Anonymous telecommunication traffic measurement data associated user identifications

Kari Seppänen (Inventor)

Research output: PatentPatent


The invention allows anonymization of user identifications associated with telecommunication traffic measurement data that is fast, secure, and easy to use with distributed traffic measurements. Acquired user identification is input as an initialization vector to a block cipher. The block cipher is executed in cipher-block chaining mode to output a ciphertext. The output ciphertext is provided for use as an anonymized user identification in place of the user identification in further processing of the telecommunication traffic measurement data.
