The father of murdered nightclub hostess Lucie Blackman has unveiled a charity in his daughter's name.
Mr Blackman came up with the idea while searching for his daughter
The 21-year-old from Kent was killed in Japan in 2000.
Tim Blackman, who lives on the Isle of Wight, launched the charity at a concert at the Corinthian Yacht Club in Cowes on Friday evening.
The Lucie Blackman Trust will aim to promote measures which help those abroad get in contact with people back home, including a safety text scheme.
Tim Blackman came up with the idea for Safetytext while searching for his daughter.
Users create a message detailing their travel plans and set a time delay of between 30 minutes and 24 hours.
If they have not returned and cancelled the message by the deadline, it is sent to a chosen friend or relative.
He told the BBC News Website that the new trust would look at different ways of using technology to enhance safety for adults and young people.
"Since we launched the safety text service, colleges and youth groups have been saying they're really interested in these sorts of systems.
"The Lucie Blackman name has a resonance with people - we hope this will become a 'one-stop shop' for people wanting safety information like this."
