Abstract: A hash contract is disclosed herein. A hash contract may be a value generated by a device using a hash function. The hash contract itself may represent a legally enforceable contract. The hash contract may be structured in a manner such that a device operated by a contracting party can transmit a legally enforceable contract over a network using a smaller file size than is possible with conventional secure transaction techniques. In addition, the manner in which the hash contract is generated allows a receiving device to verify that the contract elements of the contract are as expected and to verify an identity of a user that allegedly accepted the contract. Thus, even if a malicious user attempts to alter contract elements or perform other fraudulent activity, the receiving device can use the hash contract to identify such activity and prevent a transaction from being completed.

Abstract: An acceptance hash code is disclosed herein. An acceptance hash code is a value generated by a device using a hash function. The acceptance hash code itself may represent a legally enforceable document. The acceptance hash code may be structured in a manner such that a device operated by a user can transmit a legally enforceable document over a network using a smaller file size than is possible with conventional secure transaction techniques. In addition, the manner in which the acceptance hash code is generated allows a receiving device to verify that the document elements of the document are as expected and to verify an identity of a user that allegedly executed the document. Thus, even if a malicious user attempts to alter document elements or perform other fraudulent activity, the receiving device can use the acceptance hash code to identify such activity and prevent a transaction from being completed.
