“trust is not the crucial thing, trustworthiness is the crucial thing”
if we return to our nascent trust chart, notice how by being a trustworthy TTP, we solve all potential pitfalls:
- Does the designer think / admit his system includes TTP?
- Does the user actually know about / trust those TTP?
- Is the designer’s trust well informed?
- Is the user’s trust well informed?
Yes, a trustworthy Trusted Third Party has all the features we want!
