Methods and systems for recognizing disguised device

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• in response to an interaction with an application installed on a device, receiving environment information and a device ID associated with the device;
• determining whether the device ID exists in a pre-stored association table of a unique environment identifier and a device ID;
• and
• in response to determining that the device ID does not exist in the association table:
• calculating a unique environment identifier associated with the device based on the environment information;
• searching the association table for a device ID associated with the unique environment identifier;
• and
• determining, based on a quantity of different identified device IDs associated with the unique environment identifier, whether the device is disguised.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• in response to an interaction with an application installed on a device, receiving environment information and a device ID associated with the device;
• determining whether the device ID exists in a pre-stored association table of a unique environment identifier and a device ID;
• and
• in response to determining that the device ID does not exist in the association table:
• calculating a unique environment identifier associated with the device based on the environment information;
• searching the association table for a device ID associated with the unique environment identifier;
• and
• determining, based on a quantity of different identified device IDs associated with the unique environment identifier, whether the device is disguised.
