How is the verification of the authenticity of the vote when using SMS?

Question

Information Security

Good afternoon

Please tell me how is the security assessment of the system that counts votes during SMS voting? There can be several participants of different (companies) in the system. What needs to be checked and controlled to be sure that all votes will be taken into account, processed and counted correctly?

Thank you in advance for your attention

Answer 1

store logs from the server processing incoming sms (usually they do not lie), then parse them and compare them with the database. here you have to analyze.
