System and method for providing controlled access to a funds dispensing device from external processors
View Patent ↗Systems and methods for providing controlled access to value dispensing devices are described and in certain examples, systems including those for providing controlled access to a postage meter from multiple programs executing on an external collocated processor are described.
1. A mailing machine having an embedded processor and an embedded user interface, wherein the mailing machine is configured to allow user interface access from an external collocated processor executing a proxy server and at least one multi-purpose software application, the mailing machine comprising:
the embedded processor including memory and instructions configured to perform the following:
receiving an exclusive external postage meter capture request from a proxy server;
determining if the embedded user interface is active;
if the embedded user interface is active, returning a busy message; and
if the embedded user interface is not active, processing the meter capture to provide and acknowledge the exclusive external access to the proxy server;
determining if the exclusive external postage meter capture request requires lockout of the embedded user interface;
if the exclusive external postage meter capture request requires lockout of the embedded user interface, then locking-out the embedded user interface and transfer exclusive user interface control of the mailing machine to the proxy server, and
if the exclusive external postage meter capture request does not require lockout of the embedded user interface, then allowing simultaneous embedded user interface access and proxy server access.
2. The mailing machine of claim 1 , wherein,
the exclusive external postage meter capture request received from the proxy server originates in an application running on the external collocated processor, and further comprising:
the embedded processor including memory and instructions configured to perform the following:
authenticating the application by using at least one validation signature stored in a secure cryptographic coprocessor included in the mailing machine, and
denying the exclusive external postage meter capture request if the application is not authenticated.
3. The mailing machine of claim 1 , further comprising:
the embedded processor including memory and instructions configured to perform the following:
then determining at a second time if the exclusive external postage meter capture request requires lockout of the embedded user interface;
if the exclusive external postage meter capture request requires lockout of the embedded user interface at the second time, then locking-out the embedded user interface and transfer exclusive user interface control of the mailing machine to the proxy server, and
if the exclusive external postage meter capture request does not require lockout of the embedded user interface at the second time, then allowing simultaneous embedded user interface access and proxy server access.
4. A mailing machine having an embedded processor and an embedded user interface, wherein the mailing machine is configured to allow user interface access from an external processor, the mailing machine comprising:
the embedded processor including memory and instructions configured to perform the following:
receiving a control request from the external processor;
determining if the external processor is authentic using a cryptographic process and terminating access from the external processor if the external processor is not authentic; and
if the external processor is authentic, and if the embedded user interface is not active, granting the control request, wherein, the control request comprises providing exclusive user interface access from the external processor.
5. The mailing machine of claim 4 , wherein,
the cryptographic process utilizes public key cryptography.
