  • Policy Options and Regulatory Mechanisms for Managing Radicalization on the Internet
    Policy options and regulatory mechanisms for managing radicalization on the Internet Paris, 30 September 2016 “[…] I firmly believe that in a free democratic society, freedom of speech and expression is one of the most prized freedoms which must be defended and upheld at any cost and this should be particularly so in the land of Voltaire. It is indeed unfortunate that in the world of today, when science and technology have advanced the frontiers of knowledge and mankind is beginning to realize that human happiness can be realized only through inter-dependence and cooperation, the threshold of tolerance should be going down. It is high time man should realize his spiritual dimension and replace bitterness and hatred by love and compassion, tolerance and forgiveness.” Justice Prafullachandra Bhagwati Dan Shefet (Individual Specialist) ACKNOWLEDGEMENTS The author wishes to thank the following for their support, valuable advice and input throughout the drafting of the Report: Dr. Indrajit Banerjee and his team in UNESCO’s Knowledge Societies Division The UNESCO Delegates and Ministries of Justice/Interior of countries that have participated in the Country Survey.

Today's goal is to help you understand why you want protec@on for these points of exposure, and how to select a solu@on. • Both of these topics are the subject of pending dra documents in the Pervasive Monitoring SIG. 2 I. Messaging Other Than Email 3 Messaging Other Than Email • M3AAWG has been working hard on protec@ng email against pervasive monitoring. • That's very important work, and protec@ng email privacy is a totally appropriate goal for M3AAWG. • Although M3AAWG has always had a strong focus on email, our charter, as the an@-Pervasive Monitoring SIG of the Messaging, Malware, and Mobile An-Abuse Working Group, includes, or should include, protec@ng mobile voice telephony and mobile applicaons (such as tex@ng/chat), too. • Arguably, for many users, secure mobile voice and secure text/ chat is as important, or even more important than email.

    Hindawi Publishing Corporation Advances in Multimedia Volume 2011, Article ID 372591, 21 pages doi:10.1155/2011/372591 Research Article A Survey of Open Source Products for Building a SIP Communication Platform Pavel Segec and Tatiana Kovacikova Department of InfoCom Networks, University of Zilina, Univerzitna 8215/1, 010 26 Zilina, Slovakia Correspondence should be addressed to Tatiana Kovacikova, [email protected] Received 29 July 2011; Revised 31 October 2011; Accepted 15 November 2011 Academic Editor: T. Turletti Copyright © 2011 P. Segec and T. Kovacikova. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The Session Initiation Protocol (SIP) is a multimedia signalling protocol that has evolved into a widely adopted communication standard. The integration of SIP into existing IP networks has fostered IP networks becoming a convergence platform for both real- time and non-real-time multimedia communications. This converged platform integrates data, voice, video, presence, messaging, and conference services into a single network that offers new communication experiences for users. The open source community has contributed to SIP adoption through the development of open source software for both SIP clients and servers. In this paper, we provide a survey on open SIP systems that can be built using publically available software. We identify SIP features for service deve- lopment and programming, services and applications of a SIP-converged platform, and the most important technologies support- ing SIP functionalities. We propose an advanced converged IP communication platform that uses SIP for service delivery.

  • Linphone a Good Working Skype Voice Over IP Alternative
    Walking in Light with Christ - Faith, Computing, Diary Articles & tips and tricks on GNU/Linux, FreeBSD, Windows, mobile phone articles, religious related texts http://www.pc-freak.net/blog Linphone a good working Skype voice over IP alternative Author : admin If you never tried linphone I warmly recommend it. 2 days ago, with a friend of mine we tested a bunch of Linux softwares to find out what is the situation with possible alternatives to Skype to transmit Voice and Video. I've been interested into Skype Alternative programs since about 2 years, but so far I never found good and easy to set up working Linux alternative. We first tried Ekiga. Though it is said to be a good Linux SKype alternative, my ekiga client running on Debian Linux stable Squeeze ver. 3.2.7.2 failed to connect to SIP account I've created on ekiga.net. I've tried hard to make ekiga connect to account SIP created from ekiga.net but all time I was getting an error on connect: Ekiga did not manage to configure your network settings automatically. You can still use it, but you need to configure your network settings manually. Please see http://wiki.ekiga.org/index.php/Enable_port_forwarding_manually for instructions After continously trying to follow instructions from above pointed URL and making proper settings on my DL-524 Wireless Router and all time ending up with the annoying error, we decided to finally completely abondoned it and try some other voice over IP clients. We tried Jitsi and few others which prooved to be unworking.

