Disclosed are a method and apparatus for processing physiological signals. The method is inclusive of steps of obtaining the physiological signals; grouping the physiological signals based on their sampling frequencies and/or generation mechanisms, so as to acquire grouping results; and compressing, based on the grouping results, each group of physiological signals.

Method and apparatus for processing physiological signals and non-transitory computer-readable medium

Disclosed is a tampering detection method applied to one of multiple entities involved in a paper copy transfer process. The method includes steps of obtaining an optically readable copy of a paper copy; acquiring a verification code detection result of the optically readable copy; if the verification code detection result contains no verification code, then determining that the paper copy has been tampered with; and in a case where the verification code detection result contains a verification code and a print transaction ID associated with the verification code, attaining, based on the print transaction ID, a print transaction corresponding to the print transaction ID, and performing comparison on the optically readable copy and information contained in the print transaction so as to determine whether the paper copy has been tampered with. Each of the plural entities corresponds to a node in a distributed data network.

Tampering detection method and apparatus and non-transitory computer-readable storage medium

A method for managing a consortium chain data structure network, a management node, and a non-transitory computer-readable recording medium are provided. The consortium chain data structure network includes a first network that maintains a first chain data structure for recording management data, and a second network that maintains a second chain data structure for recording user data. A management node for management consensus of the consortium chain data structure network only accesses the first network. In the method, the management node receives a management request message sent by a requesting node, verifies the management request message, and processes the management request message in response to successful verification on the management request message. A data block in the first chain data structure is generated based on a result of the processing.
