The FTC singled out software vendor DesignerWare LLC because software it supplied for rented computers to secretly monitored renters' online activities, including user names and passwords for social-networking sites and financial institutions, medical records and photos of family members, sending the information to an email account designated by each store. The proposed FTC settlement with DesignerWare and the computer rental companies bars use of the monitoring software and prohibits use of geolocation tracking without consumer notice and consent.
