  • Publication number: 20060106799
    Abstract: The invention relates to a method, a system, telecommunication servers and a network node for storing sensitive information such that they are easily retrievable when needed for instance using an identity number without extra identifiers, but stored such that they cannot be associated with an individual. The invention is based on the use of an internal identifier and two separate databases such that upon reception of a storage request (700) including data to be stored and the first identifier for identifying the individual with whom the data to be stored is associated, then a second identifier is generated such that its value does not depend on the first identifier; the first identifier and the second identifier are stored in the first database by binding the first identifier to the second identifier; and the data to be stored is stored in the second database together with the second identifier.
