APPARATUS, AND ASSOCIATED METHOD, FOR PROVIDING SECURE DATA ENTRY OF CONFIDENTIAL INFORMATION
A hardware token, and an associated methodology, that converts confidential input information into secure form prior to its input to a computing station, such as a desktop or laptop computer. The hardware token is positioned in line between an input keyboard or keypad and the computer. All confidential information is converted into secure form, such as by encryption by an encryption key retrieved from a memory location of the hardware token.
1 . Apparatus for facilitating entry of confidential information at a secured-communication-service station, said apparatus comprising:
a connector configured to form a connection with an input location of the secured communication service station;
a confidential information store configured to store confidential information; and
a converter configured to form secure data using the confidential information stored at said confidential information store, the secure data, once formed, provided to the secure communication service station by way of said connector.
2 . The apparatus of claim 1 wherein said connector is configured to form a connection with an input port of a computer.
3 . The apparatus of claim 2 wherein said connector is configured to form a connection with a USB, Universal Serial bus, port of the computer.
4 . The apparatus of claim 2 wherein said connector is configured to form a connection with a serial port of the computer.
5 . The apparatus of claim 1 wherein the confidential information stored at said confidential information store comprises an encryption key.
6 . The apparatus of claim 1 wherein said converter is configured to combine input information with the confidential information to form the secure data.
7 . The apparatus of claim 6 wherein said converter is configured to encrypt input information to form the secure data.
8 . The apparatus of claim 1 wherein the confidential information store is configured to store a first encryption key and at least a second encryption key.
9 . The apparatus of claim 8 wherein said converter is configured to form first encrypted data using the first encryption key and to form second encrypted data using the second encryption key.
10 . The apparatus of claim 1 further comprising an input actuator configured to form input information responsive to input activation thereof.
11 . The apparatus of claim 1 wherein the secured communication service station comprises a portable computer having an external keyboard and wherein said connector is configured to form a connection with a keyboard input port of the portable computer.
12 . The apparatus of claim 11 wherein said converter is adapted to receive input information formed by actuation of the external keyboard and wherein said converter is configured to combine the confidential information with the input information to form the secure data.
13 . A method for facilitating entry of confidential information at a secured-communication-service station, said method comprising:
storing confidential information external to the secured-communication-service station;
forming secure data external to the secured-communication-service station using the confidential information; and
providing the secure data to the secure-communication-service station.
14 . The method of claim 13 further comprising generating input information external to the secured-communication-service station.
15 . The method of claim 14 wherein said forming comprises combining the input information and the confidential information.
16 . The method of claim 13 wherein said storing the confidential information comprises storing a first encryption key and at least a second encryption key.
17 . The method of claim 16 wherein said forming the secure data further comprises selecting whether to form first secure data using the first encryption key and selecting whether to form second secure data using the second encryption key.
18 . The method of claim 13 further comprising using the secure data provided to the secure-communication-service station pursuant to a secure communication service.
19 . A method for facilitating secured data entry at a personal computer, said method comprising:
positioning an external hardware token in line between an input key and the personal computer;
encrypting input information input by way of the input key to the external hardware token from encrypted information; and
providing the encrypted information to the personal computer.
20 . The method of claim 19 wherein said positioning comprises hot plugging the external hardware in line between the input key and the personal computer during operation of the personal computer.
