Overview:Overview:Parliament – to introduce lawful access BillDesign, operation and costing of almost all

‘public’ networks will be impacted (wire-line, wireless and Internet)

Future - network architecture, applications and services must be ‘access compliant’

“Access” = handover by Telecom. Service Provider (TSP) of specified Subscriber-related data to Law Enforcement Agencies (LEAs) upon lawful demand

Page 3: Waiting for the “Access” Axe to Fall: New Investigatory Assistance Legislation for Canada PST-2005 St Andrews, NB David A Townsend UNB-Law & NRC-IIT 12

Many challenges:Many challenges: Technical, Legal and Social challenges:

1) Done lawfully (Charter, Crim. Code, evidence law, privacy law and international obligations)

2) Does not undermine public trust (appropriate judicial oversight and public accountability)

3) Does not inhibit public networks (competitive forces, cost structures, rollout of new technologies and services, cust. relationship)

4) Done in technology-neutral manner (strive for uniform ‘expectation of privacy’ for all e-communication – inc. e-mail and SMS)

5) Need laws based upon first principles and not a legislative extension from common carrier era

6) Significant period for training and adjustment

Current Legislation:Current Legislation:

1974 Crim. Code wiretaps (Protect Privacy)1993 Code amended (s21 of CSIS in 1984)

– Search warrants s.487. (1)– General investigative warrants s.487.01– Suspect tracking warrants s.492.1– Dig. Number Recorder (DNR) warrants s.492.2– Production of telephone records s.492.2(2)

– Interception (wiretap) warrants s.186 and ss. 184.2(3), 184.3(6) and 188.(2)

Current Leg. Con’t.Current Leg. Con’t.– Assistance Orders (for all 6 warrants) s.487.02

2004 – 2 new Production Orders s. 487.012 & 487.013 (general and specific info.)

Code attempted to match intrusiveness with quantum of evidence necessary for judge

Charter case law of 1990s offered good check on state surveillance powers & activities

But, Code is 13 ‘telecom years’ out of date ! And, Code not address methodology, cost

recovery or lack of network capacity

Network Capacity & Network Capacity & Methodology for CellularMethodology for Cellular

Analog cellular introduced 1985– Fairly easy to intercept (scanners, UHF tuners) – Gov’t had low expectations of privacy

Digital (PCS) cellular introduced 1995– Interception difficult - encoding and encryption – FBI pressed Canada to add intercept requirements– 23 distinct requirements added as licence conditions

under Radiocommunication Act (done quietly)– Similar conditions in USA, New Zealand & Australia

What do LEAs want ?What do LEAs want ? General investigatory information:

– Subcriber name, address, phone number, local service provider (LSPID)

– LEAs pressed for national database, paid for by subscribers, available to LEAs w/o a warrant

Targeted investigations:– Subcriber name, address, phone number, device number

(e.g. ESN), service provider (LSPID), dynamic IP addr.– Best available location-based information– Detailed network transaction data– For wiretap – 100% of transaction data, location data

and communication content– Immediate preservation of specified data

Page 8: Waiting for the “Access” Axe to Fall: New Investigatory Assistance Legislation for Canada PST-2005 St Andrews, NB David A Townsend UNB-Law & NRC-IIT 12

Implications of Subscriber DBImplications of Subscriber DB

National Subscriber Data Base – very onerous and expensive for telecom

industry– Thwart anonymous use of telcom. (pay-as-you-

go, calling cards, anonymous e-mail, blogging)– Warrantless access by LEAs undermines

current privacy protections for subscriber info.– Subscriber Data Base facilitates data-matching

and data mining (including profiling)

Page 9: Waiting for the “Access” Axe to Fall: New Investigatory Assistance Legislation for Canada PST-2005 St Andrews, NB David A Townsend UNB-Law & NRC-IIT 12

Location Implications:Location Implications:

Location-based Information:– Location data will become increasingly precise

(tracking in real time or historic track)– Precision tells much about what target is doing– Technology no longer an assist to physical

surveillance– What evidential burden must be met to secure

relevant tracking warrant from a judge?– What use in civil cases?

IP Data Challenges:IP Data Challenges:

Many IP data challenges:– For 100% of transaction, location and content

data the Service Provider must isolate, preserve and hand-over mass quantities of targeted data

– Isolation, processing and preservation by TSPs raises significant forensic evidence issues

– Intercept warrants often sought against number of targets = storage capacity challenges for TSP

Page 11: Waiting for the “Access” Axe to Fall: New Investigatory Assistance Legislation for Canada PST-2005 St Andrews, NB David A Townsend UNB-Law & NRC-IIT 12

IP Data Challenges – con’t:IP Data Challenges – con’t:Warrants for Transaction Data (only):

– No parallel to historic ‘DNR Order’– IP transactional data may include: the dialling,

routing, addressing, signaling information that may provide the origin, direction, timing, duration, type and size of a e-communication.

– For e-mail and web surfing the transactional data may provide everything but the content

– But…the content may be unnecessary– What evidential burden must be met by LEAs?

Path to ‘Access’ Legislation:Path to ‘Access’ Legislation:Federal gov’t commissioned background

studies in 2000-2001August 2002 - release of “Lawful Access

Consultation Document” – Significant criticism = lack of justification and

specifics, failure to understand technologyComment period extended to mid

December 2002Over 300 submissions tendered

Page 13: Waiting for the “Access” Axe to Fall: New Investigatory Assistance Legislation for Canada PST-2005 St Andrews, NB David A Townsend UNB-Law & NRC-IIT 12

On the Path in 2003-04On the Path in 2003-04

Series of public and private consultations followed Spring 2003 gov’t introduced Bill C-46 (now Bill

C-13). (s.487.012 and s.487.013)– Bill C-13 (passed March 22.04) added a general and

specific data ‘production order’ to Crim. Code for investigation of serious corporate fraud. Came into force in September 2004.

Also in Spring 2003 gov’t introduced Bill C-32 (now Bill C-14).)– Bill C-14 (passed April 21.04) provided a new

exception in Code to unlawful interception for managers of computer systems who intercept to protect their networks
