Spy agency halted bulk data searches after watchdog flagged concerns
OTTAWA — Canada’s spy agency sifted through large troves of data for information of value until a federal watchdog raised questions about a lack of guidelines for such searches, a new report reveals.
The Canadian Security Intelligence Service agreed to halt its acquisition of bulk datasets until it had a framework in place to govern the process of mining so-called “big data.”
In its annual report tabled Thursday, the Security Intelligence Review Committee said CSIS used datasets to identify previously unknown individuals of interest by linking together types of information that have indicated “threat behaviour.”
“They can be used to conduct indices checks by taking information already connected to a potential threat — such as an address, phone number or citizen identification number — and using it to search for ‘hits’ in the data,” the review committee report says.
