embodiment, there is no possibility to see all information on the sheet at only one angle of view. At different viewing angles, a person will view other parts of the identity document. Other processes to provide the copy protection elements on the data protection sheet are: any suitable printing process, pasting with stickers, screen printing, blurring, applying light-reflecting flakes, embossing and any other process suitable to change the characteristics of the sheet in such a way that the content of at least one unique visible data element is not fully visible at any viewing angle. Fig. 2A schematically shows an embodiment of an embodiment of an identity document data protection tool 300 according to the subject technology. The identity document data protection tool comprises a non-stick liner 302 on which data protection sheet 200 is attached and also an instruction sheet 400. Both the data protection sheet 200 and instruction sheet 400 may comprise an adhesive layer to attach the sheets to the non-stick liner. Any suitable adhesive layer may be used, preferably one which does not damage the identity document when the data protection sheet 200 has to be temporarily removed from the identity document and can be reapplied to the identity document after removal. A silicone adhesive layer has been found to be very suitable for this purpose. The sheets may also be made from a static material with a stable static charge. It may also be possible for the data protection sheet to be attached to the identity document by means of a vacuum between the sheet and document.
Fig. 2B schematically shows application of the identity document data protection tool shown in Fig. 2A. The specific type of identity document is a passport 500 in the form of a booklet.
The data protection sheet 200 is attached to the page side comprising the unique visible data elements and the instruction sheet 400 is attached to the opposite page side when the booklet is opened.
The instruction sheet explains that the passport is provided with a data protection sheet that covers partially some data elements against identity fraud, while still having the necessary data to identify the person of the passport.
The explanation may be given in a number of languages.
In this way, the human checking the identity of the person by means of the passport, can read why some parts of the photograph and national identity number are not visible as they are hidden by the data protection sheet 200. When a copy is made from the identity document to which the data protection sheet is attached, the content of the photograph and national identity number is not fully available on the copy.
On some types of identity documents, the national identity number 106 is present on the front side and the back side of the document.
For such identity documents, the identity document data protection tool comprises two sheets, one sheet to hide portions of a unique visible data element on the front side and one sheet to hide portions of the same unique visible data element on the back side of the identity document.
The portions of the first sheet to hide portions of a unique visible data element on the front side and portions of the second sheet to hide portions of said unique visible data element on the back side may differ in position and shape and thus be designed for especially the front side and the back side.
In another embodiment, the copy protection elements on both data protection sheets are located on substantially the same location.
The locations of the portions are selected such that when one of the sheets is attached to the front or backside of the identity document the portions prevent capturing of a similar part of the first representation on the front side or the second representation on the back side.
When a sheet is attached to the front side a first portion covers a part of the unique data element and a second portion covers something else.
When said sheet is attached to the back side, the second portion covers a similar part of the unique data element on the back side and the first portion covers another part of the back side of the identity document.
In an alternative embodiment, the identity document data protection tool comprises one piece sheet with a front side cover sheet section and a back side cover sheet section.
The non-stick liner comprises a first removable part to which the front side cover sheet section is attached and a second removable part to which the back side cover sheet section is attached. Between the front side cover sheet section and back side cover sheet section the one piece sheet comprise a folding structure. The folding structure can be a line printed on the sheet, a folding line and any other structure to facilitate the folding of the one piece sheet around an edge of the identity document. When attaching the one piece sheet to an identity document, first the first removable part is removed from the one piece sheet. Then the front side cover sheet section is attached to the front side of the identity document. Subsequently, the second removable part of the liner is removed and the back side cover sheet section is folded around the edge of the identity document and attached to the back side of the identity document.
Fig. 3 schematically shows a passport with a page forming a data protection sheet integrated in it. Said page has similar data protection features as the embodiments of a data protection sheet described above. When opening the passport, the page forming the data protection sheet remains attached to the page with the unique visible data elements. Only, when one has to make a copy of the whole page with unique visible data elements, he has to release the page forming the data protection sheet from the page with the unique data elements. When the passport is closed, the data protection sheet will be pressed back against the page with the visible unique data elements so that they will stay together again when the passport is opened again.
A specific type of identity document may be protected against copying by means of the following actions: - providing an identity document data protection tool described before; - removing the data protection sheet from the non-stick liner; and - attaching the data protection sheet to the identity document such that a main part of the at least one unique visible data element can be captured by an image capturing device and a remaining part of the at least one unique visible data element cannot be captured by the image capturing device. If the identity document is in the form of a booklet with several pages, the method comprises further: - removing the instruction sheet from the non-stick liner; and
- attaching the instruction sheet to the page in the booklet opposite the page to which the data protection sheet is attached.
It should be noted that in case the data protection sheet does not have an adhesive layer or is not static, the data protection sheet may be attached to the identity document by means of adhesive tape or stickers.
It should be noted, that the data protection sheet may comprise one or more openings. In this way some parts of the identity document are not covered by the data protection sheet. Furthermore, it is not necessary that an adhesive layer used to attach the data protection sheet to the identity document covers completely the data protection sheet. An adhesive layer along the periphery of the sheet may be sufficient.
While the invention has been described in terms of several embodiments, it is contemplated that alternatives, modifications, permutations and equivalents thereof will become apparent to those skilled in the art upon reading the specification and upon study of the drawings. The invention is not limited to the illustrated embodiments. Changes can be made without departing from the scope of the appended claims.
