Claim 1:
2. The method of claim 1, further comprising:
by the public electronic device:
receiving the machine-readable image, and
causing the machine-readable image to be displayed on a display device of the public electronic device,

by a user electronic device:
scanning the machine-readable image to extract the signed key location identifier,
verifying that the signed key location identifier is valid for a public key associated with the service,

combining a public key associated with the user and the first write token to generate a combination value,
signing the combination value to generate a signed combination value,
encrypting the signed combination value to generate an encrypted signed combination value, and
sending the encrypted signed combination value, a second security token, a second read token, and a second key location identifier to the server electronic device, wherein the second security token and the second read token are generated by the electronic device and correspond to the user, wherein the second key location identifier uniquely identifies a second memory location of a data store associated with the server electronic device, wherein the first memory location and the second memory location are not the same.
