An article in Bloombergbusinessweek (Dec 19, 2011) describes the use of security camera video data to track consumer flows within Montblanc’s retil stores, with software by Retailnet enabling adjustments that increased sales 20 %. Given that individual tracking of customer movement can enable retailers to more carefully tarrget customers,  and retailer costs thus decrease, the remaining issue is whether it respects consumer privacy. Who owns the video data collected by retailer security cameras in the store and can retailers use that data to decrease their costs ? What regulations should be enforced or created to guarantee consumer privacy ? Should camera data be permitted to extract gender, age and nationality data to correlate with sales success ?
