Movable storage device and method for safely transferring tax-controlled data

Abstract

The invention relates to a method for safely transferring tax-controlled data. A movable storage device comprises a shell and a power unit, wherein the shell is internally provided with a communication unit, a storage unit and a processing unit; the communication unit is used for data exchanging of a first data receiving-sending system or a second data receiving-sending system and data exchanging of functional units in the shell; the storage unit is used for storing tax-controlled data; and the processing unit is used for validating the validity of the first data receiving-sending system or the second data receiving-sending system combined with the processing unit, processing obtained tax-controlled data, respectively storing one part of the tax-controlled data in the processing unit and transferring the other part of the tax-controlled data to the storage unit. The method of the invention can solve the tax-controlled data transfer problems which puzzle the enterprise and taxation bureau at present, reduce redundant time consumption, meanwhile seal all the tax-controlled data, and avoid the exposed tax-controlled data leakage or data tampering.

Description

Technical field [0001] The invention relates to a method for realizing the safe transfer of data, and in particular to a method for realizing the safe transfer of tax control data. Background technique [0002] In the field of tax collection and management in my country, especially for tax collection and management for general taxpayers and enterprises, a large number of anti-counterfeiting tax control systems composed of computer software and hardware are used. These anti-counterfeiting tax control systems are distributed in tax bureaus and tax bureaus in various provinces, cities, and regions. enterprise. The main function of the anti-counterfeiting tax control system is to prevent the forgery of invoices and the forgery of corporate income and expenditure information. [0003] The anti-counterfeiting tax control system installed in the enterprise is responsible for issuing invoices and recording the corresponding tax control data. When reporting taxes to the tax bureau at the s...

AI Technical Summary

Problems solved by technology

[0012] The storage device used for transferring tax control data has the coexistence of IC card and ordinary storage device, because limited by the current level of IC card manufacturing technology, the capacity of IC card cannot accommodate the tax control data generated by the enterprise tax control system

[0013] The part of the tax control data that is not transmitted by the IC card has manual access to the tax control data during the operation process, and the transfer process is stored in an ordinary storage device, so the security and accuracy of the tax control data cannot be guaranteed

[0014] In order to ensure the safety and accuracy of tax control data, some tax bureaus have required enterprises in the jurisdiction to use IC cards to transfer tax control data between the tax bureau and the enterprise many times, just like ants moving house. I went three times a week and more than a dozen times a month, which seriously affected normal work. This approach was strongly opposed by the company because it was unfeasible.
