Media handling devices, particularly Automated Teller Machines (ATMs) include a variety of independent devices integrated into the ATM. The cash handling components are frequently a target by criminals, since these components have cash that the criminals want to steal out of the ATM.
The ATM includes a variety of cooperating processors for the various integrated components. Security is of utmost concern and still there are a number of vulnerable operations that expose the cash handing components to unauthorized access by criminals. Two such sensitive operations are dispensing cash/notes and depositing cash/notes both of which require user authentication to be performed on the ATM. For example, a recycler (component having cash/notes) must authenticate for deposit and dispense operations using cryptographic keys and cryptographic techniques.
However, the cryptographic techniques and keys are exposed in varying levels of degree within the components of the ATM during the authentication process by the recycler. The techniques and keys are also exposed during ATM maintenance and during remote software loading/installation at the ATM.
Furthermore, the components transport the media between one another on transport belts, which presents another opportunity for thieves to add a component or remove a component for purposes of intercepting cash.
In addition, the components are not interchangeable or expandable to work with new components that may desired. That is, the components are centrally controlled and preconfigured to work with one another, such that removing or adding components require redesign of the ATM and the software that controls the components whenever new components are added or some components are removed from the ATM.
A significant amount of resources have been directed to reducing the exposure level of the cryptographic techniques and keys within ATMs. However, the criminals are ingenious and are continually evolving to change tactics based on industry adjustments to the design and operation of the ATMs.
In various embodiments, a modular valuable media recycling device and methods for operating a modular valuable media recycling device are provided.
According to an embodiment, a modular valuable media recycling device is provided. The modular valuable media recycling device including a plurality of modules. Each module including its own Printed Circuit Board having at least one hardware processor. Each hardware processor configured to execute firmware instructions that: i) activate electromechanical components to handle valuable media being processed with a transaction through the valuable media modular recycling device, ii) validate received security message from a previous module that handled the valuable media for the transaction, and iii) generate unique security messages that are independently validated by next modules that are to handle the valuable media for the transaction.
As used herein, the phrase “valuable media” refers to media of value, such as currency, coupons, checks, negotiable instruments, value tickets, and the like. As such, the phrases and terms “media,” “valuable media,” “document,” “currency note,” and “note,” may be used synonymously and interchangeably herein.
For purposes of the discussions that follow with respect to the
As used herein a “module” is an independent electromechanical device that may or may not have its own Printed Circuit Board (PCB) with software/firmware processing capabilities (through at least one hardware processor, memory, and non-volatile storage). Therefore, one module may have its own independent PCB, while another module may be controlled through a different module's PCB. Additionally, a “module” may be used synonymously and interchangeably with the terms “component,” and “node.”
As used herein, a “security processor” is a processor that is PCI-certified, includes: encryption engines; tamper pins and secure key storage; voltage, frequency, temperature monitors and a die active shield; on-the-fly encryption/decryption, and a secure boot procedure. The processor pins are protected by an encasing Printed Circuit Board (PCB) mesh. The PCB mesh is connected to the processor's tamper responsive circuit, such that when the mesh is broken, the encryption keys are erased.
Conventionally, components of an ATM (one type of Self-Service Terminal (SST)), are centrally controlled by a host Personal Computer (PC) through a core ATM application that processes on the host PC. Any integrated modules that are relevant to note deposit and note withdrawal transactions may have processing capabilities; however, the modules do not collaborate with one another; rather, collaboration, if done at all, is achieved through the processing of the core ATM application. This means that modules can be more easily compromised, bypassed, and/or swapped out by intruders with insecure modules or missing modules, creating security concerns for notes being deposited or withdrawn from the ATM.
Furthermore and conventionally, the feeder/stackers (f/s) of the lower transport module are integrated into the media (note) cassettes, which means any security relevant to the cassettes is entirely controlled by the cassettes and tightly coupled into the cassette. Such architecture also prevents scalability of the ATM with respect to the cassettes.
There are a number of scenarios that are of concern on ATMs in terms of security, such as malicious software that implements attacks to: fool a customer into making a deposit and return the deposit to a criminal (malware cash trap), and dispense cash from the recycler module to a criminal (malware cash dispense). For malware cash trap the commands that are vulnerable include: open shutter, close shutter, count, and store. For malware cash dispense the commands that are vulnerable include stack.
Other security concerns are present when deposit/dispense modules are bypassed or swapped out with malware infected or insecure modules that permit a thief to dispense notes from the cassettes.
