‘EVM activist Hari Prasad is a hero, not a thief’

Best article ever on EVMs and Hari Krishna Prasad

What wrong has he committed? He is the general manager of a reputed firm in Hyderabad and has been an activist involved in this movement since the very beginning. He has the best interest of the country in mind. Consider that Hari Prasad has not entertained a single offer to tamper with an EVM from politicians. Politicians from the northeast offered lucrative sums to learn how to tamper with the EVMs but they were rejected. It is a matter of shame and travesty of justice that the Election Commission instead of appreciating the acts of such heroes should stoop to intimidation and try and punish them.

Hari Prasad’s actions are similar to those of activists in US and Europe and they are respected for it. For instance, Dr Alex Halderman who worked with Hari Prasad in hacking the Indian EVM has also hacked a EVM used in the US elections and he was employed by State of California Secretary of State to expose the vulnerabilities of the EVMs used in California.

Finally what did Mr. Hari Krishna Prasad get by trying to prove that Electronic Voting Machines are vulnerable to tampering?

A tag name called “thief” and investigation by IB (Intelligence Bureau) and RAW (Research and Analysis Wing, India’s secret intelligence service)

It makes clear in the minds of common people that all the charges are clearly orchestrated. Central Government is opposing his suggestions because they are under the purview that Mr. Hari Krishna Prasad is raising his voice against them, which is a fallacy.  Whereas Mr. Hari Krishna Prasad is trying to prove that the Electronic Voting Machines have many loopholes through which they can be tampered.  His campaign is not against any particular party or government.  As a responsible citizen of India, he want to make sure that the Indian Democracy is free and fair, and nobody is taking undue advantage of the loopholes.

To support Hari Krishna Prasad, raise your voice by voting here and at indianevm.com:

I request all the technologists and responsible citizens of India to join their voice together for the release of Mr. Hari Krishna Prasad and make the Election Commission implement his suggestions for a better democracy.

If any further pressure is put on Hari Krishna Prasad, this would directly imply that the ruling government doesn’t want the machines be rectified out of loopholes or they are trying the suppress the voice of genuine researchers working for the betterment of our nation.

Is arrest an answer for common citizen in India?

Is arrest an answer for common citizen in India for raising his voice against the vulnerability of our democracy for tampering, through Electronic Voting Machines (EVMs)?

Is this what responsible technologists get for using their skills for a better nation?

Raise your voice by supporting this concern:

Yes, in India arrest is the only answer if you are a normal citizen and if you raise your voice against any vulnerability, which challenges the politically backed bureaucratic system.

Mr. Hari Krishna Prasad, an ordinary technologist from Hyderabad was arrested on Saturday morning from his home for demonstrating the vulnerability of EVMs to tampering.

Mr. Hari Krishna Prasad with Dr. J. Alex Halderman, a professor of computer science at the University of Michigan and Mr.Rop Gonggrijp, a technology activist from Holland, conducted a thorough research on the vulnerabilities of Indian Voting Machines to tampering.  The team was successful in establishing multiple techniques to hack or tamper our Indian Electronic Voting Machines, which we use in all our elections.  These voting machines play a crucial role in deciding which government is formed.  If these machines can be tampered, are we assured that the vote we cast, is cast for the right government in the world’s largest democracy?

I request all the citizens of India and activists from the world to raise their voice against the arrest of Mr. Hari Krishna Prasad and promote a tamper proof democracy.

Let us not go back on technology; let us make it accountable through:

Electronic Voting Machine (Open Source) + Paper Receipt = Safe Democracy

Research Paper and Video:


This paper authored by Mr.Hari Krishna Prasad, Dr. J.Alex Halderman and Mr.Rop Gonggrijp, has topped the list of papers submitted at 17th ACM Conference on Computers and Communications Security.  Industry leaders like Microsoft Research, Google, IBM Research, US Army Research Office and Others back this program.
