Version 1 of Passive optical fingerprint scanner for fiber optic remote authentication

We try to timestamp all uploads so that ideas' authors can prove inventorship. Below you find a list of TSAs (trusted timestamping authorities) used for this upload, along with their certificates. Using the certificates, the (hash of the) original documents and the all-important tsr-files, with a cryptographic software like OpenSSL, it is possible to check that the below timestamps are correct (further details e.g. here).

We recommend that the idea's author download a copy of all the documents below for personal safekeeping. Note also that we link to the latest certificates only, which may be different from those used for actual timestamping if files are older.
