A system and process for converting a digital media file into a digital token is disclosed. The embodiments modify a digital media file so that a set of rules are attached to the digital media file creating a digital token, which can be used to persist the digital media file through a network. In an exemplary embodiment, the network is a distributed ledger or blockchain based network that securely tracks distribution of the digital media file. The digital token may have a value added to it or value may intrinsically exist as the digital token is persisted through the network. The value associated with distribution of the digital media file may be used to reward the owner of the digital media file, distributors of the token, or as an incentive program for commercial transactions and non-commercial transactions.

A method for generating device identifiers, including: receiving an identifier assignment request; in response to the received identifier assignment request, assigning a device identifier to a device, the device identifier being a unique identifier, wherein the device is to be assigned with the device identifier; and transmitting the device identifier to an identifier recording apparatus, wherein the identifier recording apparatus records the device identifier into the device.

This disclosure relates to blockchain-based copyright distribution. In one aspect, a method includes receiving, by a node device of a blockchain network, a target transaction including design data of a target work and an identity of a target copyright user corresponding to the target work. Design similarity comparison logic and copyright distribution logic are executed. The design data of the target work is compared with the design data of the existing work stored in the first smart contract to obtain a target similarity between the target work and the existing work. A copyright for the target work is distributed between the target copyright user and a copyright user corresponding to the existing work based on the target similarity. Copyright distribution data that specifies distribution of the copyright between the target copyright user and the copyright user corresponding to the existing work is stored in the first smart contract.

A method for providing an integrated service includes assigning a digital credential to a user account; receiving a request to schedule an integrated service in relation to the scheduled presentation of the digital content item; identifying, based on the digital credential assigned to the user account, the scheduled presentation of the digital content item; determining, based on the scheduled presentation of the digital content item, a set of available integrated services; providing, to the computing device, data identifying the set of available integrated services; receiving, from the computing device, a user selection of a first integrated service from the set of available integrated services; generating, based on data associated with the scheduled presentation of the digital content item, a service request to provide the first integrated service; and transmitting, to a remote server that provides the first integrated service, the service request to provide the first integrated service.

A Data Storage Device (DSD) includes a Non-Volatile Memory (NVM) including a private partition with a write-once partition only internally accessed by a controller of the DSD. Data stored in at least one memory of the controller and in the private partition is encrypted. According to one aspect, the NVM includes a firmware partition, and at least one key associated with the DSD stored in the write-once partition is descrambled or decrypted using a scrambler key or decryption key stored in the firmware partition. According to another aspect, a method for establishing a root of trust includes generating a scrambler key or a decryption key, and generating at least one key associated with the DSD. The scrambler key or the decryption key is stored in a firmware partition of an NVM of the DSD, and the at least one key associated with the DSD is stored in a write-once partition.

A method for protecting content, comprising receiving, from a client device, a request for an encryption key for encrypting the content comprising a reference associated with the client device, identifying a set of supported security capabilities corresponding to the reference associated with the client device, identifying a set of required security capabilities corresponding to the content associated with the key request, determining if the set of supported security capabilities satisfy the set of required security capabilities, and in response to determining that the supported security capabilities satisfy the set of required security capabilities, transmitting the encryption key to the client device.

A platform and method for content management is disclosed. A content right management method includes receiving contents from a user, and generating a create key for a right for the contents by encrypting the contents using encryption information, in which the create key includes a copyright of the contents and a creation right of the contents.

An information processing device not connected to a communication line includes a processor configured to measure an accumulated number of execution counts for specific processing repeatedly performed by an application, and perform control so that after the accumulated number of execution counts reaches an allowable number, the application is not started up.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain-based image processing are provided. One of the methods comprises: obtaining, by a computing device, copyright-related information corresponding to an original image; sending, by the computing device, the copyright-related information to one or more blockchain nodes configured to obtain ciphertext information by encrypting the copyright-related information and to store the ciphertext information in the blockchain; obtaining, by the computing device, the ciphertext information from the blockchain; and performing, by the computing device, obfuscation on a pixel matrix of the original image based on the ciphertext information to generate a target image carrying the copyright-related information.
