Specifically, the target device refers to any electronic device except a target mobile terminal and a target server, wherein the target mobile terminal refers to a mobile terminal installed with target application software, and the target server refers to a server communicated with the target mobile terminal.
Further, the mobile terminal ID is stored in the target mobile terminal and the association ID is stored in the target server.
Specifically, each ZZ λ The acquisition method of (a) can refer to steps S500-S540, and is not described herein.
S610, acquiring an intermediate mobile terminal ID list ZZ' according to ZZ.
Specifically, in step S610, the intermediate mobile terminal ID list is also acquired by:
s6101, when more than two identical original mobile terminal IDs exist in ZZ, reserving any one of the original mobile terminal IDs corresponding to the identical original mobile terminal ID in an original mobile terminal ID list, and deleting other original mobile terminal IDs corresponding to the identical original mobile terminal ID in ZZ;
s6102 obtaining ZZ λ ＝{Z λ1 、Z λ2 、Z λ3 、Z λ4 Z is }, where λ1 Refers to the original mobile terminal ID λ Is the first character string, Z λ2 Refers to the original mobile terminal ID λ And (Z) is the second character string of λ3 Refers to the original mobile terminal ID λ And (Z) is the third character string of λ4 Refers to the original mobile terminal ID λ A fourth string of (2);
s6103, as ZZ λ Corresponding time interval < Z λ2 Deleting ZZ in ZZ when the corresponding effective time is over λ Wherein ZZ λ The time interval acquisition method of (a) can refer to the time interval acquisition method of the target mobile terminal ID, Z λ2 The effective time obtaining method of (1) may refer to the effective time of the ID of the target mobile terminal and will not be described herein.

S620, obtaining the ratio K of the number h of the intermediate mobile terminal IDs corresponding to ZZ 'and the number K of the abnormal mobile terminal IDs corresponding to ZZ'.
Specifically, the intermediate mobile terminal ID refers to any one of the original mobile terminal IDs in the intermediate mobile terminal IDs.
Specifically, K meets the following conditions: k=h 0 /h，h 0 The abnormal mobile terminal IDs are corresponding to ZZ', and the abnormal mobile terminal IDs are the middle mobile terminal IDs in the middle mobile terminal ID list, wherein the difference between the time interval of the mobile terminal IDs and the preset time period of the mobile terminal IDs is smaller than the random time period of the mobile terminal IDs.
S630, when h is smaller than or equal to a preset mobile terminal ID quantity threshold h 'or K is smaller than or equal to a preset ratio threshold K', feeding back prompt information to target equipment, wherein the prompt information is used for representing that an original mobile terminal ID list cannot be processed.
S640, when h is greater than a preset mobile terminal ID quantity threshold h 'and K is greater than a preset ratio threshold K', a target mobile terminal ID list is obtained.
Specifically, the step S640 further includes the steps of:
s6401, obtaining all associated IDs corresponding to any intermediate mobile terminal ID in ZZ 'and constructing an associated ID list corresponding to ZZ' based on all associated IDs corresponding to any intermediate mobile terminal ID in ZZ ', wherein the associated ID list corresponding to ZZ' is subjected to associated ID duplication removal processing, and a method of duplication removal processing is known to a person skilled in the art and is not described herein.
S6402, according to the associated ID list corresponding to ZZ', a target associated ID list is obtained from a mapping table between the mobile terminal ID and the associated ID.
Specifically, the value of h 'ranges from 800 to 3000, and preferably, the value of h' is 1000.
