Abstract

An information object configured for automatic authentication of information contained therein includes an information segment to be authenticated, an authenticator address corresponding to a predetermined authenticator, and a set of instructions for establishing a communications link between the information object and the predetermined authenticator using the authenticator address, transmitting an authentication request to the predetermined authenticator, and receiving a responsive communication from the predetermined authenticator for authenticating the information segment.

Claims

1. An automatically-authenticating information object embodied in a computer-readable storage medium accessible from a first computer, said automatically-authenticating information object comprising:

an information segment to be authenticated;

an authenticator address corresponding to a predetermined authenticator resident on a second computer, the predetermined authenticator comprising an application configured to perform authentication of the information segment; and

a set of instructions for automatically authenticating the information segment when an attempt is made to access said information segment, said set of instructions including instructions for establishing a communications link between said automatically-authenticating information object on said first computer and said predetermined authenticator on said second computer using said authenticator address, transmitting an authentication request from the automatically-authenticating information object to said predetermined authenticator, receiving a responsive communication from said predetermined authenticator, and permitting the information segment to be accessed if the responsive communication indicates that the information segment is authentic.

2. The automatically-authenticating information object of claim 1, wherein said authentication request comprises a unique identifier for said information segment.

3. The automatically-authenticating information object of claim 1, wherein said responsive communication from said predetermined authenticator comprises a digital signature.

4. The automatically-authenticating information object of claim 1, wherein said responsive communication from said predetermined authenticator comprises an update to be applied to said information segment.

5. The automatically authenticating information object of claim 1, wherein said set of instructions further comprises instructions for preventing an inauthentic information segment from being viewed.

6. The automatically-authenticating information object of claim 1, wherein said set of instructions further comprises instructions for generating a warning message if said information segment is inauthentic.

7. A method for automatically authenticating electronically-represented information, said method comprising the steps of:

including an information segment to be authenticated in an automatically-authenticating information object embodied in a computer-readable storage medium;

embedding said automatically-authenticating information object in a data file;

loading the data file on a first computer;

automatically activating said automatically-authenticating information object when said data file is opened, wherein said automatically-authenticating information object establishes a communications link to a predetermined authenticator of said information segment resident on a second computer, transmits an authentication request to said predetermined authenticator, receives a responsive communication from said predetermined authenticator, and controlling access to said information segment based upon said responsive communication, said predetermined authenticator comprising an application installed on the second computer.

8. The method of claim 7, wherein said responsive communication from said predetermined authenticator comprises a digital signature.

9. The method of claim 7, wherein said responsive communication from said predetermined authenticator comprises an update for said information segment, said method further comprising the step of applying said update to said information segment.

10. The method of claim 9, wherein said predetermined authenticator confirms that an originator of said authentication request possesses a previously authentic version of said information segment prior to transmitting said update.

11. The method of claim 7, further comprising the step of preventing an inauthentic information segment from being viewed.

12. The method of claim 7, further comprising the step of generating a warning message if said information segment is inauthentic.