  • Online Security for Independent Media and Civil Society Activists
    Online Security for Independent Media and Civil Society Activists A white paper for SIDA’s October 2010 “Exile Media” conference Eric S Johnson (updated 13 Oct 2013) For activists who make it a priority to deliver news to citizens of countries which try to control the information to which their citizens have access, the internet has provided massive new opportunities. But those countries’ governments also realise ICTs’ potential and implement countermeasures to impede the delivery of independent news via the internet. This paper covers what exile media can or should do to protect itself, addressing three categories of issues: common computer security precautions, defense against targeted attacks, and circumventing cybercensorship, with a final note about overkill (aka FUD: fear, uncertainty, doubt). For each of the issues mentioned below, specific ex- amples from within the human rights or freedom of expression world can be provided where non-observance was cata- strophic, but most of those who suffered problems would rather not be named. [NB Snowden- gate changed little or nothing about these recommendations.] Common computer security: The best defense is a good … (aka “lock your doors”) The main threats to exile media’s successful use of ICTs—and solutions—are the same as for any other computer user: 1) Ensure all software automatically patches itself regularly against newly-discovered secu- rity flaws (e.g. to maintain up-to-date SSL certificate revocation lists). As with antivirus software, this may cost something; e.g. with Microsoft (Windows and Office), it may re- quire your software be legally purchased (or use the WSUS Offline Update tool, which helps in low-bandwidth environments).

  • Modeling and Analysis of Next Generation 9-1-1 Emergency Medical Dispatch Protocols
    MODELING AND ANALYSIS OF NEXT GENERATION 9-1-1 EMERGENCY MEDICAL DISPATCH PROTOCOLS Neeraj Kant Gupta, BE(EE), MBA, MS(CS) Dissertation Prepared for the Degree of DOCTOR OF PHILOSOPHY UNIVERSITY OF NORTH TEXAS August 2013 APPROVED: Ram Dantu, Major Professor Kathleen Swigger, Committe Member Paul Tarau, Committee Member Sam G Pitroda Committee Member Barrett Bryant, Chair of the Department of Computer Science and Engineering Costas Tsatsoulis, Dean of the College of Engineering Mark Wardell, Dean of the Toulouse Graduate School Gupta, Neeraj Kant. Modeling and Analysis of Next Generation 9-1-1 Emergency Medical Dispatch Protocols. Doctor of Philosophy (Computer Science), August 2013, 192 pp., 12 tables, 72 figures, bibliography, 196 titles. In this thesis I analyze and model the emergency medical dispatch protocols for Next Generation 9-1-1 (NG9-1-1) architecture. I have identified various technical aspects to improve the NG9-1-1 dispatch protocols. The specific contributions in this thesis include developing applications that use smartphone sensors. The CPR application uses the smartphone to help administer effective CPR even if the person is not trained. The application makes the CPR process closed loop, i.e., the person who administers the CPR as well as the 9-1-1 operator receive feedback and prompt from the application about the correctness of the CPR. The breathing application analyzes the quality of breathing of the affected person and automatically sends the information to the 9-1-1 operator. In order to improve the human computer interface at the caller and the operator end, I have analyzed Fitts law and extended it so that it can be used to improve the instructions given to a caller.
