Secure property document and system
First Claim
1. A secure property for an article in a group of authentic articles for preventing certain alterations or duplication of the article, said secure property comprising:
- at least two sets of data carried by said article, each said data set containing at least one data element which has a spacial relationship to at least one data element of the other data set,one of said data sets containing informational data to be rendered secure by said secure property and being substantially different than the data of said other data set,said spacial relationship between said data set elements being substantially unique to said article within said group of authentic articles whereby the authenticity of said article may be determined,one of said data sets comprising means including a plurality of radiant energy modifying elements for providing data in the form of detectable radiant energy signals in response to irradiation with radiant energy of appropriate characteristics, the other of said data sets comprising magnetic data including a plurality of magnetic flux changes at least some of which are randomly spaced within limits from at least some of said radiant energy modifying elements.

Abstract
A secure property document and system are provided which prevents the use of fraudulent credit cards and other documents. The documents each include optical and magnetic data sets. Each data set contains data elements having a spacial relationship to at least some of the data elements contained in the other data set. The system reads and processes the data to determine whether or not the spacial relationship corresponds to that recorded for the particular document. If the spacial relationship codes do not agree within predetermined limits, the document is rejected by the system, whereby the transaction may be refused or additional information requested from the document holder.

4. A secure property for an article in a group of authentic articles for preventing certain alterations or duplication of the article, said secure property comprising:
-
at least two sets of data carried by said article, each said data set containing at least one data element which has a special relationship to at least one data element of the other data set, one of said data sets containing informational data to be rendered secure by said secure property and being substantially different than the data of said other data set, said spacial relationship between said data set elements being substantially unique to said article within said group of authentic articles whereby the authenticity of said article may be determined, said article carrying data representative of said spacial relationship. - View Dependent Claims (6, 7)

8. A security system for determining the authenticity of a presented document of a group of documents containing authentic documents each having at least two sets of data, each said data set containing at least one data element which is spacially related to at least one data element of the other data set, one of said data sets containing informational data to be rendered secure, said system comprising:
-
means for storing for each authentic document data indicative of the special relation of its data elements, means for sensing at least some of the data associated with each of said data sets of the presented document, means for providing signals related to said sensed data and indicative of the spacial relation of said presented document data elements, and means for effectively comparing said stored spacial relation data for the presented document, if authentic, with said signals, whereby a match within predetermined limits indicates that the presented document is in fact authentic. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A secure property for an article to prevent certain alterations or duplication of the article, said secure property comprising:
-
at least two sets of data carried by the article, each said data set containing data elements having a spacial relation to data elements of the other data set, said spacial relation being peculiar to the article, one of said data sets comprising a plurality of radiant energy modifying elements for providing data in the form of detectable radiant energy signals in response to irradiation with radiant energy of predetermined characteristics, the other of said data sets comprising magnetic data elements comprising a plurality of flux changes, said magnetic data elements occupying a predetermined area of the article, at least a portion of said radiant energy modifying elements being disposed such that at least a portion of one said data set is superimposed over the other within said predetermined area. - View Dependent Claims (19, 20, 21)
