The present invention relates to an information processing method, apparatus, and system. The method includes: receiving text information; performing calculation on the text information by using a first model to obtain a public sensitivity weight value corresponding to the text information; determining whether the public sensitivity weight value is greater than a first preset threshold; and if yes, displaying first processing prompt information indicating that the text information includes sensitive information; if no, performing calculation on the text information by using a second model to obtain an individual sensitivity weight value corresponding to the text information; and determining whether the individual sensitivity weight value is greater than a second preset threshold; and if yes, displaying second processing prompt information indicating that the text information includes sensitive information. The present invention enables a terminal to automatically detect whether text information involves sensitive information, thereby improving security of a crowdsourcing application.
