Israeli firm D-ID (de-identification) has built software that subtly alters stored pictures to escape detection by facial-recognition algorithms.The firm's software is designed to prevent companies using facial data without users' explicit permission.Profiled in Isreal21's “nine Israeli firms protecting our kids on social media”, the company founders told the magazine they were inspired by during a post-army trek to South America, when they weren't allowed to post pictures of themselves due to the sensitivity of their previous military positions.
