Method and system for generating unique identifier of device

Abstract

The invention discloses a method and a system for generating a unique identifier of a device. The unique identifier of a mobile device is generated through software and hardware information, and data sharing among APPs in a platform is realized through the unique identifier of the mobile device. According to the technical scheme, the method comprises: 1, obtaining an equipment identifier through cross-application cache, and if the equipment identifier is successfully obtained and meets the rule that a preset character serves as an initial field, directly executing the step 4; 2, generating a character string serving as a unique identifier of the equipment based on the acquired equipment identifier; 3, caching the character string which is generated in the step 2 and is used as the unique identifier of the equipment through cross-application caching; and 4, outputting the character string generated in the step 2 or obtained in the step 1, and supplying the character string to a business party as a unique identifier of the equipment.

Description

technical field [0001] The invention relates to a device identifier generation technology, in particular to a method and a system for generating a mobile device unique identifier through software and hardware information, which is applied in the fields of mobile terminal development, mobile payment risk control, user data analysis and the like. Background technique [0002] As the country and individuals attach importance to information security, the identifiers that uniquely identify mobile devices commonly used in the industry, such as IMEI, Mac address, IDFA, etc., are prohibited from being read; and if information such as UUID provided by a third party is used, it is also There may be risks of being replaced or replaced, and the APP Store refuses to put it on the shelves, and there may be risks such as the inability to uniquely identify user devices, thereby incapable of real-time monitoring of transaction behaviors, and inability to accurately identify fraudulent behavio...
