Abstract: Various aspects involve determining legitimacy of an email address for risk assessment or other purposes. For instance, a risk assessment computing system receives a risk assessment query that identifies an email address. The risk assessment computing system determines a set of features for the email address. For each feature, the risk assessment computing system calculates an illegitimacy score by calculating a deviation of the feature from an expected safe value for the feature that is determined from historical email addresses. The risk assessment computing system aggregates the illegitimacy scores of the plurality of features into an aggregated illegitimacy score and further transmits a legitimacy risk value to a remote computing system. The legitimacy risk value indicates the aggregated illegitimacy score and can be used in controlling access of a computing device associated with the email address to one or more interactive computing environments.

Abstract: An information verification method based on a cloud security technology is provided. Before transmitting to-be-verified information including user information, a terminal device performs encryption processing on the to-be-verified information by using random numbers and a public key issued by a verification server, to obtain to-be-verified ciphertext information, which is to be used throughout transmission for logging into a server of a third-party application. The server of the third-party application cannot decrypt the to-be-verified information and the to-be-verified information may be obtained only by the verification server. The verification server transmits an application login success message to the terminal device based on decryption processing on the to-be-verified ciphertext information. In this way, the server of the third-party application may be logged in to without exposing privacy information of a user to the third-party application, thereby improving the security of identity verification.
