The disclosed exemplary embodiments include computer-implemented systems, devices, and processes that securely manage transfers of digital assets between computing devices using permissioned distributed ledgers. By way of example, an apparatus may receive, from a first device, a request to transfer a digital asset to a second device and a first digital signature applied to the request. Based on a validation of the first digital signature, the apparatus may approve the request and apply a second digital signature to the request and the first digital signature indicative of the approval of the request by the apparatus. The apparatus may also transmit the request, the first digital signature, and the second digital signature to a computing system, which may validate the first and second digital signatures and perform operations that record the first public key and asset data identifying the digital asset within at least one element of a distributed ledger.

The present invention relates to an electronic voting system and an electronic voting method. The system for electronic voting includes an operation computer including at least one processor and a memory coupled to the processor, wherein the processor causes the system to: perform user authentication of voting participants who wish to participate in the online electronic voting; anonymize information of the voting participants whose the user authentication has been completed; give unique identification information to each of the voting participants who have completed anonymization process; and collect the voting information that the electronic voting has been conducted using the unique identification information given to the voting participants, and count the collected voting information as voting results.

A method is disclosed for authentic data transmission between control devices of a vehicle in which messages which are sent from a first control device to a receiver control device and are provided with a first cryptographic key for authentication, and messages that are sent from a second control device to the receiver control device are provided with a second cryptographic key for authentication. First status information provided with a third cryptographic key is sent from a monitoring module of the first control device to the receiver control device and second status information provided with the second cryptographic key is sent from the second control device to the receiver control device. The first status information and second status information are received by the receiver control device. The received first and second status information is evaluated to detect a manipulation of the first control device.

An example process includes breaking content into multiple fragments; and transmitting at least two of the multiple fragments over different physical channels in order to isolate the at least two fragments during transmission. The example process may include generating session keys; encrypting at least some of the fragments using different session keys; and associating, with each fragment, a session key used to encrypt a different fragment to produce fragment/session key pairs.

In some examples, in response to a request from a client device for information relating to a transaction stored by a blockchain, a system identifies, using information stored in a distributed storage system that stores data for the blockchain, multiple data owner entities from which permissions are to be obtained for access of the information, and determines an authorization requirement for the information based on a smart contract. The system sends authorization information based on the authorization requirement to trigger a retrieval of authorization tokens from the identified data owner entities for access of the information, and sends the information to the client device in response to receiving the authorization tokens.

Some embodiments of the invention provide a method for a trusted (or originator) device to modify the security state of a target device (e.g., unlocking the device) based on a securing ranging operation (e.g., determining a distance, proximity, etc.). The method of some embodiments exchanges messages as a part of a ranging operation in order to determine whether the trusted and target devices are within a specified range of each other before allowing the trusted device to modify the security state of the target device. In some embodiments, the messages are derived by both devices based on a shared secret and are used to verify the source of ranging signals used for the ranging operation. In some embodiments, the method is performed using multiple different frequency bands.

A system and method for facilitating secure transfer of encrypted files and/or messages can facilitate the secure transfer of encrypted files to a receiving user. The system can include: a computer program for facilitating sending of an e-mail message to a receiving user, the e-mail message including at least a web address of a trusted provider and instructions about how to securely download encrypted files without the receiving user setting up an account or a password, the transfer of encrypted files being facilitated by a code sent to a telephone of the receiving user.

A vehicle control device is provided. The vehicle control device includes a terminal device authentication unit that determines whether a terminal device of a user registered as a user of a vehicle, in advance, is present around or within the vehicle. The vehicle control device also includes a communication unit that communicates with the terminal device. Also included in the vehicle control device is a control unit that causes a display device provided in the vehicle to output a screen for setting communication between the communication unit and the terminal device. The display device outputs the screen in a case where it is determined by the terminal device authentication unit that the terminal device is present and the display device is started up.

An integrated circuit having Radio Frequency Identification components and circuitry used for authentication is discussed. The RFID components and circuitry include two or more coils and corresponding electrical circuits that are tuned to use two or more different resonant frequencies including: a first resonant RF used for power generation and a second resonant RF used for data communication. The integrated circuit contains a unique signature that is used for the authentication with two or more aspects including i) a first aspect that is a programmed password in a memory embedded on the integrated circuit, and ii) a second aspect that is a unique, randomly generated code based upon a physical characteristic of the integrated circuit.

A security solution having a system, a method, or a computer program for protecting contents in a target storage device that is arranged to be removable from a storage system having a unique combination of a system complex key (SCK) and a system identification (SID). The solution includes receiving a request to remove the target storage device from the storage system, where the storage system may have a plurality of storage devices each containing the identical combination of system complex key (SCK) and system identification (SID), and receiving a system complex key password (SCKP). The solution includes comparing the system complex key password (SCKP) to the system complex key (SCK) in the storage system, determining whether the system complex key password (SCKP) matches the system complex key (SCK) in the storage system, and suspending all read or write operations to the target storage device when the system complex key password (SCKP) matches the system complex key (SCK) in the storage system.
