The "snooper's charter" showed just what the Government is capable of

The proposed "Filter" programme would have been a vast step up in terms of the state's ability to spy on its citizens.

Surveillance technology is of two main types – equipment that keeps tabs on you in the physical world, and processes that track your activity “online” where computers keep a record of your communications and your financial activity.

The physical world is reasonably straightforward to understand. For instance, large numbers of CCTV cameras are installed in public and private spaces in the UK and recordings are kept of what they see. The cameras may be fixed, or a remote operator may be able to choose where they point and how much they zoom in. Newer systems can produce high quality material to enable precise identification of individuals and may also capture audio to accompany the pictures.

“Online” tracking can be equally revealing of people’s actions and movements. Mobile phones continuously interact with nearby cell towers so that incoming calls can be delivered. The phone companies are obliged to retain data about the location of a phone whenever a call is made or received, but if your phone is powered up then they have access to your location at all times and can provide this to law enforcement in real time if this is required.

The records that telephone companies (both fixed line and mobile) keep can be rapidly interrogated to provide lists of calls made from any particular phone, or to any particular phone. These lists will also include the duration of the call and the physical location of the endpoints. Call records can be identified either by the phone number or the phone's unique IMEI device identifier – permitting the tracing of phone activity even when the SIM has been changed.

When interaction is by email instead of by phone then the authorities can still get lists of who is communicating with whom. The email provider is obliged (if they are within the European Union) to keep records of who email was sent to or from, along with timestamp information and exactly how large each email was. Once again, law enforcement regularly requests lists of this email metadata, which can be indexed by sender or receiver.

So far, all of the surveillance and tracking systems have been considered in isolation. One of the provisions of the draft Communications Data Bill was the creation of a data correlation system dubbed a “Filter”. This system would combine enormous amounts of data from different systems, hoping to identify activity that would not have been apparent within a single system.

It is fundamentally inherent to this proposal that Filter data should be collected on everyone’s activity and that this data should be made available en masse from the private companies, the ISPs and telephone companies that provide services, to government systems for the correlation processing. The data won’t necessarily be physically combined on a single system (in fact it would be poor engineering to do this) but it will be logically combined. The original collectors of the data will not have any knowledge of what it is being used for, or possibly even how much data is being processed, so there will be no opportunity for whistle-blowing should excesses occur.

This integrated processing promises to make it much harder for criminals to communicate over a diversity of systems and thereby avoid being tracked – records of phone calls, emails and tweets could be easily combined. But the system’s capabilities go much further than that and the type of “big data” system envisaged will be capable of complex data mining tasks.

To take a fictional example from Charlie Brooker’s National Anthem, the source of a YouTube upload could be identified by the uniqueness of its size and timing; or, closer to real life, the source of an embarrassing leak could be identified by cross-correlating records to pick out exactly who in Whitehall sent out an email whose reception by a journalist triggered an immediate call to the relevant newspaper editor.

The trade-off for these new insights into criminal activity is that more information must be automatically collected about everyone (“just in case”), it must be stored for long periods, measured in years, and it must be handed over to the government operated filter for processing with the inherent assumption that the processing will be necessary, proportionate and authorised. There is tremendous scope for misusing such a system; a police state would relish the opportunity of correlating data on everyone out on the streets for a demonstration, everyone gathering in groups behind closed doors – or just collating a list of everyone who passed on an email containing a subversive joke. The complexity and secrecy of the proposed “Filter” system will make it extremely challenging to ensure that misuse, or just simple “mission creep”, does not occur.

This is an extract of a longer chapter on the technologies of surveillance in from Open Rights Group’s Digital Surveillance report which offers less intrusive alternatives to the Communications Data Bill, or "Snoopers’ Charter", which Nick Clegg blocked last week.

Pegida UK: the new face of Britain’s far-right movement, and how to challenge it

“Let them drink tea,” Birmingham tells Islamophobes.

“Spooky,” is how Pegida UK – the latest branch of a global, anti-Islam, protest group  chooses to describe its silent march on the outskirts of Birmingham. 

“Islam is Nazism incarnate,” announces its new leader, Paul Weston, to a few hundred soggy, sober, brolly-clad protesters waving “Trump is Right” placards.