The system 100 for a modular recycling device described herein corrects the lack of scalability and improves on the security holes of the deposit/dispense modules in a SST over conventional approaches. This is done by changing the conventional architecture and the conventional processing associated with processing a note during a deposit or during a withdrawal through novel module message passing that includes security processing.
As will be described more completely herein, the system 100 provides a modular and scalable architecture that collectively defines an infrastructure for distributed note handling (processing), where the modules (may also be referred to as “nodes” herein) collaborate over a secure device-level (SST composite device-level) Intranet. This provides distributed command, control, security, and data functions for deposit and withdrawal note processing within the SST.
The system 100 includes a pocket infeed module 110, an escrow module 120, an upper note transport module 130, a centralizer module 140, a note validator module 150, a lower note transport module 135, a plurality of f/s modules 151-155, a plurality of cassette modules 161-165, and a plurality of exception cassette modules 170.
The transport paths that a note can take during deposit and withdrawal operations on the SST are shown and described below with respect to the
The pocket infeed module 110 includes a pocket 111 for receiving (during a deposit operation/transaction) a single note or a bunch of notes (notes represented by the circles in the FIGS. with an “M” inside the circles). Unlike a conventional pocket infeed module, the pocket infeed module 111 also includes its own f/s 112. When a bunch of notes are placed in the pocket 111, the notes are transported to the f/s 112, which then delivers each note individually to the upper transport module 130 to the centralizer 140. The f/s 112 also stacks notes during a withdrawal transaction for delivery through the pocket 111 to a consumer performing the withdrawal transactions.
In an embodiment, the pocket infeed module 110 is capable of handling a deposit of approximately 300 notes as a bunch deposit maximum and is capable of dispensing approximately 300 notes as a bunch dispense maximum.
In an embodiment, the pocket infeed module 110 includes a metal and foreign object detector at the pocket 111 infeed to prevent damage to the system 100 when non-note objects are put into the pocket 111.
It is also to be noted that although, the pocket infeed module 110 has thus far been described as receiving notes for processing, the pocket infeed module 110 is also designed to eject notes during a withdrawal transaction or when a note is rejected and not stored in one of the exception cassettes 170.
The centralizer 140 ensures that each note being processed within the system 100 is centralized on the transport path independent of the dimensions of the notes. The centralizer 140 delivers each note in the bunch to the validator 150. The validator 150 performs note identification (note denomination, note type (government backing the note, check, etc.) on received notes, and the validator 150 performs note validation processing on received notes to determine whether the notes are damaged, counterfeit, and/or authentic. The validator 150 then passes the note to the escrow 120.
The escrow 120 includes a large escrow 121 for holding/storing authenticated/validated notes on a rotating drum. The escrow also includes a temporary escrow 122 for holding/storing damaged or counterfeit notes on a separate rotating drum. The escrow 120 provides each note to the upper transport 130. The upper transport 130 sends each note along the transport path to the lower transport 135.
Conventionally, at this point, the notes would be sent by a conventional lower transport to a conventional cassette. This is not the case with the system 100, where the lower transport 135 sends the notes to the f/s 151-155 and based on the denomination of the note being handled a particular f/s (e.g., 151) feeds or stacks the note(s) into a particular note denomination-based cassette (e.g., 161) for storage.
If the note provided by the escrow 120 to the upper transport 130 is received by the lower transport 135 as a damaged or counterfeit note, the lower transport 135 directs the note to one of the exception cassettes 170 where the note is housed/stored. The exception cassettes 170 are removable modules.
The processing described above illustrated a deposit transaction. The processing for a withdrawal transaction is reversed, where a particular cassette 161 or set of cassettes 161-165 (based on the needed denominations) delivers the notes to the corresponding f/s 151-155. The note then is sent to the lower transport 135 and provided to the upper transport 130 where it is provided to the f/s 112 of pocket infeed module 110 and sent from the f/s 112 to the pocket 111 for delivery through an aperture (opening) to a customer performing the withdrawal transaction.
The pocket infeed 110, the escrow 120, the upper transport 130, the validator 150, the lower transport 135, each of the f/s 151-155, the cassettes 161-165, and the exception cassettes 170 include their own PCB (with processor, memory, and storage). Conventionally, not all of these modules including their own independent processing capabilities or hardware; rather, the modules were controlled by the PCBs of other modules or exclusively by the host PC of the SST.
