Claim 12:
13. The system of claim 12, further comprising:
a second computer-readable storage medium comprising one or more programming instructions that, when executed, cause the public electronic device to:
receive the machine-readable image, and
cause the machine-readable image to be displayed on a display device of the public electronic device,

a third computer-readable storage medium comprising one or more programming instructions that, when executed, cause a user electronic device:
scan the machine-readable image to extract the key location identifier, the signed key location identifier and the first write token,
verify that the signed key location identifier is valid for a public key associated with the service,
combine a public key associated with the user and the first write token to generate a combination value,
sign the combination value to generate a signed combination value,
encrypt the signed combination value to generate an encrypted signed combination value, and
send 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.
