A computer system comprises a plurality of service execution systems each configured to execute a service for implementing an application that executes a distributed transaction. At least one of the plurality of service execution systems is configured to generate determination information for determining whether rollback of the distributed transaction is required and to transmit the determination information to another one of the plurality of service execution systems, and the another one of the plurality of service execution systems that has received the determination information is configured to determine, through use of the determination information, whether the rollback of the distributed transaction is required.

The embodiment of the present application provides a security protection module, a communication device and a communication system; the security protection module comprises an active signal input end, a top metal, an XOR gate unit, an OR gate, a gate unit, a check unit and a register; the active signal input end is used for accessing communication data and transmitting the communication data to the top metal, the XOR gate unit and the gate unit in parallel; an output end of the top metal is connected with the XOR gate unit; two output ends of the XOR gate unit are connected with another input end of the gate unit and the OR gate respectively; the OR gate is used for outputting an attack mark indicating whether the top metal is damaged; the gate unit, the check unit and the register are connected in sequence, the gate unit is the XOR gate unit or the OR gate unit, and the register is used for outputting check data output by the check unit; when the attack mark indicates that the top metal is not damaged, if the output result of the gate unit is inconsistent with the communication data, it indicates that the top metal is damaged. Therefore, the communication security is improved.

A data storage device includes a plurality of sheets having faces marked with characters. An elongate core is configured such that a slot of a sheet can fit over an openable end of the core to mount the sheet on the core and in alignment with the marked face, and to slide along the core. The length of the core is sufficient to enable some sheets of a stack of mounted sheets to slide away from other sheets of the stack to form a gap sufficient to enable reading of the characters on the sheets. A locking element can be placed over the openable end to prevent removal of a sheet from the stack, and the locking element can be removed to enable addition or removal of a sheet. A housing can enclose over the core and include a restraining structure to restrain sliding of the sheets when the housing is enclosed.

Systems and methods of the present disclosure enable reversible blockchain operations. An operation-reverse operation pair specifies an operation for exchange of a first token for a second token, and a reverse operation for return of the second token for the first token upon at least one condition being satisfied. A self-executing software container (SESC) executes the operation-reverse operation pair according to the condition by detecting a transfer of the first token into a first segregated data structure, and a transfer of the second token from a second token storage to a first token storage. The SESC initiates a transfer of the first token from the first segregated data structure to a second segregated data structure in response to the transfer of the second token. Upon detecting a reverse operation matching the condition, the SESC initiates a transfer of the first token back to the first segregated data structure.

The invention discloses a government affair quantum chain private key distributed management system and management method, and relates to the crossing field of quantum information security and block chain technology, in particular to a government affair quantum chain private key distributed management system and management method. The system comprises a private key generation center, a plurality of distributed nodes, a multi-party consensus verification module and a real-time monitoring module which are connected through a quantum key distribution network. The private key generation center integrates four independent biological recognition devices to generate quantum private key seeds, and adopts a threshold scheme to divide a private key into a plurality of fragments and distribute the fragments to distributed nodes for secure storage. Any key operation needs at least four nodes to consensus and complete biological recognition authentication, and then a private key can be temporarily reconstructed. When abnormal access is detected by the real-time monitoring module, a physical fusing mechanism can be triggered at a millisecond level. According to the method, the management process is intelligently contracted, and high-security, high-availability and auditing distributed management of the quantum private key in the government affair environment is realized.

An electronic device for encoding image information, according to the present specification, comprises: a camera module including at least one lens configured to capture an image; and an optical element movably coupled to a front area of the at least one lens so that an object in the image is unidentifiably encoded.

A high throughput encryption and decryption system is provided that is equally applicable to data in transit as to data at rest. The data security device includes analog components and control circuitry that operate internally with a high degree of entropy. The high degree of entropy resides in interactions between components responsive to external driving signals that have a sufficiently high level of entropy that digital simulation of the analog components is impractical. In the data security device, a portion of the conversion between plaintext and ciphertext uses analog components. Because analog components are digitally unclonable, the portion of the conversion process that uses the analog components requires possession of the analog components themselves or another analog component with the same signature.

A processing method of a neural network is provided. An AI compiler source code of an artificial intelligence compiler is converted into a garbled circuit code, including the following steps: a server transmits a circuit diagram of a garbled circuit having a plurality of logic gates corresponding to the garbled circuit code to an electronic device; the electronic device generates a plurality of key codebooks corresponding to a plurality of candidate gates of each logic gate; the electronic device generates a plurality of garbled truth tables corresponding to the plurality of candidate gates of each logic gate and transmits them to the server by using a blinding transmission protocol; and the server obtains a target garbled truth table of each logic gate. Then, the electronic device encrypts a neural network model according to the plurality of key codebooks. The server generates a compiled neural network model of the encrypted neural network model.
