Hi there,For users who don’t wish a service provider to be able to see their information, even ephemerally, and they would like to exchange information via BIP75, they can use a software wallet, such as a breadwallet or others, and that data will only exist on their phone, and the phone of their counterparty (assuming the counterparty also chose to exchange info, and was running on a software wallet).In this way, we allow users to exchange data as they choose, without having the risk that a service provider be asked for that data.If a user chooses to use a hosted platform, and also to store their identity data there, I do agree it could be subject to a subpoena, the same as when they host their email, and other services.Finally, they could choose not to use BIP75 at all, and no one would know whether they did or didn’t (other than their counterparts) as we don’t leave any residue on the blockchain, or anywhere else in the public eye.We believe that this solution, due in part to its narrow data aperture, is the best solution available to the problem we are solving. We are eager to engage in any discussions about how to improve the proposed solution, with an eye to fungibility, privacy, and usability.That said, there is a real need for people to know who they are transacting with for usability reasons, for fraud reduction, and also of regulatory reasons for some players. To NOT solve it with a carefully crafted standard means that it is more likely to be solved with back room, quick and dirty solutions that are not available for community review and feedback.Thanks!Justin--On Thu, Jun 23, 2016 at 2:31 PM, Police Terror via bitcoin-dev <bitcoin-dev@lists.linuxfoundation.org> wrote:In England under RIPA 2000 legislation, it's irrelevant whether you have

So any mechanism whereby data could be collected from Bitcoin users,
whether it's stored ephemerally or not, if the police have reasonable
suspicion to think it exists then they can compel all parties to work to
get them the data they require.
If the mechanism flat out does not exist, that is miles better than
could exist. Deniability is not a defense when served with a police
notice for disclosing data.
You have to think not only about the end result, but also about how
these mechanisms can be used for intimidating users or leveraging
technologies.
