Detailed Description
The present invention is further illustrated by the following examples, but it should not be construed that the scope of the above-described subject matter is limited to the following examples. Various substitutions and alterations can be made without departing from the technical idea of the invention and the scope of the invention is covered by the present invention according to the common technical knowledge and the conventional means in the field.
Example 1:
a method for providing random combined state code for commodity includes setting state code interface circuit module on commodity, said state code interface circuit module is formed from component A and component B.
The component A and the component B of the state coding interface circuit assembly comprise a specific combination surface formed by a conductive geometric figure. And the conductive geometric figures on the specific joint surface of the component A are respectively connected with an external interface circuit which needs to collect random combination state codes. When the specific joint surface of the component a and the specific joint surface of the component B are attached together, an external interface circuit which needs to acquire random combination state codes forms a conductive loop through the conductive geometric figure of the component a and the conductive geometric figure of the component B, so that a group of state codes are generated (namely, the geometric patterns on the joint surfaces of the component a and the component B are actually conductive circuits, and signals are output through the on-off relationship of the conductive circuits).
When A, B two parts are separated, the external interface circuit which needs to collect random combination state codes generates a set of initial state bit information through the conducting geometry of part A. When the specific combining surfaces of the A, B two components are jointed together, the conducting geometric patterns of the specific combining surfaces of the two components are combined randomly, so that the on-off state of a conducting loop formed by the conducting geometric figure of the component A by the external interface circuit needing to acquire the random combination state code is changed due to the influence of the conducting geometric figure of the component B to generate a group of specific state bit information. When A, B two parts are separated and bonded again, the patterns of the specific bonding surfaces of the two parts are bonded again randomly, so that the on-off state of the conductive loop is changed again, and a new group of state bit information is generated again.
In particular, such encoding methods may be used to distinguish between authenticity of goods. That is, when the article is packaged, components A, B are attached and their status bit information is generated and not changed until the article is sold (the use process may result in separation of components A, B). If the illegal person recovers the used package and manufactures the package into a new commodity again, the truth of the commodity can be reflected through the record of the state bit information.
Example 2:
similar to embodiment 1, this embodiment discloses a method for providing a random combination status code for a commodity, which includes a status code interface circuit module disposed on the commodity, where the status code interface circuit module is composed of a component a and a component B.
The component A and the component B of the state-coded interface circuit assembly comprise specific joint surfaces formed by conductive geometric figures. The conductive geometric figures on the specific combination surface of the component A are respectively connected with an external interface circuit which needs to collect random combination state codes. When the specific joint surface of the component a and the specific joint surface of the component B are attached together, an external interface circuit which needs to acquire random combination state codes forms a conductive loop through the conductive geometric figure of the component a and the conductive geometric figure of the component B, so that a group of state codes are generated (namely, the conductive geometric figures on the joint surfaces of the component a and the component B are actually conductive circuits, and signals are output through the on-off relationship of the conductive geometric figures).
When A, B the two components are separated, the external interface circuit that needs to collect the random combination status code generates an initial set of status bit information through the conductable geometry of component A. When the specific joint surfaces of the A, B two components are jointed together, the conductive geometric figures of the specific joint surfaces are combined randomly, so that the on-off state of a conductive loop formed by the external interface circuit needing to acquire the random combination state code through the conductive geometric figure of the component A is changed due to the influence of the conductive geometric figure of the component B to generate a group of specific state bit information. When A, B two parts are separated and bonded again, the conductive geometric figures of the specific bonding surfaces of the two parts are bonded again randomly, so that the on-off state of the conductive loop is changed again, and a new group of state bit information is generated again.
In particular, such encoding methods may be used to distinguish between authenticity of goods. That is, when the article is packaged, components A, B are attached and their status bit information is generated and not changed until the article is sold (the use process may result in separation of components A, B). If the illegal person recovers the used package and manufactures the package into a new commodity again, the truth of the commodity can be reflected through the record of the state bit information.

And the conductive geometric figure on the specific combination surface of the component A is connected with the interactive switch input port of the RFID chip. When the specific combination surface of the component A and the specific combination surface of the component B are attached together, the interactive switch input port of the RFID chip forms a conductive loop through the conductive geometric figure of the component A and the conductive geometric figure of the component B, and therefore a group of state codes are acquired.
When the two components are separated A, B, the interactive switch input port of the RFID chip generates an initial set of status bit information through the conductive path formed by the conductive geometry of component A itself. When specific joint surfaces of A, B two parts are jointed together, the conductive geometric patterns of the two specific joint surfaces are combined randomly, the conductive geometric pattern of the part B changes the on-off state of a conductive loop formed by the conductive geometric pattern of the part A, and the interactive switch input port of the RFID chip acquires a group of specific state bit information. When A, B two parts are separated and bonded again, the patterns of the specific bonding surfaces of the two parts are bonded again randomly, so that the on-off state of the conductive loop is changed again, and a new group of state bit information is generated again.
