At block 2040 control circuit 210 determines if X,Y coordinate data received from touch screen 20 is included in X,Y coordinate data representing signature entry area 2008. If a user during signature entry, intentionally or unintentionally contacts with a finger or other hand part, a portion of touch screen 20 outside of area 2008 in a manner sufficient to register a data entry, touch screen 20 will likely report back to control circuit 210 a data entry coordinate point that is the average of the point of contact by the user's hand and the point of contact by stylus 74.

  • Distribution Network 370 refers to the computer systems operated by distribution service providers who receive transactional data from a retailer (e.g. from a computer system, a POS terminal such as terminal 10, a hub, a server, and a cash register) and evaluate the availability of several debit or credit card networks and route the data to one selected debit or credit card networks 320 or 322 based on an established criteria. Some transactions are processed without being routed through distribution networks and others are, normally dependent on the selection made by a retailer. [0170] In a further aspect of POS Network 300,
  • POS Network 300 can be in communication with another computer Network 380, which may be the Internet (World Wide Web) . Connecting POS Network 300 to another Network 380 allows POS Network 300 to readily access information from a wide variety of computer databases, which information is pertinent to financial transactions. For example, by way of communication with Network 380, POS Network 380 can access such information as drive, license identification information, consumer credit rating information, consumer criminal record information, sales history information, consumer demographic data, and other consumer information. Aspects of the invention relating to access of information from Network 380 will be discussed in greater detail herein.

  • Encryption keys may be stored in other, mechanically and logically secure, preferably erasable, storage locations.
  • Encryption keys which terminal 10 may use for PIN encryption typically comprise one of two types: "master session” and DUKPT .
  • Master session keys are used by a symmetrical encryption algorithm.
  • the Data Encryption Standard (DES) is the most common form of master session keys.
  • terminal 10 has a strong "master” key and a second "session” key. Typical implementations use a weaker session key.
  • the session key is used to encrypt PIN blocks.
  • the master key is used to secure replacement session keys. Terminal and the first computer (host) of POS Network 300 that receives and processes the encrypted PIN block must have the same key.
  • POS Network 300 comprised of many "nodes” or computer systems connected by various communications links, translates the PIN from the key used by the sending device (terminal, host, etc.) to the encryption key and scheme used by the next node in the transmission chain. This repeats until the encrypted PIN block arrives at Issuing Bank 333. Accordingly, "security zones" are created which increase the difficulty of an unscrupulous party compromising the system. It also allows each zone to trust only the devices with which it directly communicates. It also greatly simplifies distribution of the symmetric keys. A given node must only deal with two other nodes rather than every node in the chain. Debit card Issuing Bank 333 does not convert the PIN block to clear data.
  • Issuing Bank 330 submits the encrypted PIN block to a security device commonly called a Network Security Processor (NSP) .
  • NSP Network Security Processor

  • DUKPT deep ultraviolet erasure-sensitive cryptographics
  • encryption scheme is common in POS terminals and PIN pads installed since 1997.
  • the advantage of DUKPT and other similar schemes is that each PIN block encryption uses a new ("unique") key whereas the master session encryption uses the same key for all transactions.
  • the "T” in DUKPT can also mean "terminal” since the terminal ID is used to generate the key set, a given base key can create many unique key sets.
  • DUKPT PIN encryption keys are unique and no key can be computed from any other key. So if a given transaction key is compromised, no other transactions are at risk. The base key is not stored in the terminal.
  • the current method of PIN encryption using DUKPT is similar to the master session encryption method described above. Additional data is used and the key is applied to the PIN block only for the current transaction.
  • the node security zones are substantially identical to those described above with reference to the master session described above.

If contact between conductive sections of any one of the open contact washers 292 is destroyed, sensing circuit 226 generates a tamper signal. Terminal 10 may be configured so that if terminal in a powered-down mode a tamper signal generated by sensing circuit 226 operates to disconnect secure IC chip 221 from battery 225 as is indicated by switch 227.
  • Terminal 10 may also be configured so that generation of a tamper signal when terminal is in a powered-up mode (wherein secure IC chip 221 is powered by an external power source) results in an erasure instruction being generated that causes the secure (e.g. encryption information) of chip 221 to be erased.

Abstract

La présente invention se rapporte à un terminal pour transactions qui peut comporter un circuit de saisie d'informations sécurisé, un logement conçu de manière ergonomique, un mode de rétroaction pour la saisie de signatures assurant un enregistrement précis de signatures, et au moins un ensemble de modules d'imagerie accroissant les performances du terminal. Le logement conçu de manière ergonomique peut comporter une lèvre avant qui facilite la lecture de cartes, une lèvre latérale facilitant la préhension manuelle et une région surélevée entourant un écran tactile améliorant l'enregistrement des signatures. Un module d'imagerie de l'ensemble ou des ensembles de modules d'imagerie est disposé, dans un mode de réalisation, en partie arrière du logement où il se trouve facilement accessible par un caissier. Ce terminal peut être configuré de sorte qu'un module d'imagerie soit automatiquement actionné lors d'un achat nécessitant une preuve de l'âge de l'acheteur. Un tube lumineux en saillie par rapport au logement peut être disposé à l'avant d'un module d'imagerie de manière à attirer l'attention sur un module d'imagerie lorsque ce dernier est activé.
