摘要
The present invention relates to a method and a device adapted to determine at a party whether a set comprising at least one user pseudonym is associated with a user, wherein each of the user pseudonyms in the set is associated with the user at a service portal. At the party, for each of the user pseudonyms comprised in the set, a publicly available first coded string associated with the user pseudonym is retrieved from the service portal associated with the user pseudonym, wherein each of the first coded strings has been generated on the basis of a first secret unique to said first coded string. The user's knowledge of the first secrets associated with the respective first coded strings is verified by means of a first cryptographic protocol for interacting with the user, wherein the first protocol is adapted to utilize the first coded strings.
