Abstract

Abstract A secure document is produced by securely attaching to a support a body of including a security feature and having a shape which conveys information to the eye. For example the body is a layer of magnetizable material having apertures of letters, numbers and the like. The document can be examined by both magnetic and optical examination apparatus to cross-check that no alteration has been made. A method of making a secure document and examination apparatus is also described. The security feature may be a pattern of magnetic anisotropy fixed into the material.

Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 106 words
A method of applying security material to a support in a form which represents information including providing a source of selectively releasable security material having a security feature of a detectable pattern of a magnetic material property, applying a data recording element to the security material source to release material from the source in the form of said element, securely bonding at least one of the released material form and the matching remaining material form in the source to a respective support, thereby to produce a secure document having data securely represented by the material form on the support, the material itself including said security feature.
Claim 2
Independent Claim 106 words
A method of applying security material to a support in a form which represents information including providing a source of selectively releasable security material having a security feature of a detectable pattern of a magnetic material property, applying a data recording element to the security material source to release material from the source in the form of said element, securely bonding at least one of the released material form and the matching remaining material form in the source to a respective support, thereby to produce a secure document having data securely represented by the material form on the support, the material itself including said security feature.
Claim 3
Dependent Claim 26 words
A method according to claim 1 including bonding the released form to a checking document support and bonding the remaining material to a secure document support.
Claim 4
Dependent Claim 23 words
A method according to claim 1 including applying heat with the application of the data recording element to release material from the source.
Claim 5
Dependent Claim 14 words
A method according to claim 3 including applying heat from the data recording element.
Claim 6
Dependent Claim 13 words
A method according to claim 4 including bonding the form by hot blocking.
Claim 7
Dependent Claim 22 words
A method according to claim 1 including making a magnetic recording with the data recording element when releasing material from the source.
Claim 8
Dependent Claim 61 words
A method according to claim 1 including providing said source as a layer of magnetisable material having magnetically anisotropic particles in a set binder on a carrier the easy axis of magnetisation of the particles being aligned in selected areas of the layer in a distinct selected direction, the selected directions forming a remanence variation pattern which is the security feature.
Claim 9
Dependent Claim 38 words
A method according to claim 1 including providing a plurality of data recording element forms representing a group of distinct shapes the group including at least one of alphanumeric shapes, arbitrary data shapes, character shapes and graphic shapes.
Claim 10
Dependent Claim 72 words
A secure document including a layer of magnetisable material having a security feature, the layer of magnetisable material having at least one aperture of alpha-numeric character form representing information securely recorded on the document, the magnetisable material layer security feature including a detectable pattern of a magnestisable material property fixed in the layer, and the character form being both eye visible and magnetically detectable as a check against alteration of the information.
Claim 11
Dependent Claim 72 words
A secure document including a layer of magnetisable material having a security feature, the layer of magnetisable material having at least one aperture of alpha-numeric character form representing information securely recorded on the document, the magnetisable material layer security feature including a detectable pattern of a magnestisable material property fixed in the layer, and the character form being both eye visible and magnetically detectable as a check against alteration of the information.
Claim 12
Dependent Claim 18 words

Claim 13
Dependent Claim 77 words
A secure document recording apparatus including means to transport a support material and a security material source through the apparatus to a recording location, means to apply a distinct shape to the security material source at said location, means to heat the source in the region of said shape and release, transfer and attach material from the source to the support in said shape and means to transport the support and attached material shape from said location.
Claim 14
Dependent Claim 77 words
A secure document recording apparatus including means to transport a support material and a security material source through the apparatus to a recording location, means to apply a distinct shape to the security material source at said location, means to heat the source in the region of said shape and release, transfer and attach material from the source to the support in said shape and means to transport the support and attached material shape from said location.
