GOAL

Quick Report is a mobile application paired with a Bluetooth button in the size of a coin, used for sending predefined messages to a target person. Messages are sent by clicking the button, with each type of click (single, double or long), corresponding to a different notification message.

Click  here to see all places on the world where the Quick Report buttons have been pressed.

HOW IT WORKS

Τhe application sends a predefined text (JSON message), either to a server, or to an email account. It has been developed for both iPhone and Android mobile phones. The application is using a paired button (current implementation comes with a flic button) and can be configured by the user.

  • Report user location (optional)

  • Hide the reporter’s identity – no information about the personal ID of the reporter is sent

  • In cases where identified reports are needed to be provided but the identity of the reporter needs to be concealed, CoNSeRT has developed a Privacy Protection Communication Gateway, through which a two stage, non-reversible process is used to unlink the ID of the reporter from the recipient of the report, so that anonymous reporting can be guaranteed.

Hardware/software requirements

The application and back office services of the smart button, require from the user the app installation and an initial configuration of the reports (i.e. how they should be triggered, what happens after, what information is sent, etc.).

In terms of hardware, any BT enabled clicker/button/ device can be integrated (as long as the corresponding libraries or description of operation are available). The current implementation is using the FLIC company button. A specific number of buttons have been produced for this reason and are available to all interested parties, following communication with CoNSeRT members.

DEPLOYMENT

The Quick Report has been deployed in the Horizon 2020 project TRILLION for incident quick reporting. The user can configure a message to be sent to the TRILLION platform, as well as the incident category (i.e. warning, urgency), depending on the button’s click. The solution has been successfully validated in pilots accomplished in London, by Victoria BID, in the context of TRILLION tests (2018).

A monitoring tool of selected smart buttons’ click location and time has been implemented (always with the consent of the user), able to monitor globally, all clicks. This can be used for cases where heat maps of clicked locations need to be provided, for visualization purposes.

BENEFIT
  • Seamless, discreet and quick reporting, without the need to use a smartphone or smartwatch

  • Easy to use (both in terms of the device, but also of the app, which needs only to be installed and configured with no other input from the user after that).

  • Brevity in location sharing (simply clicking a button one or more times)

  • Transparency in exchanging messages since the button has the size of a coin

Cloud Computing

A CLOUD ON-PREMISES INFRASTRUCTURE
GOAL

CoNSeRT has developed a cloud on-premises infrastructure, supporting several research projects, and academic activities.

DESCRIPTION
  • IaaS solution developed based on OpenStack cloud software

  • Kubernetes platform used for the creation and testing of containerized services

  • Creation of Virtual Machines (VMs) providing access to VCPUs, RAM and Storage over Virtual Networking and Public IPs

  • Off-premises cloud resources provided over the GuNet okeanos platform

  • Redundancy of OpenStack services for high network

  • Data availability is guaranteed through the use of CEPH in all storage nodes

CURRENT STATUS

CoNSeRT ’s cloud infrastructure started as a pilot project over a limited amount of resources (4 physical servers) and built upon a legacy architecture and software offered by the OpenStack community (OpenStack Juno).
Current cloud infrastructure includes:

  • Two OpenStack clouds: (i) production infrastructure, for supporting research projects, and (ii) sandbox infrastructure, for the development of solutions

  • Several servers acting as controllers, compute nodes, and networks routers, using the Free PFsense BSD software

  • Microservers that support the Kubernetes platform, part of an HP Bladesystem

USE OF THE INFRASTRUCTURE IN PROJECTS
STORM project

Implement a robust OpenStack production infrastructure for the protection of Cultural Heritage through Technical and Organisational Resources Management (H2020 project STORM). STORM project exploited the use of several VMs, required by several partners to develop platforms and applications in order to collect and process information gathered by sensors. The cloud infrastructure provided enormous amount of resources and offered high availability characteristics, also safeguarding information of significant importance.

EVE-NG

Emulated Virtual Environment – Next Generation (EVE-NG) is a graphical network emulator built upon OKEANOS cloud, supporting both commercial and open-source router images.

VLABs (Virtual Labs)

Supporting student labs through the creation of custom VMs.

Current cloud infrastructure:

  • 2 OpenStack clouds: (i) production infrastructure, for deploying and offering services supporting research projects, and (ii) sandbox infrastructure, development of solutions.
  • 14 servers serving the roles of controllers, compute nodes and networks routers, featuring the use of PFsense Free BSD software.
  • 8 microservers support the Kubernetes platform, part of an HP Bladesystem.

PRESENTATION

Use cases and applications

  • VLABs (Virtual Labs): Supporting student labs through the creation of custom VMs. The creation of the labs allows students to access powerful VMs and perform demanding actions via thin clients with the minimum hardware.
  • STORM project: Implement a robust OpenStack production infrastructure for the protection of Cultural Heritage through Technical and Organisational Resources Management (H2020 project STORM). STORM project exploited the use of several VMs, required by several partners to develop platforms and applications in order to collect and process information gathered by sensors. The cloud infrastructure provided enormous amount of resources and offered high availability characteristics, also safeguarding information of significant importance.
  • EVE-NG: Emulated Virtual Environment- Next Generation (EVE-NG) is a graphical network emulator built upon OKEANOS cloud, supporting both commercial and open-source router images. It is a virtual network emulator developed for testing and developing real life scenarios of network topologies, before apply them in real topologies.

Cloud Community

Our cloud computing team exchanges ideas with other cloud enthusiasts:

  • Meetings to discuss cloud related issues in meetups organized by the OpenStack Athens User Group.
  • Organization of UniWA campus events for students and researchers
  • Collaboration with companies from the industrial sector (i.e. in Stackmasters)
  • Research other OpenStack deployment projects i.e. OpenStack Kolla and Triple-O OpenStack
