Abstract
To ensure the data corresponding to transactions has not been altered, a method and system are provided for generating secure endorsed transactions having transaction data representative of transactions and unique identifiers corresponding to parties endorsing the transactions. After receiving input, including transaction data and unique identifiers, unique codes are generated from the transaction data and unique identifiers. The unique codes constitute secure endorsements of the transaction data by the parties corresponding to the unique identifiers.
Claims8
A secure endorsed transaction system, comprising:
- an encoder that generates a unique code from input data comprising transaction data, a human identifier that uniquely identifies a human being, and a second key of an asymetrical key pair that includes the second key and a corresponding first key;
- a digital signature processor that generates a digital signature by encrypting the unique code using the first key;
- a formatter that formats a secure endorsed transaction using the digital signature and the input data;
- and
- a verifier that verifies integrity of the secure endorsed transaction by, as a function of the secure endorsed transaction, comparing a stored unique code derived by decrypting the digital signature using the second key with a computed unique code derived from the second key, the human identifier, and the transaction data.
