Abstract

The invention provides a method, system, and program product for encrypting portions of a document using selective annotation. One method according to the invention includes: defining an annotation border adjacent a portion of a document using a digital pen; applying to the portion of the document an annotation verb specifying that the portion of the document is to be encrypted; entering into the portion of the document information to be encrypted; and encrypting the portion of the document.

Claims

1. A method for encrypting a portion of a document written with a digital pen, the method comprising:

defining an annotation border adjacent a portion of a document using a digital pen;

applying to the portion of the document an annotation verb, wherein the annotation verb specifies whether the portion of the document is to be encrypted; and

in the case that the annotation verb specifies that the portion of the document is to be encrypted, encrypting the portion of the document.

2. The method of claim 1, wherein applying includes entering the annotation verb using the digital pen.

3. The method of claim 1, wherein the annotation verb specifies that the portion of the document is to be encrypted for at least one of the following:

an individual and a group of individuals.

4. The method of claim 3, wherein applying includes selecting a public key of the individual or group of individuals stored in the digital pen.

5. The method of claim 1, wherein the annotation verb includes a password.

6. The method of claim 1, wherein the portion of the document includes information to be encrypted.

7. The method of claim 1, wherein encrypting the portion of the document is performed using the digital pen.

8. The method of claim 1, further comprising:

entering into the portion of the document information to be encrypted.

9. The method of claim 1, further comprising:

defining an additional annotation border adjacent an additional portion of the document using the digital pen;

applying to the additional portion of the document an additional annotation verb, wherein the additional annotation verb specifies whether the additional portion of the document is to be encrypted; and

in the case that the additional annotation verb specifies that the additional portion of the document is to be encrypted, encrypting the additional portion of the document,

wherein;

the annotation verb specifies that the portion of the document is to be encrypted for at least one of the following;

an individual and a group of individuals;

the additional annotation verb specifies that the additional portion of the document is to be encrypted for at least one of the following;

an individual and a group of individuals; and

the individual and/or group of individuals for whom the portion of the document is to be encrypted is different than the individual and/or group of individuals for whom the additional portion of the document is to be encrypted.

10. A system for encrypting a portion of a document written with a digital pen, the system comprising:

a system for defining an annotation border adjacent a portion of a document using a digital pen;

a system for applying to the portion of the document an annotation verb, wherein the annotation verb specifies whether the portion of the document is to be encrypted; and

a system for encrypting the portion of the document.

11. The system of claim 10, wherein the system for applying includes a system for entering the annotation verb using the digital pen.

12. The system of claim 10, wherein the annotation verb specifies that the portion of the document is to be encrypted for at least one of the following:

an individual and a group of individuals.

13. The system of claim 12, wherein the system for applying includes a system for selecting a public key of the individual or group of individuals stored in the digital pen.

14. The system of claim 10, wherein the annotation verb includes a password.

15. The system of claim 10, further comprising:

a system for entering into the portion of the document information to be encrypted.

16. A program product stored on a computer-readable medium, which when executed, encrypts a portion of a document written with a digital pen, the program product comprising:

program code for defining an annotation border adjacent a portion of a document using a digital pen;

program code for applying to the portion of the document an annotation verb, wherein the annotation verb specifies whether the portion of the document is to be encrypted; and

program code for encrypting the portion of the document.

17. The program product of claim 16, wherein the program code for applying includes program code for entering the annotation verb using the digital pen.

18. The program product of claim 16, wherein the annotation verb specifies that the portion of the document is to be encrypted for at least one of the following:

an individual and a group of individuals.

19. The program product of claim 18, wherein the program code for applying includes program code for selecting a public key of the individual or group of individuals stored in the digital pen.

20. The program product of claim 16, wherein the annotation verb includes a password.

21. A method for deploying an application for encrypting a portion of a document written with a digital pen, comprising:

providing a computer infrastructure being operable to;

define an annotation border adjacent a portion of a document using a digital pen;

apply to the portion of the document an annotation verb, wherein the annotation verb specifies whether the portion of the document is to be encrypted; and

encrypt the portion of the document.
