after adopting any one of the modes a or b:

Further, the state coding system with strong association according to the scheme 1, 2,3 or 4 is characterized in that: the method comprises the following two verification steps:

And (3) verifying:

verifying whether the component a to be verified and the component B to be verified which are combined together are the actual component a and the component B: the background system acquires information A to be verified of a part A to be verified and information B to be verified of a part B to be verified;

if the background system judges that the information A to be verified and the information B to be verified accord with the mapping rules of the non-empty set A and the non-empty set B, judging that the part A to be verified and the part B to be verified are real parts A and B;

If the background system determines that the information a to be verified and the information B to be verified do not conform to the mapping rules of the non-empty set a and the non-empty set B, then it is determined that at least one of the component a to be verified and the component B to be verified is counterfeit (for example, in the case of a "false lock", the component a and the component B are not actually attached, the counterfeiter makes the fake component B attached to the real component a or makes the fake component a attached to the real component B, and by using the above method, it can be determined that the counterfeit.

And II, verification:

When the component A and the component B are combined, the specific combination surface A and the specific combination surface B are closely contacted, a group of associated information A and information B are obtained, and the information A and the information B are marked as associated calibration information A and calibration information B;

When verifying the component A to be verified and the component B to be verified which are combined together: the background system acquires information A to be verified of a part A to be verified and information B to be verified of a part B to be verified; if the information A to be verified and the information B to be verified are not the associated calibration information A and the calibration information B (the information A to be verified is not the associated calibration information A and/or the information B to be verified is not the calibration information B), the components A and B are separated after the calibration information A and the calibration information B are judged to be formed. The term "once separated" includes the case where a "null lock" exists. The "empty lock" case refers to case 1 or case 2. Case 1: when the associated calibration information a and calibration information B are formed, the component a has been counterfeited (the counterfeited component a is the same as the authentic component a), and the counterfeited component a is combined with the authentic component B and forms the associated calibration information a and calibration information B. At the time of verification, the counterfeiter separates the counterfeit component a from the authentic component B, allowing the authentic component a to be combined with the authentic component B. (since the component A and the component B are attached when the calibration information is acquired, the two are separated and attached again, and the positions thereof are almost impossible to be the same, and therefore if the information A to be verified and the information B to be verified are the associated calibration information A and the calibration information B, it is determined that the component A is once separated or the above-mentioned "empty lock" after being mounted on the component B. If the information A to be verified and the information B to be verified are the associated calibration information A and the associated calibration information B, the components A and B are largely unseparated after the calibration information A and the calibration information B are judged to be formed.

Conductive contact a is located in the outer annular region, conductive contact b is located in the inner and outer annular regions, conductive contact c is located in the outer annular region, conductive contact d is located in the inner annular region, conductive contact e is located in the inner and outer annular regions, and conductive contact f is located in the inner annular region.

Example 13:

The main technical scheme of the embodiment is the same as that of any one of the above embodiments, and further, when in use, the method comprises one or two of the following two verifications:

And (3) verifying:

If the background system judges that the information A to be verified and the information B to be verified do not accord with the mapping rule of the non-empty set A and the non-empty set B, judging that at least one of the part A to be verified and the part B to be verified is forged.

And II, verification:

When verifying the component A to be verified and the component B to be verified which are combined together: the background system acquires information A to be verified of a part A to be verified and information B to be verified of a part B to be verified; if the information A to be verified is not the associated calibration information A and/or the information B to be verified is not the calibration information B, the components A and B are separated after the calibration information A and the calibration information B are judged to be formed. The "once separated" may include case 1 or case 2 in the actual scenario. Case 1: when the associated calibration information a and calibration information B are formed, the component a has been counterfeited (the counterfeited component a is the same as the authentic component a), and the counterfeited component a is combined with the authentic component B and forms the associated calibration information a and calibration information B. At the time of verification, the counterfeiter separates the counterfeit component a from the authentic component B, allowing the authentic component a to be combined with the authentic component B. (since the component A and the component B are attached when the calibration information is acquired, the two are separated and attached again, and the positions thereof are almost impossible to be the same, and therefore if the information A to be verified and the information B to be verified are the associated calibration information A and the calibration information B, it is determined that the component A is once separated or the above-mentioned "empty lock" after being mounted on the component B. If the information A to be verified and the information B to be verified are the associated calibration information A and the associated calibration information B, the components A and B are largely unseparated after the calibration information A and the calibration information B are judged to be formed.

