Definitions

• the inherent feature is the result of a chemical manipulation of the article or the inclusion of unique characteristics in or on the article. It also requires that the encrypted code is available on a label accompanying the article; however, the code is encrypted without applying a hash function. This flaw will allow a counterfeiter to obtain the original data that defines the uniqueness of the article and to start making modifications in order to approach the original data. By using a hash function, the counterfeiter will have no information on how to modify the article to try to make it pass the authentication. Moreover, it is not clear whether the chosen characteristics will be able to withstand the natural deterioration from the use of the articles.
• Another aspect provides an authentication process for banknotes, checks or any other security documents.
• Fig. 3 shows an example of a security document having different images from different processes and showing reference points and relative points.
• Fig. 4 is an example of a function MD for the mathematical treatment of data to obtain a message.
• Fig. 5 is an example of an authentication process of a security document.
• Fig. 6 is an algorithm for the authentication of a security document.
• the certification and authentication process is based on the variations which take place during the steps of the manufacturing process of the security documents, and particularly in the interaction of those steps.
• Some aspects are related to a system for certification and authentication of security documents.
• Some aspects also relate to a method for certification and authentication of an original document, wherein the unique characteristics of every document are identified, codified and optionally inserted in the security document itself, or stored in an external database. This method and proposed system prevents falsification of security documents.
• Certification Formal procedure by which an accredited or authorized person or agency assesses (and attests in writing by issuing a certificate) the attributes, characteristics, quality, qualification, or status of individuals or organizations, goods or services, procedures or processes, or events or situations, in accordance with established requirements or standards.
• Authentication the act of confirming the truth of an attribute of a single piece of data (datum) or entity. Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be.
• Security documents - is a document that states in writing some guaranty (of each of the Guarantors), and was produced using a security printing processes and may also include security features.
• Metric function - A metric on a set X is a function (called the distance function or simply distance)
• unique characteristics is in use for all those natural variations of the document that arise in the manufacturing process and that are measurable; in particular, those provided by the security printing process for the fabrication of a security document.
• An example of a unique characteristic is the register.
• a method for digitally certifying security documents using security features and unique characteristics which are already present in mentioned document.
• the document will be digitalized, which can be done through a scanner or digital photography using different sources and kinds of illumination, as well as any other measurement of physical, chemical, or physicochemical properties of the document from which the unique characteristics can be obtained.
• the register can be measured.
• a message is constructed using some features as well as the mathematical correlation between them. According to aspects of the present disclosure, a metric function, which is a function of a distance between two points, is used.
• step 1 1a Providing suitable supplies (step 1 1a) which include the substrate, inks, security features such as watermarks, threads, transparent windows, colored fibers, foils or patches, etc.
• Fig. 1 discloses the certification process according to aspects of the present disclosure
• a security document is manufactured according to the well known processes of the prior art (Step 10), including the steps of providing special supplies 1 1a, manufacturing a substrate 13a, and conducting a manufacturing process comprising a variety of steps (13a).
• a security document is represented containing images produced by a sequence of process A, B, C and E.
• reference points Al , A2, .... AN
• B l , B2, BN C I , C2, CN
• C I C I , C2, CN
• El E2, EN
• step (30) is then transformed in step 40 through the use of a Mathematical Hash function and then encrypted in step 60 to yield a unique digital certificate.
• step 40 of figure 1 the message obtained in step (30) is then transformed using a mathematical function, such as a Hash function in order to obtain a Hashed message comprising at least one chain of characters in step 50 of Fig. 1.
• a mathematical function such as a Hash function
• There are some mathematical methods to run a Hash function for example, by means of a mathematic unidirectional process or model (algorithm) delivering a chain of characters.
• the Hashed function is then encrypted in step (60) to yield an encrypted hashed message or digital certificate.
• an asymmetric encryption algorithm is used that requires a private key (70) in order to generate a digital certificate (80) in the form of an encrypted alphanumeric chain.
• the digital certificate is, in turn, stored in a database (90) that can be kept in a server placed in secure installations, and/or it can be marked/ printed (97) back to the document ( 10) in a readable manner by the same mechanism to obtain the data (20), such as a barcode, code or plain text (fi) .
• a database (90) in addition to storing the digital certificate (80), it may also be useful to associate that digital certificate in the database with other ID data information such as the serial number of the security document, a scanned copy of the document, details on the place and time of manufacture of the document, etc.
• the encrypted information is then placed as a mark or printed back in step 97 of Fig. 1.
• the digital certificate 80 and the hashed message 50 as well as the partial hashed messages and the document ID data of the security document are stored in a database 90, placed in a server available for public access.
• the digital certificate in the form of an element (fi) can optionally be inserted on the security document 10.
• the digital certificate 80 is the result of the unique and unrepeatable relationship between the variety of images and characters due to register, which are due their manufacturing processes, present in a security document.
• a hashed message must be generated according to the features of the document of the user.
• the user/authentication authority must obtain the data of the security documents (step 130) by means of any device capable of taking the required digital image, then construct a message through the use of a metric function and the document ID data (step 140), and apply a hash function ( 150) to obtain a hashed message (160) for verification.
• the hashed message for verification (160) is compared with a decrypted hashed message (260).
• the digital certificate (80, Fig. 1) to obtain the decrypted hashed message (260) needs to be retrieved in some way.
• One source of digital certificates (80, Fig. 1) for verification is the database (280), created during the certification.
• the digital certificate can be decrypted (250) by means of a public key (230), in order to obtain a decrypted hashed message (260).
• the digital certificate can be decrypted (250) by means of a public key (230) to obtain a decrypted hashed message (260) and used to perform the comparison to establish whether the hashed message for verification ( 160) is a match with the decrypted hashed message (260), which can be locally performed by the user.
• the document is then qualified as an authentic document (400 in Fig. 6).
• the hashed message for verification (160) is not a match with the corresponding decrypted hashed message (260)
• the document is considered as a high quality counterfeit (305). The incidence of such counterfeits may provide elements/ evidence for investigating criminal patterns.
• the user should first conduct a verification step 121 for the presence of the genuine raw materials and the original security manufacturing processes present in security documents, such as banknotes. If such materials and processes are not present, then the document is considered as a low quality counterfeit (122). If the expected materials and processes are in the document and are considered as genuine, then the user should conduct a step of obtaining data ( 130).
• the authentication process is performed through the use of an application for an intelligent device, such as a smart phone or tablet.
• the application guides the user to obtain an accurate image and provides the means to connect to the Authentication Authority. After the authentication by the Authentication Authority, the result of the comparison process is delivered.
• the method provides the possibility of classifying counterfeits by their manufacturing characteristics; for such purposes, equipment is needed for automatic classification and registering (ID) of counterfeits, which is in charge of registering the features of all the counterfeits arriving at the issuing institution in order to create a database with all the information extracted from counterfeits, in order to statistically link pieces to "Counterfeiters" (not necessarily a person) and detect even slight improvements. Such information is useful in investigating and pursuing counterfeiting crimes.
• ID automatic classification and registering
• the Marking/ Printing device can be an inkjet printer, a numbering machine, laser marking devices, labeling devices, etc.