Such numbers are a far cry from the tens of thousands who attended the movement’s inaugural rallies in Germany in 2014, in response to the perceived “Islamisation” of Europe. And they would be derisory if the cheers Weston receives from his supporters weren’t quite so chilling, nor echoed so far.

For Pegida UK is not alone. From Calais to Canberra, thousands marched in the name of the movement’s toxic platform of anti-immigration and anti-Islam last weekend. I went to see the Birmingham rally to find out why such a protest is taking place in Britain.

"Today is the first of many European wide demonstrations that will bring people together like never before,” Tommy Robinson, UK founder and ex-EDL leader, tells the assembled crowd. “It's planting the seed of something huge.”

Robinson hopes to exploit a gap within Britain’s far-right. Traditional groups are fractured: the British National Party was decimated at the last election, standing just eight of a previous 338 candidates. In its place, a swell of smaller, extremist bodies – from the Sigurd Legion to National Action – are pressing an ever more militant agenda. Pegida hopes to scale back the hooliganism in order to garner a wider appeal, but it shares these groups’ confrontation with Islam, and each may spur the other on.

“With Pegida we’re seeing the rise of a seminal new threat,” says Birmingham MP Liam Byrne. “In the rise of Isis and politicians like Donald Trump, you have forces determined to promote a clash of civilisations between Islam and the West. Pegida is trying to surf that wave and make sure it crashes on our shores.

Opponents hope the movement will suffer the same implosion that felled the BNP and EDL, with both leaning  too much on their leaders’ personal brands. Robinson certainly seems as adolescent as ever: laughing as he swipes away a photo of a scantily-clad blonde on his iPhone screen to show me the international Pegida leadership’s “hidden” Facebook group.

Their new apparently "suited and booted" middle-class following is also less than wholehearted. One pin-striped IT executive I speak to seems embarrassed by the whole affair: “I’m just a cowardly family man who can’t see a solution being offered by mainstream politicians. I’d be sacked if they knew I was here,” he says, declining to give his name.

As long as such hesitation prevails, Pegida UK will struggle. Still, there’s a sense more needs to be done to ensure its demise.

Matching protest with counter-protest is the traditional leftwing response, and this weekend saw thousands of Pegida opponents take to the streets across Europe. Yet, in some cases, direct confrontation can risk drowning out – even alienating – the very voices it seeks to win over.

“Smash the facists into the sea,” instructed the Twitter account of the North London Antifa group ahead of last weekend’s far-right, anti-immigration protest in Dover, where injuries were sustained by demonstrators on both sides.

Instead, many now believe a better answer begins with that most British of pastimes: tea and a chat.

On the day before the Birmingam march, hundreds of the city’s cross-party leaders, religious figures and citizens gathered together at Birmingham Central Mosque to share their concerns over shortcake and jalebi.

“Groups like Pegida are parasites on the real concerns people have,” says John Page from the anti-extremism group Hope not Hate. “So we have to listen to these issues to close the cracks.

Initiatives around the city will attempt to take this approach, which sets a welcome lead not just for the UK, but Europe too.

The blanket smearing by groups like Pegida of Islam as a religion of sexist, homophobic Jihadi Johns places the burden of action disproportionately on the city’s Muslims. “It is our turn now to suffer these attacks,” says Mr Ali, Birmingham Central Mosque’s 42-year-old administrator. “It was the Irish, then the Jews, and now it is the time for us. But we are proud to be British Muslims and we will do what we can to defend this country.” 

A permanent visitors gallery, Visit-my-Mosque events, and publications that condemn Isis, are just some of the ways the community is challenging demonisation. It is even hosting a documentary crew from Channel 4 – a bold move in a city still reeling from Benefits Street.

Mr Ali says: “The extreme right know nothing about Islam, but neither do many Muslim extremists.” The mosque is therefore in the process of formulating a “code of conduct”, making clear that hate speech of any kind is unacceptable.

"We have to help young people become the next Chamberlains and Cadburys and Lucases of this city," regardless of background, says Labour councillor Habib Rehman. Instead of letting them slip into despair and extremism of any kind, "we have to tell them: 'Yes You Khan!’”

Tea and talk is not the most dramatic response to Pegida’s claim it will have “100,000 decent people on the street” by the end of the year. But, in Birmingham at least – the city of Typhoo, where bhangra is as familiar as Bournville, and “No dogs, no Irish!” still sits heavy on the collective mind – tea, for now, means hope.
