The 'request filter' is signature driven
the Detika DPI boxes will be loaded with todays's signature list i.e. immediately pass on all data which contains the following hex block "C3 P0 R2 D2..." with the boxes then encrypting the intercept packets and sending it down a port to whichever group owns the big hard-disks to then start collating the data. Is that Utah or Ohio or Chelyabinsk - is IMP/CCDP just an NSA front-end?
Who will provide the hit-list of hex signatures to load into the Detika DPI boxes? i.e. is IMP/CCDP just another NSA front-end?
This graphic example of an IMP/CCDP shows PhD students best guess on their national system based on documents leaked to Sveriges Radio http://upload.wikimedia.org/wikipedia/commons/b/b6/Trafikdata-en.png (nice picture that puts much of the "filtering" in context)
I don't think there will be that many humans involved in the filtering, and the rejection ratio will depend on how big the UK's strategic national hard-disks are as they'll always be nearly but not quite full. Assuming a big enough storage - then you can assume total traffic capture and forwarding.
Access to the 'Analysis' & 'report' databases would hopefully have some accounting and auditing - but UK has until quite recently denied that there was much/any illegal snooping inside snoop databases by privileged users.
What to do about IMP/CCDP part One?
★well you can try understanding it, we need sociologists!
★write a letter to your MP explaining in simple terms what could happen.
★You can write a fictional novel about a future UK where IMP/CCDP misuse is rampant. (for guidance: you can read the short e-book "From Dictatorship to Democracy" that the US State Department seems to use as a guidebook when 'colourfully' overthrowing regimes in Serbia/Thailand/Ukraine.....Egypt/Syria/Iran? link: http://www.aeinstein.org/organizations/org/FDTD.pdf
★Perhaps someone should write the corollary e-Book "From Democracy to Dictatorship" on the demise of thousand years of UK freedoms based on the introduction of IMP/CCDP to a sleeping UK population?
The BIG problem is that the slightly future internet will have IMP/CCDP just as an intelligent app built-in to the network - the power and flexibility of the software defined networking (SDN means that all the TCP/IP routers will be trivially able to rule-based filter - the internet is no-longer a slightly drunk postal worker that reliably delivers all data packets - the modern internet is evolving to a massive distributed control tool with heavy political/social/societal consequences that will be able to spy, change or deny data packets as it sees fit. It might sometimes allow the packets through unchanged - but that could be a rarity!
What to do about IMP/CCDP part Two? Things to do:
★Data Canaries: 'I have received no IMP/CCDP warrant'
★a working SSL - CA system that is really trustable (sorry GCHQ)
★Signed webpages, all webpages (BBC News to Eastenders.co.uk) the IMP/CCDP will be trivially able to CHANGE the content of any requested webpage transparently and in real time. Maggie might not be yet dead in some future NORK-UK undemocracy.... all news & web-content needs to be trustfully signed and live verified at no cost to the user
★random data generators, random traffic flows, leave your PC browsing on its own whilst you go to the park
introduce some plausible deniability into traffic and data-patterns
this hopefully should keep the average person safe in the UK for the next 20 years
