CoSDEO 2020

This Year’s Theme: Privacy and security in digital assistants

The 7th workshop on Context Systems Design, Evaluation and Optimization (CoSDEO2020) will be held in Austin, Texas, USA in conjunction with the 18th IEEE PerCom which is a premiere conference in Pervasive Computing and Communications (PerCom2020).

Call for Papers

The 7th CoSDEO-workshop aims to bring together researchers and practitioners working on the design, implementation, and evaluation of systems, algorithms or models for smart digital assistants.

The recent proliferation in smart digital assistants holds incredible potential for unprecedented services from (spontaneously networked) devices. Examples include directional audio reception, energy-gentle collaborative processing, unified user-interfaces spanning multiple collaborating devices, context-adaptive optimization of smart digital assistants behavior or device-capability-based intelligent task allocation. Most prominent examples for smart digital assistants are e.g. Alexa, Siri, Echo, Cortana, Google assistant, but also increasingly prominent chat-bots that are intergrated into pervasive applications. Such intelligent smart assistants exploit the recent avent of Artificial Intelligence for situation-dependent service composition conditioned on contextual stimuli from environmental perception. However, together with the technical challenges, privacy concerns, moralities and interface-design aspects of such intelligent machines need to be taken into account.

It is therefore the goal of this workshop to provide a publication and discussion platform for this growing community in which fundamental problems but also sophisticated approaches are presented and discussed.

Thus, we like to encourage practioners and scientists in all stages of their research, from first experiments to readily developed and evaluated systems, to submit their original work to allow a broad discussion with established field experts but also researchers relatively new to the field.

Even if work is in a very early stage, all submitted work must conform to typical scientific requirements; showing a good overview of the field and the specific area of the context of interest. If the paper is based on a technical system, the system should be described and discussed thoroughly.

Besides regular papers, we also encourage submission of visionary papers which must not describe completed research but contain ideas new to the field. These may be related to novel and convenient techniques for key generation and pairing, discussions on entropy and statistical properties of sensor-generated random sequences but also novel applications and designs of smart digital assistants. Topics of interest include but are not limited to:

  • Novel smart digital assistant systems
  • Context-based authentication and pairing
  • Attacks on smart digital assistants
  • Entropy and statistical analysis for keys generated in smart digital assistant systems
  • Novel sensor modalities for context-based authentication or security
  • Case studies in smart digital assistants
  • Distributed Audio-processing in smart digital assistants
  • Moralities and Ethics for smart digital assistants
  • Quantization approaches
  • Novel usable security/privacy mechanisms in the field of pervasive computing
  • Biometric and context-based authentication and pairing
  • Usability evaluations of new or existing security or privacy features
  • User studies in usable security and privacy
  • Lessons learned from the deployment and use of usable and pervasive security
  • User experience in smart digital assistants
  • Security schemes for sharply resource limited devices in Pervasive and IoT environments
  • Privacy and anonymization aspects
  • Novel interfaces fostering usable security and privacy
  • Entropy estimation and statistical analysis
  • Edge-support for usable security on resource limited pervasive devices
  • Lightweight security solutions
  • Detection and prevention of attacks
  • Authentication and access control
  • Trust in smart digital assistants
  • Orchestration and collaboration between devices

Important Dates

  • December 20, 2019: Paper and demo submission deadline
  • January 20, 2020: Notification of acceptance
  • January 31, 2020: Submission of camera-ready deadline

Submission Instructions

CoSDEO is single-blind. Papers may be no more than 6 pages in length (including references; Authors can purchase one additional page for the camera ready version). Papers in excess of page limits shall not be considered for review or publication. All papers must be typeset in double-column IEEE format using 10pt fonts on US letter paper, with all fonts embedded. The IEEE LaTeX and Microsoft Word templates, as well as related information, can be found at the IEEE Computer Society website. Workshop papers will be included and indexed in the IEEE digital libraries (Xplore).

Each accepted workshop paper requires a full PerCom registration (no registration is available for workshops only).

Submit Paper via EDAS
