Abstract

There is provided an information processing device including a first program execution unit that loads, interprets, and executes code of a computer program created by a procedural language. The program execution unit includes at least one port, and via this port, executes a second computer program created by a procedural language executed by a second program execution unit after authenticating with the second program execution unit.

First claim

The invention claimed is:

1. An information processing device to safely link separate, independently executed, sequential execution data processing modules, said information processing device comprising:
a hardware controller configured to have installed therein a first program execution unit to load, interpret, and execute code of a computer program created by a procedural language, wherein the first program execution unit includes a port, and is configured to execute, by way of the port, a second computer program created by a procedural language installed in a second program execution unit after authenticating with the second program execution unit,
wherein the first program execution unit is further configured to execute code of a third computer program installed in a third program execution unit without being authenticated with the third program execution unit when (i) the first program execution unit is mutually authenticated with the second program execution unit and (ii) the second program execution unit is mutually authenticated with the third program execution unit, and
wherein the first program execution unit includes a plurality of authentication modes that differ depending on whether the information processing device is (i) in a first connection state in which the information processing device is able to execute according to an instruction from the information processing device itself or (ii) in a second connection state in which the information processing device is being instructed to execute via the port from another device, and wherein the first program execution unit is configured to execute a variable or function defined by a computer program after successful authentication in an appropriate one of the authentication modes.

2. The information processing device according to claim 1 , wherein the first program execution unit authenticates through the port with the second program execution unit provided in another device.

3. The information processing device according to claim 1 , wherein the computer program executed by the first program execution unit is a program of an electronic money system.

4. An information processing method for use in an information processing device having a hardware controller and configured to safely link separate, independently executed, sequential execution data processing modules, said information processing device, said method comprising:
loading, interpreting, and executing code of a computer program created by a procedural language, by a first program execution unit that includes a port, said first program execution unit being installed in the controller, wherein the executing executes, via the port and by the first program execution unit, a second computer program created by a procedural language installed in a second program execution unit after authenticating with the second program execution unit; and
executing code, by the first program execution unit, of a third computer program installed in a third program execution unit without being authenticated with the third program execution unit when (i) the first program execution unit is mutually authenticated with the second program execution unit and (ii) the second program execution unit is mutually authenticated with the third program execution unit, and
wherein the first program execution unit includes a plurality of authentication modes that differ depending on whether the information processing device is (i) in a first connection state in which the information processing device is able to execute according to an instruction from the information processing device itself or (ii) in a second connection state in which the information processing device is being instructed to execute via the port from another device, and
said method further comprising
executing a variable or function defined by a computer program after successful authentication in an appropriate one of the authentication modes.

5. A non-transitory computer readable medium having stored thereon a computer program which when executed causes an information processing method to be performed by an information processing device having a hardware controller and configured to safely link separate, independently executed, sequential execution data processing modules, said information processing device, said method comprising:
loading, interpreting, and executing code of a computer program created by a procedural language, by a first program execution unit that includes a port, said first program execution unit being installed in the controller, wherein the executing executes, via the port and by the first program execution unit, a second computer program created by a procedural language installed in a second program execution unit after authenticating with the second program execution unit, and
executing code, by the first program execution unit, of a third computer program installed in a third program execution unit without being authenticated with the third program execution unit when (i) the first program execution unit is mutually authenticated with the second program execution unit and (ii) the second program execution unit is mutually authenticated with the third program execution unit, and
wherein the first program execution unit includes a plurality of authentication modes that differ depending on whether the information processing device is (i) in a first connection state in which the information processing device is able to execute according to an instruction from the information processing device itself or (ii) in a second connection state in which the information processing device is being instructed to execute via the port from another device, and
said method further comprising
executing a variable or function defined by a computer program after successful authentication in an appropriate one of the authentication modes.
