Chennai sources stated that FASTags that are soon going to be mandatory for all vehicles passing through National Highway toll booths pose a data privacy threat to the vehicle owners. It can also be a serious security threat for women owners. Meanwhile FASTag is no more an option for vehicle owners but a mandatory requirement. But fennel Aurora, Security Advisor at F-Secure, a Finnish cyber security company said with FASTags it is possible to access the ownership and other data pertaining to the owner and it will be easy for tracking a vehicle not just by government agencies and other stakeholders of the system, but for private persons as well since RFID readers are easily available in the market at very low cost.

Furthermore he said for women owners, there is an additional threat. If the name/gender of the vehicle owner is available, this can be a significant risk for women who can be more easily tracked and targeted by violent men waiting near identified cars. Farrhad Acidwalla, Founder, Cybernetiv wallet PLATFORM' target='_blank' title='digital-Latest Updates, Photos, Videos are a click away, CLICK NOW'>digital said “The tag is primarily a unique signature and the data is out there. Being a privacy enthusiast, it is my top most priority to ensure that my data remains protected. FAS-Tag should be an option and not forced upon individuals”.

According to sunil Sharma, Managing Director–Sales, india & SAARC, Sophos, all the software systems can be breached and FASTags also carry the cyber security threats that any software system carries and further given the widespread security, privacy, safety, and corruption issues around the aadhar system, there are obvious reasons to doubt this new system also. Like many similar convenience measures that come with built-in surveillance, one has to wonder whether the few seconds saved is worth the potentially extreme costs.
