The present invention relates to a method and system for managing an impersonated or forged/tampered email. To this end, the present invention provides a method and a system for managing an impersonated or forged/tampered email, the method comprising: a step in which, when an email is received at an email account of a recipient email server through a network, a system for managing an impersonated or forged/tampered email, positioned between the network and the recipient email server, generates verification request information including details of the received email and a sender email address and transmits same to the sender email address of the received email; a step in which, when the verification request information is provided, a sender email server of the sender email address checks if the sender email address included in the verification request information is valid, and returns an error code to the system for managing the impersonated or forged/tampered email when the sender mail address is not valid; and a step in which, when the error code is returned, system for managing the impersonated or forged/tampered email blocks the received email.

A method for securing network communication between containers by a terminal, includes: a step of installing an HSI (Hyperion Secure Interface) for communication with a secure bridge included in an NIC (Network Interface Chip) in a secure container through a manager module; a step of changing a source address of a transmission packet to a specific token on the basis of a map of the HSI through the manager module; a step of delivering the transmission packet to the secure bridge through the HSI; a step of determining whether the specific token of the transmission packet is valid; and a step of changing the specific token to the source address and delivering the transmission packet to a target container when the specific token is valid.

Disclosed are techniques and an apparatus for accessing a smart contract library that may include a number of templates of different legal contracts implementable as a smart contract between respective parties. Each template may include a number of sections having different contractual terms and conditions and fillable fields for specific contract terms. Each respective section of the number of sections includes programming code operable to enforce conformance with specific section-related contractual terms and conditions of the respective section and with any specific contract terms input to a fillable field of the respective section. A first user address generated based on cryptographic keys may be associated with a contract-creating computing device in a private blockchain. The first user address may be associated with the first user in the private blockchain. A finalized smart contract may have a smart contract address generated from the first user address and a nonce value.

Systems and methods for enabling collection of signed data in a collaborative content sharing platform. One embodiment is a method including producing a form having one or more data entry components and at least one signature block component, selecting assignee users of the content sharing platform, providing the form to the selected assignee users, enabling these users to enter data and sign the form, and storing the assignee users' data in a data structure which is separate from the form, where the data structure includes a record for each assignee user, the record containing data entered by the user and electronic signature data for the user. The data structure is protected in the same manner as other data in the collaborative content sharing platform and may be accessible by some users, but not others, in accordance with their respective roles and authorizations.

Methods, apparatus and computer readable code for determining whether a potential relay device is a relay device are provided herein. In some embodiments, first and second information elements are received from a potential relay device, which is an original source of the second information element. In order to determine whether the potential relay device is a relay device, it is determined whether a feature of an original source of the first information element and a feature of the potential relay device are features unlikely to relate to a single device, wherein a positive result of the determining is indicative that the potential relay device is a relay device. In an exemplary embodiment, a disclosed system includes an information element receiver and a feature incompatibility analyzer. Optionally, the disclosed system includes a feature discovery module, a parameter obtainer and a feature database.

A network node of a mobile communications network may need to generate at least one new Input Offset Value, IOV value, for use in protecting communications between the network node and a mobile station. The network node then associates a fresh counter value with the or each new IOV value; calculates a Message Authentication Code based on at least the at least one new IOV value, the fresh counter value associated with the or each new IOV value, and a constant indicating that the Message Authentication Code is calculated to protect the new IOV value; and transmits the at least one new IOV value, the fresh counter value associated with the or each new IOV value, and the calculated Message Authentication Code to the mobile station.

A transaction data processing method includes: receiving a first transaction document from a device of a transaction initiator, the first transaction document being associated with identity labels of a plurality of transaction participants; separately performing identity authentication on the plurality of transaction participants according to the identity labels of the plurality of transaction participants, to obtain an identity authentication result. The method also includes adding the identity authentication result into the first transaction document when the identity authentication results indicates identity authentication of each of the plurality of transaction participants is successful, to generate a second transaction document carrying the identity authentication result; separately transmitting a signature request for the second transaction document to devices of the plurality of transaction participants; and generating a third transaction document according to responses returned by the devices of the plurality of transaction participants in response to the signature request.

Techniques and screening messages based on tags in an automotive environment, such as, messages communicated via a communication bus, like the CAN bus. Messages can be tagged with either a binary or probabilistic tag indicating whether the message is fraudulent. ECUs coupled to the CAN bus can receive the messages and the message tags and can determine whether to fully consume the message based on the tag.

Some implementations of the disclosure are directed to a method, comprising: retrieving, using a device associated with an entity, a document from a system of record; uploading the document for storage in an off-chain system accessible by entities having access to a distributed ledger of a distributed ledger network, the entities comprising the entity; hashing, using the device, one or more fields contained in the document to generate a hash representing a unique reference to the document; generating, using the device, a message comprising a plurality of fields contained in the document and the hash; digitally signing, by the device, using a private key associated with the entity, the message to endorse the hash and the fields contained in the document; and after digitally signing the message, transmitting, by the device, the message to the distributed ledger network to store the hash and the fields in the distributed ledger.

A method for providing evidential data is described includes obtaining data items, generating a respective first hash value for each data item, generating a second hash value for a data set comprising the first hash values but excluding the one or more data items, obtaining one or more transaction identifiers including one or more static identifiers, generating a respective third hash value for each of the one or more static identifiers, transmitting a first message comprising the one or more data items, the one or more first hash values, the second hash value, and the one or more third hash values to a server.
