Abstract

The document has a machine readable safety unit that contains an individual hologram (18) characterizing a document holder. The individual hologram is designed as a volume hologram in which an image (19) of the document holder as well as a coded personal oriented data or document oriented data are stored. The data is also stored in another place that is outside of the hologram in the document.

Description

The The invention relates to a security document with a machine-readable Security element that is a document owner characterizing Individual hologram contains according to the characteristics of claim 1.

Security documents like identity cards, passports, identity cards etc.. contain a variety of security features that make counterfeiting difficult should. This includes For example, holograms that are under reconstruction with certain lighting and under appropriate viewing angle pictures, symbols or also play alphanumeric information as well as kinematic information Movement structures resulting from tilting movement of the ID card in the Motive, re change their position or their chiaroscuro distribution. Other Security features are microfonts, security prints with multicolor Guilloche, so protective patterns of fine, intertwined Lines, as well as watermarks, laser prints u.v.a.

Also known is ( DE 198 12 826 C1 ; US Pat. No. 6,345,104 B1 ) authentication of images by information encoded in the image. It is superimposed on specific pixels according to a predetermined algorithm, without the visual overall impression being visibly impaired. This method is also called digital watermark or steganography. With it, for example, secret messages can be conveyed through images, proof of authorship and the forgery-proofing of documents can be increased. Compared with cryptographic methods in which the message is merely encrypted, the advantage of steganographic methods is that beyond the secret content, the existence of a message already remains hidden.

Known is also, for example, from German identity cards or passports, a individual holographic portrait stored in the card. The Hologram is on a laminated the ID card, transparent Plastic film recorded and gives the photograph of the document holder next to other motifs in holographic reconstruction again. The badges also contain Machine-readable lines with personal data, which in addition also stored holographically.

With The invention is intended to protect against counterfeiting be further increased by security documents.

According to the invention the security document has a machine-readable security element, this is an individual hologram characterizing the document owner contains. In this individual hologram, designed as a volume hologram is an image of the document holder as well as in it steganografisch encrypted personal and / or document-related data stored that also at least one further point outside the hologram in the security document are included. This results in an increased security, because the different Information fields on the card are even more closely linked and virtually undetectable where the information is actually filed is.

Preferably is the individual hologram on a first page of the security document, in particular on the back side an identity card, while the other place where the personal data on the card appear on another page of the security document, in particular on the front of the identity card located.

If the personal data of the document holder as a hash value encrypted in holgraphic reconstructed image of the document holder, results through the extra encoding a higher one Security_level.

Prefers the personal data are additionally in an electronic contain readable chip attached to the security document, over it the hologram both with the portrait of the document holder as also with his personal Data inseparably linked is. It is particularly advantageous if the stored in the hologram Data contains a machine-readable key, with which the Reading the chip is releasable. The reconstruction of the hologram provides the portrait of the document holder in which his personal Data and a key are hidden, which is detected by machine and then the chip to read out. The identity document is thus self-verifying and at the same time protects the chip against misreading.

Further Features and advantages of the invention will become apparent from the following Description of an embodiment.

It demonstrate

1 : The front of a erfindungsge according to the security document

2 : The back of the security document

In 1 is the front of a security document according to the invention 1 shown. On this are located in the usual way markings of any kind 2 and from which country 3 the security document is. In the case shown, it is therefore an identity card. In other fields are the document number 4 and the validity period 5 specified. Besides, name 6 , Gender 7 and date of birth 8th noted. A photograph 9 shows the owner of the security document whose signature 10 is also reproduced. In an electronically readable chip 11 are also the same and / or other personal data included. If individual security elements do not match, the document can quickly be recognized as fake.

The protection also serves the other field 12 which, for example, can be designed as a fake variable laser image or tilt image only with great effort. The security considerations are thus not only aimed at making the individual security elements difficult to imitate, but also that they are mutually linked and thus can not be individually forged, exchanged or reused.

This purpose is also served by a holographic portrait, located at the back of the security document 1 located in 2 is shown. On the carrier material of the security document 1 are in the illustrated embodiment, other personal information such as address 13 , Eye color 14 and size 15 imprinted, as well as the issuing authority 16 and machine readable lines 17 in which the personal data are also repeated. A hologram foil 18 is laminated to the wearer so that it can not be separated from it non-destructively. It has a sufficient thickness to store a plurality of Bragg planes and thus volume holograms. In reconstruction, the portrait appears under a suitable illumination and viewing angle 19 the document holder, in which a machine readable code is embedded, in which personal data of the owner of the security document are encrypted. After verification, the code serves as the key to unlock the electronically readable chips provided on the front of the identity card 11 ,

With The present invention thus new, additional options for securing identity cards and the like against counterfeiting created. In particular, the machine verification becomes document authenticity and the match between document data and document and the data connection the various pages of a badge further improved. In the hologram picture can about that addition, additional information, such as the hotline number in encrypted Embedded form, the hologram superimposed Storage of frequency and / or location modulated data for optical Structure allows. The integration of the features can during the exposure process of the hologram parallel to the image exposure.
