Patent ID: 8661260

Claim:
A method of indicating a trustworthiness of a received message, said method comprising: receiving, via a software program, a message comprising content that has been digitally signed by a digital signer with a digital signature; accessing a set of cryptographically secure attestations by a third party entity, the third party entity being known to software that received the message; successfully identifying a cryptographic key that was used to sign the message and an entity that holds the key, the successfully identifying comprising determining cryptographically secure bindings associated with the message, the cryptographically secure bindings being between said content, said message, and said digital signer, and between said digital signer and said third party entity; successfully verifying that the digital signature of the message is cryptographically associated with the identified cryptographic key; calculating, using one or more computer hardware processors, a set of indicia from the message and said cryptographically secure attestations; presenting said indicia to a user; and after the successfully identifying the cryptographic key and the successfully verifying that the digital signature of the message is cryptographically associated with the identified cryptographic key, requesting said user to modify the indicia that were calculated from the message.
