The father of murdered bar hostess Lucie Blackman is to launch his safety text scheme in universities.
Mr Blackman hopes the scheme will keep new students safe
Tim Blackman, 52, from the Isle of Wight, came up with the idea for SafetyText while searching for his daughter who vanished in Japan in 2000.
Users create a message detailing their travel plans and set a delay of up to 24 hours. If they have not cancelled it by that time, it is sent to a relative.
Scheme details will be sent to students in Reading, Southampton and Dundee.
'Very worrying time'
The University of East Anglia (UEA) and Anglia Polytechnic University (APU) will also be sending the information out in freshers' packs.
Mr Blackman said: "It's a very worrying time for parents because it is very often the first time a child has moved away from home.
"We had universities getting in touch saying it's a very important system and they wanted to promote it to the students."
He said that 30,000 information cards had been sent out to the universities
Ms Blackman, 21, a former flight attendant from Sevenoaks, Kent, was working as a hostess in a nightclub in the Roppongi district of Tokyo when she was killed.
Businessman Joji Obara was arrested three months after Ms Blackman disappeared but it was not until February 2001 that police found her dismembered remains in a cave.
Mr Blackman has since visited Japan where Mr Obara is currently on trial charged with killing Ms Blackman and another foreign hostess and with raping six other women.
