  • Patent number: 12294572
    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.

  • Publication number: 20230071847
    Abstract: An information verification method based on a cloud security technology is provided. The method includes: obtaining key agreement data; transmitting, to a terminal device, key agreement data based on which encryption processing is performed on to-be-verified information for a target application by using a second random number and a public key and a first random number included in the key agreement data, to obtain to-be-verified ciphertext information; receiving the to-be-verified ciphertext information from the terminal device; performing decryption processing on the to-be-verified ciphertext information, to obtain a first information digest; matching the first information digest with a second information digest, to obtain an information verification result; and transmitting the information verification result to the terminal device.

  • Patent number: 9823773
    Abstract: A handheld device and a method for implementing input area position adjustment on the handheld device includes, when detecting that a user executes a touch operation on a touchscreen of the handheld device, the handheld device determines, according to a relative position relationship between coordinates of contact points sensed by the touchscreen, whether the user executes the touch operation by a left hand or a right hand, and then, according to a result of the determining, displays, on a left side or a right side of the touchscreen, an input area that is currently displayed on the touchscreen, such that it is convenient for the user to perform inputting by one hand, thereby resolving a problem in the prior art that user operations are relatively cumbersome because a user needs to tap a specific touch area to implement input area position adjustment.
