Method and device for constructing trusted portrait based on privacy calculation and electronic equipment

The invention provides a method and device for constructing a trusted portrait based on privacy calculation and electronic equipment, and relates to the technical field of data processing. The method comprises the following specific steps: generating a target key, and encrypting to-be-processed data according to the target key to generate a target information abstract; generating a storage table according to a mapping relation between the target information abstract and the to-be-processed data; inputting the target information abstract into a trusted computing engine for operation to generate a trusted portrait; and obtaining a target information abstract corresponding to the credible portrait, and obtaining to-be-processed data corresponding to the credible portrait according to the storage table. According to the method, the to-be-processed data is encrypted through the target key and then input into the trusted computing engine for trusted portrait operation, so that the confidentiality of the to-be-proce
