instagramInstagram has updated its terms and conditions to claim ownership of all photograph rights.

Newly announced changes to Instagram’s terms and conditions give the rights to all images uploaded. Moreover, it allows Instagram to use them for commercial purposes without identification.

According to Jeffrey Chester, executive director for the Center for Digital Democracy, that may let advertisers use teenagers’ photos for marketing, raising privacy and security concerns.

Instagram’s new policies, which now apply to users as young as 13, enable the site to use members’ names, text, photos and other content with marketing messages, will take effect next month. “It could be exploitative,” Chester added.
