the matching result is that the identity content which is the same as the identity content of the first communication terminal is not matched in the recognition library, and the second communication terminal rejects the receiving request of the first communication terminal;
based on the processing policy, the present invention further provides a processing policy with higher security, specifically, the receiving request of the first communication end further includes an ID, each identity in the identification library corresponds to an ID tag, and the policy for the second communication end to process the receiving request of the first communication end based on the matching result is as follows:
the matching result is that the identity content which is the same as the identity content of the first communication terminal is matched in the identification library, the ID mark of the identity content which is the same as the identity content of the first communication terminal in the identification library is consistent with the ID of the first communication terminal, and the second communication terminal sends the corresponding content to the first communication terminal based on the receiving request of the first communication terminal;
the matching result is that the identity content which is the same as the identity content of the first communication terminal is not matched in the recognition library or the matching result is that the identity content which is the same as the identity content of the first communication terminal is matched in the recognition library, but the ID mark of the identity content which is the same as the identity content of the first communication terminal in the recognition library is not consistent with the ID of the first communication terminal, and the second communication terminal rejects the receiving request of the first communication terminal;

the identification base is stored in the cloud platform, the second communication terminal obtains the identity content of the first communication terminal from the identity identification information of the analysis receiving request and sends the identity content to the cloud platform, and the cloud platform matches the identity content of the first communication terminal with the stored identity content.
The method for generating the identity recognition information by the identity content in the invention comprises the following steps:
the identity content is a string of digital characters;
generating an identification boundary chain code based on the digital character, generating a boundary image based on the identification boundary chain code, and selecting any pixel point on the boundary image as a complex coding starting point to carry out coding again to obtain a complex boundary chain code; packing the recognition boundary chain code and the complex coding starting point as identity recognition information;

generating a boundary image based on the identified boundary chain code, and recoding the boundary image based on the complex coding start point to obtain a complex boundary chain code, wherein the digital characters of the complex boundary chain code are also identity content;
the method solves the problem of low security caused by directly sending the identity identification information, but the similar encryption mode still has the danger of identity content;
in order to solve the above problem, the present invention further provides a method for generating and decrypting identification information with higher security, comprising:
the method for generating the identity recognition information by the identity content comprises the following steps:
the identity content is a string of digital characters;
generating an identification boundary chain code based on the digital character, generating a boundary image based on the identification boundary chain code, and selecting a pixel point on the boundary image as a complex coding starting point based on a preset strategy to carry out coding again to obtain a complex boundary chain code; using the recognition boundary chain code as identity recognition information;
the method for the second communication terminal to analyze the identification information of the first communication terminal for receiving the request to obtain the identification content of the first communication terminal comprises the following steps:
generating a boundary image based on the identification boundary chain code, and selecting a complex coding starting point on the boundary image based on a preset strategy to re-code the boundary image to obtain a complex boundary chain code, wherein digital characters of the complex boundary chain code are also identity content;
the preset strategy is a common strategy of the first communication terminal and the second communication terminal and is preset in the first communication terminal and the second communication terminal;
the preset strategy can avoid being acquired by the outside, and even if the identification boundary chain code is acquired, the identification information is difficult to be obtained by recoding;
the present invention provides a predetermined strategy: taking the 10 th bit and the 11 th bit of the ID of the first communication end as serial numbers, and taking pixel points corresponding to the serial numbers as complex encoding starting points; specifically, a pixel point corresponding to a serial number generated when a boundary image is generated based on the identification of a boundary chain code is a complex coding starting point;
for example, if the serial number of the recognition boundary chain code of 1234567892334621686246 is 12, a 12 th pixel point is generated corresponding to the 11 th bit of the recognition boundary chain code, and the pixel point is used as the starting point of the complex encoding;
for the direction of the complex code, the backward direction is adopted by default, namely the same direction as the direction when the boundary chain code is identified to generate the boundary image;
for the case of wired communication between the first communication terminal and the second communication terminal, the requirement for identity identification is weak because a stable communication line is provided between the whole-course wired communication; the invention only considers the condition of wireless communication between a first communication terminal and a second communication terminal, and the establishment of the wireless communication also needs to be considered for the wireless communication, so the receiving request also comprises a time-frequency parameter which is a field used for scheduling information related to channel time allocation;
as shown in fig. 2, in this embodiment, the time-frequency parameters in the format of ESE of the traditional WiGig at least include: an element ID field 102, a length field 104, and a plurality of allocation fields 106. The element ID field 102 uniquely identifies the legacy ESE. The length field 104 specifies the number of octets (octets) in the multiple allocation field 106.
The allocation field 106 is a field indicating scheduling information related to channel time allocation (channel time allocation). The allocation field 106 includes an allocation control field 112, a BF (beamforming) control field 114, a source AID (association identifier) field 116, a destination AID field 118, an allocation start field 120, an allocation block duration field 122, a number of blocks field 126, and an allocation block period field 128.
The allocation control field 112 has: an allocation ID field 132, an allocation type field 134, a semi-static field 136, a truncatable field 138, an extensible field 140, and the like.
The allocation type field 134 indicates which of CBAP (contention based Access period) or SP (service period) the channel Access mechanism (Access mechanism) at the time of allocation is.
The source AID field 116 specifies the STA that starts channel access at SP or CBAP allocation. Alternatively, in the case of CBAP allocation, if all STAs are permitted to transmit at the time of CBAP allocation, the source AID field 116 is set to a broadcast AID.
The target AID field 118 specifies STAs that are predicted to communicate with the source STA at the time of allocation. Alternatively, the target AID field 118 is set to the broadcast AID in the case where it is predicted at the time of allocation that all STAs communicate with the source STA. When the value is set to a value other than 0, the assignment ID field 132 discriminates the communication time assignment (airtime assignment) from the source AID to the target AID. The allocation ID field 132 is set to 0 when CBAP allocation using the broadcast source AID and the broadcast target AID is used.
Except for the case of CBAP assignments using broadcast source AIDs and broadcast target AIDs, tuples (source AIDs, target AIDs, assignment IDs) uniquely distinguish assignments;
the semi-static field 136 indicates whether the allocation is semi-static (semi-static). The semi-static allocation is repeated for the same duration in the same time offset in several beacon intervals following the last received ESE containing the semi-static allocation. The truncatable field 138 and the extensible field 140 indicate whether the source STA and the target STA can request truncation of the SP (service period) and extension of the SP, respectively.
The allocation start field 120 indicates a timing (timing) at which the SP or CBAP starts. An allocation block duration field 122 indicates a duration of an allocation block for which allocation of an SP or allocation of a CBAP is performed and which does not exceed a boundary of a beacon interval;
the number of blocks field 126 contains the number of time blocks that constitute the allocation. The allocation block period field 128 contains the time between the beginning of 2 consecutive time blocks belonging to the same allocation. The allocation start field 120, the allocation block duration field 122, the number of blocks field 126, and the allocation block duration field 128 cooperatively specify the location of the allocation in the time domain.
