Abstract: Electronic signatures are authenticated utilizing near field communication (NFC) devices as proof of identity. An identification service collects an identification of a NFC device associated with a signer of a contract. The identification may be utilized as an access control mechanism that enables the signer to receive, view, or sign the contract. An electronic signature associated with the signer is received. The identification of the NFC device and the electronic signature of the signer are recorded in the contract and/or audit information associated with the contract.

Abstract: Techniques are disclosed for providing an electronic signature service where the content of an electronic document to be signed remains unknown to the service. A sender of the electronic document negotiates a specification for encoding the electronic document. In particular, the specification does not include any content of the electronic document. In this manner, the content of the electronic document can be encrypted and securely transmitted between the sender and the signer via the electronic signature service using one or more data packets conforming to the specification without permitting the electronic signature service to read or otherwise decipher the content. The specification enables the electronic signature service to certify that the signer has received the electronic document and assented to its terms.
