A method of transferring information between subscribers associated with a communication service is disclosed. The method includes receiving a first handle address associated with a first subscriber device, in which the first subscriber device transfers information to a group of subscriber devices, each of the group of subscriber devices is linked to different handle addresses, and each of the different handle addresses is included in a group of handle addresses. The method also includes determining whether the first handle address is included in the group of handle addresses, transferring information from the first subscriber device to the group of subscriber devices in response to the first handle address being included in the group of handle addresses, and verifying that the transferred information was received by the group of subscriber devices. A corresponding system and computer-readable device are also disclosed.

A method for verification of a data value via a Merkle root includes: storing, in a memory of a processing server, a Merkle root; receiving at least a data value, a nonce, and a plurality of hash path values; generating a combined value by combining the data value and the nonce; generating a first hash value via application of a hashing algorithm to the combined value; generating a subsequent hash value via application of the hashing algorithm to a combination of the first hash value and a first of the plurality of hash path values; repeating generation of the subsequent hash value using a combination of the next hash path value of the plurality of hash path values and the most recent subsequent hash value; and verifying the data value based on a comparison of the Merkle root and the last generated subsequent hash value.

The present invention provides a CCTV monitoring system for registering a camera and managing permission, and a control method of the system. In other words, according to the present invention, a manager having an installer terminal granted with temporal authority over the camera, can install the relevant camera, check whether the camera operates, and then, entrust/set authority over the camera to a terminal of an end-user through cooperation among the installer terminal, the terminal of the end-user, and a service server. Accordingly, convenience for a user can be improved and it is possible to more efficiently manage an installed camera.

The information processing apparatus stores a cryptographic module and a key that the cryptographic module generated. The information processing apparatus determines whether or not the stored key is a key that a cryptographic module for which integrity is not verified generated. If so, the information processing apparatus updates the key determined to be the key that the cryptographic module for which integrity is not verified generated.

A method of communication between a payload and a platform, including providing power to at least one payload via a platform, periodically sending an identification message from the at least one payload to the platform, decoding the identification message with the platform and sending a response message to the at least one payload, requesting access to one or more ethernet busses supplied by the platform, and enabling the one or more ethernet busses.

A method for performing initial registration is provided. The method includes receiving a server timeout message, the server timeout message including at least a field set to a value equal to a value received during a first registration. The method further includes initiating restoration procedures by performing an initial registration.

Systems, methods, and non-transitory computer-readable medium are disclosed includes for secure online credential authentication. One method includes receiving, over an electronic network, identification information from an identity provider; accessing, from a database, previously stored hashed identification information stored in association with a previous identity provider; comparing the identification information to previously stored hashed identification information; and storing the identification information in association with the identity provider that provided the identification information in the database when the hashed identification information does not match previously stored hashed identification information.

A system for storing and managing secure information is disclosed that includes a secure identity and profiling system, which serves as a middleman between a user and an entity requesting personally identifiable information (PII) from the user. The system collects the PII from the user and stores it securely, such as in an alternate blockchain in an encrypted form. The location of the that PII within the alternate blockchain may be indexed using smart contracts in a main blockchain that can only be read with an access token generated and supplied by the user's mobile device. When an entity requests PII from the user that has already been collected and securely stored, the user can provide permission to release that PII by providing the access token. The system will use the access token to locate where the PII is stored and release the PII to the requesting entity.

The invention relates to an electronic transaction method for a system comprising a user-associated payment device 3 or 4 and a payment terminal 1. The payment device 3 or 4 and the payment terminal 1 perform a cryptographic key exchange 500 before performing a transaction step 501. The payment device includes personal information PI about the user. The payment terminal includes a transaction policy including a condition relative to the personal information Pi. The method includes a verification step 510, 520, 530, prior to the transaction step 501, for securely verifying the condition of the transaction policy relative to the personal information using the cryptographic key.

A blockchain-based data processing method and apparatus, a computer device, and a computer-readable storage medium. The method includes: obtaining a data authorization request transmitted by an authorization terminal, the data authorization request including a data authorization certificate associated with an authorizer; performing authorization verification on the authorizer according to the data authorization request to obtain a first verification result; signing the data authorization certificate according to a private key of a first blockchain in a case that the first verification result is a valid result to obtain a first certificate signature, determining the first certificate signature as a to-be-uploaded signature, and performing uploading on the data authorization certificate carrying the to-be-uploaded signature; and transmitting the data authorization certificate to a second blockchain, and providing a query permission to a query terminal in a case that signature verification on the to-be-uploaded signature by the second blockchain succeeds.
