A method for interworking data between a plurality of blockchain networks according to an embodiment of the inventive concept includes performing a first phase of a transaction by dividing steps of the transaction for recording data and performing a second phase of the transaction according to a result of performing the first phase, wherein performing the first phase comprises performing a first step of a first transaction for recording the data in a first blockchain network of a plurality of blockchain networks and requesting to perform a first step of a second transaction for recording the data in a second blockchain network of the plurality of blockchain networks. It may be available to interwork data between a plurality of blockchain networks without passing through a separate hub network, and ensure the concurrency of interworked data recording.

Method for associating data between a plurality of blockchain networks and apparatus thereof

A method for performing geomagnetic signal processing using a geomagnetic signal processing apparatus is provided. The method includes obtaining a geomagnetic signal based on a geomagnetic sensor output; converting the obtained geomagnetic signal into a high frequency signal having a frequency equal to or higher than a reference frequency using a signal processing filter; extracting abnormal high frequency signal values outside a predetermined critical range from the converted high frequency signal; determining whether a sum of the extracted abnormal high frequency signal values converges into a critical range a preset time window; and correcting the geomagnetic signal based on the determining.
