The invention provides a risk identification method and device for a service request and processing equipment. The binary bitmap is used for storing the corresponding relation information between thefeatures and the user; based on the binary bitmap, the corresponding relationship between each feature in the service request and each user can be quickly determined; matching calculation is performedon the binary bitmaps of different feature parameter combinations by using a preset strategy, so that a risk user set corresponding to each feature in the service request can be determined, and the risk identification result of the service request can be further rapidly determined based on the risk user set. Characteristic user information is stored by using a binary bitmap, so that the storage cost can be greatly reduced, offline calculation is not needed, and an online database is not needed either.
