Blockchain id connect

A method, comprising:

• receiving, at a federation service and from a user device associated with a user, a secure envelope, the secure envelope encrypted with a public key of the federation service and including (a) a federation service certification, (b) a self-certification, (c) a pointer to a first copy of a federation service hashed federation service certification, the first copy of the federation service hashed federation service certification previously generated by hashing the federation service certification using a first hashing technique and previously stored in a public storage facility by the federation service, and (d) a pointer to a user device hashed self-certification, the user device hashed self-certification previously stored in the public storage facility by the user device and generated by hashing the self-certification using a second hashing technique;
• decrypting the secure envelope using a private key of the federation service;
• retrieving the user device hashed self-certification from the public storage facility using the pointer to the user device hashed self-certification;
• retrieving the first copy of the federation service hashed federation service certification from the public storage facility using the pointer to the first copy of the federation service hashed federation service certification;
• hashing the federation service certification using the first hashing technique to generate a second copy of the federation service hashed federation service certification;
• hashing the self-certification using the second hashing technique to generate a federation service hashed self-certification;
• in response to verifying that (a) the federation service hashed self-certification matches the user device hashed self-certification, and (b) the first copy of the federation service hashed federation service certification matches the second copy of the federation service hashed federation service certification, sending a message to an entity to cause the entity to register a user profile associated with the user and in a database associated with the entity.

A method, comprising:

• hashing, at a user device associated with a user, a self-certification associated with the user using a first hashing technique to generate a self-certification hash;
• sending, to a public storage facility, the self-certification hash to cause the public storage facility to store the self-certification hash;
• receiving, from the public storage facility, a pointer to the self-certification hash;
• sending, to a federation service, a first secure envelope encrypted with a public key of the federation service, the first secure envelope including (a) the self-certification, and (b) the pointer to the self-certification hash;
• receiving, from the federation service, a federation service certification and a pointer to a federation service certification hash stored in the public storage facility by the federation service;
• sending a second secure envelope, encrypted with at least one of the public key of the federation service or a public key of an entity, to at least one of the federation service or the entity, the second secure envelope including the federation service certification, the self-certification, the pointer to the self-certification hash, and the pointer to the federation service certification hash;
• and
• receiving a confirmation indicating that a profile associated with the user has been registered in a database associated with the entity.

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the instructions comprising code to cause the processor to:

• receive, at a federation service and from a user device associated with a user, a secure envelope, the secure envelope encrypted with a public key of the federation service and including (a) a self-certification, (b) a federation service certification, (c) a pointer to a first data item associated with the self-certification, and (d) a pointer to a second data item associated with the federation service certification;
• decrypt the secure envelope using a private key of the federation service;
• retrieve, from the public storage facility, the first data item and the second data item using the pointer to the first data item and the pointer to the second data item;
• verify that the first data item corresponds to the self-certification and that the second data item corresponds to the federation service certification;
• and
• in response to verifying that the first data item corresponds to the self-certification and the second data item corresponds to the federation service certification, send a message to an entity to cause the entity to generate a profile associated with the user and in a database associated with the entity.
