CEAS 2006
Brainstorming Session on “What's missing?”

7/28/2006

Overlooked or substantially more research needed

Search engines for e-mail archives (e.g., query expansion, hubs/authorities).

N-factor performance evaluation.

Reputation vs. privacy.

Emergence of rep as requirement; impact on privacy such as making anonymity impossible?

Real time usefulness of analysis techniques.

Researchers need to consider computational load and other performance impact on real-time analysis.

How many spammer are there?

Policy people need this info (cf, Linford) because it has a large effect on how to approach dealing with the problem

Cell phone spam/text messaging.

Emerging problem

Image spam

Taking research from efficient computer vision algorithms and applying them to spam detection

Detecting forwarding and handling spam in forwarding

research, standards, proposals for standardisation of forwarding

Dealing with Advanced CSS based SPAM - advanced html spam

If spammers become advanced, can hire cheaply programmers from countries to which we outsource software, they can become really advanced in what they can send in spam

Research on how to tackle the new variants of spam and a common technique to deal with any new variants of html obfuscation.

Collaborative detection of botnets by anti spam communities

Research on how we can help the government by providing thru a secure backchannel, information and evidence about spammers

Collaborative Detection of botnets on internet

Browser/operating system mandatory enhancement to monitor port 25 connections and reporting users about arbitrary port 25 connections - hence detecting botnets

Methods from other scientific areas

Usability evaluations using HCI methods, not just accuracy figures.

Learning model for adversarial classification.

Remove human factor from decision-making

Lack unified model; need one

Economic restrictions on the usefulness of spam – is there a mutation rate that is so high that spam is no longer profitable?

Economics and security; need to cross-pollinate the two areas, to work together; spam as a problem is a consumption of our time/resources

Can better filters make spam uneconomical

Lessons from war

Can the methods used to study military tactics help us in the fight against spam? Possible collaborative topic for spam researcher to work with people from the national war college or other academic military strategy field.

HCI and psych of users interacting with junkmail filters

Do they feel like they are ‘combatting’ spam?

“User perceptions” of the mechanisms.

New products or services that require novel research

Search for email from dead people

Social network & content techniques needed

Need corpora that are relevant to this r&D

Importance of layout (Format templates)

Eg, “Mortgage” spam.

Look at web, to find email spammers

Eg, pharmacy spam leads to web links, and web pages produce common terminology that makes identifying spam email easier.

VOIP spam; real-time spam; eg, based on noticing current activity(!)

Authentication requires Accred/Cert/Rep mechanisms

Which mechanisms are the most useful?

What are differential aspects of using each?

How to bootstrap their use?

More realistic models of costs for delivery/non-delivery

Real-time performance issues.  Collaborative filtering role? Requirement?

Domain names and phone numbers are cheaper; encourages more spam

R&D to hold registrars held (more) responsible

Partial user feedback

Partial correction; impact of imperfect performance on correcting

Other

Less on spam, more on anti-virus, time-delay for propogation, how companies use attachments,  General email research.

More effort on lawsuits against spammers; research on impact

Moving from UBE definition to “unwanted”

How to classify; how handled; ...
