Abstract: A method of creating a signature for an article can be provided. The method can comprise illuminating regions of the article sequentially by light at non-normal incidence and detecting light reflected from the surface of each region of the article. The method can further comprise processing signals representative of the reflected light from each region, the signals being indicative of a surface roughness of the region, to determine a signature for the article.

Abstract: An apparatus may be provided for determining a signature from an article in a reading volume of the apparatus. The apparatus can comprise a source operable to generate a coherent beam and a beam directing member operable to direct the coherent beam into the reading volume. The apparatus may also comprise a detector arrangement for collecting signals created by scatter of the coherent beam within the reading volume, wherein different ones of the signals relate to scatter from different parts of the reading volume, the detector arrangement having a numerical aperture greater than a predetermined minimum and a processor operable to determine a signature for an article in the reading volume from the collected signals. Use of such apparatus can be repeated whenever required to test authenticity of the article.

Abstract: Packaged integrated circuits (ICs) of some types, such as processors, are graded and sold according to a performance scale, such as maximum specified clock speed, set by the manufacturer as a result of testing. As a record of this grading some part of the package, usually the upper surface, is marked with the specified performance attribute. However, criminal activity has developed where the packaging is relabelled to show a higher specification so the ICs can be fraudulently resold at a higher price. To address this problem, the invention envisages that manufacturers maintaining a product database for each packaged IC which logs not only the performance specification, but also a digital signature derived from a speckle pattern obtained from the packaging. Subsequently, any packaged IC can be rescanned to interrogate its speckle pattern and recompute the signature. The signature is then used to find the product in the database, whereby the originally specified performance attribute is retrieved.

Thereby the key can be transmitted via a non-secure channel to a recipient for use thereby, without it being possible for a third party to obtain a copy of the key by monitoring the channel.

Abstract: A method for authenticity verification. The method can comprise conducting a transaction between first and second parties, the parties being respectively located at first and second locations remote one-another, the outcome of the transaction being the transfer of title to goods and/or services from the first party to the second party. Data describing a value entitlement token of the second party can be captured to create a signature for the value entitlement token, the signature being based upon an intrinsic property of the value entitlement token. The signature can be transmitted from the second party to a third party which can compare the signature to a database of stored signatures. A validation result indicating whether the value entitlement token corresponds to a value entitlement token signature in the database can be transmitted from the third party to the first party.

Abstract: An article verification system can comprise a first scanner operable to scan an article to create a signature based upon an intrinsic characteristic of the article and a comparator operable to compare the created signature to a plurality of stored signatures created from previous scans of a plurality of articles. More than one stored signature can be associated with each article, each signature for each article being associated with a respective different portion of each article to the other signatures for that article. Thus the system provides for an article to be checked against multiple records of that article. In some examples, a single match between the later scan and a stored record can be used to positively verify the article.

Abstract: An article identification method can comprise: determining a signature from an article based upon an intrinsic characteristic of the article; and comparing the determined signature to a stored signature. The method can also comprise splitting the determined signature into blocks of contiguous data, performing a comparison operation between each block and respective blocks of the stored signature, and comparing an attribute of a comparison result from each block comparison to an expected attribute of the block comparison to determine a compensation value for use in determining a comparison result. The method can also comprise determining a similarity result between the determined signature and the stored signature, using the compensation value to adjust the determined signature. Thus an article damaged by stretching or shrinking can be successfully identified. Also, a non-linear signature determination can be accommodated without losing identification accuracy.

Abstract: The invention relates to a system 100 for verifying the authenticity of medicament entitlement tokens, such as prescriptions 102, used to control the dispensing of medicaments. The system comprises a network 104 connecting at least one token provider terminal 106, a system server 120 and a verification terminal 130. The token provider terminal 106 is operable to provide a signature from a speckle pattern derived from a medicament entitlement token that can be stored by the server system 120. The verification terminal 130 can then be operated remotely to recreate the signature in order to verify the authenticity of the medicament entitlement token by comparing it to stored signatures. The system 100 relies upon the intrinsic physical properties of the medicament entitlement token to generate a unique signature for each token that is produced. This makes the medicament entitlement tokens themselves very difficult to forge.

Abstract: A data access system can be provided. The system can comprise a data record associated with a stored access token signature and a signature generator, operable to scan an access token to create a signature for the access token, the signature being based upon an intrinsic property of the access token. The system can also comprise a comparator for comparing the created signature with the stored signature. The system can be operable to make the data record available in the event of a match between the stored signature and the created signature. Thus secure access to sensitive or private data can be controlled using an access token in the possession of an individual or entity described by or in the data record.
