<h2>Identification Friend or Foe</h2>

The objective is to provide Identity Friend or Foe information, while leaking as little individual identity information as possible – to identify oneself as a member of a group, for example employees entitled to access certain information, or guests entitled to access certain services, without flagging their specific individual identity far and wide.</p><p>

This outlines a scheme capable of being used for world domination and replacing everyone’s car keys, house keys, employee identification badge, and military dog tag, but before attempting that, we are going to start small by moving the corporate form to the blockchain, and putting your employee id in your crypto currency wallet, using it to escape dominion, rather than enforce it, a multiplicity of separate groups, rather than one enormous group. Then we conquer the world and enslave all the women, but our more modest initial target market is to support freedom of association, to put the corporate form on the blockchain.</p><p>

Any id scheme has potentially totalitarian uses, and I can easily imagine a whole lot of oppressive ways for using this scheme, but a scheme that links every interaction to one unique identity rooted in state documents, which is what we have now, is a lot more totalitarian than this proposal, because this proposal only shows you are fellow member of the group, or a person authorized to use a certain facility. Unlike the current system, it does not show which particular member of the group you are to all.

<h3>Large group IFF is constructed out of small group IFF</h3><p>
|
|||
|
|
|
|||
|
|
Each member of the small group has an infrequently changed secret key whose public key uniquely identifies him to a small number of other people, among them the leader of the small group (meaning the leader of the group’s computer. He has a frequently changing secret key, whose corresponding public key gets signed by the leader of the group’s less frequently changing secret key at frequent intervals. The list of frequently changing public keys identifying members of the group gets frequent signed updates from the leader which are sent out to all members of the small group, and members of the small group identify someone as a member of the group by checking to see if he is on the current or recent list.</p><p>
|
|||
|
|
|
|||
|
|
This is no good to members of an outgroup, which is a desirable feature, and no good to members of the larger group, which feature needs to be added.</p>

<h3>Large group IFF</h3><p>
|
|||
|
|
|
|||
|
|
The large group is a group of groups. The leader of each of small groups similarly has a frequently changing secret key, with which he signs each member’s frequently changing public key. To identify yourself as a member of the larger group, you sign your message with your frequently changing secret key, and show that your corresponding frequently changing public key was signed by someone on the list of frequently changing public keys of subgroup leaders within the larger group. Repeat for as deep a hierarchy as needed.</p><p>
|
|||
|
|
|
|||
|
|
If a member of the larger group misbehaves to another member of the larger group, the leader of the larger group can identify the subgroup that has a misbehaving member, and the leader of the subgroup can identify the particular member. For purposes of control, we may well, once we scale to embracing all of society, have a fairly deep hierarchy with a correspondingly small list of top level frequently changing keys, going all the way from king, to military officers and employers, to employees, to wives and children. </p><p>

This scheme inherently identifies you as a fellow member of a subgroup to another member of the same subgroup, but only identifies you as a member of the larger group to a member of the larger group who is not a member of your subgroup. We are going to start small (Hail fellow thought crime thinker, hail fellow black marketeer, hail fellow mafia member, hail fellow plotter, hail fellow employee of grey market block chain based business) but when we scale to embracing all of society someone is likely to be a member of multiple groups (reservist, employee, club member, family member) and will respond with the group of the pinger, if he is a member of that group as well. Your employee iff will unlock the door of your employer’s office building, and your family iff will unlock the door of your dad’s house.</p>

<h3>Fine grained control</h3><p>
|
|||
|
|
|
|||
|
|
The signature on the individual member’s frequently changing public key may contain additional information, above and beyond "friend", and he may receive several such signatures, each of which contains a different item of information. However, a basic ping should only reveal the information necessary.</p>
