摘要： The present invention refers to a method for anonymization by transmitting an event data set from at least one data supplying entity supplying the event data set to at least one data aggregating entity aggregating the event data set wherein the data set includes at least one identifier identifying at least one user of the data supplying entity, the method comprises the steps of performing a non-reversible basic encryption of the at least one identifier using an encryption mechanism with a certain lifetime, iteratively performing an additional encryption of said basic encrypted identifier for n-times with n equal or greater than 1 resulting in an additional encrypted identifier, wherein the additional encryption comprises the steps of adding a random component to said encrypted identifier and encrypting the output using asymmetric encryption with a public key, wherein each iteration uses a random component with a lifetime shorter than the lifetime of the certain lifetime according to step a and than the lifetime of the previous iteration and a public key different to that of the previous iteration, transmitting the event data set characterized by the n-times additional encrypted identifier to the at least one data aggregating entity, and undoing at least one iteration of the additional encryption(s) at the at least one receiving data aggregating entity.

摘要： The invention relates to a method for transmitting a data set from at least one first entity supplying the data set to at least one second entity aggregating the data set wherein the data set includes at least one identifier identifying at least one user of the first entity. At a first step a first encryption of the at least one identifier on the basis of an encryption key which is only known to the first entity is performed to obtain a single-encrypted identifier. As a second step a number of random characters defining a character string is added to the single-encrypted identifier and afterwards an asymmetric key encryption is applied as a second encryption to obtain a double-encrypted identifier. The resulting double-encrypted identifier is transmitted to the at least one second entity.
