Orphaned non-free media (File:Guardttime_timestamping_newspaper_publication.png)
Thanks for uploading File:Guardttime_timestamping_newspaper_publication.png. The media description page currently specifies that it is non-free and may only be used on Wikipedia under a claim of fair use. However, it is currently orphaned, meaning that it is not used in any articles on Wikipedia. If the media was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that media for which a replacement could be created are not acceptable for use on Wikipedia (see our policy for non-free media).

If you have uploaded other unlicensed media, please check whether they're used in any articles or not. You can find a list of 'file' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "File" from the dropdown box. Note that all non-free media not used in any articles will be deleted after seven days, as described on criteria for speedy deletion. Thank you. Melesse (talk) 02:29, 12 January 2010 (UTC)

Fair use rationale for File:Guardtime timestamping newspaper publication.png
Thanks for uploading or contributing to File:Guardtime timestamping newspaper publication.png. I notice the file page specifies that the file is being used under fair use but there is not a suitable explanation or rationale as to why each specific use in Wikipedia constitutes fair use. Please go to the file description page and edit it to include a fair use rationale.

If you have uploaded other fair use media, consider checking that you have specified the fair use rationale on those pages too. You can find a list of 'file' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "File" from the dropdown box. Note that any non-free media lacking such an explanation will be deleted one week after they have been tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. Sfan00 IMG (talk) 15:22, 22 October 2010 (UTC)

Qualifications for File:Hashtree_timestamping.svg
Thanks for uploading this representation of a hash tree for the purpose of linked timestamping. I am curious how you decided this shape versus others. For example, it seems that a root hash such as t could be a leaf of the next hash tree for linking. I have not read all the pertinent specifications but this method would seem to work under RFC 6283 and ANSI X9.95. Clarification on how you selected the method depicted would be much appreciated. — Preceding unsigned comment added by Glom2215 (talk • contribs) 22:32, 2 January 2012 (UTC)

Non-free rationale for File:Guardtime timestamping newspaper publication.png
Thanks for uploading or contributing to File:Guardtime timestamping newspaper publication.png. I notice the file page specifies that the file is being used under non-free content criteria, but there is not a suitable explanation or rationale as to why each specific use in Wikipedia is acceptable. Please go to the file description page, and edit it to include a non-free rationale.

If you have uploaded other non-free media, consider checking that you have specified the non-free rationale on those pages too. You can find a list of 'file' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "File" from the dropdown box. Note that any non-free media lacking such an explanation will be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem. If you have any questions, please ask them at the Media copyright questions page.
