A method and system for user device identification are provided, the method including: obtaining a number of device records in chronological order (S1); calculating the time domain characteristic information of the attribute values changed in the device records (S2); according to the time domain characteristic information of the attribute values changed in the device records, calculating the difference value of the attribute changed (S3); according to the difference value of all the attributes in the device records, calculating the similarity of the device records (S4); identifying whether the device records belong to the same device according to the similarity of the device records (S5). Compared with the prior art, the above method and system for user device identification are on the basis of all the attributes of the device, according to the similarity weight adjusted dynamically with the time series, the similarity of the device records is calculated accurately, and the leakage rate is reduced effectively. |
