Voice over IP and Communications Traffic Data Retention

Voice over IP and Communications Traffic Data Retention

Voice over Internet Protocol (VoIP) technology is what the entire telecommunications industry is moving over to. It is already available in large companies and as commercial boxed consumer products wich plug into or are part of home ADSL broadband internet connections.

  1. Do remember that Voice over IP systems, like Skype, whilst they do offer privacy regarding the contents of the the conversation due to encryption, do not offer anonymity against Communications Traffic Data Analysis i.e. who called whom and when, which is often enough for a "whistleblower" to be identified in a "leak investigation". See the comments below.

  2. Remember that VoIP operates in two modes - e.g. Skype to Skype, which is only useful if your journalist or blogger contact also uses Skype. Guido Fawkes does publish a Skype number, and Iain Dale has used Skype for video conferences etc. but does not publish his number. No major media organisations publish a Skype number, although this might well be arranged after an initial contact.

  3. The second mode is Skype (or other VoIP technology) to the normal land line or mobile phone network via a gateway.

    Obviously the normal phone network part of the call suffers from all the problems mentioned above, especially to mainstream media phones which are on the "terrorist alert" watch list.

    However, it is possible to use some Voice over IP systems such Vonage, to make it appear to Caller ID systems that your phone call is coming from another country. This is often enough to prevent Caller ID features on a UK land line and mobile phones from working to reveal the number you are dialling from, either through the 1471 callback feature, or on itemised phone bills of the sort which are sent to normal customers.

    This is only slightly more "secure" than pre-fixing your land line or mobile phone call with 141

    Neither of these techniques are enough to protect the number you are calling from being revealed to an official UK Communications Traffic Data request, since the Networks do retain this data during at least the current billing cycle and longer. The European Union has agreed a Directive to Retain such Communications Traffic Data for at least a year, for all 450 million EU citizens, who are innocent of any crime "just in case".

    Thankfully, has not been implemented, yet Unfortunately this Mandatory Data Retention of Communications Traffic Data came into force legally in the United Kingdom, in October 2007, initially for landline telephone and mobile phone data. There is an 18 month delay before this applies to internet data.

    i.e. VoIP to VoIP call Communications Traffic Data log files are not yet Retained, but VoIP to landline or mobile phone and vice versa is.

    Internet connection access logs and email server logfiles, together with "Internet telephony" log files, are due to be retained from March 2009 onwards, for 2 years at a time, when the full implementation of the EC Directive comes into force.

About this blog

We know that there are decent, honest, trustworthy individual politicians, civil servants, law enforcement, intelligence agency personnel and broadcast, print and internet journalists etc., who often feel powerless or trapped in the system. They need the assistance of external, detailed, informed, public scrutiny to help them to resist deliberate or unthinking policies, which erode our freedoms and liberties.

Some of these people will, in the public interest, act as whistleblowers, and may try to leak documents or information to the mainstream media, or to political blog websites etc.

Here are some Spy Blog "Hints and Tips", giving some basic preecautions, and some more obscure technical tips, which both whistleblowers, journalists, and bloggers need to be aware of, in order to help preserve the anonymity of whisteleblowing or other journalistic sources, especially in the United Kingdom, but applicable in other countries as well.

Whistleblower anonymity may not always be possible, or even necessary, forever into the future, but it is usuially crucial during at least the early stages of a "leak", whilst it is being evaluated by others, to see if it merits wider publication and publicity.

Tor Hidden Service

In order to make censorship a little more difficult, a copy of this Hints and Tips for Whistleblowers guide is also being published as a Tor Hidden Service.

You will need to have installed the Tor software and established a working Tor connection, and then you will be able access this copy via end to end encryption and a high degree of anonymity through the Tor cloud:

If you do not have Tor installed, you can still access this Hidden Service via the tor2web.org proxy: https://r3lb3r3an7uj7bos.tor2web.org/ still with encryption, but without as much anonymity.

Tor - the onion routing network - "Tor aims to defend against traffic analysis, a form of network surveillance that threatens personal anonymity and privacy, confidential business activities and relationships, and state security. Communications are bounced around a distributed network of servers called onion routers, protecting you from websites that build profiles of your interests, local eavesdroppers that read your data or learn what sites you visit, and even the onion routers themselves."
