A package was submitted to savannah.gnu.org
This mail was sent to address@hidden, address@hidden
Ole Tange <address@hidden> described the package as follows:
License: gpl
Other License:
Package: Proofs-of-Prior-Art
System name: popa
Type: 2
Description:
Proofs of prior art (PoPA).
This project is for implementing the idea from support ID #100992:
https://savannah.gnu.org/support/?func=detailsupport&support_id=100992&group_id=11
In the future software patents will become a larger problem. One of the things
that can invalidate a patent is prior art. There is no doubt that Savannah will
contain stuff that can be used as prior
art. Also there is a risk that some Savannah users may be sued injusticely
simple because they seem to infringe a patent but where the Savannah user has
prior art.
So what we need to do is to be able to prove in court that the given file in
CVS _did_ exist at a given point in time. Here is a simple way to do that:
* md5sum all files
* put the md5sums into a file called M-all
* publish the md5sum of M-all in a printed newspaper (i.e. a free-ads paper)
* store M-all for future use
This should be done periodically (once a month will probably be
sufficient). With the published md5sum it should be possble to prove
in court that M-all did indeed exist at the time of publishing. And with M-all
it should be possble to prove in court that the file in question did indeed
exist before the time of publishing.
The reason for not using GPG-signatures is that this may confuse matters in
court. Who has signed the files is _not_ important. What _is_ important is that
the file did exist at a given point in time.
The files in this project will be dated versions of M-all and when and where
M-all\'s md5sum was published.
The project does not exist and I will need help from savannahs sysadmins to
rsync all projects and extract all version of all files of all CVS repositories.
Other Software Required:
rsync (ssh)
CVS
md5sum
perl
