A method, system, and devices are provided in which modified digital signatures are used to provide a dynamically generated number suitable for use in transactions requiring validation. The method uses symmetric key encryption to encode a message comprising authorization information and may use compression algorithms to provide a truncated message digest such that the dynamic number may be processed by existing credit card or other authorization systems. In part, this method is an improvement over other validation methods as decryption, which requires greater computing power, is not required. The method may be performed through the use of various devices. For example, credit cards may utilize the method to dispose the dynamic number in a magnetic strip or to transmit the dynamic number via radio transmitter. Smart cards, smart phones, or USB devices, optionally may be utilized to perform the inventive method.

ENCRYPTION AND DECRYPTION TECHNIQUES USING SHUFFLE FUNCTION

Номер: US20190007390A1
Автор: Nathan Richard J., Tredennick Harry Leslie, Wu Paul Ying-Fung
Принадлежит:

Encryption and decryption techniques based on one or more transposition vectors. A secret key is used to generate vectors that describe permutation (or repositioning) of characters within a segment length equal to a length of the transposition vector. The transposition vector is then inherited by the encryption process, which shifts characters and encrypts those characters using a variety of encryption processes, all completely reversible. In one embodiment, one or more auxiliary keys, transmitted as clear text header values, are used as initial values to vary the transposition vectors generated from the secret key, e.g., from encryption-to-encryption. Any number of rounds of encryption can be applied, each having associated headers used to “detokenize” encryption data and perform rounds to decryption to recover the original data (or parent token information). Format preserving encryption (FPE) techniques are also provided with application to, e.g., payment processing. 1. (canceled)2. A computer-implemented method comprising:receiving a sequence of characters;performing one of encrypting of or decrypting of the sequence of characters, to generate an output; andperforming at least one hardware-based function from the group of storing the output in digital memory, using a transmitter to digitally transmit the output via a network to a destination, and using a display device to optically transmit a representation of the output to a destination; retrieving a key from digital memory,', 'using the key to hash an operand to generate a hash output, the hash output comprising a sequence of numerical values, and', 'assigning a sort order to the numerical values of the hash output, wherein a relationship between an initial position of each of the numerical values within the sequence of the hash output and a position within the sort order defines the transposition vector;, 'wherein said computer-implemented method further comprises using at least one processor to generate at ...

Decisional Architectures in Blockchain Environments

Номер: US20220020001A1
Автор: Snow Paul
Принадлежит: Inveniam Capital Partners, Inc.

Digital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a table identifier in a blockchain. Because there may be many digital contracts offered as virtual services, the table identifier uniquely identifies a particular decision table and/or the digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the decision table and/or the digital contract. The blockchain need only include or specify the table identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements. 1. A method performed by a server outsourcing a cloud-based contractual service , the method comprising:receiving, by the server, a contract identifier specified by a blockchain associated with a digital contract;receiving, by the server, a contractual parameter specified by the blockchain associated with the digital contract;identifying, by the server, a subcontractor's Internet protocol address by querying an electronic database that associates the contract identifier specified by the blockchain to the subcontractor's Internet protocol address;identifying, by the server, a table identifier by querying the electronic database that also associates the contract identifier specified by the blockchain to the table identifier;sending, by the server, a service request specifying the table identifier to the subcontractor's Internet protocol address and requesting the cloud-based contractual service based on the contractual parameter specified by the blockchain and a decision table referenced by the table identifier; andgenerating, by the server, a data record in a blockchain data layer describing the service request sent to the subcontractor's Internet protocol address requesting the cloud-based contractual service based on the ...
