System and method for electronic certification and authentication of data

摘要

A system and method for authenticating data. Data may be received that is individually encrypted in a first encryption layer by each of a plurality of users using user-specific private keys. The received data may be encrypted together in a second encryption layer to create multi-layered encrypted data. The multi-layered encrypted data may be transferred to a beneficiary device to determine if the encrypted data is authentic. At the beneficiary device, the second encryption layer may be decrypted to expose the first encryption layer. Then, the first encryption layer may be decrypted using public keys that only decrypt data encrypted by private keys assigned to a plurality of authorizers pre-designated to authenticate the data. If the first encryption layer is properly decrypted using the authorizers' decryption keys, it may be determined that the users are the pre-designated authorizers.

1. A method for authenticating data, the method comprising:
receiving data individually encrypted in a first encryption layer by each of a plurality of users each user using a different user-specific private key, the data comprising a hash code for each user, each hash code generated based on at least the same document; encrypting the received individually encrypted data together in a second encryption layer to create multi-layered encrypted data wherein the second encryption layer is encrypted using an organization-specific private key uniquely assigned to an organization; and transferring the multi-layered encrypted data to a device that has an organization-specific public key for decrypting the second encryption layer and public keys that only decrypt data encrypted by private keys assigned to a plurality of pre-designated authorizers to determine if the users are the pre-designated authorizers.
