Multilayer Security Seal
The present invention relates to a multilayer security seal comprising a carrier and an adhesive layer arranged on the entire area underneath the carrier, the following layers being arranged between carrier and adhesive layer in any case: a) a first layer—marking layer—not applied to the entire area, b) a second layer—contrast layer—applied to the entire area. It is proposed that an individual identifier, which is at least partly provided in the composite, be contained for the purpose of verification.
1 . Multilayer security seal comprising a carrier and an adhesive layer arranged on the entire area underneath the carrier,
the following layers being arranged between carrier and adhesive layer in any case:
a) a first layer—marking layer—not applied to the entire area
b) a second layer—contrast layer—applied to the entire area
wherein an individual identifier is contained for the purpose of verification.
2 . Multilayer security seal according to claim 1 , wherein the individual identifier for the purpose of verification can at least partly be detected as exposed and is at least partly configured so as to be hidden.
3 . Multilayer security seal according to claim 2 , wherein the exposed part of the individual identifier is arranged above the carrier and the hidden part of the identifier is arranged underneath the carrier.
4 . Multilayer security seal according to claim 2 , wherein the hidden part of the identifier and the exposed part of the identifier are correlated with each other.
5 . Multilayer security seal according to claim 4 , wherein at least part of the exposed identifier is identical to at least part of the hidden identifier and/or wherein at least part of the hidden identifier supplements, in particular completes, at least part of the exposed identifier.
6 . Multilayer security seal according to claim 1 , wherein the individual identifier is machine-readable.
7 . Multilayer security seal according to claim 1 , wherein the marking layer is arranged above the contrast layer.
8 . Multilayer security seal according to claim 1 wherein the marking layer contains a fluorescent dye.
9 . Multilayer security seal according to claim 1 , wherein the marking layer contains an additional identifier and/or the hidden part of the individual identifier.
10 . Multilayer security seal according to claim 1 , wherein the individual identifier and/or the additional identifier are formed and arranged in such a way that they are not visible without aids and/or with the naked eye.
11 . Multilayer security seal according to claim 1 , wherein the identifier can be read only by machine.
12 . Multilayer security seal according to claim 1 , wherein in any case part of the identifier is encoded.
13 . Multilayer security seal according to claim 1 , wherein the identifier has a 1-dimensional bar code or a 2-dimensional matrix code.
14 . Multilayer security seal according to claim 1 , wherein the identifier has a hologram, in particular a computer-generated hologram.
15 . Multilayer security seal according to claim 1 , wherein it is formed as a security label.
16 . Multilayer security seal according to claim 1 , wherein it is formed as an adhesive tape.
17 . Multilayer security seal according to claim 14 , wherein the adhesive tape has a plurality of individual identifiers, preferably at regular intervals.
18 . Method for the verification of the intactness of a pack, comprising the steps of
securing a pack with a multilayer security seal formed in accordance with claim 1 ,
inspecting the intactness of the security seal, verfifying the security seal with respect to its authenticity.
19 . Method according to claim 18 , further comprising the step of reading and verfifying the individual identifier.
20 . Method according to claim 19 , further comprising the step of decrypting the individual identifier and/or comparing the individual identifier with a reference value for verification.
21 . Method according to claim 20 , further comprising the step of reading the reference value from the security seal.
22 . Method according to one of claims 18 , further comprising the step of reading an identifier from the marking layer.
23 . Method according to one of claims 18 , further comprising the step of
checking the intactness of the security seal, opening the security seal and
checking a hidden part of the individual identifier for a valid correlation with an exposed part of the identifier, wherein the steps are performed in the stated sequence.
24 . Method according to claim 23 , wherein the complete identifier is verified by means of comparison with a database.
25 . Method according to one of claims 18 , wherein the verification of the security seal is carried out automatically.
26 . Method according to one of claims 25 , wherein the automatic verification of the security seal is carried out such that when an in authentic security seal is present, a signal is given and/or the affected pack is sorted out.