Example 14:

the main solution of this embodiment is the same as embodiment 13, and a grounded solution (embodiment 3) is adopted, specifically, the component a has a specific bonding surface a (fig. 1). The component B has a specific bonding surface B (fig. 2).

The surface of the specific combination surface A is provided with 3 groups of conductive contacts symmetrical about the center, each group comprises 6 conductive contacts, which are sequentially marked as a conductive contact 1, a conductive contact 2, a conductive contact 3, a conductive contact 4, a conductive contact 5 and a conductive contact 6. The conductive contact 1 and the conductive contact 6 are grounded, the potential of the conductive contact A0 is 0 when the component is scanned, the conductive contact 2, the conductive contact 3, the conductive contact 4 and the conductive contact 5 are not grounded, the conductive contact a is the four, and the potential of the component is 1 when the component is scanned (as the picture on the far right side of fig. 3, the grounded conductive contact is represented by white, and the high potential contact is represented by black).

The surface of the specific combination surface B is provided with 3 groups of conductive contacts symmetrical about the center, each group comprises 6 conductive contacts which are sequentially marked as a conductive contact a, a conductive contact B, a conductive contact c, a conductive contact d, a conductive contact e and a conductive contact f. Wherein, the conductive contact B and the conductive contact e are grounded, and are conductive electric shock B0, and the potential of the component is 0 when the component is scanned. Conductive contact a, conductive contact c, conductive contact d and conductive contact f are not grounded, and the four are conductive contacts B, which have a potential of 1 when the component is scanned (as shown in the middle of fig. 3, ground conductive contact is represented by white, and high potential contact is represented by black).

When the component a and the component B are combined, as shown in the rightmost picture of fig. 3, the specific combining surface a and the specific combining surface B are in close contact, which may or may not bring part or all of the conductive contact a into contact with the conductive contact B. At this time: the scanning reading component a, the conductive contact B may enable part or all of the conductive contact a to communicate with the grounded conductive contact A0 (the conductive contact B may not enable the grounded conductive contact a to communicate with the conductive contact A0), and in summary, the potential of all of the conductive contacts a may form a character string set a. For example, as shown in the right-most picture of fig. 3, the conductive contact e connects the conductive contact 6 of 0 potential with the conductive contact 5 of high potential, and the potentials of all conductive contacts a may form a character string set a as 1110. When the component a and the component B are combined, the specific combining surface a and the specific combining surface B are closely contacted, and part or all of the conductive contact a may be brought into contact with the conductive contact B, or none of the conductive contact a may be brought into contact with the conductive contact B. At this time: the scan-reading component B, the conductive contact a may cause a part or all of the grounded conductive contact B to communicate with the grounded conductive contact B0 (the conductive contact a may not cause the grounded conductive contact B to communicate with the conductive contact B0), and in summary, the electric potential of all the conductive contacts B forms a character string set B. For example, as shown in the rightmost picture of fig. 3, the conductive contact 2 makes the low-potential conductive contact B communicate with the high-potential conductive contact c, and the conductive contact 5 makes the low-potential conductive contact e communicate with the high-potential conductive contact d, so that the potentials of all the conductive contacts B can form a character string set B of 1001. String set A "1110" and string set B "1001" are an associated (mapping rule compliant) set of string sets.

Fig. 4 uses the same parts a and B as fig. 3, except that part B is rotated by an angle with respect to fig. 3 (in reality, the position where the two parts are combined again after each separation is random, i.e., the change angle is random). When the component a and the component B are combined, as shown in the rightmost picture of fig. 4, the specific combining surface a and the specific combining surface B are in close contact, which may or may not bring part or all of the conductive contact a into contact with the conductive contact A0. At this time: the scan reads component a (component a powered on, component B powered off, or by a software setting, does not read information of component B), conductive contact B may place partially or fully grounded conductive contact a in communication with grounded conductive contact A0 (conductive contact B may also not place grounded conductive contact A0 in communication with conductive contact a of high potential), and in summary, the potential of all conductive contacts a may form a string set a. For example, as shown in the right-most picture of fig. 4, the absence of the conductive contact B causes the conductive contact A0 of the 0 potential to communicate with the conductive contact a of the high potential, and the potentials of all the conductive contacts a may form one character string set a of 1111. When the component a and the component B are combined, the specific combining surface a and the specific combining surface B are closely contacted, and part or all of the conductive contact B may be brought into contact with the conductive contact B0, or no conductive contact B may be brought into contact with the conductive contact B0. At this time: the scan reads component B (component B powered on, component a powered off, or by a software setting, does not read component a's information), conductive contact a may place some or all of grounded conductive contact B in communication with grounded conductive contact B0 (conductive contact a may also not place grounded conductive contact B in communication with grounded conductive contact B0), and in summary, the potential of all conductive contact B forms a string set B. For example, as shown in the right-most picture of fig. 4, the conductive contact 2 connects the conductive contact B with a low potential to the conductive contact a with a high potential, and the potentials of all the conductive contacts B may form a character string set B of 0111. String set A "1111" and string set B "0111" are an associated (mapping rule compliant) set of strings.

