Call for Research Papers
==============================================================
Papers offering novel research contributions are solicited for submission. Accepted papers will be presented at the symposium and published by the ACM in the symposium proceedings. We also encourage submissions to the "Work-in-progress Track" to present ideas that may have not been completely developed and experimentally evaluated. In addition to the regular research track, this year SACMAT will again host the special track – "Blue Sky/Vision Track". Researchers are invited to submit papers describing promising new ideas and challenges of interest to the community as well as access control needs emerging from other fields. We are particularly looking for potentially disruptive and new ideas which can shape the research agenda for the next 10 years.

Submission Cycles
-------------------------
ACM SACMAT 2023 Regular and Work-in-progress Tracks will have two submission cycles. Authors submitting papers in the first submission cycle will have the opportunity to receive a major revision verdict in addition to the usual accept and reject verdicts. Authors can decide to prepare a revised version of the paper and submit it to the second submission cycle for consideration. Major revision papers will be reviewed by the program committee members based on the criteria set forward by them in the first submission cycle.

Paper Submission and Format
-------------------------

** Regular Track Paper **
Papers must be written in English. Authors are required to use the ACM format for papers, using the two-column SIG Proceedings Template (the sigconf template for LaTex) available in the following link: https://www.acm.org/publications/authors/submissions

The length of the paper in the proceedings format must not exceed twelve US letter pages formatted for 8.5" x 11" paper and be no more than 5MB in size. It is the responsibility of the authors to ensure that their submission will print easily on simple default configurations. The submission must be anonymous, so information that might identify the authors - including author names, affiliations, acknowledgements, or obvious self-citations - must be excluded. It is the authors' responsibility to ensure that their anonymity is preserved when citing their own work. Submissions should be made by the paper submission deadline to the EasyChair conference management system (https://easychair.org/my/conference?conf=acmsacmat2023).

When submitting papers, please pay attention to the submission cycle you are submitting in.

All submissions must contain a significant original contribution. That is, submitted papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal, conference, or workshop. In particular, simultaneous submission of the same work is not allowed. Wherever appropriate, relevant related work, including that of the authors, must be cited. Submissions that are not accepted as full papers may be invited to appear as short papers. At least one author from each accepted paper must register for the conference prior to the camera-ready deadline and is required to (physically) present it at the conference.

** Work-in-progress Track **
Authors are invited to submit papers in the newly introduced work-in-progress track. This track is introduced for (junior) authors, ideally Ph.D. and Master's students, to obtain early, constructive feedback on their work. Submissions in this track should follow the same format as for the regular track papers while limiting the total number of pages to six US letter pages. Paper submitted in this track should be anonymized and can be submitted by the same deadline as for the regular track to the EasyChair conference management system (https://easychair.org/my/conference?conf=acmsacmat2023)

** Blue Sky Track **
All submissions to this track should be in the same format as for the regular track, but the length must not exceed ten US letter pages, and the submissions are not required to be anonymized (optional). Submissions to this track should be submitted by the same deadlines as the ones for the second cycle of the regular track to the EasyChair conference management system (https://easychair.org/my/conference?conf=acmsacmat2023).


Other Calls
==============================================================

Call for Demos
-------------------------
A demonstration proposal should clearly describe (1) the overall architecture of the system or technology to be demonstrated, and (2) one or more demonstration scenarios that describe how the audience, interacting with the demonstration system or the demonstrator, will gain an understanding of the underlying technology. Submissions will be evaluated based on the motivation of the work behind the use of the system or technology to be demonstrated and its novelty.

Demonstration proposals should be in the same format as for the regular track, but the length must not exceed four US letter pages, and the submission should not be anonymized. A two-page description of the demonstration will be included in the conference proceedings. Submissions are expected to be submitted through the EasyChair conference management system (https://easychair.org/my/conference?conf=acmsacmat2023) by the demo submission deadline.

Call for Posters
-------------------------
SACMAT 2023 will include a poster session to promote discussion of ongoing projects among researchers in the field of access control and computer security. Posters can cover preliminary or exploratory work with interesting ideas, or research projects in early stages with promising results in all aspects of access control and computer security. Authors interested in displaying a poster must submit a poster abstract in the same format as for the regular track, but the length must not exceed three US letter pages, and the submission should not be anonymized. Accepted poster abstracts will be included in the conference proceedings.

Submissions are expected to be submitted through the EasyChair conference management system (https://easychair.org/my/conference?conf=acmsacmat2023) by the poster submission deadline.

Financial Conflict of Interest (COI) Disclosure:
==============================================================
In the interests of transparency and to help readers form their own judgments of potential bias, ACM SACMAT requires authors and PC members to declare any competing financial and/or non-financial interests in relation to the work described.

Definition
-------------------------
For the purposes of this policy, competing interests are defined as financial and non-financial interests that could directly undermine, or be perceived to undermine the objectivity, integrity, and value of a publication, through a potential influence on the judgments and actions of authors with regard to objective data presentation, analysis, and interpretation.

Financial competing interests include any of the following:

* Funding: Research support (including salaries, equipment, supplies, and other expenses) by organizations that may gain or lose financially through this publication. A specific role for the funding provider in the conceptualization, design, data collection, analysis, decision to publish, or preparation of the manuscript, should be disclosed.

* Employment: Recent (while engaged in the research project), present or anticipated employment by any organization that may gain or lose financially through this publication.

* Personal financial interests: Ownership or contractual interest in stocks or shares of companies that may gain or lose financially through publication; consultation fees or other forms of remuneration (including reimbursements for attending symposia) from organizations that may gain or lose financially; patents or patent applications (awarded or pending) filed by the authors or their institutions whose value may be affected by publication. For patents and patent applications, disclosure of the following information is requested: patent applicant (whether author or institution), name of the inventor(s), application number, the status of the application, specific aspect of manuscript covered in the patent application.

It is difficult to specify a threshold at which a financial interest becomes significant, but note that many US universities require faculty members to disclose interests exceeding $10,000 or 5% equity in a company. Any such figure is necessarily arbitrary, so we offer as one possible practical alternative guideline: "Any undeclared competing financial interests that could embarrass you were they to become publicly known after your work was published."

We do not consider diversified mutual funds or investment trusts to constitute a competing financial interest. Also, for employees in non-executive or leadership positions, we do not consider financial interest related to stocks or shares in their company to constitute a competing financial interest, as long as they are publishing under their company affiliation.

* Non-financial competing interests: Non-financial competing interests can take different forms, including personal or professional relations with organizations and individuals. We would encourage authors and PC members to declare any unpaid roles or relationships that might have a bearing on the publication process. Examples of non-financial competing interests include (but are not limited to):
** Unpaid membership in a government or non-governmental organization
** Unpaid membership in an advocacy or lobbying organization
** Unpaid advisory position in a commercial organization
** Writing or consulting for an educational company
** Acting as an expert witness
