Needs support for slide upload

[kaymckelly]

If people could claim ownership on their cryptodb records, then this would be easy to implement. Alternatively, we could have websubrev send out emails with custom urls for each paper. These would go to the corresponding author. If we switch to hotcrp, we'd need similar support.

Alternatively, we could provide an app that requires IACR login and presents a list of papers for the conference. Authors would then be responsible for selecting their paper and uploading the slides for it. The risks are that an author could select the wrong paper, which could cause chaos at the conference. Once a paper is claimed, it no longer appears in the list presented to authors for choosing where to upload their slides. One failure mode is if one author uploads slides, then another co-author is assigned at the last minute to give the talk and cannot upload new slides.

Note that Crypto maintains their own server to upload slides (we think).

This is also related to the way IACR handles paper reviews. @cca88 should be aware of this.

When we entered covid, we provided a way for authors to upload their slides. The mechanism is to send them a pre-authorized URL that allows them to upload slides, and then they go into an area on s3. We have been linking to slides in the program by exporting the links from s3 into an extra links file, which is then processed by currentProgram.php. At present this isn't checked in because it requires authentication credentials for each conference, but the logical step is to provide a way for pulling the list of slides from s3.
