Abstract: A digital voucher system facilitates the convenient application of vouchers against products and services purchased from a merchant by a consumer. A voucher enabled device carried by the consumer stores digital vouchers in memory. The merchant queries and obtains applicable vouchers for the consumer from the voucher enabled device carried by the consumer, applies the vouchers to a transaction, and communicates the resulting transaction data back to the voucher enabled device.

Abstract: A data storage layer provides enhanced data security. In one implementation, the data storage layer allows selective encryption of specific parts of data blocks, with decryption restricted to pre-determined entities. The selective encryption may be applied to parts of data blocks that are stored in blockchains, for instance, to provide fine grained control over which entities with access to the blockchain can decrypt and use the parts of the data blocks with the enhanced security.

Abstract: Hardware acceleration supports complex software processes. In particular, a hardware security module provides encryption support for transaction chains. In one implementation, the security module circuitry provides high-speed security features and acceleration of the security features for blockchain processing.

Abstract: An electronic certificate system facilitates the secure application of certificates against wireless data transfers with a distributer system by a device user. A certificate enabled device carried by the user stores electronic certificates in memory. When the distributer system detects a certificate enabled device within a proximity radio frequency field, the distributer system queries and obtains applicable certificates for the user from the certificate enabled device carried by the user, applies the certificates to a data transfer, and securely communicates the resulting data transfer metadata back to the certificate enabled device.

Abstract: A digital voucher system facilitates the convenient application of vouchers against products and services purchased from a merchant by a consumer. A voucher enabled device carried by the consumer stores digital vouchers in memory. When the merchant detects a voucher enabled device nearby, the merchant queries and obtains applicable vouchers for the consumer from the voucher enabled device carried by the consumer, applies the vouchers to a transaction, and communicates the resulting transaction data back to the voucher enabled device.