And so on, the component A is fixed, the component B rotates for one circle, and a plurality of pairs of associated character string sets A and character string sets B can be obtained, and the pairs of character string sets A and character string sets B form a mapping rule which can be stored by a background or a server and is used for verifying whether the component A and the component B are real or not in the future (namely, a plurality of groups of corresponding character string sets A and character string sets B form a matching rule of the character string sets A and the character string sets B). In this embodiment, the above-mentioned pairs of associated strings are sorted, each string set a corresponds to only a limited number of string sets B, and each string set B corresponds to only a limited number of string sets a, and this correspondence may form a mapping table of string sets a and B, that is, a matching rule of the string sets a and B.

The background system stores the matching rules of the character string set A and the character string set B. And after the character string set A and the character string set B are read, transmitting the character string set A and the character string set B to the background system.

And if the two sections of character strings acquired by the background system conform to the matching rules of the character string set A and the character string set B after the part A to be verified and the part B to be verified are read, judging that the part A to be verified and the part B to be verified are the combined part A and part B. For example, in this embodiment, the component a may read the character string 1111, and the component B to be verified may read the character string 0111, and it may be determined that the component a to be verified and the component B to be verified are the component a and the component B combined together.

And if the two sections of character strings acquired by the background system do not accord with the matching rule of the character string set A and the character string set B after the part A to be verified and the part B to be verified are read, judging that the part A to be verified and the part B to be verified are not combined together. For example, in the present embodiment, the component a may read the character string 1111, the component B to be verified may read the character string 1100 instead of the character string 0111 (the character string 1111 and the character string 1100 are unlikely to appear in pairs, and are not within the matching rule range), it may be judged whether the component a to be verified and the component B to be verified are the component a and the component B combined together, at least one of the component a and the component B being counterfeit.

Example 14:

The main scheme of this embodiment is the same as embodiment 13, and a conductive pattern (embodiment 2) is adopted, specifically, the component a has a specific bonding surface a (fig. 1). The component B has a specific binding surface B (fig. 2), which forms an authentication system (identRAS). Further, all the conductive contacts on the surface of the specific bonding surface A are conductive contacts A, and no conductive pattern A is formed by the conductive contacts A0 and the conductive contacts A. The surface of the specific bonding surface B is provided with a plurality of conductive contacts B, no conductive contact B0 and a conductive pattern B formed by the plurality of conductive contacts B. When the component a and the component B are bonded, the specific bonding surface a and the specific bonding surface B are brought into close contact. At this time, since some or all of the conductive contacts a are in contact with the conductive contacts B, in the conductive pattern a, some of the conductive contacts a are connected to each other, and the serial numbers of the conductive contacts a connected to each other form the information a (i.e., the topological connection relationship of the conductive contacts a forms the information a, it should be noted that the topological connection relationship may also be an adjacent matrix of the graph with the conductive contacts a as vertices, and the conductive contacts B randomly connect the conductive contacts a, i.e., form edges in the graph). Meanwhile, as part or all of the conductive contacts B are in contact with the conductive contacts a, part of the conductive contacts B are mutually communicated in the conductive pattern B, and the serial numbers of the mutually communicated conductive contacts B form information B (i.e. the topological connection relationship of each conductive contact B forms information B, it should be noted that the topological connection relationship may also be an adjacent matrix of a graph taking the conductive contact B as a vertex, and the conductive contacts a are randomly communicated with the conductive contacts B, i.e. form edges in the graph).

