The High Court in London has continued an injunction banning solicitation of information about the proposed identity and whereabouts of Maxine Carr.
Ms Carr, who was released from prison today, was convicted of conspiracy to pervert the course of justice during the Soham murder case in England.
Five newspaper groups had challenged the injunction, which could mean that her identity and movements are protected by the courts for the rest of her life.
Mr Justice Eady said it was necessary and proportionate to make the order upholding the injunction pending a full two-day hearing of the issues as soon as possible after 8 June.
Earlier at the hearing, the court was told that Ms Carr had received death threats.
In court, Ms Carr's lawyer said a number of specific threats had been made on her life, and that one mentioned 16 May.
Ms Carr was jailed for providing a false alibi for her boyfriend, Ian Huntley, after he had murdered 10-year-olds Holly Wells and Jessica Chapman in August 2002.
She served half of a 42-month sentence.
Earlier this week, it emerged that documents giving details of safe houses where Carr was to stay were stolen from a civil servant's car outside a North London pub.
The documents were later recovered following a police search.
