    摘要： A method is disclosed wherein an analog message signal is received with a finite length. An analog key signal is also received having a finite length at least as long as the analog message signal. An encryption carrier is generated ant then an encryption operation initiated to encrypt the analog message. First, the encryption carrier is modulated with the analog key signal, generating an encryption dynamic carrier. Then, the analog message signal is mixed with the encryption dynamic carrier, with the mixing process initiated at an initial key starting point of the analog key signal and an initial message starting point. An encrypted message signal is output from the mixing process, which encrypted message signal has a starting point that coincides with both the message starting point and the key starting point and an encrypted message end point coinciding with the encrypted message signal end point.

    摘要： A device may log update information associated with an operation, wherein the update information identifies one or more changes made to the dataset during the operation and a source of the operation. The device may identify, based on identification information associated with the dataset, a lineage record identifier associated with the dataset. The device may generate a lineage record associated with the operation, wherein the lineage record includes the lineage record identifier and the update information. The device may send a request for validation to an authorized node to validate the lineage record, wherein the authorized node is authorized to access the dataset. The device may store, based on the lineage record being validated by the authorized node, the lineage record in a distributed ledger, wherein the distributed ledger is accessible to a plurality of nodes to enable the plurality of nodes to access the update information.

    摘要： Data backup in a vehicle, where a datum is generated by a function implemented on a first control device of the vehicle. The securing of the datum generated is determined using the configuration data stored in a first control device. If the datum generated is to be protected, it is cryptographically marked and/or encrypted. The cryptographically marked and/or encrypted datum is stored in a memory of the first control device. In addition the cryptographically marked and/or encrypted datum or a value derived therefrom is sent over an electronic network of the vehicle to at least one second control device, received by the latter and stored in a memory of the second control device.

    摘要： The present invention is a platform and/or agnostic method and system operable to protect data, documents, devices, communications, and transactions. Embodiments of the present invention may be operable to authenticate users and may be operable with any client system. The method and system are operable to disburse unique portions of anonymous related information amongst multiple devices. These devices disburse unique portions of anonymous information and are utilized by the solution to protect sensitive data transmissions, and to authenticate users, data, documents, device and transactions. When used for authentication, login-related information is not stored in any portion of the solution, users and devices are anonymously authenticated. The solution also permits a user to access secured portions of the client system through a semi-autonomous process and without having to reveal the user's key.

    摘要： The invention is a process with operations or steps by which separate systems can communicate information and data through encrypted transmissions of data which may include strings, numbers, or other characters. This ensures that the messages are secure from eavesdropping and imitation by third parties. Security is further enhanced by using a method of reduced character sets to transmit data between systems by means of meta bits that allow single encrypted data items to represent multiple possible meanings. The receiving system uses these details to check the integrity of the data and sending system before decrypting the message. A similar method is used by the receiving system to encrypt its output before returning it to the original system. This results in a bi-directional encrypted messaging system that is impervious to outside attempts at decryption.