In this embodiment, the present invention is applicable to a variety of applications. The surface of the specific combination surface A is provided with 3 groups of conductive contacts A which are symmetrical about the center, each group comprises a conductive pattern A formed by 6 conductive contacts A, and each conductive contact in the pattern is sequentially marked as a conductive contact 1, a conductive contact 2, a conductive contact 3, a conductive contact 4, a conductive contact 5 and a conductive contact 6.

The surface of the specific combination surface B is provided with 3 groups of conductive contacts B which are symmetrical about the center, each group comprises a conductive pattern B formed by 6 conductive contacts B, and each conductive contact in the pattern is sequentially marked as a conductive contact a, a conductive contact B, a conductive contact c, a conductive contact d, a conductive contact e and a conductive contact f.

When the component a and the component B are combined, as shown in the rightmost picture of fig. 3, the specific combining surface a and the specific combining surface B are in close contact, which may or may not bring part or all of the conductive contact a into contact with the conductive contact B. At this time: the scanning and reading component A, the serial number set of the conductive contacts A which are mutually communicated forms information A (namely the topological connection relation of the conductive contacts), and in summary, the electric potential of all the conductive contacts A can form a character string set A. For example, as shown in the right-most picture of fig. 3, conductive contacts 2 and 3 are connected by conductive contact b, and conductive contacts 4-6 are connected together by conductive contacts d and e, at which time information a is represented as: several fields connected with a short "-" each field is a conductive contact a (representing one of the topological connections of conductive contacts a) that are connected together, i.e. information a is 1-23456. Meanwhile, the conductive contact 2 connects the conductive contacts B and c, and the conductive contact 5 connects the conductive contacts d and e, and at this time, the information B is a serial number set (representing one of topological connection relations of the conductive contacts B) of the conductive contacts B connected together, that is, the information B is a-bc-de-f. String set A "1-23456" and string set B "a-bc-de-f" are an associated (mapping rule compliant) set of string sets.

Fig. 4 uses the same parts a and B as fig. 3, except that part B is rotated by an angle with respect to fig. 3 (in reality, the two parts are rotated by random angles). When the component a and the component B are combined, as shown in the rightmost picture of fig. 4, the specific combining surface a and the specific combining surface B are in close contact, and part or all of the conductive contact a may be brought into contact with the conductive contact B, or there may be no conductive contact a into contact with the conductive contact B. At this time: the scanning and reading component A, the serial number set of the conductive contacts A which are mutually communicated forms information A (namely the topological connection relation of the conductive contacts), and in summary, the electric potential of all the conductive contacts A can form a character string set A. For example, as shown in the right-most picture of fig. 3, conductive contacts 2 and 3 are connected by conductive contact b, and conductive contacts 4 and 5 are connected together by conductive contact d, at which time information a is represented as: several fields are connected with a short "-" each field being a conductive contact a (representing one of the topological connections of conductive contacts a) that are connected together, i.e. information a is 1-23-45-6. Meanwhile, the conductive contacts 2 connect the conductive contacts a and B, and the information B is a serial number set (representing one of topological connection relations of the conductive contacts B) of the conductive contacts B connected together, namely the information B is ab-c-d-e-f. The string set A "1-23-45-6" and the string set B "ab-c-d-e-f" are an associated (mapping rule compliant) set of strings.

And if the two sections of character strings acquired by the background system conform to the matching rules of the character string set A and the character string set B after the part A to be verified and the part B to be verified are read, judging that the part A to be verified and the part B to be verified are the combined part A and part B. For example, in this embodiment, the component a may read the character strings 1-23456, and the component B to be verified may read the character strings a-bc-de-f, and then it may be determined that the component a to be verified and the component B to be verified are the component a and the component B that are combined together.

And if the two sections of character strings acquired by the background system do not accord with the matching rule of the character string set A and the character string set B after the part A to be verified and the part B to be verified are read, judging that the part A to be verified and the part B to be verified are not combined together. For example, in this embodiment, the component a may read the character strings 1 to 23456, the component B to be verified may read the character strings abc to def instead of the character strings a to bc to de-f (the character strings 1 to 23456 and the character strings abc to def are unlikely to appear in pairs, and are not within the matching rule range), it may be judged whether the component a to be verified and the component B to be verified are the component a and the component B to be combined together, and at least one of the component a and the component B is counterfeit.
