NOYB files TeleSign complaint over mass profiling of mobile phone users

23/06/2023 | NOYB

Austrian privacy group NOYB has filed a complaint against TeleSign, a US company that secretly profiles millions of mobile phone users. TeleSign generates"trust scores" between 0 - 300 and sell their services to customers such as TikTok, Microsoft, and Salesforce. The company verifies more than five billion unique phone numbers every month, half of the world’s mobile users.

The company receives the data from BICS, a Belgian company that provides interconnection services for mobile phone companies that enables phone calls, roaming, and data transfer across various networks and services globally.

NOYB honorary chairman Max Schrems said, “The responses received by BICS and TeleSign suggest that this business model is not complying with EU privacy laws. We have therefore filed a complaint with the Belgian Data Protection Authority, who is competent for Proximus, BICS and TeleSign.”
