Plans for a database containing information on every child in England would be dropped by a Conservative government, the party will announce at its annual conference tomorrow.
Labelling the £224m national Contactpoint database "dangerous", the party said it wants to "protect vulnerable children" by removing the risk of sensitive data being lost. It is proposing to put the data on smaller, local databases that are targeted at children considered to be at risk.
Contactpoint is due to be launched next year and will hold the names, ages and addresses of 11 million children, as well as the names of their GPs, parents and schools. The information will be available to workers in the health, social care and education sectors.
The announcement will be made by Michael Gove, shadow secretary of state for schools.
He said, "We are taking this action because we are determined to protect vulnerable children from abuse. Contactpoint would increase that risk.
"The government has proved that it cannot be trusted to set up large databases and cannot promise that inappropriate people would not be able to access the database. It would be irresponsible to implement something that is such a danger to our children."
At-risk children moving across local authority boundaries would be traced via the professionals at their previous address, he said.
