In the past 8 years, domestic violence in South Korea has increased by 718%. But only 2% are reported to the police. The reason behind this is that victims are unable to speak because they are in the same space as their abuser. So how can the police help a victim that cannot talk?

Inspired by Morse code, we created a solution to allow victims in danger to alert the police without saying a word. After dialing 112, they simply tap any number twice, and a link is sent to them. That allows the police to monitor the situation through the caller’s camera, track their location without an LBS request, and

secretly chat with them through an app disguised as a Google search page so that the perpetrator won’t notice. And the police can take immediate and precise action.

*112 is a South Korean emergency number, similar to 911

This new way of alerting the police was made known to the public through beauty channels, nail and hair salons, and other places frequented by women.

Furthermore, ‘Knock Knock’ also became a solution for the disadvantaged. For example, a deaf person in an emergency cannot simply make a phone call to the police, but with ‘Knock Knock’, they are able to protect themselves. Korean deaf actress So Byul Lee became an endorser of the campaign.

This new type of emergency call was introduced to 4,800 police call handlers nationwide. The campaign was introduced on the Korean government’s YouTube channel and their official blog, and widely publicized through OOH media at police stations and government offices nationwide.

After the campaign was launched, 5,749 links were sent to callers in emergency situations and ‘Knock Knock’ formally became an official emergency call in South Korea
