Abstract
The invention discloses a fiscal data self-destruction system and an implementation method thereof. The system is constructed on the basis of fiscal equipment and a special encryption integrated chip (IC) and mainly comprises an abnormity detection circuit and a mechanical self-destruction device, wherein a timer and a general packet radio service (GPRS) network access port can be selectively arranged on the system. During protection of data, characteristic signals of conductive nodes are output to the abnormity detection circuit connected with the fiscal equipment in real time through a set of the conductive nodes on parts arranged in the fiscal equipment; when the characteristic signals are changed, the system determines that the fiscal equipment is illegally operated; and an enabling signal of the abnormity detection circuit drives the special encryption IC to clear away a key of fiscal data. By application of the technical scheme, manual operation is not required; the low-power-consumption encryption IC continuously detects states of the conductive nodes; the data destruction time is short, and the equipment upgrading cost is low; and furthermore, a distributed wireless monitoring network can be constructed through a GPRS network communication platform and interact with a fiscal background in real time, so that the processing efficiency is improved.

Embodiment
Following constipation closes the embodiment accompanying drawing, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.For solving prior art to the many defectives in the tax-control data security protection, the present invention has proposed a kind of technical scheme of data confidentiality protection of novel concept with innovating, adopts the mode of self-destruction key, provides tax-control data higher safety.
As shown in Figure 1, be the topological synoptic diagram of a kind of tax-control data destruct system of the present invention framework.Make up based on tax controlling equipment 1 and dedicated encrypted IC2 thereof from illustrating visible this system; Specifically it differs from the architectural feature of existing traditional tax controlling equipment: it has abnormal detection circuit 3; This circuit is the signal receiving circuit module based on dedicated encrypted IC2, is used for removing with the form driving dedicated encrypted IC2 of enable signal according to the variation that receives signal the key of the tax-control data of wherein being stored.Have mechanical self-desttruction equipment 4 simultaneously, be meant and be located at each parts 11,12,13 in the tax controlling equipment ... On the set of conductive node 4x, and each conductive node 4x self has characteristic signal, inserts mutually with abnormal detection circuit 3.With this device structure of realizing be: whole conductive nodes are uninterruptedly kept the characteristic signal of self and the physical change of interior each parts of corresponding device changes characteristic signal to the dedicated encrypted IC of device core feedback, and all system keys are stored and under the management and control of dedicated encrypted IC, read or destroy.
As the preferred version of technique scheme, this tax controlling equipment also comprise timer (not shown or GPRS network access interface (not shown) or have both concurrently, wherein timer is used for the time interval that timing dedicated encrypted IC removes the key of tax-control data; Said GPRS network access interface is used for the access distributed wireless detection networking of tax controlling equipment through GPRS network, and is mutual with tax background information.
Further, tax controlling equipment can external power supply or is had built-in power module, and the tax-control data destruct system is through external power supply or power module energy supply.Which kind of mode no matter, tax controlling equipment of the present invention all can provide the data security guarantee lastingly and effectively.Certainly preferred built-in power module for hand-held or portable tax control terminal device.
Again from tax-control data self-destruction implementation method of the present invention: this tax-control data refers to the confidential information that is only read by the key encryption and decryption the tax controlling equipment; It is characterized in that comprising: the step I; Through being arranged at the set of the conductive node on each parts in the tax controlling equipment, export the characteristic signal of conductive node in real time to the abnormal detection circuit that is attached thereto; The step II, after the characteristic signal of abnormal detection circuit reception conductive node changed, system was judged to be illegal operation, and the abnormal detection circuit enable signal drives the key that dedicated encrypted IC removes tax-control data.Wherein in the step I, one or more of each conductive node when tax controlling equipment receives unauthorised broken in the machinery self-desttruction equipment just can change by the occurrence characteristics signal, just can realize real-time monitoring thus, improves the ageing of equipment reaction.This scheme is merely a kind of preferable embodiment of self-destruction of the present invention, to not making the protection response through the intrusion of key authentication.
