Abstract

The present application provides a method for publishing work in a network, including: obtaining, by an end-user device associated with a current user, a prior work file that is not published by the current user in a network, where the prior work file includes a digital signature of a prior author and a prior work; generating, by the end-user device and based on an operation of the current user, a new work file that includes the prior work, the digital signature of the prior author, and content added based on the operation of the current user; and publishing, by the end-user device, the new work file in the network. This solution ensures the prior work cannot be used out of context, and modifications to the prior work are easy to identify, thereby improving integrity and authenticity of a work propagated on the internet.

Claims

1. A computer-implemented method for publishing work in a network, the method comprising:

obtaining, by an end-user device associated with a current user, a prior work file that is not published by the current user in a network, wherein the prior work file comprises a digital signature of a prior author and a prior work;

generating, by the end-user device and based on an operation of the current user, a new work file that comprises the prior work, the digital signature of the prior author, and content added based on the operation of the current user; and

publishing, by the end-user device, the new work file in the network.

2. The computer-implemented method of claim 1, wherein the prior work in the prior work file is encrypted using a private encryption key of the prior author.

3. The computer-implemented method of claim 1, wherein the prior work and the content added based on the operation of the current user in the new work file are encrypted using a private encryption key of the current user.

4. The computer-implemented method of claim 1, wherein the new work file further comprises a digital signature of the current user.

5. The computer-implemented method of claim 4, wherein the digital signature of the current user comprises a digital signature appended, using a private signature key of the current user, to the content added based on the operation of the current user.

6. The computer-implemented method of claim 5, wherein the digital signature is further appended to the prior work.

7. The computer-implemented method of claim 1, wherein generating, by the end-user device and based on an operation of the current user, a new work file that comprises the prior work comprises:

performing signature verification on the prior work using the digital signature of the prior author;

determining whether signature verification succeeds or not;

in response to determining that the signature verification succeeds, generating the new work file that comprises the prior work; and

in response to determining that the signature verification does not succeed, refusing to generate a new work file or generating a work file with a signature verification failure mark.

8. The computer-implemented method of claim 1, wherein the content added based on the operation of the current user comprises content related to a method of use of the prior work or content created by the current user.

9. The computer-implemented method of claim 8, wherein the use method of the prior work comprises forwarding the prior work.

10. The computer-implemented method of claim 8, wherein content created by the current user comprises annotations or comments on the prior work.

11. The computer-implemented method of claim 1, wherein the new work file further comprises a publishing address of the prior work file in the network.

12. The computer-implemented method of claim 1, wherein the prior work comprises prior literary work.

13. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

obtaining, by an end-user device associated with a current user, a prior work file that is not published by the current user in a network, wherein the prior work file comprises a digital signature of a prior author and a prior work;

generating, by the end-user device and based on an operation of the current user, a new work file that comprises the prior work, the digital signature of the prior author, and content added based on the operation of the current user; and

publishing, by the end-user device, the new work file in the network.

14. The computer-readable medium of claim 13, wherein the prior work in the prior work file is encrypted using a private encryption key of the prior author.

15. The computer-readable medium of claim 13, wherein the prior work and the content added based on the operation of the current user in the new work file are encrypted using a private encryption key of the current user, and wherein the new work file further comprises a digital signature of the current user, wherein the digital signature of the current user comprises a digital signature appended, using a private signature key of the current user, to the prior work and the content added based on the operation of the current user.

16. The computer-readable medium of claim 13, wherein generating, by the end-user device and based on an operation of the current user, a new work file that comprises the prior work comprises:

performing signature verification on the prior work using the digital signature of the prior author;

determining whether signature verification succeeds or not;

in response to determining that the signature verification succeeds, generating the new work file that comprises the prior work; and

in response to determining that the signature verification does not succeed, refusing to generate a new work file or generating a work file with a signature verification failure mark.

17. The computer-readable medium of claim 13, wherein the content added based on the operation of the current user comprises content related to a method of use of the prior work or content created by the current user, wherein the method of use comprises forwarding the prior work, or annotations or comments on the prior work.

18. The computer-readable medium of claim 13, wherein the new work file further comprises a publishing address of the prior work file in the network.

19. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising;

obtaining, by an end-user device associated with a current user, a prior work file that is not published by the current user in a network, wherein the prior work file comprises a digital signature of a prior author and a prior work;

generating, by the end-user device and based on an operation of the current user, a new work file that comprises the prior work, the digital signature of the prior author, and content added based on the operation of the current user; and

publishing, by the end-user device, the new work file in the network.

20. The computer-implemented system of claim 19, wherein generating, by the end-user device and based on an operation of the current user, a new work file that comprises the prior work comprises:

performing signature verification on the prior work using the digital signature of the prior author;

determining whether signature verification succeeds or not;

in response to determining that the signature verification succeeds, generating the new work file that comprises the prior work; and

in response to determining that the signature verification does not succeed, refusing to generate a new work file or generating a work file with a signature verification failure mark.
