1. M. Barni called for the meeting at 20:00.

2. TC Status Report
Barni reported the current state of the TC summarizing the main achievements since last meeting in Seattle.

  1. The web site has been expanded thanks to the efforts of the web site subcom. G. Doerr gave a detailed report on the news included in the web site and invited all the TC members to populate the site with particular reference to news to be posted on the message board and job offers for the job market-place.
  2. M. Barni reported about the new composition of TC subcoms after the election of new members. All the subcoms are now numerous enough to carry out the tasks assigned to them.
  3. M. Barni reported about the establishment of Interest areas and the corresponding area chairs. The current list of interest areas and area chairs is as follows:
    • Data hiding (steganography, steganalysis, watermarking). Chair: F. Perez-Gonzalez
    • Multimedia security (robust hashing, DRM, multimedia forensics). Chair: G. Doërr
    • Signal processing and cryptography (secure signal processing, multimedia encryption, privacy protection). Chair: S. Katzenbeisser
    • Network security. Chair: W. Trappe
    • Biometric security. Chair: P. Campisi
    • Video-surveillance. Chair: M. Liao
    • Information theoretic aspects of security. Chair: tbd
    • Applications and systems (including emerging issues like security issues in cloud computing, smart grids, social networks). Chair: J. Kuo
  4. M. Barni reviewed the current composition of the TC that now consists of 32 regular members, 2 associate members and 45 affiliate members. J. Kuo suggested that retired members of the TC could be invited as associate members. It is agreed that the TC chair will invited those among retired members that were more active within the TC during their term.

3. Distinguished Lecturer nominations
Barni announced the results of the DL nomination ballot. As a result of the ballot the nominations of T. Kalker and P. Moulin have been approved and will be forwarded to the SPS award committee.

4. WIFS 2011
D. Florencio gave report on the status of the organization of WIFS 2011. The following major points were clarified:

  • TC members were reminded that one of the pro’s of holding WIFS 2011 in Brasil was that in the same days the ICMedia (International Conference on Multimedia Forensics, Surveillance and Security) event organized by the DPF (Departimento de Policia federal) is held, thus creating opportunities for interesting synergies. For the same reason DPF promised to sponsor WIFS’11 at a significant level. Concerns were expressed by G. Doerr and M. Barni regarding the fact that the organization of ICMedia seems to be quite late. Florencio reassured the TC that even if the ICmedia event has not been advertised yet (and the contract between ICMedia organizers and DPF not signed), it is pretty sure that such an event will take place in concomitance with WIFS. It is then agreed to mention ICMedia when advertising WIFS 2011.
  • J. Kuo reported about the web site submission system, that is ready to be put on-line after a last double check.
  • J. Kuo said that keynote speakers have already been defined. They are: T. Kalker, P. Flynn, and W. Horn. The name of keynote speakers will be made public as soon as the title of the talks will be available.
  • Six tutorial proposal have been received. The organizing committee plans to accept 3 of them.

5. WIFS 2012
G. Doerr reported about the call for proposals for WIFS. At least two such proposals should be submitted. Barni raised the issue of a possible date change of WIFS 2012 that could be held in early September instead of late November/December. A long discussion followed, during which the pros and cons of holding WIFS in September were highlighted. Among the pros the most important ones TC members mentioned: less academic duties with respect to December, better weather conditions in most parts of the world. Among the cons, the necessity of staying away from ICIP, and the large number of conferences and workshop already organized in September were mentioned. The proposal of holding WIFS in January was also advanced. At the end of the discussion it was clear to everybody that no ideal solution exists, so it is suggested that a poll is carried out among TC members (regular, associate and affiliate) to gather additional information. The poll is going to be run by the WIFS subcom of the TC.
Another related issue that was discussed is the possibility of merging WIFS with other conferences/workshops roughly covering the same topics. Some members expressed the opinion that the TC should seriously consider this possibility since a number of security-oriented conferences are facing a hard time in attracting a sufficient number of good submissions, and merging could help to solve this problem. Others observed that WIFS is not experiencing this difficulty and hence there’s no need for a merge from WIFS’s side. It was also noted that we should let WIFS grow and consolidate its reputation before thinking about a merge. Finally the problem of loosing control over WIFS in case of a merge was raised.

6. Number of submission to ICASSP.
Barni reported about the number of papers submitted to ICASSP 2011 under the IFS-­Track. He noticed how such number decreased with respect to previous editions, and suggested that the TC should take some actions to cope with this problem. Barni recalled that, during the TC meeting in Seattle (December 2010, WIFS), it was suggested that the TC explores with the Society leadership for a notion of "IFS Track at ICASSP". The track was intended to increase the appealing of ICASSP outside the SP community. Several participants including A. Tewfik and T. Kalker noted that even with such an effort it is unlikely that (at least in the short term) researchers not belonging to the SP community will ever consider ICASSP as a premier venue for them, hence establishing and IFS track as proposed is likely to be a useless effort. They suggest that it would be a more effective strategy to devote outreach effort in growing WIFS first. After a thorough discussion it is decided that priority should be given to attract new submissions (especially from outside the SP community) to WIFS that is likely to be in a better position to attract external researchers. In a second phase, some attendants of WIFS will eventually be invited to attend ICASSP as well.
As to ICASSP, it was decided to make an effort to increase the participation among SP researchers. Barni observed that the EDICS of the IFS-TC used for ICASSP should be updated. Doerr confirmed this necessity by commenting on the fact that this year there were some IFS-relevant papers that were published in other areas (e.g. MMSP P1 & P3 where *5* watermarking posters were presented in total). M. Wu observed that a similar effort is being carried out in parallel by TIFS EDICS. A small working group is then formed to liaise with TIFS EB and come out with a new version of TC EDICS to be approved before the end of June so to be adopted by next ICASSP. The working group is formed by: A. Piva, J. Kuo and N. Memon. As a final note, Barni invited all TC members to submit their paper to ICASSP starting from next edition.

7. TC balance.
M. Barni expressed his concern that some areas relevant to the TC’s scope are not adequately represented within the TC. It is suggest that two lines of actions are undertaken to face with this problem:

  • Pay attention to technical coverage during the next election of new members. The nomination and election process should be carried out in such a way that a good balance among technical areas, as well as among geographical areas, is reached. Zhao suggested that the election subcom considers the possibility of using a tool like the one adopted for the election procedure within the MMSP TC.
  • Appoint associate members covering the under-represented areas. It is noted in fact that it is likely to be easier to involve personalities outside the SP community as associate rather then as regular members. The same should be done to reach a better coverage of geographical areas and to liaise with industry.

8. IFS competition.
Barni led the discussion regarding the opportunity of organizing a challenge (competition) on an IFS theme. Such an opportunity would fit will with the idea launched by SPS to organize one or more SP cups. Everybody agreed that this is a good idea. Different opinions are expressed about the audience that should be targeted by the competition. A. Tewfik recommended that he competition be directed to researchers. M. Wu noticed that the SP cup is likely to be more oriented towards undergraduate students and suggested that the IFS competition is organized in such a way to address both researchers and undergraduate students. With regard to the possible topic(s) addressed by the competition, Barni recommended that the TC organize the competition in an area where it has a good reputation, so that the competition is scientifically credible. Several proposals are made including: image forensics, biometrics, smart grid security. At the end of the discussion it is decided that M. Barni will raise this issue via e-mail so to gather more reactions and be ready to submit a proposal to SP technical direction board before the Summer.

9. Next meeting.
The next TC meeting will be held in Foz Do Iguacu, Brazil, during WIFS 2011 (29 November – 2 December 2011).
The meeting was adjourned without objection