Each of the above noted modules (110, 120, 130, 150, 135, 151-155, 161-165, and 170) include at least one security processor. Firmware or software is programmed on each module to send and process messages during deposit and withdrawal transactions on the SST. The firmware performs cryptographic operations on received messages to authenticate the received message. Furthermore, each module includes secure memory or storage that allows for management by the firmware of cryptographic keys, certificates, hash values, etc. The firmware can process symmetric key management, symmetric data message authentication, asymmetric Public Key Infrastructure (PKI) authentication for symmetric key distribution, etc. Each module includes its own unique identifier (e.g., serial number, part number, revision and manufacture date and time stamp) that is utilized to provide each module with a unique cryptographic key/hash value. This provides a mechanism by which each module can uniquely authenticate and verify each of the remaining modules and determine the authenticity of any received message during the deposit or withdrawal operations on the SST. Each module can also generate its own messages with its own digital signature or modify an existing message that was processed by a previous module and is being sent by a particular module to a next module.
As used further herein, the modules 110, 120, 130, 150, 135, 151-155, 161-165, and 170 are collectively referred to as the modular recycling device.
Each module of the modular recycling device processes commands, control operations, and data operations. Moreover, each module of the modular recycling device is configured to perform self-diagnostic tests on itself and perform fault management operations. Each module of the modular recycling device is configured to cryptographically create messages, modify existing messages, and validate/authenticate received messages from other ones of the modules that comprise the modular recycling device. The modules of the modular recycling device provide distributed, collaborative, cooperative, and security-based operations during transactions at the SST where notes are being deposited into or withdrawn from the cassettes 161-165.
It is to be noted that other arrangements with more or less PCBs may be used without departing from the modular recycling device embodiments presented herein. That is, the
The pocket infeed 110 includes a pocket PCB 114, a metal detector PCB 113, and the feeder stacker 112. The upper transport 130 and the bill validator 150 include an upper transport PCB 131. The escrow 120 includes an escrow PCB 123. A distribution PCB 131 interfaces/connects the PCBs of the pocket infeed 110, the upper transport 130, the validator 150, and the escrow 120.
A second distribution PCB 132 interfaces the upper distribution PCB 131 to the modules of the lower transport 135. Each f/s (151-155) includes its own modular interconnect PCB (151A-155A). Each cassette (161-165) includes a cassette PCB and a lift PCB 161A-165A. Each cassette PCB 161A-165A is connected to a modular interconnect PCB 161B-165B. A USB CAN bridge provides connections from the lower distribution PCB 132 to the escrow PCB 123.
The
Specifically,
The path of the note begins at (1) within the pocket infeed 110. The first Mess identifies whether the transaction at the SST is a deposit or a withdrawal. Assuming, the transaction is a deposit, the note is passed along the transport path (2) to the centralizer 140 where the note is centralized (centered) along the transport track. If the Mess was a withdrawal transaction, then the Mess (3) is sent from the packet infeed 110 to the lower module (135, 151-155, 161-165, and/or 170). The note received (4) for a withdrawal from the lower module (135, 151-155, 161-165, and/or 170) or a note being deposited is received by the centralizer 140 (2 or 5) and centered along the transport path. Next, the escrow module 120 sends a message to receive the note (6 and 7) from the centralizer 140. The centralizer 140 provides the note (8) to the bill validator 150. The bill validator 150 validates or invalidates the note and sends the note (9) where it is received (10) by the escrow 120. The escrow 120 then waits until all notes in a bunch being deposited are received (11) more notes are received at (12). The escrow provides notes associated with rejected notes, at (13), to the f/s 111 of the pocket infeed 100, the f/s 111 receives the rejected notes at (14) and waits (15) until all notes in a bunch associated with a rejected notes are received from the escrow 120. The f/s 111 provides notes from a bunch being deposited at 16. The lower module (135, 151-155, 161-165, and/or 170) receives notes being deposited at 17 and waits at 18 until all notes are received by the lower module (135, 151-155, 161-165, and/or 170).
Specifically,
At 1 a message is sent that a deposit for a bunch of notes is being made on the SST to the lower module (135, 151-155, 161-165, and/or 170). The notes are individually sent from the bunch maintained by the f/s 111 to the centralizer 140. The centralizer 140 provides each note from the bunch to the bill validator 150. The bill validator 150 provides to each note from the bunch to the escrow 120. At 2, the pocket infeed 110 sends a message when the last note of the bunch is processed through the f/s 111 to the escrow 120. The escrow 120 waits until receiving message 2 to process the notes from the bunch. It may be that one or more invalidated notes are sent back from the escrow 120 to the f/s 111 for ejection out the pocket infeed 110 based on validation information received from the validator 150 while the notes were processed.
The note path associated with deposits to the escrow 120 can be seen in path 1-2-8-9-10-11 in the
