I presented to the Financial Services Club meeting in Scotland last night and was asked an intriguing question at the end about anonymity. What are the issues around protection of privacy and, by contrast, the requirements to protect anonymity? If I am buying pornography, drugs or weapons online, am I doing this legally or illegally? Buying pornography is not an issue but what if it’s paedophile pornography? Buying drugs like Viagra may be no issue but what if it’s crack meth? Equally, I can buy guns online in some countries without issue, but what if it’s for arming a terrorist organisation?
